Device Monitors Wind Speed at Cherry Branch Ferry Terminal by NCDOTcommunications

1

This device shows that wind speeds detected at the Cherry Branch Ferry Terminal on the Neuse River measured about 52 mph this morning, with gusts of up to 64 mph. These high winds from Hurricane Sandy have elevated the water levels at the terminal, forcing the suspension of ferry service until conditions improve.

Spaceflight (or space flight) is ballistic flight into or through outer space. Spaceflight can occur with spacecraft with or without humans on board. Yuri Gagarin of the Soviet Union was the first human to conduct a spaceflight. Examples of human spaceflight include the U.S. Apollo Moon landing and Space Shuttle programs and the Russian Soyuz program, as well as the ongoing International Space Station. Examples of unmanned spaceflight include space probes that leave Earth orbit, as well as satellites in orbit around Earth, such as communications satellites. These operate either by telerobotic control or are fully autonomous.

Spaceflight is used in space exploration, and also in commercial activities like space tourism and satellite telecommunications. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other Earth observation satellites.

A spaceflight typically begins with a rocket launch, which provides the initial thrust to overcome the force of gravity and propels the spacecraft from the surface of the Earth. Once in space, the motion of a spacecraft – both when unpropelled and when under propulsion – is covered by the area of study called astrodynamics. Some spacecraft remain in space indefinitely, some disintegrate during atmospheric reentry, and others reach a planetary or lunar surface for landing or impact.

History

Main articles: History of spaceflight and Timeline of spaceflight

Tsiolkovsky, early space theorist

The first theoretical proposal of space travel using rockets was published by Scottish astronomer and mathematician William Leitch, in an 1861 essay "A Journey Through Space".[1] More well-known (though not widely outside Russia) is Konstantin Tsiolkovsky's work, "Исследование мировых пространств реактивными приборами" (The Exploration of Cosmic Space by Means of Reaction Devices), published in 1903.

Spaceflight became an engineering possibility with the work of Robert H. Goddard's publication in 1919 of his paper A Method of Reaching Extreme Altitudes. His application of the de Laval nozzle to liquid fuel rockets improved efficiency enough for interplanetary travel to become possible. He also proved in the laboratory that rockets would work in the vacuum of space;[specify] nonetheless, his work was not taken seriously by the public. His attempt to secure an Army contract for a rocket-propelled weapon in the first World War was defeated by the November 11, 1918 armistice with Germany. Working with private financial support, he was the first to launch a liquid-fueled rocket in 1926. Goddard's paper was highly influential on Hermann Oberth, who in turn influenced Wernher von Braun. Von Braun became the first to produce modern rockets as guided weapons, employed by Adolf Hitler. Von Braun's V-2 was the first rocket to reach space, at an altitude of 189 kilometers (102 nautical miles) on a June 1944 test flight.[2]

Tsiolkovsky's rocketry work was not fully appreciated in his lifetime, but he influenced Sergey Korolev, who became the Soviet Union's chief rocket designer under Joseph Stalin, to develop intercontinental ballistic missiles to carry nuclear weapons as a counter measure to United States bomber planes. Derivatives of Korolev's R-7 Semyorka missiles were used to launch the world's first artificial Earth satellite, Sputnik 1, on October 4, 1957, and later the first human to orbit the Earth, Yuri Gagarin in Vostok 1, on April 12, 1961.[3]

At the end of World War II, von Braun and most of his rocket team surrendered to the United States, and were expatriated to work on American missiles at what became the Army Ballistic Missile Agency. This work on missiles such as Juno I and Atlas enabled launch of the first US satellite Explorer 1 on February 1, 1958, and the first American in orbit, John Glenn in Friendship 7 on February 20, 1962. As director of the Marshall Space Flight Center, Von Braun oversaw development of a larger class of rocket called Saturn, which allowed the US to send the first two humans, Neil Armstrong and Buzz Aldrin, to the Moon and back on Apollo 11 in July 1969. Over the same period, the Soviet Union secretly tried but failed to develop the N1 rocket to give them the capability to land one person on the Moon.

Phases

Launch

Main article: Rocket launch

See also: List of space launch system designs

Rockets are the only means currently capable of reaching orbit or beyond. Other non-rocket spacelaunch technologies have yet to be built, or remain short of orbital speeds. A rocket launch for a spaceflight usually starts from a spaceport (cosmodrome), which may be equipped with launch complexes and launch pads for vertical rocket launches, and runways for takeoff and landing of carrier airplanes and winged spacecraft. Spaceports are situated well away from human habitation for noise and safety reasons. ICBMs have various special launching facilities.

A launch is often restricted to certain launch windows. These windows depend upon the position of celestial bodies and orbits relative to the launch site. The biggest influence is often the rotation of the Earth itself. Once launched, orbits are normally located within relatively constant flat planes at a fixed angle to the axis of the Earth, and the Earth rotates within this orbit.

A launch pad is a fixed structure designed to dispatch airborne vehicles. It generally consists of a launch tower and flame trench. It is surrounded by equipment used to erect, fuel, and maintain launch vehicles. Before launch, the rocket can weigh many hundreds of tonnes. The Space Shuttle Columbia, on STS-1, weighed 2,030 tonnes (4,480,000 lb) at take off.

Reaching space

The most commonly used definition of outer space is everything beyond the Kármán line, which is 100 kilometers (62 mi) above the Earth's surface. The United States sometimes defines outer space as everything beyond 50 miles (80 km) in altitude.

Rockets are the only currently practical means of reaching space. Conventional airplane engines cannot reach space due to the lack of oxygen. Rocket engines expel propellant to provide forward thrust that generates enough delta-v (change in velocity) to reach orbit.

For manned launch systems launch escape systems are frequently fitted to allow astronauts to escape in the case of emergency.

