👋 A spacecraft is flying by the Red Planet, just 4500 km away. 👀 While @NASA's #MissionToPsyche slingshots around Mars, two @esa spacecraft are watching. 📷 Stay tuned for images coming to us through the eyes of the ExoMars Trace Gas Orbiter and Mars Express.

🧭 Which way to Mars for less space radiation, please? ☢️ Data from @esa's ExoMars Trace Gas Orbiter confirms that travelling during solar maximum is the safest time for a trip #ToMarsAndBack. 🤯 The radiation paradox: esa.int/Science_Explor…

🆕 Cast your mind back to May 2024... remember how a massive solar storm triggered northern lights across Europe? We can now reveal how this same solar storm affected Mars, thanks to clever teamwork from our two Mars orbiters. Find out more 👉 esa.int/Science_Explor…

Out of Mars, lost in space. 🌪️ A new study reveals how some water disappeared from the Red Planet. The culprit: a rare, intense dust storm driving water vapour 80 kilometres up into the martian atmosphere. blogs.esa.int/to-mars-and-ba… @ESA_TGO @iaa_csic @UTokyo_News_en @BIRA_IASB

There is a blackout between Mars and Earth, and the Sun is to blame. 🔴⚫️🌍 🌞 Once every 25 months, our star passes between these two planets. The alignment is called solar conjunction. 🔇 While the Sun blocks our view of Mars until 21 January, communication with our martian

SWOOSH! 🧹 When a meteoroid struck Mars, it triggered ~100 dust avalanches down the slopes of an ancient volcano. @esa's ExoMars Trace Gas Orbiter captured the dramatic effect of this rare cascade. A new study in @NatureComms suggests that most streaks on the Red Planet are

🆕Researchers combed through images from ESA's #MarsExpress & #ExoMars spacecraft to find 1039 swirling dust devils 🌪️ Using these dust devils to track raging winds on Mars, their findings include that the strongest winds blow much faster than we thought! Read more 👉
