US efforts to use private sector rockets to launch spacecraft have been repeatedly delayed. Last-minute computer trouble nixed the planned launch of Boeing’s first astronaut flight Saturday.
Earlier on Saturday, a Japanese billionaire called off his plan to orbit the Moon because of uncertainty over the development of a mega rocket by SpaceX. Nasa is planning to use the rocket to send its astronauts to the Moon.
In China’s current mission, the lander is to use a mechanical arm and a drill to gather up to 2kg of surface and underground material for about two days.
An ascender atop the lander will then take the samples in a metal vacuum container back to another module that is orbiting the Moon. The container will be transferred to a re-entry capsule that is due to return to Earth in the deserts of China’s Inner Mongolia region about June 25.
Missions to the Moon’s far side are more difficult because it doesn’t face the Earth, requiring a relay satellite to maintain communications. The terrain is also more rugged, with fewer flat areas to land.
