Mars
Fourth planet from the Sun
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", for its orange-red appearance. Mars is a desert-like rocky planet with a tenuous atmosphere that is primarily carbon dioxide (CO2).
European Space Agency
European organisation dedicated to space exploration
The European Space Agency (ESA), pronounced 'ee-sah', is a 23-member international organisation devoted to space exploration. It has its headquarters in Paris and a staff of around 2,547 people globally as of 2023. ESA was founded in 1975 in the context of European integration.

Why It Matters
This event matters because it provides crucial data about how solar storms affect planetary environments beyond Earth, which is essential for future human exploration of Mars. The observations help scientists understand radiation risks to astronauts and equipment during solar events. This research also contributes to our knowledge of planetary atmospheric evolution and space weather impacts across the solar system.
Context & Background
- Mars lacks a global magnetic field like Earth's, making its atmosphere more vulnerable to solar radiation and atmospheric stripping
- Solar superstorms are massive eruptions of charged particles from the Sun that can disrupt electronics and increase radiation levels
- ESA currently operates multiple Mars orbiters including the ExoMars Trace Gas Orbiter and Mars Express
- NASA's MAVEN orbiter has previously studied atmospheric loss on Mars, showing solar activity accelerates atmospheric escape
- Understanding space weather effects is critical for planning crewed Mars missions, which NASA and SpaceX aim to conduct in the 2030s
What Happens Next
Scientists will analyze the collected data to quantify atmospheric loss rates during extreme solar events and model radiation exposure risks. ESA will likely coordinate with NASA to compare findings from different Mars orbiters. The research will inform future Mars mission designs, including radiation shielding requirements and optimal mission timing relative to solar cycles.
Frequently Asked Questions
Mars lacks Earth's strong global magnetic field that deflects charged particles. Without this protection, solar radiation directly interacts with Mars' atmosphere, causing atmospheric particles to be stripped away into space.
ESA's Mars orbiters including the ExoMars Trace Gas Orbiter and Mars Express monitored the event. These spacecraft carry instruments that measure radiation, atmospheric composition, and solar particle impacts on the Martian environment.
The data helps quantify radiation risks astronauts would face during solar events. This informs spacecraft and habitat shielding requirements, emergency protocols, and optimal mission timing to avoid peak solar activity periods.
Yes, but Earth's magnetic field provides significant protection. Extreme solar storms can still disrupt satellites, power grids, and communications on Earth, though atmospheric stripping isn't a concern like on Mars.
Charged particles from solar storms energize atmospheric molecules in Mars' upper atmosphere, giving them enough energy to escape Mars' gravity. This contributes to the planet's ongoing atmospheric loss over geological timescales.
