The Strategic Defense Initiative (SDI), commonly called Star Wars after one of the popular science fantasy movies of the time, was proposed by U.S. President Ronald Reagan on March 23, 1983 to use ground-based and space-based systems to protect the United States from attack by strategic nuclear ballistic missiles. The initiative focused on strategic defense rather than the prior strategic offense doctrine of mutual assured destruction (MAD).
Though it was never fully developed or deployed, the research and technologies of SDI paved the way for some anti-ballistic missile systems of today. The Strategic Defense Initiative Organization (SDIO) was set up in 1984 within the United States Department of Defense to the Strategic Defense Initiative. Under the administration of President Bill Clinton in 1993, its name was changed to the Ballistic Missile Defense Organization (BMDO) and its emphasis was shifted from national missile defense to theater missile defense; from global to regional coverage. BMDO was later renamed to the Missile Defense Agency. This article covers defense efforts under the SDIO.
In 1984, the Strategic Defense Initiative Organization (SDIO) was established to oversee the program, which was headed by Lt. General James Alan Abrahamson, USAF, a past Director of the NASA Space Shuttle program. Research and development initiated by the SDIO created significant technological advances in computer systems, component miniaturization, sensors and missile systems that form the basis for current systems.
Initially, the program focused on large scale systems designed to defeat a Soviet offensive strike. However, as the threat diminished, the program shifted towards smaller systems designed to defeat limited or accidental launches.
By 1987, the SDIO developed a national missile defense concept called the Strategic Defense System Phase I Architecture. This concept consisted of ground and space based sensors and weapons, as well as a central battle management system. The ground-based systems operational today trace their roots back to this concept.
In his 1991 State of the Union Address George H. W. Bush shifted the focus of SDI from defense of North America against large scale strikes to a system focusing on theater missile defense called Global Protection Against Limited Strikes (GPALS).
In 1993, the Clinton administration, further shifted the focus to ground-based interceptor missiles and theater scale systems, forming the Ballistic Missile Defense Organization (BMDO) and closing the SDIO. Ballistic missile defense has been revived by the George W. Bush administration as the National Missile Defense and Ground-based Midcourse Defense.

Description: Alfred J. Eggers served as NASA's Assistant Administrator for Policy from January 1968 through March 1971. After that he accepted a position as Assistant Director for Research Applications at the National Science Foundation.
Dr. Eggers came to the NACA (National Advisory Committee for Aeronautics) Ames Aeronautical Laboratory in 1944 from the Navy's V- 12 college program. In 1954, he was made Division Chief of the Vehicle Environment Division. This Division was comprised of a physics branch, an entry simulation branch, a structural dynamics branch, the 3.5 foot hypersonic wind tunnel branch and the hypervelocity ballistic range branch. In 1958, Dr. Eggers headed the Manned Satellite Team which was to consider design problems and propose a practical system for a satellite while recommending a suitable research program. This ultimately lead to Ames developing and managing the highly successful Pioneer program. Dr. Eggers specialized in hypersonic and spaceflight research including the development of new wind tunnel and ballistic range facilities. In May of 1964, Dr. Eggers was appointed Deputy Associate Administrator for Advanced Research and Technology.

Piers Sellers has a laugh as Mrs. Schnetzler
tells a story of her husband Charlie Schnetzler.
NASA Astronaut Piers Sellers will honor former Goddard scientist, the late Charlie Schnetzler, by presenting his wife and family with the Australasian tektites collected by her husband during his search for the source crater and flown in orbit by Astronaut Sellers.
Tektites are pieces of melted rock blasted into space by hypervelocity impact events, such as those made when near earth objects (NEO’s) collide with Earth. These objects return to the Earth’s surface as recondensed rock “glass.”
This event is symbolic of the great scientific impact Mr. Schnetzler had on Earth, planetary sciences, and the importance of continued human spaceflight.

The lunar impact crater Copernicus is shown in this image. Copernicus is about 58 miles (92 km) in diameter and 2.4 miles (3.8 km) deep. The crater was formed almost 1 billion years ago when a large asteroid struck the lunar surface traveling at a hypervelocity greater than 7 miles per second (11 km per second). The violent impact released much more energy than the largest man-made thermonuclear bomb. The energy released dug the 58 mile (92 km) diameter crater, formed the central mountain peaks, and lifted the terraced crater walls above up to 2.4 miles (3.8 km) above surrounding lunar surface. The heat generated in the catastrophic blast melted rock the produced the flow patterns on the exterior walls of Copernicus that have been frozen in time.
The blast associated with the creation of Copernicus spread material radially outward on the lunar surface up to 500 miles (810 km) from the crater. If a large asteroid like the one that produced Copernicus struck the Earth today, the damage would be catastrophic and would be spread over a large region of the Earth's surface. A direct hit by a large asteroid on a major city would eliminate that city as well producing an area of destruction that would spread hundreds of miles in all direction around the impact crater.
A Celestron C5 SCT operating at f/23 was used with a Canon T2i camera operating in 640x480 crop Movie Mode to capture the data for this image. About 3600 movie frames were used to build the final image using the Lucky Imaging technique. Registax 5 was used to combine the best frames and to sharpen the resolution of the final image.

About Lonar Crater
Lonar has been formed naturally due to a hypervelocity meteorite impact and it ranks third in largest salt water lake in the world. It is a huge and naturally formed salt lake. It was discovered by a British officer J.E. Alexander in 1823.
The Lonar crater is only one of it's kind in the word that has been formed from Basaltic rock. The crater of the lake is 7 times saltier than the sea water. Lonar lake is situated in Buldana district on the border of Lonar village 90 kms away from Buldana city. The meteorite which formed the lake hit the earth 50,000 years back forming the lake 150 metres deep with 1.8 kms in diameter.
Lonar crater has almost perfectly circular shape with a circumference of 6 kms at the top and 4 kms at the base of the lake. According to mythology, Lonar acquired it's name from lonasura, a demon who was killed by lord Vishnu. On the way to the base of the crater is Daitya sudan temple, which represents the richness of Hoysala style.
The nearest airport is Aurangabad(141 Kms) and the nearest railway station is Malkapur (135Kms).
We wanted to see how deep various rounds would penetrate a two-inch thick phone book. While not horribly scientific, we tried a few types of rounds (clockwise from upper left):

"Pica Glass" is an anomalous natural glass that occurs in areas of Chile's Atacama Desert in South America. Nickel-bearing minerals are present, as are minerals that form under very high temperature conditions. The glass is interpreted as having formed by and being contaminated by a bolide impact (airburst). Isotopic dating indicates a Late Pleistocene age, about 12,000 years ago. Some researchers assert that no nickel is present in Pica Glass and conclude the glass formed by low-temperature surface fires.

Hypervelocity Stars near high than Speed of Light fast enough to escape the gravitational grasp of the Milky Way galaxy. The idea that stars live in galaxies has since the 1920’s. It took bu today technology international team has discovered a surprising new class of “hypervelocity stars” you are interested in escaping from Earth or others planet; in later now you will consider the escape velocity from stars,all time high than galaxies, and even black holes,about three times faster than a typical velocity.
