- The Chang'e-4 lunar lander with a German instrument for measuring space radiation on board, the Lunar Lander Neutron, and Dosimetry (LND) instrument has measured temporally resolved cosmic radiation for the first time.
- Space radiation on the moon is two to three times higher than that on the International Space Station (ISS). This could be one of the biggest dangers for future moon explorers.
- The discovery provides the first full measurements of radiation exposure from the lunar surface, vital information for NASA, and others aiming to send astronauts to the moon.
