The MESSENGER mission successfully completed the first of two maneuvers designed to reduce the spacecraft's orbital period about Mercury. This new trajectory will pave the way for more detailed measurements and targeted observations of the Sun's closest neighbor. The spacecraft was 124 million kilometers (77 million miles) from Earth when the 188-second maneuver began at 3:13 p.m. EDT. Mission controllers at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md.,...

Thursday night, images from MESSENGER's Mercury Dual Imaging System made their debut on the CBS sitcom, "The Big Bang Theory." The award-winning comedy centers on five characters: roommates Sheldon Cooper and Leonard Hofstadter, two physicists who work at the California Institute of Technology; and Sheldon's and Leonard's equally geeky and socially awkward friends and co-workers, aerospace engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali; and Penny, a blonde waitress and...

Messenger Completes Mercury Mission

In Roman mythology Mercury was the “Messenger of the Gods,” — as well as a god of trade, thieves and travel. It is thus fitting — apart from the trade and thieves aspect — that the MESSENGER program has been so carefully studying the inner most planet in our solar system. MErcury, Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) this week successfully completed a year-long mission to perform the first complete reconnaissance of the...

On March 17, 2012, MESSENGER successfully wrapped up a year-long campaign to perform the first complete reconnaissance of the geochemistry, geophysics, geologic history, atmosphere, magnetosphere, and plasma environment of the solar system's innermost planet. The following day, March 18, 2012, marked the official start of an extended phase designed to build upon those discoveries. What MESSENGER has accomplished since its launch in August 2004 is "amazing," says MESSENGER Mission Systems...

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...

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...
