NASA's twin ESCAPADE spacecraft, launched from Cape Canaveral Space Force Station in Florida on Nov. 13, 2025, have successfully completed powered Earth flyby maneuvers, setting them on course for Mars in September 2027. The ESCAPADE mission, consisting of the Blue and Gold spacecraft, executed these maneuvers to gain extra speed and align their trajectory for the journey to Mars.
The ESCAPADE spacecraft, known as the Escape and Plasma Acceleration and Dynamics Explorers, launched when Earth and Mars were on opposite sides of the Sun. This launch timing is part of a strategy that allows for more flexible launch windows, as opposed to the traditional 26-month launch windows when the planets are favorably aligned.
On November 7, 2026, at 10:29 UTC, ESCAPADE Blue performed its maneuver at an altitude of 938 kilometers. Two days later, on November 9, 2026, ESCAPADE Gold followed suit at an altitude of 731 kilometers. Both spacecraft executed a 9-minute engine burn, known as the Oberth maneuver, to increase their speed from roughly 6.3 miles per second to approximately 6.7 miles per second, a boost of more than 1,000 miles per hour.
Asal Naseri, acting associate flight director for the Heliophysics Division at NASA Headquarters in Washington, praised the mission's success. '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,' she said.
The ESCAPADE mission initially aimed to launch in October 2024 but faced delays, leading to a reevaluation and the development of a 'loitering' orbit. The mission's principal investigator, Rob Lillis, a planetary and space physicist at the University of California, Berkeley, emphasized the uniqueness of the mission. 'No NASA mission has ever done this before,' Lillis said.
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. This method provides the flexibility to launch almost anytime and then use Earth's gravity to get a boost to Mars, rather than waiting every two years to launch there directly when the planets are aligned.
The ESCAPADE mission aims to study the Martian environment, including its magnetic fields and interactions with the solar wind. 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, making the twin spacecraft approach particularly valuable.
Both spacecraft are now on course for Mars, with arrival expected in September 2027. The mission's success marks a significant milestone in NASA's exploration of the Red Planet and showcases innovative techniques for interplanetary travel.
What this adds
The ESCAPADE mission's success demonstrates the effectiveness of using Earth's gravity to boost spacecraft towards Mars, a technique that provides more flexible launch windows and reduces the need for direct alignment between Earth and Mars.

What's confirmed
- The two ESCAPADE spacecraft launched from Cape Canaveral Space Force Station in Florida on Nov. 13, 2025, when Earth and Mars were on opposite sides of the Sun.

- Home » Science » NASA’s ESCAPADE Spacecraft Complete Unique Earth Flyby to Propel Towards Mars Twin NASA spacecraft, known as the Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE), are nearing the end of a year-long journey, preparing to embark on a mission to Mars.
What's still developing
- Most missions to Mars leave Earth during a relatively short launch window that opens roughly every 26 months, when the positions of the two planets allow spacecraft to make the journey with comparatively little fuel.
- Though its global magnetosphere is long gone, Mars still has patches of magnetic fields called crustal magnetic fields, or remnant magnetic fields.
- During both flybys, the Rocket Lab-built spacecraft fired their engines, using a principle called the Oberth effect to maximize the performance of the maneuver.
