Investigating whether life has ever existed on Mars. @ESA_TGO in orbit since 2016, Rosalind Franklin rover launch TBC

👋 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.

@ESA_Tech @esa Ok, but is planetary protection expensive? 🤔

Our experts have their say: https://t.co/BNG6mJmrQD

@ESA_Tech ▶️  Watch @esa’s Mars chief engineer Albert Haldemann explain the sterilisation of one of the parachutes for the #ExoMars Rosalind Franklin rover mission and why it matters.

🧭 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.

🆕 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.

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.

Drop it like it's... on Mars 🤟

European engineers are testing our four-legged #ExoMars landing platform by dropping it onto simulated martian surfaces.

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.

#3IATLAS update: we've just pinpointed the comet's path with 10 times more accuracy, using data from our @ESA_ExoMars Trace Gas Orbiter 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. 💨

🆕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!

First images of comet #3I/ATLAS from Europe's Mars orbiters 😍

Observing the comet from 30 million km away, #ExoMars reveals the halo of gas and dust surrounding the comet's nucleus.

📢 New episode featuring @esa's ExoMars Rosalind Franklin rover!

🍿 Watch the most sophisticated laboratory set to work on Mars in action. Like a factory floor, an automated sequence drives material through the lab.

[Human Spaceflight @esaspaceflight]

🪂 The largest parachute to ever fly on Mars deployed gracefully on Earth, slowing down an @ESA_ExoMars dummy descent module for a safe touchdown.

Watch this slow-motion footage captured from the capsule after its release at nearly 30 km above the Arctic Circle.

📽️ Vorticity

[Human Spaceflight @esaspaceflight]

A tiny @ESA_ExoMars capsule rockets off at 4000 km per hour to simulate the aerodynamics of a Mars descent.

This supersonic test happened in the blink of an eye, captured here in slow motion.

🌟 Mars star.

Meet @esa's ExoMars Rosalind Franklin rover at @NHM_London and explore one of the biggest questions of our time: Could life exist beyond Earth?

🔴 https://t.co/rEx4P7yevC

[Human Spaceflight @esaspaceflight]

For decades, scientists have been puzzled by intriguing streak features down slopes on Mars 🤔

🧹 Something sweeping dust?
🌊 Underground water seeping out?
🌪️ Dust devils at work?

@esa's ExoMars Trace Gas Orbiter helps find an answer: https://t.co/Qt6G7Tj4vQ

[Human Spaceflight @esaspaceflight]

📈 The @ESA_ExoMars Rosalind Franklin rover will make use of this fleet to send precious science data back to Earth.

🛰️ The orbiters are essential for returning imagery and science data from the rovers on Mars, which can be as far as 400 million km away.

🌐 The Mars Relay Network is a collaboration between @NASA and @ESA with international partners 🤝.

[Human Spaceflight @esaspaceflight]

As the #HeraMission flew past planet Mars, we kept a close watch on Oxia Planum, the landing site for the @ESA_ExoMars Rosalind Franklin mission.

Can you spot the area where Europe plans to land a rover to search for signs of life on Mars in 2030?
