NASA's twin ESCAPADE spacecraft, named Red and Blue, will perform powered slingshot maneuvers above Earth on their way toward Mars. The first spacecraft's trans-Mars injection burn is scheduled for November 7, 2026, and the second's for November 9, 2026. The mission is research-stage and has not yet begun its Mars science phase.
Why it matters
ESCAPADE did not launch in the usual Mars launch window, which occurs about every 26 months, so it relies on Earth gravity assists to reach the planet. The mission is designed to study how Mars has lost its atmosphere, a question tied to the planet's loss of its global magnetic field after its molten core cooled.
The planned maneuver figures are a 9-minute burn that raises speed by about 0.64 km/s, with closest Earth approach at 965 to 1,770 km altitude. These are scheduled values from the mission plan, not yet measured results, and the outcome of the burns remains unknown until they are performed.
The players
NASA
The U.S. space agency that operates the ESCAPADE mission, which is studying Mars atmospheric loss through a twin-spacecraft formation.
The details
ESCAPADE loitered near Earth-Sun Lagrange point 2 before approaching Earth, and it flew through and observed Earth's magnetotail, the stretched region of magnetic field trailing behind the planet. Each spacecraft will fire its thrusters to boost its speed during the Earth approach, and that boost combines with Earth's gravity in a slingshot that redirects the spacecraft toward Mars. Once at Mars, the two spacecraft will fly in formation during Science Phase A, then lower and raise their orbits to around 7,000 km and 10,000 km during Science Phase B.
Timeline
November 7, 2026: First spacecraft performs trans-Mars injection burn.
November 9, 2026: Second spacecraft performs 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 nominal science mission ends.
The Tech Race
ESCAPADE is a NASA mission that departs from the conventional Mars launch-window schedule, which recurs about every 26 months, by using Earth slingshot maneuvers to reach the planet. The mission's focus on how Mars lost its atmosphere places it within ongoing planetary science research into the planet's magnetic and atmospheric history.
The mission's maneuvers affect no consumer product or service, and the ESCAPADE data will reach the public through scientific publications rather than any direct tool. Availability of findings depends on the mission's Mars science phases, which have no published public release dates beyond the schedule above.
The takeaway
Watch the November 7 and November 9, 2026 trans-Mars injection burns, which will confirm whether the slingshot plan is executed as scheduled. The Mars arrival and the start of formation flying around the planet will be the next verifiable milestones.
What happens next
The first trans-Mars injection burn is scheduled for November 7, 2026, followed by the second on November 9, 2026.
