USA 200 (SIGINT) 2008-010A 32706						in space
US intelligence-related satellite carrying an SBIRS (Space Based InfraRed) sensor and (probably) a commuications payload for use at northern latitudes. Also carries NASA's TWINS-B (Two Wide-angle Imaging Neutral-atom Spectrometers) detector for monitoring the magnetosphere. See also USA-184 (2006-27A/29249). Illustrations of the satellite published by NASA suggest it is spin-stabilised with a de-spun aerial array.

This mission also carried a number of small satellite ride share payloads but there is no indication of how or when they were released into independent orbit. Launch was by SpaceX on behalf of the USAF Rapid Capabilities Office. Landed Kennedy Space Center Shuttle Landing Facility 2019 Oct 27 at 07:51 UTC.. Element sets were not released by Space-Track so parameters are based on amateur observation, the final one was calculated by Nico Janssen from radio observations.

USA 280 (ZUMA?) 2018-001A 43098						Re-entered - 2018 Jan 8 Life <1 day
Classified US Government payload. Purpose, mission outcome and orbit unknown. Appears to have re-entered the Earth's atmosphere on the day of launch, an event that is unlikely to have been intended. SpaceX reported that the launch vehicle completed its mission as planned. The launch azimuth suggested it was heading for an inclination of about 50°. Originally scheduled for launch 2017 Nov 17 from Kennedy SC but launch delayed (and launch pad switched) because of an issue with a Falcon 9 payload shroud on another mission.
