Each maneuver combined Earth’s gravitational influence with an engine firing lasting approximately nine minutes. [NASA](https://www.nasa.gov/) [reported the completed maneuvers](https://science.nasa.gov/science-research/heliophysics/nasas-escapade-completes-powered-earth-flybys-now-en-route-to-mars/) on November 9. The first spacecraft passed approximately 1,000 miles above Earth at about 5 a.m. EST on November 7. The second followed two days later at about 6 a.m. EST, passing roughly 650 miles above the surface. The spacecraft are now on a ten-month cruise, with Mars orbit insertion planned for September 7 and 9, 2027. ## A Route Through Earth’s Neighborhood ESCAPADE launched from Cape Canaveral on a [Blue Origin](https://www.blueorigin.com/) New Glenn rocket on November 13, 2025. Earth and Mars were then on opposite sides of the Sun. The mission initially entered an Earth-proximity trajectory rather than beginning a direct transfer to Mars. The spacecraft traveled around the region of the Sun–Earth second Lagrange point, approximately one million miles from Earth on the side facing away from the Sun. Their route then returned them toward Earth for the November 2026 encounters. The engine burns during those flybys supplied the trans-Mars injection maneuvers. A powered flyby combines a gravitational encounter with a spacecraft’s own propulsion. The planet alters the trajectory, and the engine firing changes the spacecraft’s velocity as it passes. ESCAPADE used the combination to depart Earth’s neighborhood on a path that intersects Mars at the planned arrival time. ## Two Spacecraft for the Same Physical System The Escape and Plasma Acceleration and Dynamics Explorers mission is led by the University of California, Berkeley’s Space Sciences Laboratory. Its [science and operations team](https://escapade.ssl.berkeley.edu/about/) studies how energy and momentum from the solar wind pass through Mars’ magnetic environment and drive atmospheric escape. The solar wind is a flow of charged particles emitted by the Sun. ESCAPADE’s two spacecraft provide separate observation points within that environment. This arrangement supports measurements of changes across space as well as changes over time. A feature measured at one spacecraft can be compared with conditions measured by the other, rather than treating every variation along a single spacecraft’s path as a change at the whole planet. The mission examines ion escape and sputtering. Ion escape involves electrically charged atmospheric particles leaving the planet. In sputtering, energetic particles strike atmospheric material and can transfer enough energy to eject it. Both processes connect the surrounding space environment to the gradual loss of atmospheric matter. The instruments also characterize space weather and the ionosphere, the electrically charged part of the atmosphere. Variations in this region affect the passage of communication and navigation signals. ESCAPADE’s measurements address the particles and fields involved in those changes. ## Blue and Gold [Rocket Lab](https://rocketlabcorp.com/home/) designed and built the twin spacecraft, named Blue and Gold, at its Long Beach, California, facility. They use the company’s [Explorer spacecraft platform](https://rocketlabcorp.com/missions/esCAPADE/), configured for interplanetary operations and substantial changes in velocity. The manufacturer supplied spacecraft subsystems including propulsion equipment, solar panels, radios, reaction wheels, star trackers, and flight computers. The star trackers support orientation by observing stars. Reaction wheels adjust spacecraft attitude, allowing the vehicle to point its instruments and other equipment. Propulsion changes the trajectory, whereas attitude control manages the direction in which the spacecraft faces. Those functions operate together during a planned engine maneuver. Berkeley is responsible for mission management, systems engineering, navigation, operations, and science-data processing and archiving. It also supplies the electron and ion electrostatic analyzers. [NASA](https://www.nasa.gov/) Goddard Space Flight Center provides magnetometers, and Embry-Riddle Aeronautical University provides Langmuir probes. Advanced Space supplies mission-design expertise. The instruments measure complementary properties of the plasma environment. Particle analyzers examine charged particles, magnetometers measure magnetic fields, and Langmuir probes sample properties of the surrounding plasma. Combining those observations helps connect particle motion with the fields and local conditions in which it occurs. ## Science During the Journey and at Mars The spacecraft have already collected observations during passages through Earth’s magnetotail, the extended part of the planet’s magnetic environment on the side away from the Sun. During the Mars cruise, the pair can observe the solar wind between the two planets. Trajectory-correction maneuvers will adjust the approach to Mars. NASA plans approximately 11-minute orbit-insertion burns for each spacecraft in September 2027. Subsequent maneuvers will establish the initial science formation. Science operations are expected to begin in June 2028, with both spacecraft following the same orbit to compare changes with time and location. After six months, the mission plans to separate the spacecraft into different orbits for a five-month campaign. One will travel farther from Mars to measure the incoming solar wind, and the other will remain closer to measure the planet’s response. This coordinated arrangement connects the external flow of particles with the atmospheric and magnetic processes it produces around Mars.
