Sometimes, Mars just seems to smile back at you 🙂
Chloride-bearing terrain on Mars does not stand out in regular black-and-white images but shows up a distinct pink to purple hue in colour-infrared images, making ESA's ExoMars CaSSIS instrument a unique tool to study the distribution of salts across Mars from orbit. In the absence of colour, chlorides are easily confused with other light-toned materials such as clays. This image shows a salt deposit in a crater with the appearance of a 'smiley'.

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. 👀 blogs.esa.int/to-mars-and-ba…

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 👉 esa.int/ESA_Multimedia/Image…

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: esa.int/ESA_Multimedia/Image…

🧑‍🎄 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 👀 Find out more 👉esa.int/Science_Exploration/…

A green glow in the martian night

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.int/Science_Exploration/… #ExploreFarther [1/2]
Infographic showing how oddly ‘light’ carbon monoxide forms in Mars’ atmosphere. It shows carbon dioxide molecules being split by sunlight to form carbon monoxide and oxygen, with an illustration of Mars' red-hued surface below.

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: mars.nasa.gov/news/9113/nasa… [2/2]
