It would be helpful to have a similar type of mission go to an asteroid and compare the results, ... That mission is Deep Interior. It has been proposed in the past to NASA's Discovery program, but has not been accepted.

Would we want to do the same thing to a different type of comet? I don't want to answer that question until we have analyzed the results from this comet. It depends on what picture we piece together from observing beneath this comet's surface,

The results from the current mission will be essential for developing a better understanding of the actual asteroid environment, and for making large advances in asteroid science.

The mission that they'll go on in terms of picking up, delivering critical supplies is very similar to the type of mission these particular aircraft and this particular unit will do in combat,

I'm terribly excited. We're all jumping up and down. I'm pleased that NASA hasn't given up on science altogether.

When we planned our experiment, we estimated how long it would take for the dust to fall back onto the comet, and multiplied that estimate by 4. We only had a limited time to observe because this was all happening at relative speeds of 22,000 miles per hour. To our surprise, the dust never cleared!
