No discussion of re-entry survival
[edit]The crucial subject of impact survival concerns re-entry into a host planet, as expunded on in the opening paragraph:
- "Impact survival is a theory that life, usually in the form of microbial bacteria, can survive under the extreme conditions they are exposed to during a major impact event, such as a meteorite striking the surface of a planet."
Yet, all of the ensuing article (so far) is only about surviving escape velocity:
- "For small organisms to leave a planet's orbit, escape velocity must be reached, which is dependent upon the mass of the planet."
and
- "Recent experiments have found organisms that can survive both the acceleration and jerk involved in reaching escape velocity."
The chief danger to potential panspermic life is not vacuum, acceleration or even cosmic rays. Panspermia advocates need to prove that life can survive the extreme temperatures of re-entry.
Perhaps we can find some successful experiments relative to this question? Kortoso (talk) 17:00, 6 September 2013 (UTC)
