China successfully landed a spacecraft on the moon’s surface late on Tuesday in the first mission to retrieve lunar surface samples in 40 years. Al Jazeera reports that the unmanned Chang’e-5 probe will attempt to collect two kilogrammes of samples in an area that has yet to be explored on an enormous lava plain known as Oceanus Procellarum, or “Ocean of Storms”. The lander vehicle is expected to start drilling into the ground with a robotic arm to collect the lunar material in about two days, according to state media. The samples will then be lifted into orbit and transferred to a return capsule for the return to Earth, where it is expected to land on land in China’s Inner Mongolia region. If the mission succeeds it will be the first time scientists have secured samples of lunar rocks since Russia (then the Soviet Union) brought material back in the 1970s.