Alternatives

Main article: Non-rocket spacelaunch

Many ways to reach space other than rockets have been proposed. Ideas such as the space elevator, and momentum exchange tethers like rotovators or skyhooks require new materials much stronger than any currently known. Electromagnetic launchers such as launch loops might be feasible with current technology. Other ideas include rocket assisted aircraft/spaceplanes such as Reaction Engines Skylon (currently in early stage development), scramjet powered spaceplanes, and RBCC powered spaceplanes. Gun launch has been proposed for cargo.

Main articles: Escape velocity and Parking orbit

Launched in 1959, Luna 1 was the first known man-made object to achieve escape velocity from the Earth.[4] (replica pictured)

Achieving a closed orbit is not essential to lunar and interplanetary voyages. Early Russian space vehicles successfully achieved very high altitudes without going into orbit. NASA considered launching Apollo missions directly into lunar trajectories but adopted the strategy of first entering a temporary parking orbit and then performing a separate burn several orbits later onto a lunar trajectory. This costs additional propellant because the parking orbit perigee must be high enough to prevent reentry while direct injection can have an arbitrarily low perigee because it will never be reached.

However, the parking orbit approach greatly simplified Apollo mission planning in several important ways. It substantially widened the allowable launch windows, increasing the chance of a successful launch despite minor technical problems during the countdown. The parking orbit was a stable "mission plateau" that gave the crew and controllers several hours to thoroughly check out the spacecraft after the stresses of launch before committing it to a long lunar flight; the crew could quickly return to Earth, if necessary, or an alternate Earth-orbital mission could be conducted. The parking orbit also enabled translunar trajectories that avoided the densest parts of the Van Allen radiation belts.

Apollo missions minimized the performance penalty of the parking orbit by keeping its altitude as low as possible. For example, Apollo 15 used an unusually low parking orbit (even for Apollo) of 92.5 nmi by 91.5 nmi (171 km by 169 km) where there was significant atmospheric drag. But it was partially overcome by continuous venting of hydrogen from the third stage of the Saturn V, and was in any event tolerable for the short stay.

Robotic missions do not require an abort capability or radiation minimization, and because modern launchers routinely meet "instantaneous" launch windows, space probes to the Moon and other planets generally use direct injection to maximize performance. Although some might coast briefly during the launch sequence, they do not complete one or more full parking orbits before the burn that injects them onto an Earth escape trajectory.

Note that the escape velocity from a celestial body decreases with altitude above that body. However, it is more fuel-efficient for a craft to burn its fuel as close to the ground as possible; see Oberth effect and reference.[5] This is another way to explain the performance penalty associated with establishing the safe perigee of a parking orbit.

Plans for future crewed interplanetary spaceflight missions often include final vehicle assembly in Earth orbit, such as NASA's Project Orion and Russia's Kliper/Parom tandem.

Astrodynamics

Main article: Orbital mechanics

Astrodynamics is the study of spacecraft trajectories, particularly as they relate to gravitational and propulsion effects. Astrodynamics allows for a spacecraft to arrive at its destination at the correct time without excessive propellant use. An orbital maneuvering system may be needed to maintain or change orbits.

Non-rocket orbital propulsion methods include solar sails, magnetic sails, plasma-bubble magnetic systems, and using gravitational slingshot effects.

Transfer energy

The term "transfer energy" means the total amount of energy imparted by a rocket stage to its payload. This can be the energy imparted by a first stage of a launch vehicle to an upper stage plus payload, or by an upper stage or spacecraft kick motor to a spacecraft.[6][7]

Reentry

Main article: Atmospheric reentry

Vehicles in orbit have large amounts of kinetic energy. This energy must be discarded if the vehicle is to land safely without vaporizing in the atmosphere. Typically this process requires special methods to protect against aerodynamic heating. The theory behind reentry was developed by Harry Julian Allen. Based on this theory, reentry vehicles present blunt shapes to the atmosphere for reentry. Blunt shapes mean that less than 1% of the kinetic energy ends up as heat that reaches the vehicle, and the remainder heats up the atmosphere.

Landing

The Mercury, Gemini, and Apollo capsules all splashed down in the sea. These capsules were designed to land at relatively low speeds with the help of a parachute. Russian capsules for Soyuz make use of a big parachute and braking rockets to touch down on land. The Space Shuttle glided to a touchdown like a plane.

Recovery

After a successful landing the spacecraft, its occupants and cargo can be recovered. In some cases, recovery has occurred before landing: while a spacecraft is still descending on its parachute, it can be snagged by a specially designed aircraft. This mid-air retrieval technique was used to recover the film canisters from the Corona spy satellites.

Types

Uncrewed

See also: Uncrewed spacecraft and robotic spacecraft

The MESSENGER spacecraft at Mercury (artist's interpretation)

Uncrewed spaceflight (or unmanned) is all spaceflight activity without a necessary human presence in space. This includes all space probes, satellites and robotic spacecraft and missions. Uncrewed spaceflight is the opposite of manned spaceflight, which is usually called human spaceflight. Subcategories of uncrewed spaceflight are "robotic spacecraft" (objects) and "robotic space missions" (activities). A robotic spacecraft is an uncrewed spacecraft with no humans on board, that is usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe.

Uncrewed space missions use remote-controlled spacecraft. The first uncrewed space mission was Sputnik I, launched October 4, 1957 to orbit the Earth. Space missions where other animals but no humans are on-board are considered uncrewed missions.

Benefits

Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. Telerobotics also allows exploration of regions that are vulnerable to contamination by Earth micro-organisms since spacecraft can be sterilized. Humans can not be sterilized in the same way as a spaceship, as they coexist with numerous micro-organisms, and these micro-organisms are also hard to contain within a spaceship or spacesuit.

