NASA's ESCAPADE mission will send a pair of twin probes to Mars to study how the solar wind has stripped away the planet’s atmosphere, leaving behind the desolate surface we see today.

Hundreds of advocates joined The Planetary Society and partner organizations in Washington, D.C., to urge Congress to protect NASA’s science budget. Hear from Ari Koeppel, Britney Schmidt, Bill Nye, Rep. Glenn Ivey, Marcel Agüeros, Brandon Jones, and Casey Dreier about this historic Day of Action.
