Mars Lost Ions Along the Edge of the Solar Wind
Simultaneous orbital observations tied rolling plasma instabilities to bursts of atmospheric ion escape.
Summary
Simultaneous orbital observations tied rolling plasma instabilities to bursts of atmospheric ion escape.
Researchers used simultaneous observations from multiple Mars orbiters to connect Kelvin-Helmholtz instabilities at the boundary between solar wind and the Martian upper atmosphere with bulk ion escape. The wave-like structures stirred plasma and carried atmospheric ions away from the planet. The measurements clarify one active loss mechanism and its response to the solar wind; they do not by themselves reconstruct the full history of Mars' missing atmosphere.
Why it matters
Simultaneous orbital observations tied rolling plasma instabilities to bursts of atmospheric ion escape.
Limits and context