Telepresence

Telerobotics becomes telepresence when the time delay is short enough to permit control of the spacecraft in close to real time by humans. Even the two seconds light speed delay for the Moon is too far away for telepresence exploration from Earth. The L1 and L2 positions permit 400-millisecond round trip delays, which is just close enough for telepresence operation. Telepresence has also been suggested as a way to repair satellites in Earth orbit from Earth. The Exploration Telerobotics Symposium in 2012 explored this and other topics.[8]

Human

Main article: Human spaceflight

ISS crew member stores samples

The first human spaceflight was Vostok 1 on April 12, 1961, on which cosmonaut Yuri Gagarin of the USSR made one orbit around the Earth. In official Soviet documents, there is no mention of the fact that Gagarin parachuted the final seven miles.[9] Currently, the only spacecraft regularly used for human spaceflight are the Russian Soyuz spacecraft and the Chinese Shenzhou spacecraft. The U.S. Space Shuttle fleet operated from April 1981 until July 2011. SpaceShipOne has conducted two human suborbital spaceflights.

Sub-orbital

Main article: Sub-orbital spaceflight

The International Space Station in Earth orbit after a visit from the crew of STS-119

On a sub-orbital spaceflight the spacecraft reaches space and then returns to the atmosphere after following a (primarily) ballistic trajectory. This is usually because of insufficient specific orbital energy, in which case a suborbital flight will last only a few minutes, but it is also possible for an object with enough energy for an orbit to have a trajectory that intersects the Earth's atmosphere, sometimes after many hours. Pioneer 1 was NASA's first space probe intended to reach the Moon. A partial failure caused it to instead follow a suborbital trajectory to an altitude of 113,854 kilometers (70,746 mi) before reentering the Earth's atmosphere 43 hours after launch.

The most generally recognized boundary of space is the Kármán line 100 km above sea level. (NASA alternatively defines an astronaut as someone who has flown more than 50 miles (80 km) above sea level.) It is not generally recognized by the public that the increase in potential energy required to pass the Kármán line is only about 3% of the orbital energy (potential plus kinetic energy) required by the lowest possible Earth orbit (a circular orbit just above the Kármán line.) In other words, it is far easier to reach space than to stay there. On May 17, 2004, Civilian Space eXploration Team launched the GoFast Rocket on a suborbital flight, the first amateur spaceflight. On June 21, 2004, SpaceShipOne was used for the first privately funded human spaceflight.

Point-to-point

Point-to-point is a category of sub-orbital spaceflight in which a spacecraft provides rapid transport between two terrestrial locations. Consider a conventional airline route between London and Sydney, a flight that normally lasts over twenty hours. With point-to-point suborbital travel the same route could be traversed in less than one hour.[10] While no company offers this type of transportation today, SpaceX has revealed plans to do so as early as the 2020s using its BFR vehicle.[11] Suborbital spaceflight over an intercontinental distance requires a vehicle velocity that is only a little lower than the velocity required to reach low Earth orbit.[12] If rockets are used, the size of the rocket relative to the payload is similar to an Intercontinental Ballistic Missile (ICBM). Any intercontinental spaceflight has to surmount problems of heating during atmosphere re-entry that are nearly as large as those faced by orbital spaceflight.

Orbital

Main article: Orbital spaceflight

Apollo 6 heads into orbit

A minimal orbital spaceflight requires much higher velocities than a minimal sub-orbital flight, and so it is technologically much more challenging to achieve. To achieve orbital spaceflight, the tangential velocity around the Earth is as important as altitude. In order to perform a stable and lasting flight in space, the spacecraft must reach the minimal orbital speed required for a closed orbit.

Interplanetary

Main article: Interplanetary spaceflight

Interplanetary travel is travel between planets within a single planetary system. In practice, the use of the term is confined to travel between the planets of our Solar System.

Interstellar

Main article: Interstellar travel

Five spacecraft are currently leaving the Solar System on escape trajectories, Voyager 1, Voyager 2, Pioneer 10, Pioneer 11, and New Horizons. The one farthest from the Sun is Voyager 1, which is more than 100 AU distant and is moving at 3.6 AU per year.[13] In comparison, Proxima Centauri, the closest star other than the Sun, is 267,000 AU distant. It will take Voyager 1 over 74,000 years to reach this distance. Vehicle designs using other techniques, such as nuclear pulse propulsion are likely to be able to reach the nearest star significantly faster. Another possibility that could allow for human interstellar spaceflight is to make use of time dilation, as this would make it possible for passengers in a fast-moving vehicle to travel further into the future while aging very little, in that their great speed slows down the rate of passage of on-board time. However, attaining such high speeds would still require the use of some new, advanced method of propulsion.

Intergalactic

Main article: Intergalactic travel

Intergalactic travel involves spaceflight between galaxies, and is considered much more technologically demanding than even interstellar travel and, by current engineering terms, is considered science fiction.

Spacecraft

Main article: Spacecraft

An Apollo Lunar Module on the lunar surface

Spacecraft are vehicles capable of controlling their trajectory through space.

The first 'true spacecraft' is sometimes said to be Apollo Lunar Module,[14] since this was the only manned vehicle to have been designed for, and operated only in space; and is notable for its non aerodynamic shape.

Propulsion

Main article: Spacecraft propulsion

Spacecraft today predominantly use rockets for propulsion, but other propulsion techniques such as ion drives are becoming more common, particularly for unmanned vehicles, and this can significantly reduce the vehicle's mass and increase its delta-v.

Launch systems

The first reusable spacecraft, the X-15, was air-launched on a suborbital trajectory on July 19, 1963. The first partially reusable orbital spacecraft, the Space Shuttle, was launched by the USA on the 20th anniversary of Yuri Gagarin's flight, on April 12, 1981. During the Shuttle era, six orbiters were built, all of which have flown in the atmosphere and five of which have flown in space. The Enterprise was used only for approach and landing tests, launching from the back of a Boeing 747 and gliding to deadstick landings at Edwards AFB, California. The first Space Shuttle to fly into space was the Columbia, followed by the Challenger, Discovery, Atlantis, and Endeavour. The Endeavour was built to replace the Challenger, which was lost in January 1986. The Columbia broke up during reentry in February 2003.

