Bluebell 2S (Sphere) was an Air Force calibration satellite launched piggy-back from Vandenberg AFB aboard an Atlas-SLV3 Agena-D rocket.
Due to the very low orbit, these satellites had very short orbital life times. Bluebell 2C decayed a day after launch and Bluebell 2S followed one week after launch.
