The primary goal of the ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission is to investigate the interaction between the solar wind—a constant, million-mile-per-hour stream of charged particles from the Sun—and the Martian atmosphere. Scientists believe this process gradually eroded the planet’s air over billions of years, causing its climate to cool and surface water to disappear. The mission is led by the University of California, Berkeley, with the spacecraft built by Rocket Lab.
Acting NASA Administrator Sean Duffy congratulated the partners on the successful launch, noting the mission will provide critical insights into Mars’ dramatic climate history. Furthermore, the data collected will be vital for preparing for future human exploration of the Red Planet.
“Understanding Martian space weather is a top priority for future missions because it helps us protect systems, robots, and most importantly, humans, in extreme environments,” said Nicky Fox, associate administrator for NASA’s Science Mission Directorate.
Ground controllers established communication with both spacecraft shortly after the launch. In addition to the Mars-bound probes, the New Glenn rocket carried a technology demonstration for Viasat Inc., funded by NASA. This test successfully used a commercial satellite network to relay launch telemetry, advancing the agency’s goal of using next-generation commercial communication services for its science missions.
