Gemini 4 would be the first multi-day space flight by the United States, designed to show that it was possible for humans to remain in space for extended lengths of time. The four-day, 66- orbit flight [ 6 ] would approach but not break the five-day record set by the Soviet Vostok 5 in June 1963.
Valery Bykovsky flew solo for 4 days, 23 hours in Vostok 5 from 14 to 19 June 1963. [38] The flight set a space endurance record which was broken in 1965 by the (non-solo) Gemini 5 flight. The Apollo program included long solo spaceflight, and during the Apollo 16 mission, Ken Mattingly orbited solo around the Moon for more than 3 days and 9 hours.

The Gemini 11 mission attempted in 1966 to produce artificial gravity by rotating the capsule around the Agena Target Vehicle to which it was attached by a 36-meter tether. They were able to generate a small amount of artificial gravity, about 0.00015 g , by firing their side thrusters to slowly rotate the combined craft like a slow-motion pair ...
The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
The Shapiro time delay effect, or gravitational time delay effect, is one of the four classic Solar System tests of general relativity. Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.

Skylab 4 (also SL-4 and SLM-3 [2]) was the third crewed Skylab mission and placed the third and final crew aboard the first American space station.. The mission began on November 16, 1973, with the launch of Gerald P. Carr, Edward Gibson, and William R. Pogue in an Apollo command and service module on a Saturn IB rocket from the Kennedy Space Center, Florida, [3] and lasted 84 days, one hour ...
