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). This is the first of three planned maneuvers designed to modify the spacecraft's orbit around Mercury as science operations transition from MESSENGER's primary orbital mission to its extended mission. MESSENGER's orbit around Mercury is highly...

MESSENGER Earns Spot On Discover Magazine's Top 100 Stories Of 2011 List
2011-12-17 05:09:23

Discover magazine has named the MESSENGER mission one of the top 100 stories of 2011. "The 100 stories here capture scientific curiosity in all its stages: provocative early results, long-sought confirmation, and many steps in the iterative process of testing theory against observation and vice versa," wrote Discover Editor-in-Chief Corey Powell in the Editor's Note for the January/February 2012 issue of the magazine. MESSENGER came in at 25 among the 100. This honor caps off a year of...

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. In 63 oral and poster presentations spanning 13 technical sessions, team scientists will report on the analysis and interpretation of observations made by MESSENGER's instruments since the spacecraft entered orbit around Mercury in March...

NASA Extends MESSENGER Mission
2011-11-15 04:32:52

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 probe became the first spacecraft to orbit the innermost planet on March 18, 2011. "We are still ironing out the funding details, but we are pleased to be able to support the continued exploration of Mercury," said NASA MESSENGER Program Scientist Ed Grayzeck, who made the announcement on November...

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. MESSENGER was 198 million kilometers (123 million miles) from Earth when the 159-second maneuver began at 6:12 p.m. EDT. Mission controllers at The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., verified the start of the maneuver about 11 minutes, 1...

Mercury Planetary Orbiter Takes Simulated Trip To The Innermost Planet
2011-10-13 03:57:25

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. During these tests the conditions the spacecraft will encounter during the cruise to Mercury and while in orbit have been simulated, and a number of tests to characterize the spacecraft performance under some worst-case scenarios have been carried out. 'Dry run' in the Large Space...

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. These findings will be presented October 5 in 30 papers and posters as part of a special session of the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society in Nantes, Frances. Scientists will also look ahead to MESSENGER observations still...

Image 1 - Mercury Has Widespread Flood Volcanism
2011-09-29 13:23:32

NASA announced on Thursday that its MESSENGER spacecraft has found new evidence that flood volcanism has been widespread on Mercury. New data from the spacecraft reveals that 6 percent of Mercury's total surface is covered by volcanic plains. "Analysis of the size of buried ℠ghost' craters in these deposits shows that the lavas are locally as thick as 2 kilometers" (or 1.2 miles), James Head of Brown University, the lead author of one of the reports published in Science, said in a...

Science Journal Has Embargoed Details Until 2 p.m. EDT on Sept. 29 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. NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft conducted fifteen laps through the inner solar system for more than six years before achieving the historic orbit insertion on March 18. Briefing participants are: -- Ed...

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...
