Some time earlier this month, Nasa's Phoenix Lander slipped into a cold-induced
coma in the Arctic wastes of the Red Planet. With the onset of winter, the Sun
dropped low in the sky, and the temperature fell to -1,300C at night.
Apparently the Phoenix Lander's (see here, here and here) greatest contribution to science had nothing to do with Mars; it has totally rewritten everything we thought we knew about thermodynamics. No wonder the poor thing shut down.
