Shuttle-C
The Shuttle-C was a study by NASA to turn the Space Shuttle launch stack into a dedicated uncrewed cargo launcher. The Space Shuttle external tank and Space Shuttle Solid Rocket Boosters (SRBs) would be combined with a cargo module to take the place of the Shuttle orbiter and include the main engines. Various Shuttle-C concepts were investigated between 1984 and 1995. The Shuttle-C concept would theoretically cut development costs for a heavy launch vehicle by re-using technology developed for the shuttle program. End-of-life and Space Shuttle hardware would also have been used. One proposal even involved converting '' Columbia'' or ''Enterprise'' into a single-use cargo launcher. Before the loss of Space Shuttle ''Challenger'', NASA had expected about 24 shuttle flights a year. In the aftermath of the ''Challenger'' incident, it became clear that this launch rate was not feasible for a variety of reasons. With the Shuttle-C, it was thought that the lower maintenance and safety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Lunar Resources Exploration Concept
The International Lunar Resources Exploration Concept (ILREC) was a proposed mission architecture under President George H. W. Bush's Space Exploration Initiative (SEI) by Kent Joosten, an engineer at Johnson Space Center. The plan would have used the help of international partners, mainly the Soviet Union, to assemble a lunar base and sustainable lunar transportation service. Space Exploration Initiative On July 20, 1989, the 20th anniversary of the Apollo 11 Moon landing, George H. W. Bush — then President of the United States — announced plans for what came to be known as the Space Exploration Initiative (SEI). In a speech on the steps of the National Air and Space Museum he described plans calling for constructing Space Station Freedom, sending humans back to the Moon "to stay" and ultimately sending astronauts to explore Mars. He proposed not a 10-year Apollo-style plan, but a long-range continuing commitment based on the three above elements, ending with "a journey ...

Shuttle-Derived Heavy Lift Launch Vehicle
The Shuttle-Derived Heavy Lift Launch Vehicle ("HLV") was an alternate super heavy-lift launch vehicle proposal for the NASA Constellation program. It was first presented to the Augustine Commission on 17 June 2009. Based on the Shuttle-C concept which has been the subject of various studies since the 1980s, the HLV was a Shuttle-Derived Launch Vehicle (SDLV) that proposed to replace the winged Orbiter from the Space Shuttle stack with a side-mounted payload carrier. The Space Shuttle's External Tank (ET) and four-segment Shuttle Solid Rocket Boosters (SRBs) would have remained the same. According to initial estimates, the HLV could have been developed within 4 years for about US$6.6 billion, which was about 20% of the costs estimated for the Ares I and Ares V vehicle development. Origin An uncrewed side-mounted concept of the Space Shuttle named Shuttle-C was investigated between 1984 and 1995. The Shuttle-C cargo only option was not funded in the 1980s and 1990s due to NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Shuttle Challenger Disaster
On January 28, 1986, the broke apart 73 seconds into its flight, killing all seven crew members aboard. The spacecraft disintegrated above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39a.m. Eastern Time Zone, EST (16:39 Coordinated Universal Time, UTC). It was the first fatal accident involving an List of space programs of the United States, American spacecraft in flight. The mission, designated STS-51-L, was the tenth flight for the Space Shuttle orbiter, orbiter and the twenty-fifth flight of the Space Shuttle fleet. The crew was scheduled to deploy a communications satellite and study Halley's Comet while they were in orbit, in addition to taking school teacher Christa McAuliffe into space. The latter resulted in a higher than usual media interest and coverage of the mission; the launch and subsequent disaster were seen live in many schools across the United States. The cause of the disaster was the failure of the two O-ring seals in a joint in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnum (rocket)
The Magnum was a large Super heavy-lift launch vehicle, super-heavy-lift rocket designed by NASA's Marshall Space Flight Center during the mid-1990s. The Magnum, which never made it past the preliminary design phase, would have been a launcher some 96 meters (315 feet) tall, on the scale of the Saturn V and was originally designed to carry a Exploration of Mars, human expedition to Mars. It was to have used two strap-on side boosters, similar to the Space Shuttle Solid Rocket Boosters (SRBs), but using liquid fuel instead. Some designs had the strap-on boosters using wings and jet engines, which would enable them to fly back to the launch area after they were jettisoned in flight. The Magnum was designed to carry around 80 tons of payload into low Earth orbit (LEO).
