Data collected during MESSENGER's third through sixth month in orbit around Mercury were released to the public today by the Planetary Data System (PDS), an organization that archives and distributes all of NASA's planetary mission data. With this release, data are now available to the public for the first full Mercury solar day of MESSENGER orbital operations. Calibrated data from all seven of MESSENGER's science instruments, plus radio science data from the spacecraft telecommunications...

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...

Transcriptional elongation control takes on new dimensions as Stowers researchers find gene class-specific elongation factors Life is complicated enough, so you can forgive the pioneers of DNA biology for glossing over transcriptional elongation control by RNA polymerase II, the quick and seemingly bulletproof penultimate step in the process that copies the information encoded in our DNA into protein-making instructions carried by messenger RNA. In a new report appearing in the Dec. 23,...

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...

Three NASA Missions Named PopSci's 'Best Of What's New'
2011-11-30 12:22:55

NASA's Dawn, Mars Science Laboratory and MESSENGER missions have earned recognition from Popular Science magazine as innovations worthy of the publication's "Best of What's New" Award in the aviation and space category. Dawn and Mars Science Laboratory are managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif. Dawn is currently orbiting and exploring the massive main-belt asteroid Vesta. The Mars Science Laboratory and its Curiosity rover launched on Nov. 26 on a journey to the...

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...
