Kleos Space S. A advised its fourth cluster of four satellites, the Observer Mission (KSF3), is ready to be shipped to the launch site after successfully completing environmental test phases. The Observer Mission satellites have successfully completed all System Assembly and Integration and Test (SAIT) activities, followed by system level electrical and mechanical functionality verification, including environmental testing of the satellites. Each system has been subjected to vibration, thermal, and electromagnetic compatibility (EMC) tests, ensuring functionality of the cluster after launch for the duration of the mission.

The Observer Mission satellites will be deployed into a Sun Synchronous orbit from Cape Canaveral Space Force Station in Florida on the Transporter-6 SpaceX mission currently scheduled for Fourth Quarter 2022 and will expand Kleos' data collection capacity by up to an additional 119 million km² per day.
