BepiColombo Completes A flyby Of Mercury For A Gravity Assist

The joint European-Japanese BepiColombo mission captured this view of Mercury on 1 October 2021 as the spacecraft flew past the planet for a gravity assist manoeuvre.

The Rarity Of Boulders On Mercury

An international group of planetary scientists from the United States, Russia, and Finland for the first time analyzed the abundance of boulders on Mercury and factors that determine it.

Mercury Lander: Planetary Mission Concept Study for the 2023-2032 Decadal Survey

As an end-member of terrestrial planet formation, Mercury holds unique clues about the original distribution of elements in the earliest stages of solar system development and how planets and exoplanets form and evolve in close proximity to their host stars.

Why Does Mercury Have Such A Big Iron Core? Magnetism!

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust).

Study Reveals That Mercury Is the Not-So-Shrunken Planet

Findings from a recently published paper by Smithsonian senior scientist Thomas R. Watters reveal that Mercury has managed to retain much more of its interior heat than previously thought.

Study Reveals MESSENGER Watched a Meteoroid Strike Mercury

NASA's MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) mission to Mercury has been out of operation for nearly six years, but the data it collected keeps on giving, from revealing new insights about Venus' atmosphere to providing a new way to measure the length of time neutrons can survive on their own.

Mercury's 400 C Heat May Help It make Its Own Ice

It is already hard to believe that there is ice on Mercury, where daytime temperatures reach 400 degrees Celsius, or 750 degrees Fahrenheit. Now an upcoming study says that the Vulcan heat on the planet closest to the sun likely helps make some of that ice.

A Closer Look at Mercury's Spin and Gravity Reveals The Planet's Inner Solid Core

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.
