NASA Announces Another Comet Mission for DEEP IMPACT
NASA announced today that it has accepted the University of Maryland proposal to send the Deep Impact spacecraft on an extended mission to get a close-up look at Comet Boethin.
The University of Maryland-led team that produced the spectacular Deep Impact mission, which smashed an impactor into Comet Tempel 1 in July, 2005, hopes new information gathered from Comet Boethin will help coalesce the vast array of new cometary information into solid ideas about the nature of comets, how they formed and evolved and if they have played a role in the emergence of life on Earth.
“As we try to interpret the larger meaning for all comets of our results from Deep Impact at Tempel 1, we have realized more and more how important is the variation from comet to comet,” said Deep Impact leader and University of Maryland astronomer Michael A'Hearn.
“Deep Impact's flyby spacecraft and payload are still healthy. We propose to direct the spacecraft for a flyby of Comet Boethin in December, 2008, to investigate whether the results found at Comet Tempel 1 are unique or are also found on other comets,” said A’Hearn.
"This mission is a very cost effective way to provide new results that can be directly compared to the landmark Deep Impact findings as well as with the results of Deep Space 1 and Stardust and the earlier results from the numerous missions to Comet Halley.”
