🔧 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...

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! 🦇

🔴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...

Have you ever wondered what it takes to drive a rover on Mars? 🤖🔴

At ESA Academy’s recent Robotics Workshop, students got a taste as they learned to operate 3D-printed ExoMy rovers. By the end of the week, the rovers were ready for their own autonomous mission 👀→🔵
