 | Volcanism has played a more extensive role in shaping the surface of Mercury than scientists had thought. This result comes from multispectral imaging data gathered in January 2008 by MESSENGER, the latest spacecraft to visit the sun's innermost planet. ...> Full Article |
 | New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground. ...> Full Article |

The planet Mercury's magnetic field appears to be strong enough to fend off the harsh solar wind from most of its surface, according to data gathered in part by a University of Michigan instrument onboard NASA's MESSENGER spacecraft.

 | One week ago, the MESSENGER spacecraft transmitted to Earth the first high-resolution image of Mercury by a spacecraft in over 30 years, since the three Mercury flybys of Mariner 10 in 1974 and 1975. MESSENGER's Wide Angle Camera (WAC), part of the Mercury Dual Imaging System (MDIS), is equipped with 11 narrow-band color filters, in contrast to the two visible-light filters and one ultraviolet filter that were on Mariner 10's vidicon camera. ...> Full Article |
 | The European Space Agency (ESA) signalled the start of a busy period for the planet Mercury, when it signed the contract for industrial development to start for the BepiColombo mission today (18th January 2008) at Astrium in Friedrichshafen, Germany. UK scientists and industry have key roles in BepiColombo, including construction of spacecraft subsystems and science instrument design. ...> Full Article |
 | When Mariner 10 flew past Mercury three times in 1974 and 1975, the same hemisphere was in sunlight during each encounter. As a consequence, Mariner 10 was able to image less than half the planet. Planetary scientists have wondered for more than 30 years about what spacecraft images might reveal about the hemisphere of Mercury that Mariner 10 never viewed. ...> Full Article |
 | NASA will point a power-packed $8.7 million University of Colorado at Boulder space instrument at some of the last unexplored terrain in the inner solar system when the MESSENGER spacecraft whips within 125 miles of Mercury's surface Jan. 14 at a mind-boggling 141,000 miles per hour. ...> Full Article |
 | MESSENGER's mid-December trajectory correction maneuver (TCM-19) went so well that the mission's design and navigation teams have decided that a TCM scheduled for January 10 will not be needed. ...> Full Article |
NASA has selected Case Western Reserve University geophysicist Steven A. Hauck II as one of 23 "participating scientists" to join a team collecting and analyzing data from the MESSENGER mission to Mercury. MESSENGER, an autonomous spacecraft, is expected to reach the innermost planet in January.

The annual Geminid meteor shower will peak on the night of Dec. 13-14. The Geminids usually offer the best show of the year, outperforming even the better-known Perseid meteor shower of August. But watching the Perseids is a pleasant way to spend a warm summer evening, while waiting outdoors on a winter night for Geminids is a bit like sitting in a refrigerator and trying to think about global warming. It can be hard to concentrate.
