Bluebell 2S (Sphere) was an Air Force calibration satellite launched piggy-back from Vandenberg AFB aboard an Atlas-SLV3 Agena-D rocket.
Two Bluebell satellites were on this launch: one in shape of a sphere, the other in the shape of a cylinder (Bluebell 2C). The prime payload was the KH-7 25 reconaissance satellite.
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.
