Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil.<\/p>\n

The main culprit is a relentless stream of particles from the Sun,\u00a0known as\u00a0the solar wind. Over billions of years, the solar wind has stripped\u00a0away much of\u00a0the Martian atmosphere, causing the planet to cool and its\u00a0surface\u00a0water to evaporate.<\/p>\n

Now, NASA\u2019s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission, which launched<\/a>\u00a0on Nov. 13, 2025, has turned on the science instruments that will investigate how this happened and how the Sun continues to influence the Red Planet.\u00a0The science instruments, which are all operating as of Feb. 25, also will study\u00a0space weather<\/a>\u00a0in new ways near Earth and on the way to Mars.<\/p>\n

At Mars, ESCAPADE\u2019s findings could also help NASA protect future explorers from the harsh Martian conditions.<\/p>\n

\u201cThe pioneering ESCAPADE duo will not only investigate the Sun\u2019s role in transforming Mars into an uninhabitable planet, but also will help inform the development of space weather protocols for solar events directed at Mars during future human missions to the Red Planet,\u201d said Joe Westlake, heliophysics division director at NASA Headquarters in Washington. \u201cBy joining the heliophysics fleet of missions across the solar system, ESCAPADE will be another weather station making humans and technology in space safer and more successful.\u201d<\/p>\n

First of its kind<\/strong><\/h3>\n

With its twin spacecraft,\u00a0ESCAPADE<\/a>\u00a0is the first science mission to coordinate two\u00a0orbiters around Mars, gaining a perspective we\u2019ve never had before.\u00a0Together, the ESCAPADE twins will\u00a0measure short-term changes in the\u00a0magnetized environment around Mars, called the\u00a0magnetosphere, and uncover real-time processes driving the planet\u2019s atmospheric escape.<\/p>\n

\u201cHaving two spacecraft is going to help us understand cause and effect \u2014 how the solar wind, when it comes to Mars, interacts with the magnetic field,\u201d\u00a0said\u00a0Michele Cash, ESCAPADE program scientist\u00a0at NASA Headquarters.<\/p>\n

The ESCAPADE orbiters build on earlier\u00a0Mars missions that have studied Mars\u2019 atmosphere, but with just one spacecraft.<\/p>\n

\u201cThe ESCAPADE mission is a game changer,\u201d said Rob Lillis, the mission\u2019s principal investigator at the University of California, Berkeley. \u201cIt gives us what you might call a stereo perspective \u2014 two different vantage points simultaneously.\u201d<\/p>\n

Once ESCAPADE reaches Mars, its twin spacecraft will follow each other\u00a0in the same orbit, passing over the same areas at different times to uncover when and where changes are happening.<\/p>\n

\u201cWhen we have two spacecraft crossing those regions in quick succession, we can monitor how those regions vary on timescales as short as two\u00a0minutes,\u201d Lillis said. \u201cThis will allow us to make measurements we could never make before.\u201d<\/p>\n

After six months, the two spacecraft will shift into different orbits,\u00a0with one traveling farther from Mars and the other staying closer to it. Planned to last for five months, this second formation aims to study the solar wind and Martian magnetosphere simultaneously, allowing scientists to investigate how Mars responds to the solar wind in real time.<\/p>\n

\u201cPrior spacecraft could either be in the upstream solar wind, or they could be close to the planet measuring its magnetosphere,\u201d Lillis said, \u201cbut ESCAPADE allows us to be in two places at once and to simultaneously measure the cause and the effect.\u201d<\/p>\n

Preparing for human exploration<\/strong><\/h3>\n

When\u00a0people set foot on Mars, they will not be as well protected from solar radiation as their family and\u00a0friends on Earth.<\/p>\n

Earth can withstand\u00a0the solar wind\u2019s ceaseless onslaught because it has a hardy magnetic field that shields us from the Sun\u2019s energetic particles. However, Mars\u2019 once robust magnetic field has weakened over time. Today it\u2019s a patchwork of localized magnetism in the planet\u2019s crust along with\u00a0an ever-changing magnetic field generated by the solar wind\u2019s interaction with charged particles in Mars\u2019 upper atmosphere.<\/p>\n

