Moon landing imminent for China’s Chang’e 5 on its mission to collect lunar samples
- Lunar target zone has different, more recent geology than samples collected by American and Soviet missions decades ago
- Orbiter continues circling the moon until lander and ascending craft return from moon’s surface
The lander, together with an ascending vehicle, separated from the orbiter early on Monday morning using “precision manoeuvring” by operators on Earth, and will make a soft landing “at an appropriate time”, CCTV said.
“All systems on the Chang’e 5 are working in good condition, and the communication with and control from the ground station are going smoothly,” it said.
The lander will aim for the volcanic Mons Rümker in the northwest area called Oceanus Procellarum, or “Ocean of Storms”, on the near side of the moon.
This area of relatively recent volcanic activities – about 1.2 billion years ago – has a younger rock surface and these samples are expected to contain information about the more recent history of the moon compared with previous lunar samples collected by Americans and Soviets from older regions.
The Chang’e 5 will drill as deep as 2 metres (6.6 feet) for rock cores, and also take samples from the surface using a robotic arm, with the goal of collecting 2kg (4.4-pound) samples in its protective capsules over two weeks.
