NASA's Deep Impact spacecraft is spinning out of control

NASA's Deep Impact spacecraft is in deep trouble. The craft, famous for blasting a projectile into the Comet Tempel 1 in 2005, lost contact with Earth sometime between 11 August and 14 August. Recent commands to put the craft in hibernation, or safe mode, were unsuccessful, and Deep Impact is now spinning out of control, says principal investigator Michael AHearn of the University of Maryland in College Park. The mission was renamed Epoxi when it was extended to observe comets and stars with transiting exoplanets.

Deep Impact Spacecraft Completes Rocket Burn

The Deep Impact spacecraft completed a firing of its onboard rocket motors. The manoeuvre began at 20:00 UT, [4th October, 2012] lasted 71 seconds, and changed its velocity by 2 metres per second. The rocket burn was performed to keep the venerable comet hunter's options open for yet another exploration of a solar system small body, this time a possible future visit to a small near-Earth asteroid called 2002 GT.

The EPOXI spacecraft made a close flyby (36860 km) to the Earth at 22:03 UTC, 27th June, 2010.
The closest approach was over the Southern Atlantic Ocean.

NASA's Deep Impact Spacecraft Eyes the Future

NASA's Deep Impact spacecraft completed a 140-second firing of its onboard rocket motors on Thursday, Nov. 24. The rocket burn was performed to keep the venerable comet hunter's options open for yet another exploration of a solar system small body.

Science Paper Details NASA Epoxi Flyby of Hyper Comet

Comet Hartley 2's hyperactive state, as studied by NASA's EPOXI mission, is detailed in a new paper published in this week's issue of the journal Science.
After visiting a comet and imaging distant stars for hints of extrasolar planets, you could say the spacecraft used for EPOXI had seen its fair share of celestial wonders. But after about 5.1 billion kilometres of deep space travel, one final wonder awaited the mission's project and science teams. On Nov. 4, 2010, the EPOXI mission spacecraft flew past a weird little comet called Hartley 2.
