1 Jan 1981 Jahr - NASA invents reusable rockets

Beschreibung:

The first reusable spacecraft in orbit was the Space Shuttle in 1981. It failed to accomplish the goal of reducing launch costs that were below the price of replaceable launch systems, but during the 21st century interest in reusable launch systems has expanded and grown considerably. Several companies like SpaceX CEO Elon Musk has said that the costs of access to space could be reduced by as much as a hundred if we could figure out how to reuse rockets like airplanes. The Falcon 9 rocket has a reusable first stage and capsule for dragon flights with and expendable second stage. SpaceX has been developing a reusable second stage since the late 2010s which, if successful, could make possible the first fully reusable orbital launch vehicle during the 2020s.
