Re: Europa's ice thickness

[Robert Crawley]

Just wondering if ice would become more dense at said meotor impact site, as opposed to a "fresh" one? And out of curiousity, what is the microgravity on the ISS in relation to Europa? Could it be worth an experiment to make ice with the same composistions as expected on Europa in low earth orbit, then play with it?   Robert Crawley Elite Precision Fabricators, Inc.

It may be a sidestep on the march to the sea, but taking extra time and effort to protect against the radiation experienced by surface machinery would likely pay off, particularly considering that this is a mission which would require at least 2 years time to complete. -- JH Byrne
