SIMPLEx program

Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) is a spacecraft mission to Mars consisting of two spacecraft known as Blue and Gold, which launched in November 2025. The mission is designed to demonstrate low-cost planetary space exploration. The twin spacecraft will study Mars' magnetosphere and how solar wind contributed to the loss of most of the planet's atmosphere over Solar System history. The mission is led by UC Berkeley's Space Sciences Laboratory with Dr. Robert Lillis as Principal Investigator. It is part of NASA's SIMPLEx program.