The first automatic partially reusable spacecraft was the Buran (Snowstorm), launched by the USSR on November 15, 1988, although it made only one flight. This spaceplane was designed for a crew and strongly resembled the US Space Shuttle, although its drop-off boosters used liquid propellants and its main engines were located at the base of what would be the external tank in the American Shuttle. Lack of funding, complicated by the dissolution of the USSR, prevented any further flights of Buran.

Per the Vision for Space Exploration, the Space Shuttle was retired in 2011 due mainly to its old age and high cost of the program reaching over a billion dollars per flight. The Shuttle's human transport role is to be replaced by the partially reusable Crew Exploration Vehicle (CEV) no later than 2021. The Shuttle's heavy cargo transport role is to be replaced by expendable rockets such as the Evolved Expendable Launch Vehicle (EELV) or a Shuttle Derived Launch Vehicle.

Scaled Composites SpaceShipOne was a reusable suborbital spaceplane that carried pilots Mike Melvill and Brian Binnie on consecutive flights in 2004 to win the Ansari X Prize. The Spaceship Company has built its successor SpaceShipTwo. A fleet of SpaceShipTwos operated by Virgin Galactic planned to begin reusable private spaceflight carrying paying passengers (space tourists) in 2008, but this was delayed due to an accident in the propulsion development.[15]

Challenges

Main article: Effect of spaceflight on the human body

Space disasters

Main article: Space accidents and incidents

All launch vehicles contain a huge amount of energy that is needed for some part of it to reach orbit. There is therefore some risk that this energy can be released prematurely and suddenly, with significant effects. When a Delta II rocket exploded 13 seconds after launch on January 17, 1997, there were reports of store windows 10 miles (16 km) away being broken by the blast.[16]

Space is a fairly predictable environment, but there are still risks of accidental depressurization and the potential failure of equipment, some of which may be very newly developed.

In 2004 the International Association for the Advancement of Space Safety was established in the Netherlands to further international cooperation and scientific advancement in space systems safety.[17]

Weightlessness

Main article: Weightlessness

Astronauts on the ISS in weightless conditions. Michael Foale can be seen exercising in the foreground.

In a microgravity environment such as that provided by a spacecraft in orbit around the Earth, humans experience a sense of "weightlessness." Short-term exposure to microgravity causes space adaptation syndrome, a self-limiting nausea caused by derangement of the vestibular system. Long-term exposure causes multiple health issues. The most significant is bone loss, some of which is permanent, but microgravity also leads to significant deconditioning of muscular and cardiovascular tissues.

Radiation

Once above the atmosphere, radiation due to the Van Allen belts, solar radiation and cosmic radiation issues occur and increase. Further away from the Earth, solar flares can give a fatal radiation dose in minutes, and the health threat from cosmic radiation significantly increases the chances of cancer over a decade exposure or more.[18]

Life support

Main article: Life support system

In human spaceflight, the life support system is a group of devices that allow a human being to survive in outer space. NASA often uses the phrase Environmental Control and Life Support System or the acronym ECLSS when describing these systems for its human spaceflight missions.[19] The life support system may supply: air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences such as radiation and micro-meteorites may also be necessary. Components of the life support system are life-critical, and are designed and constructed using safety engineering techniques.

Space weather

Main article: Space weather

Aurora australis and Discovery, May 1991.

Space weather is the concept of changing environmental conditions in outer space. It is distinct from the concept of weather within a planetary atmosphere, and deals with phenomena involving ambient plasma, magnetic fields, radiation and other matter in space (generally close to Earth but also in interplanetary, and occasionally interstellar medium). "Space weather describes the conditions in space that affect Earth and its technological systems. Our space weather is a consequence of the behavior of the Sun, the nature of Earth's magnetic field, and our location in the Solar System."[20]

Space weather exerts a profound influence in several areas related to space exploration and development. Changing geomagnetic conditions can induce changes in atmospheric density causing the rapid degradation of spacecraft altitude in Low Earth orbit. Geomagnetic storms due to increased solar activity can potentially blind sensors aboard spacecraft, or interfere with on-board electronics. An understanding of space environmental conditions is also important in designing shielding and life support systems for manned spacecraft.

Environmental considerations

Rockets as a class are not inherently grossly polluting. However, some rockets use toxic propellants, and most vehicles use propellants that are not carbon neutral. Many solid rockets have chlorine in the form of perchlorate or other chemicals, and this can cause temporary local holes in the ozone layer. Re-entering spacecraft generate nitrates which also can temporarily impact the ozone layer. Most rockets are made of metals that can have an environmental impact during their construction.

In addition to the atmospheric effects there are effects on the near-Earth space environment. There is the possibility that orbit could become inaccessible for generations due to exponentially increasing space debris caused by spalling of satellites and vehicles (Kessler syndrome). Many launched vehicles today are therefore designed to be re-entered after use.

Stained glass Masonic Square and Compasses hang at the foot of my bed.

Masonic Square and Compasses.

The Square and Compasses (or, more correctly, a square and a set of compasses joined together) is the single most identifiable symbol of Freemasonry. Both the square and compasses are architect's tools and are used in Masonic ritual as emblems to teach symbolic lessons. Some Lodges and rituals explain these symbols as lessons in conduct: for example, Duncan's Masonic Monitor of 1866 explains them as: "The square, to square our actions; The compasses, to circumscribe and keep us within bounds with all mankind".

However, as Freemasonry is non-dogmatic, there is no general interpretation for these symbols (or any Masonic symbol) that is used by Freemasonry as a whole.

Square and Compasses:

Source: Mackey's Encyclopedia of Freemasonry

These two symbols have been so long and so universally combined — to teach us, as says an early instruction, "to square our actions and to keep them within due bounds," they are so seldom seen apart, but are so kept together, either as two Great Lights, or as a jewel worn once by the Master of the Lodge, now by the Past Master—that they have come at last to be recognized as the proper badge of a Master Mason, just as the Triple Tau is of a Royal Arch Mason or the Passion Cross of a Knight Templar.

