Re the tiles' heat capacity and tolerance; there was a very good article in
National Geographic circa +- 79-81 or so I think. I recall it because of a
photo of a guy holding one in his bare hand which had been heated to cherry

materials have been developed since the shuttle tile system was

Also, does anyone know the heat tolerance of the tiles on the shuttl

As my title suggests, would it be feasible to build a separate probe moving just ahead of the Icepick bot, designed solely to melt through the Europan ice? My thinking here is, *instead of* burdening Icepick with *both* science instrumentation and heating equipment, why not have a bot lead the wa

If I understand JHB correctly, he assumes that the the melted water will be
in hydrostatic equilibrium with the surrounding ice.
This is true if:
1) the melt water and ice density are equal
