Based on the Boeing C-97 cargo plane and the 377 airliner the huge "Guppy" super-transports are some of the most unique aircraft ever built. Designed to carry very large, but relatively light cargos the Guppies were built from parts of retired U.S. Air Force C-97 Stratofreighters and airline 377 Stratocruisers. The planes proved to be very useful for carrying segments of rockets and much of the Saturn rocket that powered the Apollo Program was transported in the Super Guppy. This is the second Guppy, the first "Super Guppy" built. Its parts came from at least two different aircraft. The majority of the airframe came from a former Pan American Airways airliner. However the wings, engines and forward fuselage came from one of the Air Force's experimental turbo-prop powered YC-97J aircraft, 52-2693. The Super Guppy continued in use by NASA until 1991 when it was retired in favor of a younger Super Guppy.
A dark Sun hangs in the clearing sky over a volcanic planet in this morning sea and skycape. It was taken during this week's total solar eclipse, a dramatic snapshot from along the narrow path of totality in the dark shadow of a New Moon. Earth's Indonesian isle of Ternate, North Maluku lies in the foreground. The sky is still bright near the eastern horizon though, beyond the region's flattened volcanic peaks and outside the Moon's umbral shadow. In fact, near the equator the dark lunar umbra is rushing eastward across Earth's surface at about 1,700 kilometers (1,100 miles) per hour. Shining through the thin clouds, around the Sun's silhouette is the alluring glow of the solar corona, only easily seen during totality. An inspiring sight for eclipse watchers, this solar corona is the tenuous, hot outer atmosphere of the Sun. via NASA ift.tt/1UVhhrg
An unusual celestial object called CX330 was first detected as a source of X-ray light in 2009. It has been launching “jets” of material into the gas and dust around it. via NASA ift.tt/2aqttPC

Funny the vast fortune paid by us, NASA conveniently cuts live feeds at the right time that puts them in the position of explaining something that might be hard to explain.
Better pulling the plug that ruins an otherwise boring image when something cruises past a camera that's not part of NASA'S program.
I thought NASA was about learning and exploring , at best we get panic mode sudden camera failure. I just find it funny.
This night was so serene you could see Orion rise downwards. The unusual spectacle was captured in this single-exposure image, featuring a deep sky around the famous constellation of Orion that appeared both above -- and reflected in -- a peaceful lake in the Gyirong Valley of Tibet, China. Taken last year at this time, the three belt stars of Orion can be seen lined up almost vertically above and below the Himalayan Mountains. The complex Orion Nebula can be seen to the belt stars' right, while the red-glowing circular structure surrounding Orion is Barnard's Loop. Also, the bright red star Betelgeuse is doubly visible on the image left, while bright blue Rigel appears twice on the image right. Familiar Orion is becoming increasingly visible as Winter (Summer) descends on the Northern (Southern) hemisphere. via NASA ift.tt/1Z3aHQR
This cosmic close-up looks deep inside the Soul Nebula. The dark and brooding dust clouds outlined by bright ridges of glowing gas are cataloged as IC 1871. About 25 light-years across, the telescopic field of view spans only a small part of the much larger Heart and Soul nebulae. At an estimated distance of 6,500 light-years the star-forming complex lies within the Perseus spiral arm of the Milky Way, seen in planet Earth's skies toward the constellation Cassiopeia. An example of triggered star formation, the dense star-forming clouds of IC 1871 are themselves sculpted by the intense winds and radiation of the region's massive young stars. This color image adopts a palette made popular in Hubble images of star-forming regions. via NASA go.nasa.gov/1GOahaZ
NASA image acquired November 9, 2012
In early November 2012, a wintery nor’easter followed on the heels of Hurricane Sandy. When that second storm cleared out of the region, it left behind snow stretching from New Jersey to Massachusetts. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this natural-color view of the region on November 9, 2012.
The National Weather Service’s Philadelphia / Mt. Holly (N.J.) forecast office reported that snowfall from the storm was “considerably worse than forecast for portions of northern and central New Jersey,” but less than forecast in other areas.
