Technology.
Rocketry, propulsion, materials, energy, optics. The historical record.
- —ENERGY
Zero-point energy concepts
Theoretical lowest-energy state of a quantum mechanical system. Subject of speculative engineering proposals in the late twentieth century, particularly through the SRI work of Hal Puthoff and Bernhard Haisch. No reproducible energy-extraction device has been demonstrated.
- 1998OTHER
International Space Station
Modular space station in low Earth orbit, assembled by 15 nations. Continuously inhabited since November 2, 2000. The largest human-made structure in space.
- 1981MATERIALS
F-117 Nighthawk
First operational stealth aircraft. Flown by the United States Air Force from 1983 to 2008. Public existence acknowledged 10 November 1988. Faceted radar-cross-section design directly informed by the 1962 Soviet paper "Method of Edge Waves in the Physical Theory of Diffraction" by Pyotr Ufimtsev.
- 1977OTHER
Voyager Program
Two robotic spacecraft launched in 1977. Voyager 1 is now 24 billion kilometers from Earth — the most distant human-made object in existence. Both carry the Golden Record.
- 1972ROCKETRY
Space Shuttle Program
NASA's partially reusable crewed launch system. 135 flights, 1981–2011. Two catastrophic failures — Challenger (1986) and Columbia (2003) — killed fourteen astronauts. Launched Hubble and assembled the ISS.
- 1967ROCKETRY
Saturn V
Three-stage liquid-fueled super heavy-lift launch vehicle developed by NASA Marshall Space Flight Center for the Apollo program. Operational from 1967 to 1973. The largest rocket to reach orbit until the Starship Heavy in the 2020s.
- 1964ROCKETRY
SR-71 Blackbird
Lockheed Mach 3+ strategic reconnaissance aircraft. Developed by Skunk Works under Clarence Johnson from the A-12 platform. Flew operationally with the United States Air Force from 1966 to 1998. The aircraft remains the fastest air-breathing manned aircraft on record.
- 1961ROCKETRY
Project Gemini
The second US human spaceflight program. Ten crewed missions, 1965–1966. Developed orbital rendezvous, docking, and long-duration spaceflight techniques essential for Apollo.
- 1961ROCKETRY
Project Apollo
The US lunar landing program. Twelve crewed landings, 1969–1972. Twelve humans walked on the Moon. The most complex engineering undertaking in human history at the time of its execution.
- 1961ROCKETRY
Vostok Program
Soviet crewed spaceflight program, 1961–1963. Six flights, six cosmonauts. First human in space (Gagarin, 1961), first woman in space (Tereshkova, 1963). Cosmonauts ejected at altitude and parachuted separately — a detail the Soviets classified for three years.
- 1958ROCKETRY
Project Mercury
The first US human spaceflight program. Six crewed flights, 1961–1963. Demonstrated that humans could survive and function in space.
- 1944ROCKETRY
V-2 Rocket
Worlds first long-range guided ballistic missile. Developed by Wernher von Braun and the Peenemunde team for Nazi Germany. Captured V-2 hardware became the basis for the postwar United States and Soviet rocket programs through Operation Paperclip and Operation Osoaviakhim.
