What rocket was the world's first long-range guided ballistic missile, and upon which the fictional spaceship Orbit Jet in the 1954 TV series "Rocky Jones, Space Ranger" was based on ?
Orbit Jet The Orbit Jet was a fictional spaceship in the 1954 TV series "Rocky Jones, Space Ranger". It strongly resembled a V-2 rocket in overall form, with a very prominent exhaust plume when flying, but had wings in addition to tailfins (even its radio callsign, "XV-2" relates it to that seminal World War II design). There were references in the dialog to the engines being "atomic". The "Orbit Jet" had a crew of two (pilot and copilot), but often had three or four others on board depending on the mission and destination. It often flew from Earth to inhabited moons of Jupiter and Saturn, which it seemed to reach in hours or days of time within the story.
J-2X The J-2X is a liquid-fueled cryogenic rocket engine that was planned for use on the Ares rockets of NASA's Constellation program, and later the Space Launch System. Built in the United States by Aerojet Rocketdyne (formerly, Pratt & Whitney Rocketdyne), the J-2X burns cryogenic liquid hydrogen and liquid oxygen propellants, with each engine producing 1307 kN of thrust in vacuum at a specific impulse ("I") of 448 isp . The engine's mass is approximately 2,470 kg (5,450 Lb), significantly heavier than its predecessors.
