Craters in the Caloris Basin on Mercury
This image features several craters near the eastern edge of the Caloris basin. The larger craters have excavated low reflectance material, and both have hollows forming within their floors.

Mercury
Planetary scientists are announcing today a new explanation of the current rotational state of the planet Mercury. The report is being presented by Dr. Benoit Noyelles of the University of Namur, Belgium, to the meeting of the Division for Planetary Sciences of the American Astronomical Society, held in Denver, CO.

1,000th Featured Image from the Mercury MESSENGER Spacecraft
The MESSENGER project is celebrating the posting today of the 1,000th featured image from Mercury. The Mercury Dual Imaging System (MDIS) team has posted a new image to the MESSENGER website approximately once per business day since March 29, 2011, when the first image obtained from orbit about the innermost planet was made public.

Mercury: Fiery Yellow, Scattered Blue
This false color image shows a bright fresh crater exhibiting possible evidence of a pyroclastic deposit on it's eastern side (shown by the bright yellow); as well as a series of secondaries which have excavated sub-surface material resulting in the blues seen in the north-east corner of the image.

NASA and Italian Space Agency Sign Agreement on Exploration of Mercury
At a meeting in Rome Thursday, NASA Administrator Charles Bolden and Italian Space Agency (ASI) President Enrico Saggese signed a Memorandum of Understanding for cooperation on the European Space Agency- (ESA) led BepiColombo mission to Mercury, strengthening mutually beneficial cooperation between NASA and ASI in planetary exploration.

A View of Mercury From Afar
This image of Mercury, acquired by the Mercury Dual Imaging System (MDIS) aboard NASA's MESSENGER mission on April 23, 2013, allows us to take a step back to view the planet.

Mercury 100% Coverage
At the very end of 2012, MESSENGER obtained the final image needed to view 100% of Mercury's surface under daylight conditions. The mosaics shown here cover all of Mercury's surface and were produced by using the monochrome mosaic released by NASA's Planetary Data System (PDS) on March 8, 2013, as the base. The full resolution mosaics are available for download on MESSENGER's Global Mosaics webpage.

MESSENGER Completes Its 2,000th Orbit of Mercury
MESSENGER began its 2,000th orbit around Mercury earlier this week, on May 22. The spacecraft completed its primary mission on March 17, 2012, and its first extended mission on March 17, 2013.

Influence of an inner core on the long-period forced librations of Mercury
The planetary perturbations on Mercury's orbit lead to long-period forced librations of Mercury's mantle. These librations have previously been studied for a planet with two layers: a mantle and a liquid core.

Radar Exposes Mercury's Interior
Researchers working with high-precision planetary radars, including the Goldstone Solar System Radar of NASA's Jet Propulsion Laboratory, Pasadena, Calif., have discovered strong evidence that the planet Mercury has a molten core

The Sun Sends Two CMEs Toward Mercury
On the night of April 24 and the morning of April 25, 2013, the sun erupted with two coronal mass ejections (CMEs), solar phenomena that can send billions of tons of solar particles into space that can affect electronic systems in satellites.

First Meteorite From Mercury Found?
Early in 2012, someone in Southern Morocco picked up 35 greenish stones, including the one shown above. Purchased by a dealer in Erfoud, Morocco, it was then resold to Stefan Ralew, a meteorite collector from Berlin.

Newly Named Craters on Mercury
The International Astronomical Union (IAU) - the arbiter of planetary and satellite nomenclature since its inception in 1919 - recently approved a proposal from the MESSENGER Science Team to assign names to nine impact craters on Mercury. 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 or other contributors to the humanities.
