EPOXI Spacecraft Flew Through 'Snow' Storm at Comet Hartley 2
11.18.10
 
On its way past comet Hartley 2 on Nov. 4, 2010, NASA's EPOXI mission spacecraft flew through a storm of fluffy ice particles spewed out by carbon dioxide jets coming from the rough ends of the comet, and through water vapor flowing from its smooth, middle portion. The new findings show that Hartley 2 "works" quite differently than Tempel 1 or the other three comets visited by spacecraft.

Cut 1- (:09):  “When we saw the images come down, even in real time and the raw data and realized that we had a cloud of snow around the nucleus, we were astounded. “

Tim Larson - EPOXI Project Manager, JPL

Cut  1 -(:19):  “Getting to these small bodies and getting to these comets is hugely exciting for me.  And just on top of that, the incredible data that we’re finding when we fly by these and get up close and are really able to understand what they’re like and just understanding that so far that we’ve never been to any two comets that are the same. “

Jessica Sunshine – EPOXI Deputy Principle Investigator, University of Maryland

Cut 1 - (:10) “We can ask the question “What are these features that are caused by the jets” or “which is cause which is effect”  and comparing the two surfaces I think is really going to let us understand how these work. “
