Messenger Spacecraft Sends Back Pictures of Mercury

Hosted by

For a week now, excited astronomers have been looking at close-up images of Mercury, where temperatures range from 800° to -300°. Is it possible that the planet closest to the Sun has deposits of frozen water? In 2004, we talked with Dr. Dean Soloman as the Mercury Messenger spacecraft took off for a long complex voyage to the planet nearest the Sun. He is the principle investigator for the Mercury Mission and Director of the Department of Terrestrial Magnetism at the Carnegie Institution for Science.