From the vantage point of MODIS, snowfall was the visible impact of the storm. But the areas blanketed in white were not the only ones affected by the storm. The National Weather Service also observed wind gusts up to 65 miles (105 kilometers) per hour; high waves and minor coastal flooding in New Jersey and Delaware; and 1.5 inches (4 centimeters) of rain along the New Jersey coast. Similar conditions were reported in coastal New England.
The nor’easter hit areas already struggling in the aftermath of Hurricane Sandy, including those suffering through ongoing power outages. The Associated Press reported that tens of thousands of customers in New York and New Jersey remained without electricity two weeks after Sandy’s landfall.

On the Moon, the Earth never rises -- or sets. If you were to sit on the surface of the Moon, you would see the Earth just hang in the sky. This is because the Moon always keeps the same side toward the Earth. Curiously, the featured image does picture the Earth setting over a lunar edge. This was possible because the image was taken from a spacecraft orbiting the Moon - specifically the Lunar Reconnaissance Orbiter (LRO). In fact, LRO orbits the Moon so fast that, from the spacecraft, the Earth appears to set anew about every two hours. The featured image captured one such Earthset about three months ago. By contrast, from the surface of the Earth, the Moon sets about once a day -- with the primary cause being the rotation of the Earth. LRO was launched in 2009 and, while creating a detailed three dimensional map of the Moon's surface, is also surveying the Moon for water and possible good landing spots for future astronauts. via NASA ift.tt/1Z0XPYN
This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface. via NASA ift.tt/1MpKPpM
The many spectacular colors of the Rho Ophiuchi (oh'-fee-yu-kee) clouds highlight the many processes that occur there. The blue regions shine primarily by reflected light. Blue light from the star Rho Ophiuchi and nearby stars reflects more efficiently off this portion of the nebula than red light. The Earth's daytime sky appears blue for the same reason. The red and yellow regions shine primarily because of emission from the nebula's atomic and molecular gas. Light from nearby blue stars - more energetic than the bright star Antares - knocks electrons away from the gas, which then shines when the electrons recombine with the gas. The dark brown regions are caused by dust grains - born in young stellar atmospheres - which effectively block light emitted behind them. The Rho Ophiuchi star clouds, well in front of the globular cluster M4 visible here on the upper right, are even more colorful than humans can see - the clouds emits light in every wavelength band from the radio to the gamma-ray. via NASA ift.tt/29fkX38
What's California doing in space? Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud by chance echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way's Orion Arm, only about 1,500 light-years from the California Nebula. Also known as NGC 1499, the classic emission nebula is around 100 light-years long. On the featured image, the most prominent glow of the California Nebula is the red light characteristic of hydrogen atoms recombining with long lost electrons, stripped away (ionized) by energetic starlight. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei just to the right of the nebula. A regular target for astrophotographers, the California Nebula can be spotted with a wide-field telescope under a dark sky toward the constellation of Perseus, not far from the Pleiades. via NASA ift.tt/1OfMqBf
Have you ever seen the Man on the Moon? This common question plays on the ability of humans to see pareidolia -- imagining familiar icons where they don't actually exist. The textured surface of Earth's full Moon is home to numerous identifications of iconic objects, not only in modern western culture but in world folklore throughout history. Examples, typically dependent on the Moon's perceived orientation, include the Woman in the Moon and the Rabbit in the Moon. One facial outline commonly identified as the Man in the Moon starts by imagining the two dark circular areas -- lunar maria -- here just above the Moon's center, to be the eyes. Surprisingly, there actually is a man in this Moon image -- a close look will reveal a real person -- with a telescope -- silhouetted against the Moon. This featured well-planned image was taken in mid-January in Cadalso de los Vidrios in Madrid, Spain. Do you have a favorite object that you see in the Moon? via NASA ift.tt/1QBUFZn
NASA Shuttle Bus- April 30th, 2014-
We live right outside of NASA here in Houston, They retired the 747 used to ferry the Space Shuttles after their flights. They retired the Jumbo Bus and hauled it in pieces to its final resting spot at the Space Museum on the NASA Grounds. They had to move all the pieces at night and it came right by my neighborhood last night! What an event They had everything shut down! It as quite a sight. It was stopped here for 30 minutes while utility companies moved overhead wires at an upcoming intersection, making for a great photo-op!

