NASA’s new administrator, Jared Isaacman, also had questions when he took the job in December 2025. But in January, after a review, Isaacman announced he had “full confidence” in Orion’s heat shield using the new entry profile. He invited Ars Technica to Washington, DC, to sit in on a technical briefing at the time. From this detailed information, it sure seemed like NASA had put in the hard work and testing to back up its decision.

Even so, you’ve got to go fly to be sure. And that’s what will happen this evening.

“There’s no question that I’ll be anxious,” said Amit Kshatriya, the space agency’s top civil servant, this week. “We’ve done the work. It’s impossible to say you don’t have irrational fears left. But I don’t have any rational fears.”

Splashdown

After the heat shield bears the brunt of the heating, Orion will jettison the “forward bay cover” at the top of the spacecraft at about 35,000 feet. This protective cover must be cast off for three small, drogue parachutes to deploy at about 22,000 feet. After three pilot parachutes deploy, the mains are due to come out at about 6,000 feet. The aim is to slow the spacecraft to 20 mph at splashdown.

Parachutes have been deploying from returning spacecraft for nearly seven decades. Even so, it’s a nervous moment since there is no backup. If they fail, the mission fails.

Under a nominal reentry, the crew will experience two brief periods of 3.9 Gs. However, in some scenarios, these G-loads could reach 7.5 Gs, entry flight director Rick Henfling said.

After splashdown, recovery crews from the USS John P. Murtha will approach Orion and deploy an inflatable device at Orion’s hatch, known as the “front porch.” Winds and seas at the recovery area are forecast to be calm. Recovery crew members, in a nominal scenario, will extract astronaut Christina Koch first, followed by Victor Glover, Jeremy Hansen, and finally Wiseman.

They will then be transported by two helicopters back to the recovery ship for an initial checkout. If all goes well, the triumphant astronauts will fly back to Houston on Saturday morning to be reunited with their family members.
