Earth's Moon and Mercury, the closest planet to the Sun, may contain significantly more water ice than previously thought, according to a new analysis of data from NASA's LRO and MESSENGER spacecraft.

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it -- very, very carefully.

The Chemical Composition of Mercury

The chemical composition of a planetary body reflects its starting conditions modified by numerous processes during its formation and geological evolution.

Mapping Geological Features on Mercury

Mercury, the innermost planet of our Solar System is a grey, barren world to our human eyes.

Mercury, our smallest planetary neighbor, has very little to call an atmosphere, but it does have a strange weather pattern: morning micro-meteor showers.

The scorching hot surface of Mercury seems like an unlikely place to find ice, but research over the past three decades has suggested that water is frozen on the first rock from the Sun, hidden away on crater floors that are permanently shadowed from the Sun's blistering rays.

The European Space Agency held a media briefing at ESA's technical centre in the Netherlands on July 6 to discuss the upcoming mission BepiColombo to Mercury.

Great Valley Found on Mercury

Scientists have discovered a new large valley on Mercury that may be the first evidence of buckling of the planet's outer silicate shell in response to global contraction.

Mercury is Tectonically Active

It's small, it's hot, and it's shrinking. New NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet.

New research from North Carolina State University finds that major volcanic activity on the planet Mercury most likely ended about 3.5 billion years ago.

Russian plans to send a lander to Ganymede, the Laplace mission, and an orbiter to Mercury. This video from the Russian space agency ROSCOMOS provides an update on the missions.

Preparing BepiColombo For Mercury

The ESA-JAXA BepiColombo mission to Mercury must withstand extremely harsh conditions while in orbit around the innermost planet of our Solar System.

Around 4.6 billion years ago, the universe was a chaos of collapsing gas and spinning debris.

Around 13 times per century, Mercury passes between Earth and the sun in a rare astronomical event known as a planetary transit.

The MESSENGER mission has released 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 characterize fully the planet's geologic history.

Watch Mercury Transit The Sun

NASA is inviting media and viewers around the world to see a relatively rare celestial event, with coverage of the Monday, May 9 transit of the sun by the planet Mercury.

Scientists have long been puzzled about what makes Mercury's surface so dark.

The planet Mercury is being pelted regularly by bits of dust from an ancient comet, a new study has concluded.

Modules of the BepiColombo spacecraft, which will be on public view during the Sunday 4 October Open Day of ESA's ESTEC technical centre in the Netherlands.

About 4 billion years ago, Mercury's magnetic field could have been much stronger than today, as indicated by low-altitude observations made by NASA's MESSENGER spacecraft that revealed evidence of magnetization of ancient crustal rocks on Mercury.
