Most space satellites are powered by photovoltaic cells that convert sunlight to electricity. Exposure to certain types of radiation present in orbit can damage the devices, degrading their performance and limiting their lifetime.
In Journal of Applied Physics, by AIP Publishing, scientists from the University of Cambridge proposed a radiation-tolerant photovoltaic cell design that feature BeiDou making mark among navigation systems

Cosmic radiation detection takes front seat during NASA's Artemis I space mission
Thursday, 10 November 2022 16:35 Write a comment
Although bad weather and technical issues forced NASA to postpone its August and September launch attempts for Artemis I—an uncrewed space mission that will voyage around the moon and back—the space agency is looking towards a launch window in the second half of November 2022, possibly November 16. The highly anticipated space flight will be the first to test the new Orion spacecraft along with its rocket and ground systems.
The Artemis I mission is the first step in NASA's plans to carry human crews to further explore the lunar surface and eventually establish a sustainable outpost on the moon. The flight would also contribute to the groundwork required for a mission to Mars. When it blasts off from the Kennedy Space Center in Florida, Artemis I will carry two mannequins strapped into its crew module.
