The SpaceX Dragon resupply ship’s stay at the International Space Station has been extended until Saturday after unfavorable conditions were reported at the splashdown zone in the Pacific Ocean. In the meantime, time-sensitive payloads are still being readied for return to Earth as the crew wraps up final cargo packing.

Robotics controllers will operate the Canadarm2 to detach Dragon from the International Space Station’s Harmony module on Friday. It will be remotely released into Earth orbit Saturday at 9:24 a.m. EDT before finally splashing down in the Pacific Ocean around 3 p.m. Flight Engineer Scott Tingle will be in the Cupola monitoring Dragon as it slowly backs away from the space station.

NASA TV’s live coverage of Dragon’s departure begins Saturday at 9 a.m. The space freighter’s parachuted splashdown 403 miles off the coast of Long Beach, Calif. will not be televised.

Two NASA astronauts are looking ahead to their next spacewalk scheduled for May 16. Veteran spacewalkers Ricky Arnold and Drew Feustel took their body measurements today to ensure a proper fit inside their U.S. spacesuits. The duo will work outside the orbital lab for about 6.5 hours to swap out thermal control gear that circulates ammonia to keep station systems cool.

Japanese astronaut Norishige Kanai, who will assist the spacewalkers in two weeks, began configuring the Quest airlock where the 210th spacewalk at the station will be staged. He also trained to detect and clean ammonia from the spacesuits should they become contaminated during the maintenance spacewalk.
