NASA's Twin ESCAPADE Probes Complete Powered Earth Flybys, Head to Mars

NASA's twin ESCAPADE spacecraft completed powered Earth flybys on Nov. 7 and Nov. 9, 2026, using Earth's gravity and engine burns to slingshot toward Mars, with arrival planned for September 2027.

In brief

  • NASA's twin ESCAPADE spacecraft completed powered Earth flybys on Nov. 7 and Nov. 9, 2026.
  • The burns were the first time NASA used a powered Earth flyby to send a spacecraft toward Mars.
  • The spacecraft are on a 10-month cruise to Mars, with arrival planned for September 2027.
  • ESCAPADE is led by UC Berkeley's Space Sciences Laboratory under NASA's SIMPLEx program.

NASA's Twin ESCAPADE Probes Complete Powered Earth Flybys, Head to Mars

NASA's twin ESCAPADE spacecraft have completed powered Earth flybys and are now en route to Mars, the agency announced on Nov. 9, 2026.

The Maneuvers

The first spacecraft completed its close approach and approximately 9-minute trans-Mars injection burn at 5 a.m. EST on Nov. 7, when it was about 1,000 miles above Earth's surface. The second spacecraft followed two days later, completing its close approach and engine burn at 6 a.m. EST on Nov. 9, when it was about 650 miles above the planet's surface.

"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," said Asal Naseri, acting associate flight director for the Heliophysics Division at NASA Headquarters in Washington.

The Path to Mars

The two ESCAPADE spacecraft launched from Cape Canaveral Space Force Station in Florida on Nov. 13, 2025, aboard a Blue Origin New Glenn rocket. Because Earth and Mars were on opposite sides of the Sun at launch, the spacecraft entered a kidney-bean-shaped "loiter" orbit around the Earth-Sun Lagrange point 2, about a million miles from Earth. They returned to Earth in November 2026 to use the planet's gravity to slingshot toward Mars.

"With this loiter orbit and Earth flyby, ESCAPADE is pioneering a new strategy for getting to Mars," said Jeff Parker of Advanced Space, lead mission designer. "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 powered flybys set both spacecraft on course for a 10-month cruise to Mars. Mars orbit insertion burns are planned for Sept. 7 and Sept. 9, 2027. Once in orbit, the two spacecraft will fly in formation to study how the solar wind interacts with the Martian environment and drives atmospheric loss.

Science and Partners

"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," said Michele Cash, ESCAPADE program scientist at NASA Headquarters.

The mission is funded by NASA's Heliophysics Division and is part of the SIMPLEx (Small Innovative Missions for Planetary Exploration) program. The University of California, Berkeley's Space Sciences Laboratory leads the mission with key partners Rocket Lab, NASA's Goddard Space Flight Center, Embry-Riddle Aeronautical University, Advanced Space, and Blue Origin.

"This will be the first science mission to choreograph two orbiters around Mars, and the first time we will be able to make coordinated observations of the Martian environment from two different locations simultaneously," said ESCAPADE's principal investigator, Rob Lillis of the University of California, Berkeley.

Why it matters

  • ESCAPADE is the first NASA mission to use a powered Earth flyby to propel a spacecraft toward Mars.
  • The loiter orbit strategy allows launch flexibility outside the traditional 26-month Earth-Mars alignment window.
  • The twin spacecraft will conduct the first coordinated two-point observations of the Martian environment from orbit.