So universally has this symbol been recognized, even by the profane world, as the peculiar characteristic of Freemasonry, that it has recently been made in the United States the subject of a legal decision. A manufacturer of flour having made, in 1873, an application to the Patent Office for permission to adopt the Square and Compasses as a trade-mark, the Commissioner of Patents, .J. M. Thatcher, refused the permission as the mark was a Masonic symbol.

If this emblem were something other than precisely what it is—either less known", less significant, or fully and universally understood—all this might readily be admitted. But, Considering its peculiar character and relation to the public, an anomalous question is presented. There can be no doubt that this device, so commonly worn and employed by Masons, has an established mystic significance, universally recognized as existing; whether comprehended by all or not, is not material to this issue. In view of the magnitude and extent of the Masonic organization, it is impossible to divest its symbols, or at least this particular symbol—perhaps the best known of all—of its ordinary signification, wherever displaced, either as an arbitrary character or otherwise.

It will be universally understood, or misunderstood, as having a Masonic significance; and, therefore, as a trade-mark, must constantly work deception. Nothing could be more mischievous than to create as a monopoly, and uphold by the poser of lacy anything so calculated. as applied to purposes of trade. to be misinterpreted, to mislead all classes, and to constantly foster suggestions of mystery in affairs of business (see Infringing upon Freemasonry, also Imitative Societies, and Clandestine).

In a religious work by John Davies, entitled Summa Totalis, or All in All and the Same Forever, printed in 1607, we find an allusion to the Square and Compasses by a profane in a really Masonic sense. The author, who proposes to describe mystically the form of the Deity, says in his dedication:

Yet I this forme of formelesse Deity,

Drewe by the Squire and Compasse of our Creed.

In Masonic symbolism the Square and Compasses refer to the Freemason's duty to the Craft and to himself; hence it is properly a symbol of brotherhood, and there significantly adopted as the badge or token of the Fraternity.

Berage, in his work on the higher Degrees, Les plus secrets Mystéres des Hauts Grades, or The Most Secret Mysteries of the High Grades, gives a new interpretation to the symbol. He says: "The Square and the Compasses represent the union of the Old and New Testaments. None of the high Degrees recognize this interpretation, although their symbolism of the two implements differs somewhat from that of Symbolic Freemasonry.

The Square is with them peculiarly appropriated to the lower Degrees, as founded on the Operative Art; while the Compasses, as an implement of higher character and uses, is attributed to the Decrees, which claim to have a more elevated and philosophical foundation. Thus they speak of the initiate, when he passes from the Blue Lodge to the Lodge of Perfection, as 'passing from the Square to the Compasses,' to indicate a progressive elevation in his studies. Yet even in the high Degrees, the square and compasses combined retain their primitive signification as a symbol of brotherhood and as a badge of the Order."

Square and Compass:

Source: The Builder October 1916

By Bro. B. C. Ward, Iowa

Worshipful Master and Brethren: Let us behold the glorious beauty that lies hidden beneath the symbolism of the Square and Compass; and first as to the Square. Geometry, the first and noblest of the sciences, is the basis on which the superstructure of Masonry has been erected. As you know, the word "Geometry" is derived from two Greek words which mean "to measure the earth," so that Geometry originated in measurement; and in those early days, when land first began to be measured, the Square, being a right angle, was the instrument used, so that in time the Square began to symbolize the Earth. And later it began to symbolize, Masonically, the earthly-in man, that is man's lower nature, and still later it began to symbolize man's duty in his earthly relations, or his moral obligations to his Fellowmen. The symbolism of the Square is as ancient as the Pyramids. The Egyptians used it in building the Pyramids. The base of every pyramid is a perfect square, and to the Egyptians the Square was their highest and most sacred emblem. Even the Chinese many, many centuries ago used the Square to represent Good, and Confucius in his writings speaks of the Square to represent a Just man.

As Masons we have adopted the 47th Problem of Euclid as the rule by which to determine or prove a perfect Square. Many of us remember with what interest we solved that problem in our school days. The Square has become our most significant Emblem. It rests upon the open Bible on this altar; it is one of the three great Lights; and it is the chief ornament of the Worshipful Master. There is a good reason why this distinction has been conferred upon the Square. There can be nothing truer than a perfect Square--a right angle. Hence the Square has become an emblem of Perfection.

Now a few words as to the Compass: Astronomy was the second great science promulgated among men. In the process of Man's evolution there came a time when he began to look up to the stars and wonder at the vaulted Heavens above him. When he began to study the stars, he found that the Square was not adapted to the measurement of the Heavens. He must have circular measure; he needed to draw a circle from a central point, and so the Compass was employed. By the use of the Compass man began to study the starry Heavens, and as the Square primarily symbolized the Earth, the Compass began to symbolize the Heavens, the celestial canopy, the study of which has led men to think of God, and adore Him as the Supreme Architect of the Universe. In later times the Compass began to symbolize the spiritual or higher nature of man, and it is a significant fact that the circumference of a circle, which is a line without end, has become an emblem of Eternity and symbolizes Divinity; so the Compass, and the circle drawn by the Compass, both point men Heavenward and Godward.

The Masonic teaching concerning the two points of the Compass is very interesting and instructive. The novitiate in Masonry, as he kneels at this altar, and asks for Light sees the Square, which symbolizes his lower nature, he may well note the position of the Compass. As he takes another step, and asks for more Light, the position of the Compass is changed somewhat, symbolizing that his spiritual nature can, in some measure, overcome his evil tendencies. As he takes another step in Masonry, and asks for further Light, and hears the significant words, "and God said let there be Light, and there was Light," he sees the Compass in new light; and for the first time he sees the meaning, thus unmistakably alluding to the sacred and eternal truth that as the Heavens are higher than the Earth, so the spiritual is higher than the material, and the spiritual in man must have its proper place, and should be above his lower nature, and dominate all his thoughts and actions. That eminent Philosopher, Edmund Burke, once said, "It is ordained that men of intemperate passions cannot be free. Their passions forge the chains which bind them, and make them slaves." Burke was right. Masonry, through the beautiful symbolism of the Compass, tells us how we can be free men, by permitting the spiritual within us to overcome our evil tendencies, and dominate all our thoughts and actions. Brethren, sometimes in the silent quiet hour, as we think of this conflict between our lower and higher natures, we sometimes say in the words of another, "Show me the way and let me bravely climb to where all conflicts with the flesh shall cease. Show me that way. Show me the way up to a higher plane where my body shall be servant of my Soul. Show me that way."

