    "body_text": "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.",
