|In this installment of NASA Now, you’ll meet spacecraft pilot and engineer Steven Wissler, who talks about the challenges of flying a spacecraft remotely from Earth and the excitement of being part of a team that discovers something new about comets.
The program focus is on the EPOXI flyby spacecraft. EPOXI is a recycling of the Deep Impact spacecraft, whose probe intentionally collided with comet Tempel 1 on July 4, 2005, revealing, for the first time, the inner material of a comet. Deep Impact returned to an Earth orbit where it was reprogrammed to rendezvous with a second comet, Hartley 2. After reprogramming, the spacecraft received a gravity assist from Earth and began its second life, dubbed EPOXI. The spacecraft incorporated the same trio of instruments used during the Deep Impact mission: two telescopes with digital imagers to record the encounter, and an infrared spectrometer.
