A group of engineers celebrating receiving the first navigation signal from Celeste
🛰️ @esa.int’s Navigation Lab at ESTEC, the agency’s technical centre, received the first successful transmission of a navigation signal from a European satellite in low Earth orbit! It came from @navigation.esa.int’s Celeste mission 👉 www.esa.int/ESA_Multimed...
The first Proba-3 science results are in!
☀️🏃♀️➡️🏃♀️➡️🏃♀️➡️ Close to the Sun, it spotted solar wind moving 3–4 times faster than expected

Congratulations @exploration.esa.int!
🌒🚀 Europe is proud to have enabled #Artemis II with the European Service Module - delivering propulsion, power and life support for Orion and its crew.
Built by European industry and monitored 24/7 by ESA teams, the ESM is a strong example of ESA technologies.

The task of an attitude control system is to make sure a spacecraft points exactly where it needs to 🛰️🫵 In the case of CubeSpec, that target will be a star ✨ Learn more about how we make sure this pointing instrument is as accurate as possible 👉 www.esa.int/ESA_Multimed...
Graphene lights the way. Literally.
Watch how aerogel cubes made of graphene react to light in microgravity. This innovative material could revolutionise propulsion beyond Earth. 🚀

3D-printed lens antenna at Jammertest
Some satellite navigation antennas offer protection from the most common types of interference, but are bulky and expensive.
PhD researcher at ESA’s Navigation Laboratory explored a simpler and cheaper alternative: a football-sized, 3D-printed lens antenna ⚽📡 www.esa.int/Enabling_Sup...
Scientists have been exploring how GPS and Galileo reflected signals can help monitor sea ice, using innovative data from @spire.com.

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!

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?) 🔥

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!
