Gravity soon will kill the Messenger.

The NASA spacecraft that launched in 2004 from Cape Canaveral, Fla., and became the first to orbit Mercury in 2011 is on course to crash into the planet's surface April 30 at more than 8,700 mph. Ref. Source 3

Mercury

NASA's Messenger space probe has crashed into Mercury after running out of fuel, ending a nearly 11-year journey that provided valuable data and photos.

The agency estimates the probe hit the surface at 8,750 miles per hour and created an impact crater 52 feet (16 meters) in diameter. The crash wasn't visible from Earth because it occurred on the far side of Mercury.

Messenger was the first spacecraft to orbit Mercury, the planet closest to the sun. It traveled about 5 billion miles -- a journey that included 15 trips around the sun. Ref. CNN

Mercury's origins traced to rare meteorite


Geologists trace Mercury's origins to weird, rare meteorite, and find planet cooled dramatically shortly after it formed. Ref. Source 8o.

Surface of Mercury arose from deep inside the planet

Researchers have found that several volcanic deposits on Mercury's surface require mantle melting to have started close to the planet's core-mantle boundary, which lies only 400 km below the planets surface and making it unique in the solar system. Ref. Source 7m.

Most volcanic activity on Mercury stopped about 3.5 billion years ago

New research finds that major volcanic activity on the planet Mercury most likely ended about 3.5 billion years ago. These findings add insight into the geological evolution of Mercury in particular, and what happens when rocky planets cool and contract in general. Ref. Source 3n.

Small collisions make big impact on Mercury's thin atmosphere. Mercury, our smallest planetary neighbor, has very little to call an atmosphere, but it does have a strange weather pattern: morning micro-meteor showers. Source 4p.

Understanding Mercury's magnetic tail. Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging mission. The origin of energetic electrons detected in Mercury's magnetic tail has puzzled scientists. This new study provides a possible solution to how these energetic electrons form. Source 9s.