Brethren, if that prayer expresses desire of our hearts, let us take heed to the beautiful teachings of the Compass, which silently and persistently tells each one of us,

"You should not in the valley stay

While the great horizons stretch away

The very cliffs that wall you round

Are ladders up to higher ground.

And Heaven draws near as you ascend,

The Breeze invites, the Stars befriend.

All things are beckoning to the Best,

Then climb toward God and find sweet Rest.”

The secrets of Freemasonry are concerned with its traditional modes of recognition. It is not a secret society, since all members are free to acknowledge their membership and will do so in response to enquiries for respectable reasons. Its constitutions and rules are available to the public. There is no secret about any of its aims and principles. Like many other societies, it regards some of its internal affairs as private matters for its members. In history there have been times and places where promoting equality, freedom of thought or liberty of conscience was dangerous. Most importantly though is a question of perspective. Each aspect of the craft has a meaning. Freemasonry has been described as a system of morality, veiled in allegory and illustrated by symbols. Such characteristics as virtue, honour and mercy, such virtues as temperance, fortitude, prudence and justice are empty clichés and hollow words unless presented within an ordered and closed framework. The lessons are not secret but the presentation is kept private to promote a clearer understanding in good time. It is also possible to view Masonic secrecy not as secrecy in and of itself, but rather as a symbol of privacy and discretion. By not revealing Masonic secrets, or acknowledging the many published exposures, freemasons demonstrate that they are men of discretion, worthy of confidences, and that they place a high value on their word and bond.

Masonic Square and Compasses.

The Square and Compasses (or, more correctly, a square and a set of compasses joined together) is the single most identifiable symbol of Freemasonry. Both the square and compasses are architect's tools and are used in Masonic ritual as emblems to teach symbolic lessons. Some Lodges and rituals explain these symbols as lessons in conduct: for example, Duncan's Masonic Monitor of 1866 explains them as: "The square, to square our actions; The compasses, to circumscribe and keep us within bounds with all mankind".

However, as Freemasonry is non-dogmatic, there is no general interpretation for these symbols (or any Masonic symbol) that is used by Freemasonry as a whole.

Square and Compasses:

Source: Mackey's Encyclopedia of Freemasonry

These two symbols have been so long and so universally combined — to teach us, as says an early instruction, "to square our actions and to keep them within due bounds," they are so seldom seen apart, but are so kept together, either as two Great Lights, or as a jewel worn once by the Master of the Lodge, now by the Past Master—that they have come at last to be recognized as the proper badge of a Master Mason, just as the Triple Tau is of a Royal Arch Mason or the Passion Cross of a Knight Templar.

So universally has this symbol been recognized, even by the profane world, as the peculiar characteristic of Freemasonry, that it has recently been made in the United States the subject of a legal decision. A manufacturer of flour having made, in 1873, an application to the Patent Office for permission to adopt the Square and Compasses as a trade-mark, the Commissioner of Patents, .J. M. Thatcher, refused the permission as the mark was a Masonic symbol.

If this emblem were something other than precisely what it is—either less known", less significant, or fully and universally understood—all this might readily be admitted. But, Considering its peculiar character and relation to the public, an anomalous question is presented. There can be no doubt that this device, so commonly worn and employed by Masons, has an established mystic significance, universally recognized as existing; whether comprehended by all or not, is not material to this issue. In view of the magnitude and extent of the Masonic organization, it is impossible to divest its symbols, or at least this particular symbol—perhaps the best known of all—of its ordinary signification, wherever displaced, either as an arbitrary character or otherwise.

It will be universally understood, or misunderstood, as having a Masonic significance; and, therefore, as a trade-mark, must constantly work deception. Nothing could be more mischievous than to create as a monopoly, and uphold by the poser of lacy anything so calculated. as applied to purposes of trade. to be misinterpreted, to mislead all classes, and to constantly foster suggestions of mystery in affairs of business (see Infringing upon Freemasonry, also Imitative Societies, and Clandestine).

In a religious work by John Davies, entitled Summa Totalis, or All in All and the Same Forever, printed in 1607, we find an allusion to the Square and Compasses by a profane in a really Masonic sense. The author, who proposes to describe mystically the form of the Deity, says in his dedication:

Yet I this forme of formelesse Deity,

Drewe by the Squire and Compasse of our Creed.

In Masonic symbolism the Square and Compasses refer to the Freemason's duty to the Craft and to himself; hence it is properly a symbol of brotherhood, and there significantly adopted as the badge or token of the Fraternity.

Berage, in his work on the higher Degrees, Les plus secrets Mystéres des Hauts Grades, or The Most Secret Mysteries of the High Grades, gives a new interpretation to the symbol. He says: "The Square and the Compasses represent the union of the Old and New Testaments. None of the high Degrees recognize this interpretation, although their symbolism of the two implements differs somewhat from that of Symbolic Freemasonry.

The Square is with them peculiarly appropriated to the lower Degrees, as founded on the Operative Art; while the Compasses, as an implement of higher character and uses, is attributed to the Decrees, which claim to have a more elevated and philosophical foundation. Thus they speak of the initiate, when he passes from the Blue Lodge to the Lodge of Perfection, as 'passing from the Square to the Compasses,' to indicate a progressive elevation in his studies. Yet even in the high Degrees, the square and compasses combined retain their primitive signification as a symbol of brotherhood and as a badge of the Order."

