  • American military naval signals reconnaisance satellite. 7 launches, 1971.03.21 (Jumpseat 1) to 1983.07.31 (Jumpseat 7). Jumpseat signals intelligence satellites were launched by Titan 3B or 34B into highly elliptic Molniya-type orbits.

Jumpseat-2.

  • American military naval signals reconnaisance satellite. 2 launches, 2006.06.25 (USA 200) to 2008.03.13 (USA 200).

Jung.

  • Jung German expert in chemical warfare during World War II.

Jungert.

  • Jungert, Wilhelm German engineer in WW2, member of the German rocket team, went to America after the first group.

Junkers 'Junior'.

  • German manned rocketplane. Flown 1936. Early German rocketplane.

Juno.

Juno.

Juno 1 (retrospectively).

  • Alternate designation for Jupiter C rocket stage.

Juno I.

  • Alternate designation for Jupiter C orbital launch vehicle.

Juno II.

  • American orbital launch vehicle. Satellite launcher derived from Jupiter IRBM. Basic 4 stage vehicle consisted of 1 x Jupiter + 1 x Cluster stage 2 + 1 x Cluster stage 3 + 1 x RTV Motor

Juno II (3).

  • American intermediate range ballistic missile. Three stage version consisting of 1 x Jupiter + 1 x Cluster stage 2 + 1 x Cluster stage 3

Juno II-3.

  • Solid rocket stage. 22.00 kN (4,946 lbf) thrust. Mass 100 kg (220 lb).

Juno V.

  • Alternate designation for Saturn I orbital launch vehicle.

Juno V-A.

  • American orbital launch vehicle. By 1958 the Super-Jupiter was called Juno V and the 4 E-1 engines were abandoned in favor of clustering 8 Jupiter IRBM engines below existing Redstone/Jupiter tankage. The A version had a Titan I ICBM as the upper stages. Masses, payload estimated.

Juno V-B.

  • American orbital launch vehicle. A proposed version of the Juno V for lunar and planetary missions used a Titan I ICBM first stage and a Centaur high-energy third stage atop the basic Juno V cluster. Masses, payload estimated.

Jupiter.

  • The Jupiter IRBM was developed for the US Army. By the time development was complete, the mission and the missile was assigned to the US Air Force, which had its own nearly identical missile, the Thor. Jupiters were stationed in Turkey and Italy in the early 1960's, but withdrawn in secret exchange for the withdrawal of Soviet R-5 missiles from Cuba. The Jupiter was used as the first stage of the relatively unsuccessful Juno II launch vehicle, and proposed for the Juno III and Juno IV. Jupiter tooling and engines were used to build the much larger Juno V / Saturn I launch vehicle.

Jupiter.

  • Lox/Kerosene propellant rocket stage. Loaded/empty mass 54,431/5,443 kg. Thrust 758.71 kN. Vacuum specific impulse 282 seconds.

Jupiter A.

  • American orbital launch vehicle. The Jupiter A was a modified Redstone missile fitted with Jupiter inertial navigation and control system elements. It also tested Hydyne fuel and other engine modifications for the Jupiter C re-entry vehicle test booster.

Jupiter C.

  • American orbital launch vehicle. Re-entry vehicle test booster and satellite launcher derived from Redstone missile. The Jupiter A version of the Redstone missile was modified with upper stages to test Jupiter re-entry vehicle configurations. Von Braun's team was ordered to ballast the upper stage with sand to prevent any 'inadvertent' artificial satellites from stealing thunder from the official Vanguard program. Korolev's R-7 orbited the first earth satellite instead. The Jupiter C was retroactively named the 'Juno I' by Von Braun's team.

Jupiter C.

  • Lox/Hydyne propellant rocket stage. Loaded/empty mass 28,430/3,890 kg. Thrust 416.18 kN. Vacuum specific impulse 265 seconds. Redstone missile, stretched, modified with different propellants to serve as first stage of IRBM nose cone/orbital test vehicle.

Jupiter C Juno I.

  • American short range ballistic missile. Four stage orbital launch version consisting of 1 x Redstone + 1 x Cluster stage 2 + 1 x Cluster stage 3 + 1 x RTV Motor. The fourth stage allowed the Explorer payload to be placed into orbit.

Jupiter C-2.

  • Solid rocket stage. 80.00 kN (17,985 lbf) thrust. Mass 500 kg (1,102 lb).

Jupiter Cluster.

  • Lox/Kerosene propellant rocket stage. Loaded/empty mass 226,716/27,205 kg. Thrust 3,034.29 kN. Vacuum specific impulse 282 seconds. Masses estimated (cluster of four Jupiter IRBM stages)

Jupiter Mercury.

  • American intermediate range ballistic missile. Version of Jupiter IRBM designed for launch of Mercury manned capsules on long suborbital flights. Cancelled early in the programme, with the decision being to proceed from Mercury Redstone suborbital flights directly to Mercury Atlas orbital missions.

Jupiter nose cone.

  • American re-entry vehicle technology satellite. One launch, 1964.01.29, Saturn 5. Launch vehicle test.

Just.

  • Just German rocket engineer in WW2; later worked in France at LRBA on radio beam guidance in the automated control loop department 1947-1952.
