🔴 There is hot news coming from Mars. For the first time, orbital data is revealing signs of young volcanism. Deep down, Mars might not be geologically dead, just sleeping. @esa’s Trace Gas Orbiter detected hydrogen chloride, a gas that escapes from volcanic vents on Earth: esa.int/articles/news-media/…

😱 In space, no one can hear you scream... 🕵️ Can you guess where in the Solar System we took this image? Hint: @esa’s Trace Gas Orbiter captured it on an autumn day. 🎃 #HappyHalloween 📸: @ESA/@ESA_TGO/CaSSIS/@unibern

A prolific decade in Mars orbit. @esa’s Trace Gas Orbiter slipped into orbit around Mars at 17:24 CEST on 19 October 2016. Here are some impressive facts and figures about our largest Mars explorer 👇

🔴 Before @esa's Rosalind Franklin rover can explore Mars, it must first drive off its lander. 🪨 We might touch down on a slope or on top of a rock, and we will only have one chance to get it right. Once the rover leaves the landing platform, there is no way back. esa.int/Science_Exploration/…

▶️ Separation for Mars, in slow motion. 🔴 European engineers are recreating the moment the #ExoMars lander breaks away from its backshell as it travels at 125km/h, less than 1km above the martian surface. 🎦 @esa, @Thales_Alenia_S, @AirbusSpace, Sener

After travelling millions of km through deep space, @ESA_ExoMars will stretch out its four legs 🦿 Tests confirm our landing legs can deploy automatically in less than a second, ready for touchdown on Mars the moment the front shield is jettisoned. 🎦 @esa, @Thales_Alenia_S, @AirbusSpace, Sener

👋 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.
☑️Closest approach! Distance: 2,800 miles Speed: 12,300 mph

🧭 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_Exploration/…

🆕 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_Exploration/…

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 orbiters falls silent. This is because solar atmosphere blocks radio signals between Earth and the spacecraft.

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 caused by seasonal changes stirring up dust and wind. 💨 esa.int/ESA_Multimedia/Image…
