🔴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...

💪🏼🦴 Muscle weakening and bone density loss – side effects of microgravity bear many similarities to ageing 🚀👵🏽 A student from TU Delft and VU Amsterdam compared effects of ageing with those of altered gravity from a cellular perspective during her internship at @esa.int 👉 www.esa.int/Enabling_Sup...
