ExoMars orbiter

ESA's Trace Gas Orbiter, analysing methane & other atmospheric gases that may be related to active biology or geology on Mars.

Sometimes, Mars just seems to smile back at you 🙂

Two European spacecraft play hide and seek around Mars for new atmospheric science. 🫣📡📶

🃏 @ESA_TGO has a new capability under its sleeve: mutual radio occultation. For the first time, underused short-range antennas from the Trace Gas Orbiter and Mars Express are put to work to probe the martian atmosphere.

That’s right, I see Mars in a whole range of colours! 😍 Scientists on Earth find it useful to reveal the planet’s composition and decipher a landscape that took shape 3.6 billion years ago.

Zoom in on my high-resolution view of the landscape below 👉 https://t.co/FUWsQOivdz

Metallic Mars 🤘🏼

A new image reveals a heavy presence of iron, magnesium and aluminium in the Mawrth Vallis region.

👀 We call it the Red Planet, but a fine camera on Europe's Trace Gas Orbiter can capture more colours on Mars than our eyes can see: https://t.co/bIdl3rMhkJ

🧑‍🎄 Getting ready for Christmas? I'm getting ready for #Mars ‘solar conjunction season’ 🔴🌞🌍

Happening roughly once every 25 months, during this period the Red Planet is located on the opposite side of the Sun from Earth, making it tricky for me and other spacecraft at Mars to talk to Earth.

🆕science alert! I've spotted a green glow 🟢 lighting up Mars's night sky – something long suspected to exist but never spotted before.
Under clear skies, the glow could be bright enough for humans and rovers to see by 👀

Excitingly, this clarifies a tantalising puzzle found by @MarsCuriosity in 2022. Curiosity saw that rock samples from Gale Crater were also weirdly lacking in heavy carbon – a signature that’s typically associated with life here on Earth. Background: https://t.co/smfgh0QhWt [2/2]

New science alert! I’ve spotted something weird in Mars' atmosphere! 🔴🛰️🔍

Turns out that #Mars' carbon monoxide is ‘lighter’ than it should be. But why?

Could biology be to blame… or is it all a matter of chemistry? 🤔 ☀️

[ESA_ExoMars @ESA_ExoMars]

Our dear Trace Gas Orbiter, @ESA_TGO, will send a mysterious signal to #Earth tonight.

😱 Should we be scared?
🤩 Excited?
🧐 Curious?

Follow this simulated #FirstContact and help decode the secret message. 👽

[ESA Operations @esaoperations]

How would you feel if extraterrestrials got in touch?👽🛸👋〰️📡🌍🤔

[ESA Operations @esaoperations]

This evening, @ESA_TGO will transmit an encoded message to Earth, simulating #FirstContact by an extraterrestrial civilisation in a global art project pondering life beyond Earth

Can you decode the #SignInSpace? https://t.co/jRr0ymK3ya

Red Mars, blue Mars… ever wondered why my images are typically blue?!
Enjoy this 🆕 image of #Mars, part of Alga Crater, and look through my @ExoMars_CaSSIS eyes to dig deeper into the reasons why I see Mars this way 🔴👀https://t.co/MUjLEvVxYT

#Mars has always been on the horizon for space exploration.

Here is a handy overview of @ESA's ambitions for the Red Planet, including sending Europeans to Mars by 2040. 🤩👩‍🚀🔴 #ExploreFarther

#OTD 19 October 2016, #ESA's #ExoMars2016 @ESA_TGO entered #Mars orbit, only the 2nd time that ESA has placed a spacecraft into orbit around the Red Planet 🔴 🛰️ @esascience 👉 https://t.co/e3ZKYml83N

The devil’s in the detail 😈 – and you won’t want to miss even a scrap of the detail in this amazing view of #Mars from @ExoMars_CaSSIS! 🤩

This chaotic, windswept landscape is covered by eerie dust devil tracks 🔴🌪️

Just me, or does this impact crater look like a tree stump with characteristic rings?! Worlds apart, but just as tree rings provide snapshots of Earth’s past climate, the patterns inside this ice-rich crater reveal details of Mars history #ExploreFarther

📸Ritchey Crater (309.06°E, 28.13°S) has exposed bedrock, variety of impactites and post-impact materials. RGB images show what you would see but my filters (NIR-RED-PAN-BLU) help differentiate various materials. Can you 👀 the differences ? #Mars #UniBern #ExoMars #ESA #Roscomos
