NASA's twin ESCAPADE spacecraft, named Red and Blue, will perform powered slingshot maneuvers above Earth on November 7 and November 9, 2026, to send them toward Mars. Each trans-Mars injection burn will last about 9 minutes, boosting speed from roughly 10.14 km/s to 10.78 km/s.
Why it matters
ESCAPADE did not launch in the usual Mars launch window, which occurs about every 26 months, so the spacecraft rely on Earth's gravity and thruster boosts to reach the planet. The mission will fly in formation around Mars to study atmospheric loss on a planet that lost its global magnetic field after its molten core cooled.
The planned trans-Mars injection burns will raise spacecraft speed by about 0.64 km/s over roughly 9 minutes per burn, with closest Earth approach between about 965 and 1,770 kilometers altitude. Mission timing beyond the November burns and the outcome of formation flying remain unconfirmed in the source data.
The players
NASA
The National Aeronautics and Space Administration is the United States government agency that leads civil space exploration and operates the ESCAPADE mission.
The details
The two spacecraft loitered near Earth-Sun Lagrange point 2 before approaching Earth, where they flew through and observed Earth's magnetotail. During Science Phase A, which lasts about 6 months, the pair will fly in formation around Mars, after which Blue will lower its orbit to about 7,000 kilometers and Red will raise its orbit to about 10,000 kilometers during the roughly 5-month Science Phase B.
Timeline
November 7, 2026: The first spacecraft performs its trans-Mars injection burn.
November 9, 2026: The second spacecraft performs its trans-Mars injection burn.
About 6 months after Mars arrival: Science Phase A formation flying concludes and Science Phase B begins.
About 5 months after Science Phase B begins: ESCAPADE's nominal science mission ends.
Seasonal Patterns
ESCAPADE missed the Mars launch window that recurs roughly every 26 months and instead uses Earth-gravity slingshot boosts to reach the planet. This approach departs from the conventional timing that governs most Mars missions.
The slingshot maneuvers and formation flying could help scientists understand how Mars lost its atmosphere, informing future planetary research. Any eventual findings on atmospheric loss would be pragmatic for designing future robotic missions to the Red Planet.
The takeaway
Mission planners sometimes must use indirect routes, such as Earth slingshot burns, when a conventional launch window is missed. Watching the November burns will show how well those maneuvers perform in practice.
What happens next
The first trans-Mars injection burn is scheduled for November 7, 2026, and the second for November 9, 2026.
