The lander and rover of the Chang'e-4 probe have resumed work for the ninth lunar day on the far side of the moon after "sleeping" during the extremely cold night. The lander woke up at 8:10 a.m. Sunday, and the rover, Yutu-2 (Jade Rabbit-2), awoke at 8:42 a.m. Saturday, according to the Lunar Exploration and Space Program Center of the China National Space Administration. For the ninth lunar day, the lander's neutron radiation detector and low-frequency radio detector, as well as the rover's infrared imaging spectrometer and other instruments will be restarted to conduct scientific tasks including moon surface observation and composition analysis. 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. A lunar day equals 14 days on Earth, and a lunar night is the same length. The Chang'e-4 probe switches to a dormant mode during the lunar night due to the lack of solar power. As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation cycle, and the same side always faces Earth. The scientific tasks of the Chang'e-4 mission include 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 human wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia. Source: Xinhua News
Seeking innovative ideas for exploring lunar caves Paris (ESA) Aug 22, 2019 How would you design a system to detect, map and explore caves on the Moon? Our latest hunt for ideas is seeking novel initiatives that address this question. While the surface of the Moon has been well-documented with cameras on board several satellite missions, relatively little is known about the presence and nature of subsurface cavities. In volcanic areas of the lunar maria, planetary geologists have identified pits that could be related to the collapse of cavities such as lava tubes - where ... read more
