This week, MESSENGER's Mercury Dual Imaging System delivered the 100,000th image of Mercury since the spacecraft entered into orbit around the planet on March 18, 2011. The instrument – one of seven aboard the spacecraft – has globally mapped the planet in high-resolution monochrome images and in color images through eight of its color filters, uncovering a new view of Mercury and shedding light on the planet's geologic history. "That our inventory of orbital images of Mercury...

Dr. Seuss, Alvin Ailey Among Names Selected For 23 Mercury Craters

The International Astronomical Union (IAU) recently approved a proposal from the MESSENGER Science Team to assign 23 new names to impact craters on Mercury. The IAU has been the arbiter of planetary and satellite nomenclature since its inception in 1919. In keeping with the established naming theme for craters on Mercury, all of the newly designated features are named after famous deceased artists, musicians, or authors. The newly named craters include: - Ailey, for Alvin Ailey...

Facebook Releases Version 1.9 Of Its Android App With Updated Features

Enid Burns for RedOrbit.com Facebook recently updated its Android app with a 1.9 version that adds messaging and camera features to the mobile software. The udate is available on Google Play, and automatically updates users who already have the app installed. Initial user reviews are positive. "This finally feels like an android app," notes one user with the name Taylor on Play, who continues, "instead of an iOS clone that happens to run on android." Along with fixing a few bugs, the...

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...

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...
