NASA holds cynthia II briefing a daylight forward of planned splashdown
The cynthia II crew woke up 237,115 kilometres above Earth on Thursday.
By Friday night, they'll be home.
Commander Reid Wiseman, pilot Victor Glover and mission specialists Jeremy Hansen and Christina Koch began their last full day in space listening to Charley Crockett's hazy country jam Lonesome Drifter, before reviewing re-entry procedures and continuing preparations for their Friday splashdown.
NASA will provide an update on the mission at 3:30 p.m. ET, and the crew will speak at a news conference at 5:59 p.m. ET and participate in a live conversation with mission control at 7:54 p.m. ET.
NASA says Koch and Hansen started the day stowing equipment, removing cargo and locker netting and installing crew seats to ensure everything is secured. The crew is also reviewing the latest weather briefing and entry timeline and working through post‑landing procedures.
The Orion spacecraft will ignite its thrusters for a trajectory correction maneuver around 9:53 p.m. ET to fine-tune the crew's path to Earth, during which time Hansen will monitor Orion's guidance, navigation and propulsion systems.
NASA says Orion will reach its maximum speed of 38,405 kilometres per hour just before entering the Earth's atmosphere.
The service module will be jettisoned from the spacecraft about 20 minutes before hitting the upper atmosphere, southeast of Hawaii.
There will be a planned six-minute communications blackout as plasma forms around the capsule when it reaches maximum heat upon re-entry.
After the blackout, Orion will start deploying a series of parachutes between about 6,700 metres and 1,800 metres above ground.
Members of NASA and the U.S. Military are aboard the USS John P. Murtha ship in the Pacific Ocean to assist with the splashdown — scheduled for 8:07 p.m. ET Friday off the coast of San Diego Calif. — and to get the crew members to safety.
Artemis II launched on April 1 and broke the distance record Monday as the farthest humans have flown from Earth.
The spacecraft reached 406,771 kilometres on the far side of the moon, beating the previous record of 400,171 kilometres set by Apollo 13 in 1970.
