Latest EPOXI Stories
GREENBELT, Md., May 26 /PRNewswire-USNewswire/ -- NASA-sponsored scientists looking back at Earth with the Deep Impact/EPOXI mission have developed a method to indicate whether Earth-like alien (extrasolar) worlds have oceans.
Since the early 1990s astronomers have discovered more than 300 planets orbiting stars other than our sun, nearly all of them gas giants like Jupiter.
NASA has successfully tested the first deep space communications network modeled on the Internet.
NASA's Deep Impact spacecraft has created a video of the moon transiting (passing in front of) Earth as seen from the spacecraft's point of view 50 million kilometers (31 million miles) away. Scientists are using the video to develop techniques to study alien worlds.
NASA's Deep Impact spacecraft is aiming its largest telescope at five stars in a search for alien (exosolar) planets as it enters its extended mission, called Epoxi. More than 200 exosolar planets have been discovered to date.
NASA has approved the retargeting of the EPOXI mission for a flyby of comet Hartley 2 on Oct. 11, 2010. Hartley 2 was chosen as EPOXI's destination after the initial target, comet Boethin, could not be found. Scientists theorize comet Boethin may have broken up into pieces too small for detection.
A comet-busting NASA spacecraft zipped past Earth on Monday on its way to rendezvous with another comet in an extended mission that will also see it hunt for Earth-sized planets around a cluster of stars.
A former comet-slamming spacecraft will swing by Earth on New Year's Eve before starting a two-and-a-half-year journey to Comet Hartley 2. Deep Impact will first spend six months using the larger of its two telescopes to search for Earth-sized planets around five candidate stars.

The Deep Impact team realized that with the spacecraft already built and launched, extra discoveries could be made at very little cost, a bonus for an already successful mission.
