About: Thor-Ablestar

An Entity of Type: rocket, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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-Ablestar were launched between 1960–1965, 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.

  • 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-Ablestar were launched between 1960–1965, 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. War was threatened. 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. On 29 June 1961, a Thor-Ablestar successfully inserted a Transit-4A into orbit, but two hours later the Ablestar exploded for unknown reasons into hundreds of pieces, which remained in orbit. The third launch failure occurred on 24 January 1962 when the second stage produced insufficient thrust to achieve orbital velocity for several piggybacked satellites. 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 Vandenberg Space Force Base and is now designated SLC-2. (en)
  • O Thor-Ablestar, ou Thor-Able-Star, também conhecido como Thor-Epsilon foi um dos primeiros veículo de lançamento descartável estadunidense que consistia em um míssil PGM-17 Thor, com um estágio superior Ablestar. Era um membro da família de foguetes Thor e era derivado do Thor-Able. O segundo estágio do Ablestar foi uma versão ampliada do Able, que deu ao Thor-Ablestar uma maior capacidade de carga em comparação com o Thor-Able. Ele também incorporou recursos de reinicialização, permitindo que uma trajetória de queima múltiplas seja feita, aumentando ainda mais a carga útil ou permitindo que o foguete alcance diferentes órbitas. Foi o primeiro foguete a ser desenvolvido com essa capacidade e o desenvolvimento do palco levou apenas oito meses. Dezenove Thor-Ablestar foram lançados entre 1960-1965, dos quais quatro falharam, e um quinto resultou em uma falha parcial, já que apenas uma das duas cargas úteis se separou do estágio superior. A primeira falha foi o lançamento do Courier 1A, um satélite de comunicação experimental, em 19 de agosto de 1960, quando o primeiro estágio foi desligado 30 segundos antes do planejado e foi destruído pelo oficial da Range Safety. Em 30 de novembro, outro lançamento envolvendo um satélite Transit falhou de maneira praticamente idêntica. Este episódio quase criou um incidente internacional quando partes do Thor aterrissaram em Cuba. O líder cubano Fidel Castro posteriormente vendeu o motor do Thor para os soviéticos e os chineses receberam seus vetores de empuxo, que acabaram se mostrando valiosos para o desenvolvimento de uma capacidade de míssil balístico. Para evitar que isso aconteça novamente, os futuros lançamentos de Thor Ablestar tiveram suas rotas de vôo modificadas para evitar a passagem sobre Cuba. O lançamento de um satélite Transit em 22 de fevereiro de 1961 foi bem-sucedido, mas seu satélite companheiro Lofti não conseguiu se separar do segundo estágio. Em 29 de junho de 1961, um inseriu com sucesso um Transit-4A em órbita, mas duas horas depois o Ablestar explodiu por razões desconhecidas em centenas de pedaços, que permaneceram em órbita. A terceira falha de lançamento ocorreu em 24 de janeiro de 1962, quando o segundo estágio produziu empuxo insuficiente para atingir a velocidade orbital de vários satélites acoplados. A quarta e última falha foi o lançamento de um satélite geodésico Anna em 10 de maio de 1962, quando o segundo estágio falhou completamente em acender. Duas versões foram construídas; o Thor-Ablestar 1, com um DM-21 Thor e um motor de segundo estágio AJ-10-104, e o Thor-Ablestar 2, que tem um DSV-2A Thor de primeiro estágio e um motor AJ-10-104D aprimorado no segundo estágio. Lançamentos de Thor-Ablestar 1 ocorreram de LC-17 no Cabo Canaveral, e os foguetes Thor-Ablestar 2 foram lançados de LC-75-1 em Point Arguello, que desde então se tornou parte da Base da Força Aérea de Vandenberg e agora é designado SLC -2.
