Flight preview
About this launch
Samos 2 was a first-generation US Air Force Samos-E1 reconnaissance satellite that scanned its film on board and radioed the images to the ground rather than returning a capsule. It reached a near-polar, sun-synchronous orbit and operated for roughly a month, though the pictures it sent back were of poor quality.
