NASA's Twin Spacecraft Will Execute Powered Slingshot Maneuvers on Their Way to Mars
Confirmed
In Short: NASA's twin ESCAPADE spacecraft have completed powered Earth flyby maneuvers, setting them on course for Mars in 2027.
NASA's twin ESCAPADE spacecraft have successfully executed powered Earth flyby maneuvers, a first for the agency, as they head towards Mars.
Acting associate flight director Asal Naseri of NASA's Heliophysics Division noted, 'This is the first time NASA has used a powered Earth flyby to propel a spacecraft toward Mars, and we’ve now executed this maneuver twice, flawlessly, in just two days.'
The ESCAPADE spacecraft, launched on Nov. 13, 2025, from Cape Canaveral Space Force Station, Florida, performed these maneuvers to take advantage of Earth and Mars being favorably aligned.
Both spacecraft entered a 'loiter' orbit around Earth before performing their respective engine burns.
The first spacecraft, dubbed Blue, burned its engines for over 9 minutes starting at 5 a.m., while the second, Gold, followed suit two days later at 6 a.m.
These maneuvers are part of a unique mission plan that involves the spacecraft loitering around Earth for nearly a year before making their final pass and heading towards Mars.
Rob Lillis, ESCAPADE’s principal investigator and associate director for planetary science at the Berkeley Space Sciences Lab, praised the operations team, saying, 'Our fantastic operations team put 110% into this critical maneuver, getting the spacecraft ready and watching like hawks for potential issues. We’re excited to now focus on our interplanetary journey. Onward, to Mars!'
Once at Mars, the ESCAPADE spacecraft will be the first to fly in formation around the planet, providing unprecedented insights into the Martian environment.
By studying the Martian magnetosphere and how it interacts with the solar wind, ESCAPADE aims to uncover more about how Mars lost its ancient atmosphere.
Michele Cash, ESCAPADE program scientist at NASA headquarters, highlighted the mission's potential impact on future human exploration of Mars, stating, 'By better understanding how the solar wind affects the Martian environment, ESCAPADE’s findings could help us plan and prepare for future human exploration of the Red Planet.'
What this adds
The ESCAPADE mission marks a new approach in space exploration, utilizing powered Earth flybys to optimize trajectories to Mars.
The spacecraft's formation flying will enable scientists to study the Martian environment from multiple vantage points simultaneously, providing a more comprehensive understanding of the planet's dynamics.

- NASA’s two ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft have each successfully completed a powered Earth flyby, using Earth’s gravity in combination with a sustained engine burn to slingshot themselves toward Mars.
- So instead of heading straight for the Red Planet, as most other Mars missions have done, both spacecraft entered a “loiter” or “Earth-proximity” orbit.
What's still developing
- This led to some bonus science, where the spacecraft flew through and observed Earth's magnetotail.
- A single spacecraft wouldn't be able to tell if changes it observes are due to changes in these interactions, or changes in its position.
- It's becoming clear, if not certain, that Mars was once warm and wet.
- This animation shows the ESCAPADE spacecraft in their String of Pearls formation above Mars.
- A pair of NASA are spacecraft are about to perform a slingshot maneuver above Earth, and some of us might get to see them.
