Scientists have been exploring how GPS and Galileo reflected signals can help monitor sea ice, using innovative data from @spire.com.
A promising new way to observe our rapidly changing polar regions:

At @esa.int’s technical centre, student teams have been getting familiar with the Orbital Robotics Laboratory facilities. 🤖
This is part of the ESA Academy Experiments programme, where students from all over Europe can apply to conduct their research at ESA. 🔎

Curious about life as an ESA #EGT? 🤔 Here’s what some of our current TEC graduates have to say: www.linkedin.com/feed/update/...
On 17 February, there was an annular solar eclipse visible only from Antarctica… and from space!
👇ESA’s Proba-2 satellite recorded the same eclipse no less than four times as it whizzed round Earth!

A romantic candlelit dinner... in space? 🕯️🍽️🌹
Sounds great, if ‘spooky’ is the vibe you’re going for 👻
Happy #ValentinesDay ❤️
Looks like you preferred to ✨observe✨ for a while before joining! Welcome 👋
And we wouldn't give up the spot for any other mission 😉 As much as we love Proba-3, we must admit Draco is also pretty cool (or hot?) 🔥

The latest student teams to perform their ESA Academy experiments at @esa.int’s robotics labs:
🦾 tested autonomous crawling
⚖️ tricked the human body’s balance system
🦎 grasped objects with a gecko-inspired arm

We shouldn’t have favourite missions…but we all secretly do, don’t we? 😉
👀 Our eyes on the Sun’s inner corona, that’s Proba-3! In a 5-hour window, the formation-flying mission captured not 1… not 2… but 3 solar prominence eruptions – structures made of relatively cold plasma extending outwards from the Sun ☀️👉 www.esa.int/ESA_Multimed...
Celeste is on the way, testing ways of making Galileo #satnav even better!
These low-orbiting test satellites are part of ESA’s FutureNAV programme – get the full background in our latest ESA Highlights publication: www.esa.int/About_Us/ESA...
3D model of ESA's Test Centre at ESTEC
🛰️🚀 Ever wanted to visit a place where satellites and rockets are tested before they are sent to space?
Now you can do the next best thing!
Take a peek inside the walls of @esa.int’s Test Centre at ESTEC through the recently updated virtual tour 👀 www.esa.int/ESA_Multimed...
🔭 Until now, observing the inner regions of the Sun’s enigmatic atmosphere – the corona – was close to impossible.
🛰️🛰️☀️ The satellite duo making up @esa.int’s Proba-3 mission fills this observation gap by creating artificial solar eclipses in orbit 👉 www.esa.int/Enabling_Sup...

🚯 To clean up orbits around Earth, we first need to identify and approach individual pieces of space debris. 🛰️ Two companies from Luxembourg are developing the eyes 👀 for satellites to be able to do just that 👉 www.esa.int/ESA_Multimed...
🟥 Rolling out the red carpet for Mars exploration takes a couple of hinges.
⚙️ Here's the mechanism that will allow @esa.int's ExoMars Rosalind Franklin rover to step onto the martian surface.

📢 🎧 New podcast alert! @esa.int’s Discovery and Preparation programme supports research that pushes boundaries of what’s possible – and now the team are sharing the innovation stories through a new podcast series. Listen to the first episode here 👉 open.spotify.com/episode/72VH...
☀️ Lessons from the November 2025 solar storm
Last week, Earth was hit by a large solar storm. The event provided an opportunity for multiple ESA missions, whether orbiting Earth or far into deep space, to collect radiation data, which is now being analysed.

Testing the first ever metal part 3D-printed in space
🔧 Testing space metal 🤘
In February, @esa.int’s engineers received a very special package 📦 Inside was the first metal part 3D-printed in space, coming all the way from the ISS 🛰️ Since the unboxing, the space metal has been through A LOT 👉 www.esa.int/Enabling_Sup...
🏠🌕 To live on the Moon or Mars, we would need technologies that can use local resources to create materials essential for our survival. The University of Bremen explored if the unique conditions of space itself could help us with this 👉 www.esa.int/Enabling_Sup...
An essential building block for phased array antennas
🛰️ Our current radio frequency ‘highways’ that carry information to and from satellites are getting congested.
📡 @thalesaleniaspace.bsky.social develops key building blocks for next-generation antennas operating at a very special frequency that can offer more bandwidth 👉 www.esa.int/ESA_Multimed...
Booooo!! 👻 It’s #SpookySeason!
Can you guess what's making this candle's flame flicker? 🕯️
Is it...
a) ghost
b) microgravity
We know it’s tricky, so we’re treating you to the answer 🎃 www.esa.int/ESA_Multimed...
