From abrupt changes in gravity to galactic cosmic radiation, astronauts face numerous challenges as they push to explore further into the unknown. Dr. Emmanuel Urquieta, from the Center for Space Medicine at the Baylor College of Medicine, joins Viewpoints this week to help us understand some of the health impacts of spending time in space and the hurdles that come with longer missions like sending humans to Mars.
The Jupiter moon, Europa is 390 million miles away from Earth. In 2025, the NASA Europa Clipper mission launches and is estimated to arrive in Jupiter’s orbit by 2031. Why Europa? Underneath its radiated surface, the icy moon is believed to host a vast ocean similar to Earth’s that has ample conditions for complex life. Author David W. Brown joins Viewpoints this week to shed some light on the Jovian moon and some of the challenges that came with the lengthy approval of this deep space mission.
We know about the planets within the Milky Way Galaxy, but what about planets outside of our neighborhood? We talk to Dr. Donald Goldsmith about “exoplanets” and where science stands on the issue of life thriving somewhere else in the universe.