What are those specks in front of the Moon? They are silhouettes of the International Space Station (ISS). Using careful planning and split-second timing, a meticulous lunar photographer captured ten images of the ISS passing in front of last month's full moon. But this wasn't just any full moon -- this was the first of the three consecutive 2016 supermoons. A supermoon is a full moon that appears a few percent larger and brighter than most other full moons. The featured image sequence was captured near Dallas, Texas. Occurring today is the second supermoon of this series, a full moon that is the biggest and brightest not only of the year, but of any year since 1948. To see today's super-supermoon yourself, just go outside at night and look up. The third supermoon of this year's series will occur in mid-December. via NASA ift.tt/2g7kRCM

I am particularly excited that my Model X config (see below) will be shuttling the astronauts to the pad. I always thought it looked like a spaceship in white — channeling a Space 1999 crew capsule with a Star Wars stormtrooper gleam.
"The all-electric SUV has become the official transport vehicle for SpaceX crew missions and a far departure from the Airstream vans that NASA has used for decades. The Crew Dragon Demo-2 mission will finish the validation process for human-rated spaceflight operations that utilize SpaceX craft. The upcoming launch, slated for May 27, will mark NASA’s first crewed launch in nearly a decade. Both astronauts will make its way to the International Space Station inside the SpaceX Crew Dragon spacecraft and remain in space for over a month before coming back to Earth." — Teslarati
And tweeted by the NASA Administrator: "Here’s some Tesla news that everyone should love. Check out the Model X that will carry Astro_Behnken and Astro_Doug to the launchpad for the Demo-2 mission! #LaunchAmerica"

A 1,000-foot convoy carrying the nonprofit Space Center Houston’s historic shuttle carrier aircraft will journey home on an eight-mile trek through the bay area during the nights of April 28-29, arriving the morning of April 30. Roads will close so workers can dismantle streetlights, signs and utility poles as the convoy approaches.
The portion of Highway 3 (Old Galveston Road) between its intersections with Scarsdale and NASA Parkway will close 9 p.m. to 4:30 a.m. Monday, April 28. Then on Tuesday, April 29, NASA Parkway from Highway 3 to Saturn Lane will close from 9 p.m. to 4:30 a.m. (See Route Map)
Thanks to extensive pre-planning efforts, no utilities are expected to be interrupted. The convoy will travel at night for the safety of our neighbors and the workers involved in this complex transfer, as well as to minimize the impact on local residents, the traveling public and businesses.
The project to disassemble and safely transport the massive airplane was done in partnership with 30 private, public, and government organizations, many of whom did the work for little or no charge.
Moving at walking speed, the convoy will carry the disassembled Boeing 747 sections on six different trailers from Ellington Field. The largest section moving intact is the fuselage, measuring 25 feet wide, 35 feet high and over 190 feet long, which will travel on a Goldhofer multi-wheeled, self-propelled trailer.
What's that in the sky? Although there was much to see in this spectacular panorama taken during the early morning hours of a day in late September, the brightest object in the sky was clearly the planet Venus. In the featured image, Venus was captured actually through a natural rock bridge, itself picturesque, in Spitzkoppe, Namibia. The planet, on the left of the opening, was complemented by a silhouette of the astrophotographer on the right. Above and beyond the rock bridge were many famous icons of a dark night sky, including, from left to right, the Pleiades star cluster, the Orion Nebula, the bright star Sirius, and the Large and Small Magellanic Clouds. This week, Venus remains visible to the east in the pre-dawn sky, being complemented by Mars, which is angularly quite close. via NASA ift.tt/1MvlQQN
Recorded in 2014 April, this total lunar eclipse sequence looks south down icy Waterton Lake from the Waterton Lakes National Park in Alberta, Canada, planet Earth. The most distant horizon includes peaks in Glacier National Park, USA. An exposure every 10 minutes captured the Moon's position and eclipse phase, as it arced, left to right, above the rugged skyline and Waterton town lights. In fact, the sequence effectively measures the roughly 80 minute duration of the total phase of the eclipse. Around 270 BC, the Greek astronomer Aristarchus also measured the duration of lunar eclipses - though probably without the benefit of digital clocks and cameras. Still, using geometry, he devised a simple and impressively accurate way to calculate the Moon's distance, in terms of the radius of planet Earth, from the eclipse duration. This modern eclipse sequence also tracks the successive positions of Mars, above and right of the Moon, bright star Spica next to the reddened lunar disk, and Saturn to the left and below. via NASA ift.tt/1NWb8qX
