Discoverer II successfully reached orbit and took photos of Earth.

The capsule was never recovered.
Thor-Agena was a series of orbital launch vehicles. The rockets used Thor first stages and Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta rocket family.
