🔧 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...

🛰️ 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... Happy #Halloween! 🦇

🛰️🖥️ Training new operators for the Large Space Simulator, Europe’s largest vacuum chamber, used to be tricky… but not anymore! The simulator recently got a digital twin - a very realistic virtual model - which will serve as a training tool and much more 👉 www.esa.int/Enabling_Sup...

🔴Moving around on Mars is tricky - its surface can be too rocky for a rover in one place, and too smooth for the navigation of a drone in another😬 During his internship with @esa.int, a robotics student investigated what would happen if a rover and a drone teamed up 🤖 🫱🏽‍🫲🏻 🚁 www.esa.int/Enabling_Sup...

📍🌕 Landing a spacecraft on the Moon with pinpoint precision while relying on ground-based tracking systems is complex and costly. A recent PhD project, co-funded by @esa.int, @dlr-en.bsky.social and OHB explored how we could teach spacecraft to find their own way 🧭🛰️ 👉 www.esa.int/Enabling_Sup...
