The Moon did not offer any favourable conditions for Man to stay there even for a minute. It did not have air to breathe or water to drink. Neither did it have an atmosphere to block the harmful radiations. Moreover, the Moon had extreme climatic conditions. Despite these adverse conditions, NASA aimed to send Man to the Moon.
This project was named Apollo. Project Apollo was designed to land humans on the Moon and bring them back safely. They first had to aim for a precise point in space, or else the Moon would be missed altogether. The spacecraft had to travel 3,84,400 kilometres to reach the Moon.
The Apollo programme consisted of a large number of unmanned test missions and eleven manned missions. Out of the manned missions, two were Earth orbiting missions. It had two lunar orbiting missions, one lunar swing-by and the others were moon landing missions.
