James Welsh, a radiation oncologist and author, discusses the biological impacts of space radiation on astronauts, revealing surprising resilience in human bodies compared to sensitive spacecraft electronics. He stresses that electronic failure may limit space missions more than health issues. Physicists Biju Patla and Neil Ashby present their innovative approach to establishing a lunar time system using atomic clocks, aiming to facilitate navigation and coordination on the Moon, with aspirations for a similar system on Mars.
