Artemis II: 11. Science surprises

The Artemis II mission nears its end as the crew prepares for re-entry, currently traveling at 2,600 miles per hour but expected to reach 25,000 mph upon return. The crew appreciates the flywheel exercise machine, crucial for maintaining cardiovascular and muscle strength in microgravity. Space journalist Kristin Fisher joins hosts Tim Peake and Maggie Aderin to discuss the mission. NASA's lead science officer for Artemis, Dr. Kelsey Young, highlights the success of the mission's science objectives, including capturing impact flashes on the moon's surface and the value of human observation over robotic assets. The crew's training, including a sandbox exercise to understand lunar surface observation, has enabled them to contribute meaningfully to lunar science. A postcard from BBC science editor Rebecca Murrell describes the cramped conditions inside the Orion capsule and the challenges of re-entry.
