List of Thor DM-21 Agena-B launches
Thor DM-21 Agena-B or just Thor-Agena was a series of orbital launch vehicles. The rockets used the Douglas-built Thor first stage and the Lockheed-built Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta rocket family. The first attempted launch of a Thor DM-21 Agena-B was in January 1959. The first successful launch was on 28 February 1959, launching Discoverer 17.[1]
