...which I decided to attend literally at the last possible minute, which is why I didn't alert you guys in advance. Very interesting -- both the discussions about the likely design of the mission (and how to retrieve it from cancellation), and many of the actual science presentations (which aren't on the Web yet, although they probably soon will be). I'll give you some more information tomorrow -- although I can't resist telling Alex that Tom Spilker's subgroup took my ideas about a Europa penetrator, and the printed information I gave them on the subject, seriously enough to recommend making further inquiries to NASA HQ on it. (And without my browbeating them, either. Nyaah.) The case for it, however, is still extremely far from certain.
As I say, more tomorrow. |

I make a 2km drop to Europa a 72 m/sec impact after a fall of 52 seconds.
I'm guessing you want the forebody at least 2m down, and thus that's, I THINK - 124G. The afterbody, you want it to stop very quickly, perhaps 25 cm, thus that's, again, if my maths is right - approx 1000G Doug |