In one of the brightest parts of Milky Way lies a nebula where some of the oddest things occur. NGC 3372, known as the Great Nebula in Carina, is home to massive stars and changing nebulas. The Keyhole Nebula (NGC 3324), the bright structure just above the image center, houses several of these massive stars and has itself changed its appearance. The entire Carina Nebula spans over 300 light years and lies about 7,500 light-years away in the constellation of Carina. Eta Carinae, the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. Eta Carinae is the brightest star near the image center, just left of the Keyhole Nebula. While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Carina Nebula has been a veritable supernova factory. via NASA ift.tt/25mesUK
What are those colorful arcs in the sky? Like rainbows that are caused by rain, arcs of sunlight broken up into component colors can also result when ice crystals floating in Earth's atmosphere act together as a gigantic prism. The top color arc is more typical as it is part of the 22 degree halo surrounding the Sun when hexagonal ice crystals refract sunlight between two of the six sides. More unusual, though, is the bottom color arc. Sometimes called a fire rainbow, this circumhorizon arc is also created by ice, not fire nor even rain. Here, a series of horizontal, thin, flat ice crystals in high cirrus clouds refract sunlight between the top and bottom faces toward the observer. These arcs only occur when the Sun is higher than 58 degrees above the horizon. The featured sky occurred to the northwest in the early afternoon last month over a street Diagonal of La Plata City, Buenos Aires, Argentina. via NASA ift.tt/1J92mRy
Check this out from NASA -- Why would these clouds multi-colored? A relatively rare phenomenon in clouds known as iridescence can bring up unusual colors vividly or even a whole spectrum of colors simultaneously. These polar stratospheric clouds clouds, also known as nacreous and mother-of-pearl clouds, are formed of small water droplets of nearly uniform size. When the Sun is in the right position and, typically, hidden from direct view, these thin clouds can be seen significantly diffracting sunlight in a nearly coherent manner, with different colors being deflected by different amounts. Therefore, different colors will come to the observer from slightly different directions. Many clouds start with uniform regions that could show iridescence but quickly become too thick, too mixed, or too angularly far from the Sun to exhibit striking colors. The featured image and an accompanying video were taken late last year over Ostersund, Sweden. (ift.tt/36QLfXw)
Giant elliptical galaxy M60 and spiral galaxy NGC 4647 do look like an odd couple in this sharp cosmic portrait from the Hubble Space Telescope. But they are found in a region of space where galaxies tend to gather, on the eastern side of the nearby Virgo Galaxy Cluster. About 54 million light-years distant, bright M60's simpler egg-like shape is created by its randomly swarming older stars, while NGC 4647's young blue stars, gas and dust are organized into winding arms rotating in a flattened disk. Spiral NGC 4647 is estimated to be more distant than M60, some 63 million light-years away. Also known as Arp 116, the pair of galaxies may be on the verge of a significant gravitational encounter, though. M60 (aka NGC 4649) is about 120,000 light-years across. The smaller NGC 4647 spans around 90,000 light-years, about the size of our own Milky Way. via NASA ift.tt/1ZVsRBG
Scan of a postcard issued by NASA,. Reverse not dated though states from "A series of 6 from authentic NASA transparencies".
The Tarantula Nebula is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud, about 180 thousand light-years away. The largest, most violent star forming region known in the whole Local Group of galaxies, the cosmic arachnid sprawls across this spectacular composite view constructed with space- and ground-based image data. Within the Tarantula (NGC 2070), intense radiation, stellar winds and supernova shocks from the central young cluster of massive stars, cataloged as R136, energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star forming regions with young star clusters, filaments, and blown-out bubble-shaped clouds In fact, the frame includes the site of the closest supernova in modern times, SN 1987A, at the lower right. The rich field of view spans about 1 degree or 2 full moons, in the southern constellation Dorado. But were the Tarantula Nebula closer, say 1,500 light-years distant like the local star forming Orion Nebula, it would take up half the sky. via NASA ift.tt/1XPFyyp

What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA’s James Webb Space Telescope in Chamber A at NASA’s Johnson Space Center in Houston. The photo was used to verify the line of sight (or path light will travel) for the testing configuration.
