SUMMARY

The discussion centers on the properties of ancient mid-latitude Martian ice, specifically its potential covalent bonding and density compared to terrestrial ice. It posits that ice on Mars, aged 1-2 billion years, may exhibit greater density due to its unique formation conditions. The conversation explores the feasibility of drilling into Martian ice to measure electrical properties as indicators of density and questions the possibility of transporting Martian ice back to Earth without melting it. Additionally, it raises the intriguing notion of whether this ice, primarily composed of carbon, would sink in water and its potential to supercool beverages.

Might ancient mid-latitude Mar's ice be covalently bonded? Would 1-2 billion year old ice have much greater density then, compared to Earth ice? So drilling into Mars' ice, compared to drilling into Earth ice, and measuring relative difference in voltage/ampere as a proxy for relative density? Could one bring back a cube of Mars ice, without melting? Also wouldn't such guessed at Mars ice sink in water? Would it super cool your drink?

The ice is supposed to be carbon the freezing point for this is 3773 kelvin. this is easy to keep cold but hard to melt.
cheers, BT
