The Agena Target Vehicle (/əˈdʒiːnə/; ATV), also known as Gemini-Agena Target Vehicle (GATV) was an uncrewed spacecraft used by NASA during its Gemini program to develop and practice orbital space rendezvous and docking techniques, and to perform large orbital changes, in preparation for the Apollo program lunar missions.The spacecraft was based on Lockheed Aircraft's Agena-D upper stage rocket, fitted with a docking target manufactured by McDonnell Aircraft. The name 'Agena' derived from the star Beta Centauri, also known as Agena.The combined spacecraft was a 26-foot (7.92 m)-long cylinder with a diameter of 5 feet (1.52 m), placed into low Earth orbit with the Atlas-Agena launch vehicle. It carried about 14,021 to 14,054 pounds (6,360 to 6,375 kg) of propellant and gas at launch, and ha

  • アジェナ標的機(アジェナひょうてきき、Agena target vehicle,ATV)はアメリカ合衆国のジェミニ計画で用いられた宇宙船。無人機であり、軌道上におけるランデブーやドッキングの技術開発に用いられた。 元々、アジェナは偵察衛星として開発されていたものであった。これにドッキング・ユニットを増設し、軌道上での技術試験衛星として用いたものである。ATVはケープカナベラル空軍基地LC-14発射台よりアトラス・ロケットを用いて打ち上げられる。 ATVとの軌道上ランデブー/ドッキングのために、ATVの打上げの約90分後(概ね軌道周回時間)にジェミニ宇宙船はLC-19発射台より打ち上げられた。ATVとの軌道上での試験としては、ランデブー/ドッキングの一環として、以下のようなものが行なわれた。 * ドッキング状態における姿勢制御。(ジェミニ8号では、ジェミニ宇宙船のスラスタの不調により制御に失敗、途中中止となった) * 船外活動の研究。 * ATVのエンジンを用い、高軌道への遷移。 * (Gravity-gradient stabilization)による姿勢制御(テザー推進)の試験。ATVとジェミニ宇宙船を30m離れてロープで結び、重力の影響を観察。 ATVは試験終了後、比較的短期間に大気圏に突入している。 (ja)

  • Das Gemini Agena Target Vehicle (GATV) war ein orbitaler Zielflugkörper, der von der NASA während des Gemini-Programmes zur Erprobung von Rendezvous-Manövern eingesetzt wurde. Die Fähigkeit zum Rendezvous im All war für das folgende Apollo-Programm wichtig, um während des Fluges zum Mond die Mondlandefähre mit der Kommandokapsel koppeln zu können. Die hierfür notwendigen Techniken wurden im Gemini-Programm erforscht und erlernt. Insgesamt wurden sieben GATVs gestartet. (de)

  • L'Agena Target Vehicle venne disegnato e concepito onde consentire la manovra rendezvous e di aggancio di due veicoli spaziali in orbita - manovre da eseguire in preparazione del programma Apollo che aveva il fine di portare l'uomo sulla Luna. Un Agena L'Agena vista dal Gemini 8 Gli astronauti del programma Gemini poterono dunque volare in uno stato stabile di aggancio dei due veicoli ed eseguire molteplici esperimenti: (it)
  • Agena Target Vehicle – zmodyfikowana wersja stopnia rakietowego Agena D (podobne wykorzystywano do wystrzelenia sond kosmicznych Ranger i Mariner). Był to górny stopień rakiety nośnej Atlas Agena D, którym – po umieszczeniu na orbicie – mogli sterować kontrolerzy z Ziemi albo załoga statku Gemini. Orientację Ageny można było kontrolować za pomocą silniczków na sprężony azot, umieszczonych w tylnej części rakiety. (pl)
  • O Veículo alvo Agena (em inglês Agena Target Vehicle - ATV), era uma espaçonave usada pela NASA durante seu programa Gemini para desenvolver e praticar técnicas de encaixe e encontro no espaço orbital e para realizar mudanças orbitais, em preparação para as missões lunares do programa Apollo. A sonda foi baseado no foguete Agena-D da Lockheed Aircraft, equipada com um alvo de encaixe fabricado pela McDonnell. O nome 'Agena' deriva da estrela Beta Centauri, também conhecida como Agena. A espaçonave combinada era um cilindro de 26 pés (7,92 m) de comprimento com um diâmetro de 5 pés (1,52 m), colocado em órbita baixa da Terra com o veículo de lançamento Atlas-Agena. Ele carregava aproximadamente 14 021 a 14 054 libras (6 360 a 6 375 kg) de propelente e gás no lançamento, e tinha uma massa br (pt)
