Astronaut Scott Kelly is back on Earth after 340 days in space, and being poked and prodded and tested every which way by NASA to learn the effect on the human body of all that time out there. He’s a great subject to study because he has an identical twin, Mark Kelly, who was on Earth all that time. This all matters because the body – and maybe mind – change plenty in space. And the US is committed to going to Mars in the 2030s. That’s a long trip. This hour On Point, space and the human body.

From Tom’s Reading List

Space.com: After Nearly a Year in Space, Astronaut Scott Kelly Would Love to Go Back — “Like all astronauts returning from space, Kelly is undergoing a recovery period. He described muscle aches and tiredness as his body re-adjusts to Earth gravity. Also, he said that his skin has not been used to touching anything for months, leading to the sensation of burning when he sits for long periods, for example.”

WIRED: Welcome Home, Scott Kelly. Now Let’s Go to Mars — “Successfully meeting the challenge of sending humans to Mars is also going to require continued progress in three other domains: advanced technologies for life support and habitation, power supply, radiation protection, in-space maintenance and repair, and propulsion; partnership between government and industry; and international cooperation.”

New Yorker: Moving To Mars — “For years, NASA has run experiments replicating the environments of space and alien planets. Rovers and robotics have been tested in the Arizona desert and in the Canadian Arctic. ‘Human factor’ studies in preparation for space-station duties have been carried out in a capsule at the Johnson Space Center and in an underwater lab off Key Largo. These days, the International Space Station provides an analogue for future long-duration missions.”

On Wednesday, May 26, 2016, U.S. military officials reported the first U.S. human case of bacteria resistant to an antibiotic used as a last resort drug. The 49-year-old woman has recovered from an infection of E. coli resistant to colistin. But officials fear that if the resistance spreads to other bacteria, the country may soon see germs impervious to all antibiotics. (Janice Carr/CDC via AP)

A new superbug resistant to every antibiotic has shown up in the U.S. We look at the threat, and our dwindling antibiotic options.
