NASA twin spacecraft depart Earth orbit to begin Mars mission

NASA's ESCAPADE mission has initiated its journey as two identical spacecraft, designed to study Mars' magnetosphere, separated and deployed from Blue Origin's New Glenn upper stage. Both probes will spend the next year in a unique Earth-bound orbit before executing a trans-Mars injection burn in November 2026, employing the Oberth Effect to maximize mission fuel efficiency.

The paired orbiters, engineered by Rocket Lab and overseen by UC Berkeley, mark the first Mars science effort to place two coordinated satellites into distinct Martian orbits for synchronized measurement campaigns. Arrival at Mars is set for September 2027, when a staged insertion and gradual orbital refinement will position both craft for simultaneous data collection starting in spring 2028.

Scientific objectives for ESCAPADE include charting Mars' response to solar phenomena, measuring dynamic atmospheric changes, and quantifying the flow of solar wind particles and the resultant energy transfer inside the Martian magnetosphere. The dataset will help mission planners design improved shielding for future crewed and robotic Mars missions.

ESCAPADE stands out as a flagship initiative in NASA's SIMPLEx program, funded by the Heliophysics Division and managed by the Kennedy Space Center's Launch Services Program under the VADR contract.

NASA's ESCAPADE mission to Mars - twin UC Berkeley satellites dubbed Blue and Gold - will launch in early November
Berkeley, CA (SPX) Nov 06, 2025
The first dual-satellite mission to another planet, NASA's ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers), is scheduled for launch no earlier than Sunday, Nov. 9, from Cape Canaveral, Florida. The two identical spacecraft are managed and operated by the University of California, Berkeley, and will fly in formation to map the magnetic fields, upper atmosphere and ionosphere of Mars in 3D, providing the first stereo view of the Red Planet's unique near-space environment.
