The Thor-Ablestar, or Thor Able-Star, also known as Thor-Epsilon was an early American expendable launch system consisting of a PGM-17 Thor missile, with an Ablestar upper stage. It was a member of the Thor family of rockets, and was derived from the Thor-Able. Nineteen Thor-Ablestars were launched between 1960-65, of which four failed, and a fifth resulted in a partial failure, as only one of two payloads separated from the upper stage. The launch of a Transit satellite on 22 February 1961 was successful, but its companion Lofti satellite failed to separate from the second stage.

  • O Thor-Ablestar, ou Thor Able-Star, ou ainda Thor-Epsilon, foi um veículo de lançamento descartável de origem Norte americana. Esse modelo, consistia de um primeiro estágio baseado no míssil PGM-17 Thor, e um estágio superior Ablestar. Ele fazia parte da família de foguetes Thor,e foi uma derivação do Thor-Able. O segundo estágio Ablestar, era uma variantes mais potente do estágio de foguete Able original, que propiciava ao Thor-Ablestar, uma capacidade de carga útil bem maior que a do Thor-Able. Esse estágio, também incorporava a capacidade de reinício, permitindo vários acionamentos,para atingir ou alterar seu posicionamento para diferentes órbitas. Este foi o primeiro foguete desenvolvido com essa capacidade. (pt)

  • The Thor-Ablestar, or Thor Able-Star, also known as Thor-Epsilon was an early American expendable launch system consisting of a PGM-17 Thor missile, with an Ablestar upper stage. It was a member of the Thor family of rockets, and was derived from the Thor-Able. The Ablestar second stage was an enlarged version of the Able, which gave the Thor-Ablestar a greater payload capacity compared to the Thor-Able. It also incorporated restart capabilities, allowing a multiple-burn trajectory to be flown, further increasing payload, or allowing the rocket to reach different orbits. It was the first rocket to be developed with such a capability and development of the stage took a mere eight months. Nineteen Thor-Ablestars were launched between 1960-65, of which four failed, and a fifth resulted in a partial failure, as only one of two payloads separated from the upper stage. The first failure was the launch of Courier 1A, an experimental communications satellite, on 19 August 1960 when the first stage shut down 30 seconds earlier than planned and was destroyed by the Range Safety officer. On 30 November, another launch involving a Transit satellite failed in practically identical fashion. This episode nearly created an international incident as parts of the Thor landed in Cuba. Cuban leader Fidel Castro subsequently sold off the Thor's engine to the Soviets and the Chinese received its thrust vectors, which ended up proving valuable to the latter's development of a ballistic missile capability. To prevent this from happening again, future Thor Ablestar launches had their flight paths modified to avoid passing over Cuba. The launch of a Transit satellite on 22 February 1961 was successful, but its companion Lofti satellite failed to separate from the second stage. The third failure was the launch of several piggybacked satellites on 24 January 1962 when the second stage produced insufficient thrust to achieve orbital velocity. The fourth and final failure was the launch of an Anna geodetic satellite on 10 May 1962 when the second stage completely failed to ignite. Two versions were built; the Thor-Ablestar 1, with a DM-21 Thor, and an AJ-10-104 second stage engine, and the Thor-Ablestar 2, which had a DSV-2A Thor first stage, and an uprated AJ-10-104D engine on the second stage. Thor-Ablestar 1 launches occurred from LC-17 at Cape Canaveral, and Thor-Ablestar 2 rockets were launched from LC-75-1 at Point Arguello, which has since become part of Vandenberg Air Force Base and is now designated SLC-2.
