Next China lunar lander aimed for farside south pole

The competition heats up: China announced plans today to send its next lunar lander, Chang’e 4, to the Moon’s farside south pole in 2018.

The lander of Chang’e-4 will be equipped with descent and terrain cameras, and the rover will be equipped with a panoramic camera, he said. Like China’s first lunar rover Yutu, or Jade Rabbit, carried by Chang’e-3, the rover of Chang’e-4 will carry subsurface penetrating radar to detect the near surface structure of the moon, and an infrared spectrometer to analyze the chemical composition of lunar samples.

But unlike Chang’e-3, the new lander will be equipped with an important scientific payload especially designed for the far side of the moon: a low-frequency radio spectrometer. “Since the far side of the moon is shielded from electromagnetic interference from the Earth, it’s an ideal place to research the space environment and solar bursts, and the probe can ‘listen’ to the deeper reaches of the cosmos,” Liu said.

The U.S. had been in the lead in the land rush to gain dominance in the possibly water-rich lunar south pole. We apparently have lost this lead with decision of President Obama and Congress to focus elsewhere, either the asteroids or Mars.

China outlines the plans for its next two unmanned lunar probes, with the second targeted as a 2017 sample return mission.

The new mission planned for 2017 would mark the third and final phase of China’s robotic lunar exploration program and pave the way for possibly landing an astronaut on the moon after 2020.

As I mentioned last night, the soft landing on Saturday demonstrated they are developing the technology to land a manned vehicle safely on the Moon. To return samples safely would demonstrate they are developing the technology to return that manned vehicle safely as well.

Update: Yutu did not land anywhere near its planned landing location.

China had originally publicized a location in the Sinus Iridum (Bay of Rainbows) — a level area thoroughly surveyed by a previous Chinese mission — as the landing spot. Local media even stated that Chang’e 3 landed there. But Chinese scientists have since confirmed that the spacecraft landed slightly to the east, in the northern part of Mare Imbrium (Sea of Rains).

It is unclear whether this was a late change or the result of a technical problem.
