Seat back 💺 Relax 🧘‍♀️ And enjoy the flight ✈️ … unless satellite communications are disrupted 🛰️ www.esa.int/Applications... 🧵👇🏼

#OTD in 2000, the first telecoms 🌐, navigation🧭 and earth observation🌍️ satellite system was used in an emergency to help during the Thynne Mountain forest fire in British Columbia, Canada🍁 @navigation.esa.int @esaearth.esa.int

#OTD 7 years ago, EDRS-C launched aboard an Ariane 5🚀 Dubbed SpaceDataHighway, the European Data Relay System, used laser tech to relay Earth observation images back to the ground, beaming the data back almost immediately and thereby accelerating emergency response down here🚑️ 🌍️ @transport.esa.int

🎥Movie streaming takes less than a second today thanks to decades of innovation in satellite broadcasting 📺 #OTD in 1984, the European Communications Satellite 2 launched aboard Ariane 3 flight V10, expanding sat comms and international TV across Europe🛰️🌍 @esa.int @eurospacehistory.bsky.social

How will these observatories be adapted to connect to satellites? Find out 👇️ resilience.esa.int/archives/new...

The development will help enable more resilient, secure, and high-bandwidth data transmission across Europe💪 🇪🇺

We can't get enough of these stunning observatory images 🤩⚡️ More to come as @esa.int and the National Observatory of Athens sign a Memorandum of Intent to develop ground optical technologies in Greece, the essential Earth-based links connecting with satellites via laser comms 🇬🇷 Thread for more👇️

Are you ready to shape our programmes' strategy and communicate to various stakeholders?🤔 We have a job opening for a Programme and Strategy Coordinator within the Directorate of Resilience, Navigation and Connectivity, based in ESTEC (Netherlands). Details 👉️ jobs.esa.int/job/Noordwij...

🇱🇺 just upgraded international quantum-secure communications🔐 Developed under an @esa.int Partnership Project, the Optical Ground Station built by HITEC Luxembourg in a consortium led by Starion Luxembourg will help distribute quantum cryptographic keys through future international secure networks ⚛️

🤔How do we measure the impact of our programmes? Curious about this question as well? Apply for the Junior Professional in Market Intelligence role and investigate the relevance of our projects in resilience, navigation and connectivity 💪 🧭 📶 Deadline 28 July 2026: jobs.esa.int/job/Harwell-...

🌒 The first Moon landing over 50 years ago proved we could get there. The next step is making it easier to return and stay there. @esa.int's Moonlight is developing the communication and navigation infrastructure to make that possible 📶 🧭 #InternationalMoonDay resilience.esa.int/moonlight

🍁Happy Canada Day to our Cooperating State 🇨🇦 ESA recently signed a contract with Canadian satellite communications company Kepler to help advance Hydron - the 'fibre of the sky'⚡️ All for better connectivity on space thanks to optical communications www.esa.int/Applications...

What if you could impact the future of Direct-to-Device (D2D) communications?📱🚙 ESA is hiring a Mission Manager for our D2D projects 👇️ jobs.esa.int/job/Noordwij...

We wouldn't build cities on Earth without roads, comms and navigation. The same is true for the Moon🌒 ESA's Moonlight programme is creating the infrastructure that future lunar missions will rely on, laying the foundations for a sustainable presence beyond Earth🌍️ connectivity.esa.int/moonlight

🥵 Hot temperatures can lead to more wildfires🔥 How can satellite communications help emergency responders in these situations? www.esa.int/Applications...

#OTD in 1983, ECS‑1 launched aboard Ariane 1, Europe’s first step towards its own space-based communications 📶 From analogue signals to secure networks, the mission set the tone for Europe's present in space. Today, IRIS² builds on that legacy by reinforcing Europe’s autonomy in orbit 👁️ 🔐

Do you want to contribute to the future of mobile connectivity?📱 We are hiring a Procurement Coordinator for Direct-to-Device (D2D) projects at ESA. Interested? 🤔 👉️ jobs.esa.int/job/Noordwij...

Initially planned for one year, MDA Space's JoeySat marks its third year in orbit! 🥳 Built with support from @esa.int, @ukspaceagency.bsky.social and @eutelsat.bsky.social, JoeySat delivers flexible broadband anywhere with a 'hopping' beam, from busy summer festivals to airplanes💃 ✈️

How do you shape the future of satcom in space?🤔 You gather 300+ people from 30+ countries to connect, swap ideas and co-design how optical and quantum comms will work in orbit. Missed this year's ScyLight Conference? Here's the visual recap; maybe you'll join next year👀

🇪🇸We've officially wrapped up #ScyLight2026 in Tenerife, Spain! We are delighted to reveal that... ✨We welcomed 316 participants throughout the event ✨91% of you were from an ESA Member State, with 24% joining us from Spain.

Home to world-class research and a unique environment for advancing optical and quantum communications 👇 #ScyLight2026
