Mercury: inside Track
Baked and irradiated, Mercury is a cratered world. The pock-marks created by impactors that rained from space during the early Solar System. Mercury, with double sunrises has a day twice as long as its year. Scientists think there may be ice on Mercury, deposited by comets, perpetually shadowed from the scorch of the Sun.
