Orion will hurtle through Earth’s atmosphere at more than 30 times the speed of sound, in that NASA it expects to be the most demanding segment Artemis II month work.
On landing day, Artemis II mission director Rick Henfling and his mission control team will run the final leg home A 10-day spaceflight. After liftoff, the controllers will inform the four astronauts – Commander Reid Wisemanpilot Victor Glover, Christina Koch, and Jeremy Hansen – in the weather in the splashdown area, then remove them to secure loose gear and climb into their pressure suits.
The last small steering wheel is burnt space will aim the Orion spacecraft in the target area of the Pacific Ocean, west of San Diego, California, where the Navy ship will be waiting Friday evening. On the ground, engineers will also use flight support software so the capsule can still steer itself in space if its main computers fail.
This home structure carries the following additional differences Artemis Iwhen pieces of Orion’s heat shield suddenly broke off during the descent of an unmanned test flight. Engineers later said the problem was caused by hot gas growing faster than it could have escaped during the mission. “skip” the entry. But instead of redesigning the shield, NASA chose to change the capsule’s trajectory in space to avoid extreme temperatures.

Long before the launch, the heat shield was like that Wiseman’s top concern by Jim Free, who led NASA’s Artemis rocket and spacecraft programs in 2023.
“Every time you see me come in, you back off,” Wiseman told Free in a press conference, “because I’m coming in for heat protection.”

Instead of repeating the same deep jumps as the first flight, Artemis II will use a softer “higher” approach, Henfling said. Orion will still dip in and out of space before the final dip, but with a dramatic rise and fall. That change shortens the splash distance and keeps the gas pressure spikes seen in the first flight to a tolerable range. NASA brought in an independent review team before approving the revised plan.
Glover said he had been thinking about re-entering since April 3, 2023: the date he was assigned to the Artemis II crew.

“At one of the first press conferences, we were asked what we were looking forward to, and we said, ‘Splashdown,'” he said during the meeting. a lot a long call with reporters from the capsule on Wednesday night. “The fireball ride in space is intense.”

As shocking as it is, NASA officials said that in 2024 damage to Artemis I’s heat shield would not harm the crew.
“They wouldn’t have felt any disturbance inside the vehicle, there wouldn’t have been any overheating in the structure, and the guidance would have put them where the Navy needed to return them,” said Amit Kshatriya, NASA’s chief executive officer.
As Orion approaches Earth, communications will switch from the large antennas to track the moon The Deep Space Network to near-Earth relay satellites. About 20 minutes before entry, the service module – the section with the solar arrays and main engine – will break apart and burn up over the ocean, leaving only the crew capsule to deal with the punishing heat.

The entry begins about 75 miles up, Orion is traveling at 25,000 mph. The air that accumulates in front of the cap will heat up to about 5,000 degrees Fahrenheit, turning it into a plasma that can briefly cut contact with the radio. Inside, the crew will feel about 3.9Gs – a crushing pressure four times their weight.
While astronauts often describe potential records as distractions, Wiseman admitted there is one he memorized during training — one that might beat the previous re-entry speed by perhaps 200 miles per hour or more. Apollo 10’s speed translated to about Mach 37, according to it 1969 press kit.
“We still get a little giggles when we see the click at Mach 39 on entry,” he said months ago. launching on April 1.
Once Orion slows down enough, a solid parachute sequence will take over. The cover over the nose will inflate, two small drogues will pop out to stabilize the capsule, and three large orange parachutes will open in stages to reduce speed for survival. Small thrusters will tip the capsule to hit the waves at a safe angle near the California coast.
After landing, NASA will keep Orion powered up for about two hours to test how temperatures inside the capsule change as it cools in the Pacific, even after the astronauts are on the recovery ship.
Dan Flores, who is on the recovery team, may be biased but he calls it his favorite part of the job.
“We have friends who fly to the moon,” he said. “This is where we get to bring our friends back home to their families.”
