Comet Tempel Flyby

The Stardust-NExT probe flew to within 112 miles of Comet Tempel I on February 14, taking a series of photos of the comet. Comet Tempel had previously been visited by a NASA spacecraft in 2005, when Deep Impact collided with the comet. This is the first time a comet has been revisited after a complete orbit. Photos have shown that erosion has changed the face of the comet, but the impact crater left by Deep Impact appears to have partially healed itself.

Second Life for Shuttles

United Space Alliance has proposed the Commercial Space Transportation Service, which would keep two orbiters in the space shuttle fleet, Atlantis and Endeavour active and flying two missions each year from 2013 through 2017 while the United States gets a new generation of manned launch vehicles ready. NASA has not officially commented on the USA plan and is publicly stating that the current plans to send the three orbiters to museums.

Kepler Finds New Planets

Results from the first four months of observation from the Kepler space observatory have been released indicating the discovery of more than 1200 potential planets, including 165 Jupiter-class planets, 662 Neptune-class planets, 288 superEarth class planets, and 68 Earth-class planets, 54 of which are considered to be in the habitable zone. Kepler has been searching a portion of the sky that includes the constellation Cygnus and Lyra and looked at 156,000 stars during the period covered by the released data.

Voyager Nears the Heliopause

The Voyager 1 space probe has entered the Heliosheath, an area where the solar wind drops to zero velocity. The heliosheath is the final region of our solar system and scientists believe that Voyager is within five years of crossing the heliopause, the edge of the solar system, and entering interstellar space. Scientists had previously thought Voyager was preparing to make the jump to interstellar space in 2005, but since the probe is in unknown territory, it is still sending back data which is changing astronomers’ models of the solar system. Launched in 1977, Voyager completed its mission to study the Jovian planets in 1989 when it passed Neptune. It is now located about 17.4 billion miles from Earth and is still sending back data.

Spaceship Comes Home

NASA’s X-37B, an unmanned spacecraft launched via rocket in April, landed at Vandenberg Air Force Base after a seven month long mission that NASA says was used as a test for the spacecraft itself. According to officials, the flight was to test guidance, navigation, control, thermal protection, and autonomous operation in orbit, re-entry, and landing. NASA plans to launch the craft again some time in 2011
