Solar Wind at Martian Moon Could Impact Future Missions
Mars has two moons, Phobos and Deimos. Both are small, airless bodies with irregular shapes. Because they lack protective atmospheres and magnetospheres, Phobos and Deimos are directly exposed to the solar wind for part of their orbits....

Electric Wind of Venus
Venus has an "electric wind" strong enough to remove the components of water from its upper atmosphere. This action may have played a significant role in stripping Earth's twin planet of its oceans, according to new research results from...

NASA | Mars Atmosphere Loss: Sputtering
How did Mars, a once wet planet, lose its early atmosphere? One possibility is through a process called "sputtering," in which atoms are knocked away from the atmosphere due to impacts with energetic particles.