During Webb’s extensive cryogenic testing, engineers checked the alignment of all the telescope optics and demonstrated the individual primary mirror segments can be properly aligned to each other and to the rest of the system. This all occurred in test conditions that simulated the space environment where Webb will operate, and where it will collect data of never-before-observed portions of the universe. Verifying the optics as a system is a very important step that will ensure the telescope will work correctly in space.

GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA). The Core Observatory will link data from a constellation of current and planned satellites to produce next-generation global measurements of rainfall and snowfall from space.
On Feb. 11, the Core Observatory was moved into the spacecraft fairing assembly building and into the Encapsulation Hall. Final inspections and preparations were completed for the installation into the fairing, which began on Feb 13. The fairing is the part of the rocket that will contain the spacecraft at the top of the H-IIA rocket.
The encapsulation process for the H-IIA is very different than for most U.S. rockets. For U.S. rockets, the fairing is usually in two pieces that close around the payload like a clamshell. To install the GPM Core Observatory into the fairing of the H-IIA rocket, first the Core Observatory and the Payload Attach Fitting (PAF) are set up in scaffolding in the Encapsulation Hall. Then, the fairing is lifted above and lowered onto the fitting. When only a few feet remain above the final position, stanchions support the fairing while technicians go inside to complete the electrical connections. When this is completed, they remove the stanchions and lower the fairing to its final position, where it is bolted in place.
The GPM mission is the first coordinated international satellite network to provide near real-time observations of rain and snow every three hours anywhere on the globe. The GPM Core Observatory anchors this network by providing observations on all types of precipitation. The observatory's data acts as the measuring stick by which partner observations can be combined into a unified data set. The data will be used by scientists to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking.

A waning crescent moon, early morning twilight, and Al Hamra's city lights on the horizon can't hide the central Milky Way in this skyscape from planet Earth. Captured in a single exposure, the dreamlike scene looks southward across the region's grand canyon from Jabal Shams (Sun Mountain), near the highest peak in Oman, on the Arabian Peninsula. Mist, moonlight, and shadows still play along the steep canyon walls. Dark rifts along the luminous band of the Milky Way are the galaxy's cosmic dust clouds. Typically hundreds of light-years distant, they obscure starlight along the galactic plane, viewed edge-on from the Solar System's perspective. via NASA ift.tt/1SDb1W1
What's that inside the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. The nebula glows brightly in red light emitted by its most prominent element: hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. At the top right is the companion Fishhead Nebula. via NASA ift.tt/1jNXN9y
The Horsehead Nebula is one of the most famous nebulae on the sky. It is visible as the dark indentation to the red emission nebula in the center of the above photograph. The horse-head feature is dark because it is really an opaque dust cloud that lies in front of the bright red emission nebula. Like clouds in Earth's atmosphere, this cosmic cloud has assumed a recognizable shape by chance. After many thousands of years, the internal motions of the cloud will surely alter its appearance. The emission nebula's red color is caused by electrons recombining with protons to form hydrogen atoms. On the image left is the Flame Nebula, an orange-tinged nebula that also contains filaments of dark dust. Just to the lower left of the Horsehead nebula featured picture is a blueish reflection nebulae that preferentially reflects the blue light from nearby stars. via NASA ift.tt/1lPuhBd
I put this video together in memory of my father. I remember watching the Apollo missions on our black and white tv as a child and was amazed by the thought of space travel and the idea on landing on the moon.
Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1/3 degree wide field of view spans over 30 light-years. The sharp composite, color image, highlights faint details of the region's gas and dust clouds against a backdrop of central Milky Way stars. Stellar winds and energetic light from hot, massive stars formed from M17 stock of cosmic gas and dust have slowly carved away at the remaining interstellar material producing the cavernous appearance and undulating shapes. M17 is also known as the Omega Nebula or the Swan Nebula. via NASA ift.tt/1OKwXfd
