(KMOV) This is the Space-X reusable Grasshopper spacecraft. In it's most recent trial, featured here, the craft managed to hop more than 24 stories in the air, hover, then land safely.
Space-X officials say it is essential to keeping costs down to fully and rapidly develop reusable rockets. This initiative will transform space exploration.
This was the Grasshopper's fourth test flight. Each has doubled the altitude of the prior tests.
