The satellite designs also required that the Space Shuttle have a 4.6 by 18 m (15 by 60 ft) payload bay. NASA evaluated the F-1 and J-2 engines from the Saturn rockets , and determined that they were insufficient for the requirements of the Space Shuttle; in July 1971, it issued a contract to Rocketdyne to begin development on the RS-25 engine.
Agena and the Space Shuttle (1972 study) In the early 1970s Lockheed studied the use of Agena as a payload booster in the Space Shuttle payload bay. An Agena-C with an increased diameter was proposed, but never built. The Agena-2000 was intended as a modernized Agena, and would have been used on the Atlas V Light Evolved Expendable Launch ...
The combined space station and Air Force payload requirements were not sufficient to reach desired shuttle launch rates. Therefore, the plan was for all future U.S. space launches—space stations, Air Force, commercial satellites, and scientific research—to use only the Space Shuttle. Most other expendable boosters would be phased out.
The 5-segment SRB, which would have required little change to the current shuttle infrastructure, would have allowed the space shuttle to carry an additional 20,000 lb (9,100 kg) of payload in a 51.6°-inclination orbit, eliminate the dangerous "Return-to-Launch Site" (RTLS) and "Trans-Oceanic Abort" (TAL) modes, and, by using a so-called "dog ...
The mission lasted a total of 6 days, 2 hours, 3 minutes, and 51 seconds. STS-61-C was the last successful Space Shuttle flight before the Challenger disaster, which occurred on January 28, 1986, only 10 days after Columbia ' s return. Accordingly, commander Gibson later called the STS-61-C mission "The End of Innocence" for the Shuttle Program ...
The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by NASA (the National Aeronautics and Space Administration). Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. [ 1 ]
One area of Space Shuttle applications is an expanded crew. [35] Crews of up to eight have been flown in the Orbiter, but it could have held at least a crew of ten. [35] Various proposals for filling the payload bay with additional passengers were also made as early as 1979. [36]
The four currently active space station cargo vehicles. Clockwise from top left: Progress, Cargo Dragon 2, Cygnus, Tianzhou. A number of different spacecraft have been used to carry cargo to and from space stations .
