Are you interested in procurement opportunities from #EUSST? A new call for tenders on secure data sharing with Quantum Keys over long distances, using space-based facilities, has been recently launched.   More info ➡️ eusst.eu/about-us/procu… #EUSpace #EUtenders

On 26 May, there will be a session on #EUSST, showcasing its Collision Avoidance and Re-entry Analysis services and how it has evolved over ten years. If you are interested, register now! ⬇️ #EUSpace @EU_HaDEA @CNES @aee_gob @ASI_spazio @defis_eu

#EUSST provides three SST services: Collision Avoidance, Re-entry Analysis and Fragmentation Analysis. The Re-entry Analysis service provides risk assessments of uncontrolled re-entries of space objects into the Earth’s atmosphere: eusst.eu/services #EUSpace

Are you interested in procurement opportunities from #EUSST? A new call for tenders on R&D on the preparation of a responsive architecture for Space Traffic Management activities has been recently launched.   More info ➡️ eusst.eu/about-us/procu… #EUSpace #EUtenders

The #EUSST Processing function coordinates the data sharing between the different Operations Centres via a common database and processes hundreds of thousands of daily measurements from the sensors contributing to EU SST. Learn more about us: eusst.eu/about-us #EUSpace

Are you interested in procurement opportunities from #EUSST? Three new calls for tenders have been published on these topics: 📌Debris population 📌Optimising radar observations 📌SBSS More info: eusst.eu/about-us/procu… #EUSpace #EUtenders @defis_eu @EU_HaDEA @DLR_SpaceAgency

#EUSST provides three SST services: Collision Avoidance, Re-entry Analysis and Fragmentation Analysis. The Collision Avoidance service provides risk assessments of potential collisions between space objects and recommendations on how to mitigate the risk: eusst.eu/services

How does #EUSST improve our lives? EU SST helps protect the safety of economies, societies and citizens, which rely on space-based applications such as: 🗺navigation 📱communication 🌍Earth observation More about us here ➡️ eusst.eu/about-us #EUSpace @defis_eu @EU_HaDEA

The correct answer is: b. In 2025, more than 30,000 close approaches for EU SST-registered satellites were detected in the three orbital regimes. Thank you for participating! Learn more about #EUSST here: eusst.eu/about-us #EUSpace
