Mercury is the closest planet to the Sun in Earth’s solar system, but has no moons and no substantial atmosphere.
Mercury These colorful composite new images of Mercury, provide colorful diversity of surface materials in never seen before detail. The Mercury Atmosphere and Surface Composition Spectrometer (MASCS) instrument aboard
NASA’s MESSENGER spacecraft was designed to study both the exosphere and surface of the planet Mercury.
Published on Jun 11, 2013 All of Mercury Image Credit: NASA/JHU Applied Physics Lab/Carnegie Inst. Washington For the first time,
the entire surface of planet Mercury has been mapped. Detailed observations of the innermost planet's surprising
crust have been ongoing since the robotic MESSENGER spacecraft first passed Mercury in 2008 and began orbiting in 2011.
Previously, much of the Mercury's surface was unknown as it is too far for Earth-bound telescopes to see clearly,...

This is the THe Messenger main website
MESSENGER launched from Cape Canaveral Air Force Station on August 3, 2004. It entered orbit around Mercury on March 18, 2011,
the first spacecraft ever to do so. Since then it has performed countless observations of our Solar System’s innermost planet
and has successfully mapped 100% of its surface. Check out the infographic below showing some of the amazing numbers racked up by
MESSENGER since its launch ten years ago
A little over a week before NASA’s MAVEN spacecraft fired its rockets to successfully enter orbit around Mars,
MESSENGER performed a little burn of its own – the second of four orbit correction maneuvers (OCMs) that will allow
it to remain in orbit around Mercury until next March. Although it is closing in on the end of its operational life
it’s nice to know we still have a few more months of images and discoveries from MESSENGER to look forward to!
Delaying Death: Mercury Spacecraft Firing Engines To Stay Up Until 2015

Don’t take these spectacular Mercury images (below the jump) for granted.
Three weeks ago, NASA’s orbiting Mercury spacecraft did an engine fire to boost its altitude above the hothouse planet.
Another one is scheduled for January.
An Oblique View of Abedin Is One of MESSENGER’s Final Scenes
The possibly-volcanic crater Adedin on Mercury by MESSENGER.
Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington. The 72-mile (116-km) -wide crater Adedin is seen at an oblique angle in this mosaic made from images
acquired by NASA’s MESSENGER spacecraft. The angle highlights the crater’s central peak complex which surrounds
a shallow depression that could have a volcanic origin, as well as fine cracks in the floor of its basin and a slumped
and terraced section of its far wall. The crater was named after the Bangladeshi painter Zainul Abedin (1914-1976).

Mercury MESSENGER Mission Concludes with a Smashing Finale!
by BOB KING on APRIL 30, 2015
Over and out! This is the final image acquired and transmitted back to Earth by MESSENGER this afternoon, April 30, 2015.
We’re seeing a small area 0.6 miles (1 km) across on the floor of the 93-kilometer-diameter crater Jokai.
The spacecraft struck the planet just north of Shakespeare basin at the predicted time.

Name That Crater On Mercury! MESSENGER Team Opens Public Contest

Here’s your rare chance to leave a lasting mark on a piece of the Solar System. The team behind the MESSENGER spacecraft —
that machine orbiting Mercury since 2011 — is asking the public to help them name craters on the planet, in an open contest.
Get a Change of View of Mercury’s North Pole
by JASON MAJOR on JANUARY 5, 2015
A forced perspective view of Prokofiev crater near Mercury’s north pole
It’s always good to get a little change of perspective, and with this image we achieve just that:
it’s a view of Mercury’s north pole projected as it might be seen from above a slightly more southerly latitude.
Thanks to the MESSENGER spacecraft, with which this image was originally acquired, as well as the Arecibo Observatory here on Earth,
scientists now know that these polar craters contain large deposits of water ice – which may seem surprising on an airless
and searing-hot planet located so close to the Sun but not when you realize that the interiors of these craters never actually receive sunlight.

The Stunning Highs and Lows of Mercury
Published on May 6, 2016 Data from NASA’s MESSENGER mission have been used to create this animation of the first global digital elevation model (DEM) of Mercury,
revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize its
geologic history. Mercury’s surface is colored according to the topography of the surface, with regions with higher elevations colored brown,
yellow, and red, and regions with lower elevations shown in blue and purple.
The MESSENGER spacecraft was launched on Aug. 3, 2004, and began orbiting Mercury on March 17, 2011.
It spent four years capturing images and information about the planet closest to the sun in unprecedented detail.

Scientists Create Global Topographic Map of Mercury
A team of scientists from NASA, the U.S. Geological Survey, Arizona State University, Carnegie Institute of Washington
and Johns Hopkins University Applied Physics Laboratory has created the first global topographic map of the planet Mercury.
Topographic map of Mercury with labeled features. Mercury’s surface is colored according the topography of the surface,
with regions with higher elevations colored brown, yellow and red, and regions with lower elevations appearing blue and purple.
The highest elevation on the planet is located just south of the equator, and about 2.5 miles above Mercury’s average elevation.
The lowest elevation, which is more than three miles below Mercury’s average, is found on the floor of Rachmaninoff basin,
a basin suspected to host some of the most recent volcanic deposits on the planet.

The planet Mercury, the closet planet to our Sun, is something of an exercise in extremes. Its days last longer than its years and at any given time, its sun-facing side is scorching hot while its dark side is freezing cold. It is also one of the least understood planets in our Solar System. While it is a terrestrial (i.e. rocky) planet like Earth, Venus and Mars, it has a significantly higher iron-to-rock ratio than the others.

After facing down a couple of delays due to technical difficulties, Europe’s and Japan’s first Mercury orbiter is entering some
of the final stages ahead of its 2016 launch. Part of the BepiColombo orbiter moved into a European testing facility
this past week that will shake, bake and otherwise test the hardware to make sure it’s ready for its extreme mission.
