The Saturn V rocket was used by NASA between 1967 and 1973. It is a 'human rated expendable rocket', which means that it is safe to use for human spaceflight. The rocket was developed to support the Apollo program, to fly humans to the moon, and was later used to launch Skylab.

Governments and space agencies across the world have announced plans for future space exploration:

• First animals in space:

The Mercury missions was NASA's first human spaceflight program, from 1958 to 1963. There were 20 unmanned flights (some which sent animals into space), and six successful flights by astronauts.

The Gemini missions was NASA's human spaceflight program in the early 1960s. The Gemini missions came after the Mercury missions, and before the Apollo missions. Each Gemini spacecraft could carry two astronauts, and 10 spacecraft were launched during the Space Race.