Mars has a hybrid magnetosphere made up of an induced magnetic field from the solar wind and crustal magnetic fields from the planet\u2019s surface. In this artist\u2019s concept yellow lines represent magnetic field lines from the Sun carried by the solar wind and blue lines represent Martian surface magnetic fields. White sparks indicate reconnection activity, where field lines break and reconnect, and red lines are reconnected magnetic fields that link the Martian surface to space.\u00a0

This \u201chybrid\u201d magnetosphere provides\u00a0little protection against the atmosphere-stripping force of the solar wind. This, plus Mars\u2019 thin atmosphere, allows the Sun\u2019s energetic particles to easily reach the Martian surface, endangering\u00a0future human explorers there.<\/p>\n

\u201cBefore we send humans to Mars, we need to understand what type of environment these astronauts are going to encounter,\u201d Cash said.<\/p>\n

Additionally, ESCAPADE will provide more information about Mars\u2019 ionosphere \u2014 part of the upper atmosphere that future astronauts will use to send radio and navigation signals around the planet, as we do on Earth.<\/p>\n

\u201cIf we ever want GPS at Mars or long-distance communications, we need to understand the ionosphere,\u201d Lillis said.<\/p>\n

Unique journey to Mars<\/strong><\/h3>\n

Previous Mars missions have launched when Earth and Mars are aligned in their orbits, which only happens every 26 months. But ESCAPADE launched early, pioneering a new strategy that allows Mars-bound spacecraft to launch almost anytime.<\/p>\n

Instead of heading directly to Mars, ESCAPADE\u2019s spacecraft are first looping around a location in space a million miles from Earth called Lagrange point 2. In November 2026, when Earth and Mars are aligned, the ESCAPADE spacecraft will return to Earth and use our planet\u2019s gravity to slingshot themselves toward Mars for a September 2027 arrival.<\/p>\n

NASA\u2019s two ESCAPADE spacecraft are not traveling directly from Earth to Mars but are first making a kidney-bean-shaped loop around a location in space called Lagrange point 2 (L2). A small black triangle shows approximately where the spacecraft were on Feb. 24, 2026. In November 2026, when Earth and Mars are more closely aligned in their orbits, the spacecraft will return to Earth and use our planet\u2019s gravity to slingshot their way to Mars.<\/div>\n

This unique \u201cloiter\u201d orbit will extend approximately 2 million miles from our planet, making the ESCAPADE spacecraft the first to fly through a previously unexplored region of Earth\u2019s distant magnetotail, part of Earth\u2019s magnetosphere opposite the Sun.<\/p>\n

\u201cWe\u2019re going to be doing some discovery science,\u201d Lillis said. \u201cNo one has ever measured Earth\u2019s tail this far away.\u201d<\/p>\n

The solar wind compresses the Sunward side of Earth\u2019s magnetosphere and stretches the opposite side into a long tail, called the magnetotail. The two ESCAPADE spacecraft (indicated here in cyan) will be the first to fly through the distant part of Earth\u2019s magnetotail, about 1.2 million miles from Earth, before heading to Mars.<\/div>\n

Later, during their 10-month cruise to Mars, ESCAPADE\u2019s two spacecraft will study solar wind and the interplanetary magnetic environment that Mars-bound astronauts will also traverse, preparing for future journeys to the Red Planet.<\/p>\n

The ESCAPADE mission is funded by NASA\u2019s Heliophysics Division and is part of the NASA Small Innovative Missions for Planetary Exploration program.\u00a0UC Berkeley\u2019s Space Sciences Laboratory leads the mission with key partners\u00a0Rocket Lab; NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland; Embry-Riddle Aeronautical University; Advanced Space; and Blue Origin.<\/p>\n<\/p>\n
