In September, Bolden announced the design of a new Space Launch System -- a heavy-lift rocket that will take our astronauts farther into space than ever before, create high-quality jobs here at home, and provide the cornerstone for America's future human space exploration efforts.hose selected also will be among the first to pioneer a new generation of commercial launch vehicles and travel aboard a new heavy-lift rocket to distant destinations in deep space. Qualified individuals can apply to become an astronaut through the federal government's USAJobs.gov website.
Astronauts are by far the fastest traveling humans with the earth as a stationary reference point. One might think the Apollo missions to the moon are the fastest traveling humans, but the speed of that spacecraft was only about 6,300 miles per hour. In fact, an orbiting space shuttle is much faster at 17,600 miles per hour. This is the fastest any man has reached. Although it seems very fast to us, this speed is 0.026% of the speed of light. For unassisted speed using Usain Bolt's time in the 100 meter, his top speed is 23.3 miles per hour (10.4 m/s).
