China’s lander releases data, high-resolution images of the Moon

The data was collected over a period of 12 lunar "days."

A little more than one year ago, China's Chang'e 4 spacecraft landed on the far side of the Moon. In doing so, it became the first-ever vehicle to make a soft landing on the side of the Moon facing away from Earth.

To mark the one-year anniversary, China released a batch of scientific data and images captured by five scientific payloads aboard the 1.2-ton spacecraft and its small Yutu 2 rover. Since the landing, the rover has driven a little more than 350 meters across the Moon's surface, studying rock formations and taking additional photos. The data was collected over a period of 12 lunar "days," or most of the last year.

The lander itself carried an excellent camera to image its surroundings. Extra sharp with a good color balance, the Terrain Camera was mounted at the top of the lander, with the ability to rotate 360 degrees. Before it died at the end of the first lunar day, this TCAM returned detailed images of the Moon. A helpful Twitter user in France, Techniques Spatiales, converted the camera's imagery into .png files, which can be found here.

The Chang'e 4 spacecraft landed in the South Pole-Aitken basin in the southern hemisphere of the far side of the Moon. The lander and rover have produced the best in situ data of the unexplored far side of the Moon to date, including radar and radiation measurements of the largely unexplored environment.

After this success, China intends to launch the Chang'e 5 mission late this year. It has the ambitious goal of returning as much as 2kg of lunar regolith to Earth, and is scheduled to launch on a Long March 5 rocket near the end of this year. It would be by far the most complicated robotic mission China has ever attempted and if successful would return the first lunar samples to Earth since the Soviet Luna 24 mission in 1976.

China's Chang'e-4 probe resumes work for 14th lunar day

The lander and rover of the Chang'e-4 probe have resumed work for the 14th lunar day on the far side of the moon after "sleeping" during the extremely cold night.

Both the lander and the rover are in normal working order, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

The Chang'e-4 probe, launched on Dec. 8, 2018, made the first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3, 2019.

The rover Yutu-2, or Jade Rabbit-2, has worked much longer than its three-month design life, becoming the longest-working lunar rover on the moon.

A lunar day equals 14 days on Earth, and a lunar night is the same length. The Chang'e-4 probe switched to dormant mode during the lunar night due to the lack of solar power.

The scientific tasks of the Chang'e-4 mission include conducting low-frequency radio astronomical observation, surveying the terrain and landforms, detecting the mineral composition and shallow lunar surface structure and measuring neutron radiation and neutral atoms.

The Chang'e-4 mission embodies China's hope to combine wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia.

China plans to launch the Chang'e-5 probe in 2020 to bring lunar samples back to Earth.

The Chang'e-5 probe includes a lander, an orbiter, an ascender and a returner. The key tasks of the mission will be lunar sample collection, takeoff from the moon, rendezvous and do.

China's lunar rover travels 367 meters on moon's far side

China's lunar rover Yutu-2 (Jade Rabbit-2) has driven 367.25 meters on the far side of the moon to conduct scientific exploration.

Both the lander and the rover of the Chang'e-4 probe ended their work for the 14th lunar day on Saturday (Beijing Time), and switched to dormant mode for the lunar night, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

During the 14th lunar day, Yutu-2 continued to move along the planned route. The scientific instruments on the lander and rover worked as planned.

The neutron radiation detector and low-frequency radio spectrometer on the lander worked normally and acquired first-hand scientific data. On the rover, the near-infrared spectrometer, panoramic camera, neutral atom detector and lunar radar carried out scientific exploration as planned.

China's Chang'e-4 probe, launched on Dec. 8, 2018, made the first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3, 2019.

The Chang'e-5 probe includes a lander, an orbiter, an ascender and a returner. The key tasks of the mission will be lunar sample collection, takeoff from the moon, rendezvous and docking in lunar orbit and high-speed reentry into Earth's atmosphere.

China's Chang'e-4 probe resumes work for 15th lunar day

The lander and rover of the Chang'e-4 probe have resumed work for the 15th lunar day on the far side of the moon after "sleeping" during the extremely cold night.

The lander woke up at 6:57 a.m. Tuesday (Beijing time), and the rover awoke at 5:55 p.m. Monday. Both are in normal working order, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

The rover, Yutu-2 or Jade Rabbit-2, has traveled 367.25 meters on the far side of the moon, with a plan to drive northwest and then southwest to continue its scientific exploration.

The Chang'e-4 probe, launched on Dec. 8, 2018, made the first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3, 2019.

China plans to launch its first Mars probe and the Chang'e-5 probe to bring lunar samples back to Earth later this year.
