In Depth | Mercury - NASA Solar System Exploration
Mercury's exosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium. Magnetosphere. Magnetosphere. Mercury's magnetic field is offset relative to the planet's equator. Though Mercury's magnetic field at the surface has just 1% the strength of Earth's, it interacts with the magnetic field of the solar wind to sometimes ...

Mercury Lander Mission Concept Study - NASA Solar System Exploration
The purpose of this study was to determine the feasibility of a landed mission to Mercury. It was conducted by the JHU/APL Space Department in partnership with Marshall Space Flight Center, Glen Research Center, and Steven Hauck from Case Western Reserve University. This was conducted as a concept maturity level (CML) 3 study focusing on feasibility trades and options for concepts with a goal ...
What is a Planet? | Planets – NASA Solar System Exploration
It is unlike the terrestrial planets (Mercury, Venus, Earth, Mars), or the gas giants (Jupiter, Saturn), or the ice giants (Uranus, Neptune). Charon, its huge satellite, is nearly half the size of Pluto and shares Pluto's orbit. Though Pluto kept its planetary status through the 1980s, things began to change in the 1990s with some new ...

NASA Team Studies Middle-aged Sun by Tracking Motion of Mercury
Short for Mercury Surface, Space Environment, Geochemistry, and Ranging, the robotic spacecraft made three flybys of Mercury in 2008 and 2009 and orbited the planet from March 2011 through April 2015. The scientists worked backward, analyzing subtle changes in Mercury’s motion as a way of learning about the Sun and how its physical parameters ...