Square and Compass:

Source: The Builder October 1916

By Bro. B. C. Ward, Iowa

Worshipful Master and Brethren: Let us behold the glorious beauty that lies hidden beneath the symbolism of the Square and Compass; and first as to the Square. Geometry, the first and noblest of the sciences, is the basis on which the superstructure of Masonry has been erected. As you know, the word "Geometry" is derived from two Greek words which mean "to measure the earth," so that Geometry originated in measurement; and in those early days, when land first began to be measured, the Square, being a right angle, was the instrument used, so that in time the Square began to symbolize the Earth. And later it began to symbolize, Masonically, the earthly-in man, that is man's lower nature, and still later it began to symbolize man's duty in his earthly relations, or his moral obligations to his Fellowmen. The symbolism of the Square is as ancient as the Pyramids. The Egyptians used it in building the Pyramids. The base of every pyramid is a perfect square, and to the Egyptians the Square was their highest and most sacred emblem. Even the Chinese many, many centuries ago used the Square to represent Good, and Confucius in his writings speaks of the Square to represent a Just man.

As Masons we have adopted the 47th Problem of Euclid as the rule by which to determine or prove a perfect Square. Many of us remember with what interest we solved that problem in our school days. The Square has become our most significant Emblem. It rests upon the open Bible on this altar; it is one of the three great Lights; and it is the chief ornament of the Worshipful Master. There is a good reason why this distinction has been conferred upon the Square. There can be nothing truer than a perfect Square--a right angle. Hence the Square has become an emblem of Perfection.

Now a few words as to the Compass: Astronomy was the second great science promulgated among men. In the process of Man's evolution there came a time when he began to look up to the stars and wonder at the vaulted Heavens above him. When he began to study the stars, he found that the Square was not adapted to the measurement of the Heavens. He must have circular measure; he needed to draw a circle from a central point, and so the Compass was employed. By the use of the Compass man began to study the starry Heavens, and as the Square primarily symbolized the Earth, the Compass began to symbolize the Heavens, the celestial canopy, the study of which has led men to think of God, and adore Him as the Supreme Architect of the Universe. In later times the Compass began to symbolize the spiritual or higher nature of man, and it is a significant fact that the circumference of a circle, which is a line without end, has become an emblem of Eternity and symbolizes Divinity; so the Compass, and the circle drawn by the Compass, both point men Heavenward and Godward.

The Masonic teaching concerning the two points of the Compass is very interesting and instructive. The novitiate in Masonry, as he kneels at this altar, and asks for Light sees the Square, which symbolizes his lower nature, he may well note the position of the Compass. As he takes another step, and asks for more Light, the position of the Compass is changed somewhat, symbolizing that his spiritual nature can, in some measure, overcome his evil tendencies. As he takes another step in Masonry, and asks for further Light, and hears the significant words, "and God said let there be Light, and there was Light," he sees the Compass in new light; and for the first time he sees the meaning, thus unmistakably alluding to the sacred and eternal truth that as the Heavens are higher than the Earth, so the spiritual is higher than the material, and the spiritual in man must have its proper place, and should be above his lower nature, and dominate all his thoughts and actions. That eminent Philosopher, Edmund Burke, once said, "It is ordained that men of intemperate passions cannot be free. Their passions forge the chains which bind them, and make them slaves." Burke was right. Masonry, through the beautiful symbolism of the Compass, tells us how we can be free men, by permitting the spiritual within us to overcome our evil tendencies, and dominate all our thoughts and actions. Brethren, sometimes in the silent quiet hour, as we think of this conflict between our lower and higher natures, we sometimes say in the words of another, "Show me the way and let me bravely climb to where all conflicts with the flesh shall cease. Show me that way. Show me the way up to a higher plane where my body shall be servant of my Soul. Show me that way."

Brethren, if that prayer expresses desire of our hearts, let us take heed to the beautiful teachings of the Compass, which silently and persistently tells each one of us,

"You should not in the valley stay

While the great horizons stretch away

The very cliffs that wall you round

Are ladders up to higher ground.

And Heaven draws near as you ascend,

The Breeze invites, the Stars befriend.

All things are beckoning to the Best,

Then climb toward God and find sweet Rest."

Treating Kids with Asthma (5) by The U.S. Food and Drug Administration

1 1

FDA has approved many treatments to help children with asthma lead active lives. Most asthma medicines are inhaled, either (2) through a mask with very young children, or through (3) a small device called an inhaler. For inhalers, doctors might also prescribe (4) a device called a spacer. The spacer attaches to the inhaler to make sure that the right dose of medicine gets into the child’s lungs. “Rescue” medications treat severe symptoms, while “controller” medicines prevent or lessen symptoms. In addition, health care providers might recommend the use of (5) a peak flow meter to monitor how well a child’s treatment is working. Health care professionals will also provide (6) an asthma action plan. No matter what the medication or device, it is important for parents and children to follow the instructions and to contact their doctor’s office or pharmacy with any questions.

This sculpture by New York artist Dennis Oppenheim was rejected by Stanford University, his alma mater, and subsequently purchased by a Vancouver foundation who erected it in Harbour Green Park in downtown Vancouver. Controversy followed the upside-down church and the Vancouver Public Parks Committee voted to remove it. Calgary's Glenbow Museum jumped at the opportunity to display it and here it seems to have found a home.

4D Man (Universal International, 1959). Lobby Card(11" X 14"). by Morbius19

Starring Robert Lansing, Lee Meriwether, James Congdon, Robert Strauss, Edgar Stehli, Patty Duke, Guy Raymond, and Chic James. Directed by Irvin S. Yeaworth Jr..

James Congdon plays While a bit obscure, 4D Man (4D for short) is more of a low A-grade movie than a B-movie. For one thing, it's shot in color. It has some A-grade actors, and some cleanly done optical special effects. As in many sci-fi films, the technology isn't the star, but a plot device to propel a larger human drama. In this case, it gives the main character a special power. How he handles (or mishandles) that power is the meat of the tale.

