ESCAPADE mission will fly past Earth on November 7 and 9

The ESCAPADE mission, which launched last November, is heading to Mars. But to get there, its twin spacecraft — dubbed Blue and Gold — need to first head back to Earth. This week they’ll fly past our world, using its gravity to slingshot them on to the red planet.

The first probe, Blue, will swing past Earth on November 7, 2026, followed by the Gold probe two days later. The spacecraft will fire their engines at closest approach for an extra boost that scientists are calling a trans-Mars injection burn. This will help them increase their speeds by more than 1,000 miles an hour.

With this boost, the probes should reach Mars on September 7 and 9, 2027. There, they’ll study how charged particles from the sun interact with Mars’ magnetic environment.

Will you be able to see the flyby?

Maybe! But you’ll probably need a telescope. The two refrigerator-size space probes will fly higher than most Earth-orbiting satellites.

The western U.S. could spot the twin spacecraft before their engine burns. NASA said that the first one, Blue:

… will likely be brightest for the western U.S. between midnight and 1 a.m. PST in the early morning of November 7, and the second one [Gold] will be brightest between 1 and 2 a.m. PST on November 9.

The next viewing chance will be for those in southern Australia during the engine burns. Blue’s will be at 8:51 p.m. Australia Eastern Daylight Time on November 7. And Gold’s will begin at 9:51 p.m. Australia Eastern Daylight Time on November 9.

The spacecraft will be moving slowly compared to closer satellites. It should take a few hours for them to cross the sky from east to west.

ESCAPADE mission launched to Mars in November 2025

Blue Origin’s New Glenn rocket successfully launched the ESCAPADE mission toward Mars on November 13, 2025. The mission left from Launch Complex 36 at Cape Canaveral Space Force Station in Florida. ESCAPADE stands for Escape and Plasma Acceleration and Dynamics Explorers. The mission will use twin spacecraft, nicknamed Blue and Gold, to study Mars’ magnetic environment.

This was just the 2nd launch for the New Glenn heavy-lift launch vehicle after its initial launch in January 2025. The roar from the team was deafening on the Blue Origin feed as the reusable New Glenn booster returned and safely landed on a platform back on Earth.

Mars’ electrically charged environment

The ESCAPADE mission aims to track the internal workings of Mars’ magnetic environment. Mars doesn’t have a global magnetic field in the same sense Earth does. It doesn’t have a single, planet-wide magnetic field generated by a molten, convecting iron core (a dynamo). Earth’s global magnetic field surrounds the whole planet and creates a strong magnetosphere that protects us from the solar wind. Mars doesn’t have this in quite the same way.

But Mars does have many localized magnetic fields frozen into patches of its crust. They are remnant magnetizations, or leftovers from an ancient global magnetic field that Mars apparently had billions of years ago. Mars orbits one step farther from the sun than Earth. And it’s a smaller and colder planet than Earth. When Mars’ core cooled and its dynamo shut down, the global field collapsed. But iron-bearing rocks that had solidified while the field still existed kept their magnetization. Those patches still create small, regional magnetic fields — some surprisingly strong — especially in Mars’ southern highlands.

ESCAPADE’s goal

ESCAPADE’s goal is to study how those crustal magnetic fields interact with the solar wind. ESCAPADE’s twin spacecraft will orbit Mars to measure how solar particles and the Martian atmosphere behave around those regions of remnant magnetism. Scientists expect ESCAPADE will help them understand more of the details of how Mars lost most of its atmosphere over time, and how Mars lost its magnetosphere.

So Mars’ magnetic field is unlike those on other planets. It’s more of a hybrid. On the one hand, it’s a solar-induced magnetosphere, like that on Venus, created in part by the interaction of the solar wind with the Martian atmosphere. On the other hand, it also has localized areas of intrinsic magnetic fields from the planet’s crust. And there are larger-scale global influences as well.

Scientists want to know how energy and matter from the solar wind make their way in and out of Mars’ magnetic environment. NASA described the mission goals:

ESCAPADE will analyze how Mars’ magnetic field guides particle flows around the planet, how energy and momentum are transported from the solar wind through the magnetic environment and what processes control the flow of energy and matter into and out of the Martian atmosphere.

Details of the mission

The ESCAPADE mission is a relatively inexpensive mission with a design led by UC Berkeley. The twin spacecraft have a total cost of under $80 million. That’s only about 10% the cost of sending a typical spacecraft to Mars.

The Blue and Gold spacecraft are nicknamed for Berkeley’s school colors. The probes will orbit the red planet, taking simultaneous observations from different locations. Scientists hope to see the real-time response of Mars’ magnetic environment as it’s buffeted by the solar wind.

As with most questions astronomers aim to solve, this one also boils down to the big picture of life in our universe. Was Mars once habitable for some form of life? And could it be habitable in the future for a human population?

Bottom line: On November 7 and 9, 2026, the ESCAPADE mission’s twin probes — first Blue and then Gold — will perform flybys of Earth on the way to Mars.
