More Ice on Mercury’s South Pole
Evidence for water ice has been found in Mercury’s permanently shadowed regions (PSR) of the two poles using MESSENGER’s radar images with limited resolution and spatial coverage. Using the Arecibo […]

The abstract deadline for the Mercury 2018 Meeting: Current and Future Science of the Innermost Planet is a few weeks away, on February 15, 2018. This meeting will focus on […]
Recent modeling by Steve Mojzsis and colleagues suggests that the large volume of impactors during the late accretion phase almost entirely resurfaced Mercury. This material induced extensive melting (~58%) of […]
We are pleased to announce a session on Mercury at the 2015 AGU Fall Meeting in San Francisco, CA, December 14–18, 2015. NASA’s MESSENGER spacecraft completed more than four years […]
The robotic spacecraft MESSENGER has run out of fuel. With no way to make major adjustments to its orbit around the planet Mercury, the probe will smash into the surface […]
There will be a MESSENGER MDIS Data Users’ Workshop held in association with LPSC on Sunday, March 15, 2015 at 1:30 pm. The workshop will feature hands on examples of using MDIS […]
The closest planet to the sun appears to get hit by a periodic meteor shower, possibly associated with a comet that produces multiple events annually on Earth. The clues pointing […]
NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft has provided the first optical images of ice and other frozen volatile materials within permanently shadowed craters near Mercury’s north […]
The Planetary Data System is pleased to announce Release 12 of data collected by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission, including raw and calibrated products acquired […]
We invite contributions to a special session on Mercury at the 2014 AGU Fall Meeting in San Francisco, CA, December 15–19, 2014. NASA’s MESSENGER mission, now nearing the fourth and final […]
On April 20, MESSENGER completed its 3,000th orbit of Mercury and moved closer to the planet than any spacecraft has been before, dropping to an altitude of 199 kilometers (123.7 […]
MESSENGER has now returned more than 200,000 images acquired from orbit about Mercury. The 1996 proposal for the mission promised a return of at least 1,000 images says Robert Gold, […]
We invite you to attend the special session on Mercury at the 2013 AGU Fall Meeting on December 9. The session includes two sets of oral presentations, featuring papers on Mercury’s geological […]
NASA’s Mercury-orbiting MESSENGER spacecraft has captured images of two comets — 2P/Encke and C/2012 S1 (ISON) — setting the stage for observations later this month when both comets will be […]
The May 2013 issue of the Discovery and New Frontiers News is on the Discovery Program website. In this issue: What caused the uneven gravity on the Moon, a mystery since […]
