🌈 Leiden Canal Pride Parade 2025: ESA Joins the Celebration Again! 🌈
We’re thrilled to announce that for the second year in a row, ESA ESTEC, our technical heart in the Netherlands, will proudly participate in the Leiden Canal Pride Parade! 🚣🏾♀️🏳️🌈
Join us on Saturday at 13:30 CEST as the boat parade sets off from the beautiful Galgewater, sailing through Leiden’s stunning historic city center until about 17:00 CEST.
Here’s the route we’ll be cruising:
- Departure from Galgewater
- Clockwise sailing to Turfmarkt
- Passing through Oude Singel/Oude Vest
- Along the Haven
- Following the Oude Rijn
- And rounding off at Apothekersdijk
- Ending back at the Galgewater
Come cheer us on and let’s celebrate diversity together! #SpaceForAll ❤️

Today at #ESTEC in 🇳🇱 we celebrate 30 years of ESA Navigation activities, which resulted in the world's most accurate satellite navigation system, Galileo - one of our 50 hallmark achievements in our 50 year anniversary!
📢 You are invited to the 7th @esa#Quantum Technology Conference, the reference point and hub for European institutions, space industry, and academia involved in quantum technologies for space! 📅 7-9 October in Crete, Greece at @FORTH_ITE. Early bird registration still open: nikal.eventsair.com/7th-quan…
OK, so it’s hot – but is it unusually hot? ESA satellites have been tracking the temperature of Earth’s oceans (where most excess atmospheric heat goes) for the past 3 decades to help tackle this question…
Just one of our agency’s hallmark achievements listed in our new #ESADelivers publication – read the other 49 here! esa.int/About_Us/ESA_Publica…
