Tuesday, November 13, 2012 I have had a think about what a space
probe would find at the surface of a comet (nucleus). I am
thinking it would be made up of a biosynthetic petroleum gel.
Long chain chiral - similar in chemical consistency to tar. The
function of this skin of at least several metres would be to
absorb the sun's heat (being black) and of absorbing meteoric
impact. The functional interior organs of the comet need to be
protected, and an energy source is required. Posted by Marco at
