Latest Mercury spacecraft Stories
MESSENGER successfully completed an orbit-correction maneuver on March 2 to lower its periapsis altitude - the lowest point of MESSENGER's orbit about Mercury relative to the planet's surface - from 405 to 200 kilometers (251 to 124 miles).
Discover magazine has named the MESSENGER mission one of the top 100 stories of 2011, coming in at 25 among the 100.
Members of the MESSENGER team will present a broad range of findings from the spacecraft's orbital investigation of Mercury during the 2011 Fall Meeting of the American Geophysical Union (AGU), which takes place this week, December 5-9, in San Francisco.
NASA has announced that it will extend the MESSENGER mission for an additional year of orbital operations at Mercury beyond the planned end of the primary mission on March 17, 2012.
The MESSENGER spacecraft successfully completed its fourth orbit-correction maneuver today to increase the period of the spacecraft's orbit around the innermost planet from 11 hours 46 minutes to a precise 12 hours.
Thermal-balance testing of the BepiColombo Mercury Planetary Orbiter Structural and Thermal Model, which has been under way in ESA's Large Space Simulator since 20 September, has been successfully completed.
MESSENGER scientists will highlight the latest results on Mercury from MESSENGER observations obtained during the first six months (the first Mercury solar day) in orbit.

NASA will host a media teleconference at 2 p.m. EDT on Thursday, Sept. 29, to discuss new data and images from the first spacecraft to orbit Mercury.
The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...
