Italy's radar constellation for Earth observation is celebrating a record-breaking achievement in technological longevity. Today, the CSK2 satellite —the second spacecraft in the first-generation COSMO-SkyMed constellation— reached the historic milestone of 100,000 orbits around our planet.
Launched on December 9, 2007, from Vandenberg Air Force Base in California, the satellite operates at an altitude of approximately 620 kilometers. Traveling at speeds exceeding 27,000 kilometers per hour, it completes exactly 14.81 polar orbits per day, circling the Earth every 97 minutes.
Managed by the Italian Space Agency (ASI) in coordination with the Ministry of Defense, CSK2 is operating far beyond its original design life, which was initially estimated at 5 years and later extended to 7. Over nearly two decades of uninterrupted operations, the satellite has delivered millions of high-resolution radar images crucial for:
- Assessing damage from natural disasters like earthquakes and floods.
- Monitoring the security of critical infrastructure.
- Surveilling borders and maritime traffic.
- Studying the impacts of climate change.
- Tracking the status of natural resources and agriculture.
Reaching 100,000 orbits showcases the excellence of the Italian aerospace industry. The program's development was led by Thales Alenia Space and Telespazio, with e-GEOS serving as the exclusive distributor for the commercial data. Data continuity is currently ensured by the gradual deployment of the new Second Generation (CSG) satellites.
