Scientists from NASA’s MESSENGER mission share some of its top discoveries — and lingering mysteries — in a new compendium.
Mercury’s dark surface is revealing intriguing new clues about the formation of the solar system, including evidence announced today that the planet closest to the Sun may have formed in part from carbon, a key component of life.
Alien orbits you plied,

NASA’s MESSENGER spacecraft has been orbiting Mercury for the last four years, giving scientists an unprecedented look at our solar system’s innermost planet. But now the craft’s fuel supply is exhausted; inexorably drawn in by Mercury’s gravity, it is scheduled to crash in April. Sean Solomon, director of Columbia University’s Lamont-Doherty Earth Observatory, has been leading the mission, and in this video, he talks about its implications.
Sean Solomon, director of the Lamont-Doherty Earth Observatory and a geophysicist who has spent much of his career studying Earth’s neighboring planets as well as the Earth itself, will receive the National Medal of Science.
Mercury, the planet closest to the Sun, may hold at least 100 billion tons of ice in permanently shaded craters near its north pole, NASA scientists announced Thursday. The findings come as NASA’s MESSENGER spacecraft nears its second year of orbit around Mercury. MESSENGER’s lead investigator, Sean Solomon, is director of Columbia University’s Lamont-Doherty Earth Observatory.
