Kleos Space S.A. announced that it has been informed by its launch services provider Spaceflight Inc., who is contracted to deploy the Kleos Patrol Mission (KSF2) satellites into an sun synchronous orbit, that after integration of the satellites onto its Sherpa vehicle for the SpaceX Transporter-3 mission, their technicians discovered a leak from the propulsion system of the Sherpa. This incident resulted in an inability for Spaceflight Inc. to launch any of the satellites manifest on the Sherpa for the SpaceX Transporter-3 launch as planned for January 2022, including the Kleos Patrol Mission satellites. Spaceflight Inc. has confirmed the four Kleos satellites are safe and were not damaged by the leak. Spaceflight Inc. are currently investigating all alternatives for remanifesting the four Kleos satellites as well as the satellites from six other companies impacted by this issue on another launch with the minimum of delay. The option to launch on the SpaceX Transporter-3 launch through another launch service provider was fully investigated, but due to the short time frame, such a change was not possible. The new launch date will be communicated to the market once confirmed with Spaceflight Inc. The Kleos Observer Mission (KSF3) is on track for mid-22 launch and is unaffected by the Patrol Mission delay.