Synopsis

Tony Nelson is talented scientist who is obsessed with his research, to the point of having a hard time keeping a job. He is trying repeat an earlier fluke success at getting one material to pass through another. (a pencil through steel) He travels to see his brother, Scott Nelson (Robert Lansing). Scott heads up a research lab trying to make a metal stronger than steel -- Cargonite. Scott convinces Tony to accept a job at his lab, but this only complicates the social scene. Scott was about to propose to co-worker-scientist Linda. Instead, Linda falls in love with Tony. Frustrated at all this, Scott goes to the lab late one night and gets into Tony's secret apparatus. He manages to get it to work. His hand passes through the steel. Meanwhile, another lab scientist, Roy, has stolen Tony's notes and is trying to sell the facility's director on the idea, so he can be a chief scientist himself. When Scott and Tony re-try the experiment in the lab, it works, even though the equipment wasn't working. Scott has "the power" all by himself. He tells Tony that he doesn't want anyone to know just yet. A newspaper headline tells of a bank robbery. The next morning, Scott sees that he's aged noticeably. Passing through matter ages him. He rushes to a friend's apartment for help, but when he touches the friend on the shoulder, the friend drops dead, his body aging to a gray shriveled corpse. Scott, however, was young again. His special power also saps life from others. He hides the amplifier so no one else can share his power. Things quickly unravel. Scott confronts his credit-stealing boss and saps him. Scott tries to find solace in a bar, with a floosie, but kills her with a kiss. The police know there's a killer on the loose. Tony tells the police all about it. The police cannot stop Scott, however. He shifts through walls, touches (and kills) policemen, and even a hail of bullets cannot stop him. He just shifts himself and the bullets pass through him. Scott finds out that Tony is trying to build another amplifier, so returns to the lab. Tony, Linda and the police try to kill Scott by turning on the reactor while he's inside it. (this is where Scott hid the amplifier) This fails because he is invincible when shifted. Everyone but Linda flees. Scott tries to talk her into running away with him. While in an embrace, she shoots him with the gun the detective left behind. Unshifted Scott is mortally wounded, but defiantly shouts his invincibility. To prove it, he throws himself into the Carbonite reactor, slowly disappearing into it's walls. The End (?)

The premise and human-interest angle are interesting and well done. The A-level actors do a good job making their characters believable. Robert Lansing does an excellent job with Dr. Scott Nelson -- both his frustrated awkward "before" self and the tormented-yet-maniacal "after" self. Given how many later movies (or TV shows) would take up the idea of people being able to pass through walls, etc., it's fun to see an early version.

This movie isn't an allegory of the Cold War. There is an oblique connection to the dangers-of-science sub-genre. A background element of the Cold War years, is the research lab working on improved materials for the military. Nelson's work isn't with any nuclear weaponry, but how it goes dreadfully is still an understated cautionary tale about how even innocent research can create a killer.

The quasi-science behind the premise, is that Scott can (at will) shift the "time" of his body relative to objects, permitting him to pass through them. The more he does this, the faster it ages him. While fanciful, this has a plausibility. The portrayal of "time" as a life force which he can then absorb from others has no plausibility, but it makes for a good plot device.

An interesting plot device is how Scott Nelson must drain the life from people in order reverse his own rapid aging. He does this by simply "touching" (merging) with them. The trope of the living sacrificed to prolong another's life, is not unique. It got (and gets) used in low-B movies like She Demons ('58) in which a mad scientist extracts hormones from young women (turning them into ugly demons) in order to keep his sick wife alive. In 4D, however, the "monster" drains life from them by a mere touch. This is a fascinating preview of the Wraith in the Stargate TV series (2005) -- race of beings who must "feed" on living humans in order to survive. The idea still has legs.

Another plot aspect which is not unique to 4D is how the man who acquires some amazing power can't handle it. For the sci-fi world, this appeared in H.G. Wells' novel "The Invisible Man." His special feature tempted him into tyranny. Once a man feels immune to the hand of justice, he commits crimes with impunity. Scott Nelson is no different in 4D. We see his morality drop away and his total human selfishness take control. He gets professional revenge on his credit-stealing boss. He robs a bank and tries to induce LInda to run away with him. At the end, he shouts, "I'm invincible! Nothing can hurt me!" with a well acted mixture of defiance, denial (he'd just been shot) and pleading. An interesting little human psych study of how man might behave if he no longer fears punishment.

An intriguing little twist amid the plot was how Scott's power was not totally under his control. By force of will, he could "turn on" his time-shift to pass through walls, but when he stopped willing it, objects were solid to him. At one point, he's trying to grab the door knob to a bar, but keeps passing his hand through it. At that moment, he wanted to be "normal" but his power was not so completely under his control. A little while later, when he wanted some companionship and kissed the B-girl, she screams in pain and turns into an old woman, then dies. Scott was becoming a sort of King Midas who ruins everything he touches. This adds a degree of pity to the character. With the "cool" power, he could never be normal again.

4D's producer, Jack Harris, and director, Irvin Yeaworth brought us The Blob in late 1958. 4D has some family resemblance. Color, big-name stars, and brassy jazz score. 4D and The Blob may have been shot together in '57. Young Patty Duke plays a bit part of a landlady's daughter, but she looks maybe ten years old -- noticeably younger than she was in 1959. Universal may have intended to release The Blob and 4D Man together, but opted to spread out the releases for better revenue.

The score in 4D is heavy-handed brass jazz band fodder. Such jazz was pretty typical stuff of 50s movies which held the Rat Pack and Las Vegas show scene as the pinnacle of cool. The score of 4D seems like a cross between a 007-wanabe movie and the Pink Panther -- but without any of Mancini's style. Given the rather dark story line, the loudly perky jazz seems out of place. Instead of enhancing the story, it intrudes, like someone talking loudly in the theater while you try to watch the flick. Unless the viewer is a fan of such brassy nightclub jazz, it's more likely to be annoying than admired.

Bottom line? 4D is worth the time. It's a modern Midas tale reasonably well done. The science is weak or a tough stretch, but the story can be enjoyed anyway.
