Early U.S. space shuttle concepts. Before the Apollo 11 Moon landing in 1969, NASA began studies of Space Shuttle designs as early as October 1968. The early studies were denoted "Phase A", and in June 1970, "Phase B", which were more detailed and specific.
The Space Shuttle external tank (ET) carried the propellant for the Space Shuttle Main Engines, and connected the orbiter vehicle with the solid rocket boosters. The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen.
Many of the themes and tone of the documentary regarded the normalization of travel to space using the Shuttle while giving only passing mention to the dangers. The Challenger disaster would dramatically curtail this belief and subsequent experience would show that the shuttle would not make space travel more accessible or affordable.
In the early 1990s, NASA engineers planning a crewed mission to Mars included a Shuttle-C design to launch six non reusable 80-ton segments to create two Mars ships in Earth orbit. After President George W. Bush called for the end of the Space Shuttle by 2010, these proposed configurations were put aside. [2] HLLV
The documentary was designed to get people excited about space, particularly about the Space Shuttle which was meant to make space easily accessible and cheap for everyone. Ultimately, this never came to be due to a string of design flaws such as the Space Shuttle tiles which were damaged or broken on multiple flights including STS-1.
When We Left Earth: The NASA Missions (or NASA's Greatest Missions: When We Left Earth in the UK) is a 2008 Discovery Channel HD documentary miniseries consisting of six episodes documenting American human spaceflight from the first Mercury flights and the Gemini program, to the Apollo program and its Moon missions and landings, to the Space Shuttle missions and the construction of the ...
The stalled plans for a U.S. space station evolved into the International Space Station and were formally initiated in 1983 by President Ronald Reagan, but the ISS suffered from long delays, design changes and cost over-runs [3] and forced the service life of the Space Shuttle to be extended several times until 2011 when it was finally retired ...
