The Space Shuttle was the highlight of NASA’s Space Transport System’s reusability. Six shuttles were built, but only five ever went to orbit. STS Enterprise was used only for preliminary test flights and training.
The Space Transport System (also known as the Space Shuttle) revolutionized American spaceflight. Its design and development were greenlighted by President Richard Nixon in 1969, with flights beginning in the early 1980s.
Known as NASA’s SpaceX Demo-2 test flight, which is targeted for lift off at 3:22 p.m. EDT Saturday, May 30, this mission will send NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station as part of the agency’s Commercial Crew Program.
In the first two parts, we discussed Sputnik I, the first satellite ever put into orbit, and Sputnik II, the follow-on mission to Sputnik I. In this last part, we’ll examine Explorer I, the first U.S. satellite in space.
Sustaining human life in outer space is a challenging undertaking. Despite about 200,000 years on the planet in our current, highly-evolved form, humans have only within the last 60 or so years figured out how to go into space without getting killed.
In part IV, we looked at the need to protect spacecraft from the harsh outer space environment while maintaining comfortable temperatures for crews. In this final part, we’ll explore the challenges surrounding keeping human spaceflight crews fed and hydrated during their missions.
