Nerves Mount as NASA’s Artemis II Prepares for Re-Entry and Splashdown

The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data, and took in unprecedented Moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday’s splashdown.

Reid Wiseman, Victor Glover, Christina Koch , and Jeremy Hansen are scheduled to splash down in the Pacific Ocean off the coast of San Diego at 5:07 pm local time (2 am Saturday, SA time) .

The Stakes

Until the astronauts are home safe, it’s too early to talk about success, NASA’s Associate Administrator Amit Kshatriya told a briefing Thursday.

“When we can start celebrating is when we have a crew safely in the medbay of the ship. That’s really when we can allow the emotions to take over.”

The stakes are particularly high given concerns that arose during Artemis I (2022), where the Orion heat shield eroded in unexpected ways.

The Heat Shield

During re-entry, the Orion spacecraft will face temperatures peaking around 2,760 degrees Celsius half as hot as the surface of the Sun.

The astronauts will come hurtling back at a maximum velocity of 34,965 feet per second more than 30 times the speed of sound.

The heat shield is meant to slowly erode (“ablate”) to protect the capsule, a process that during Artemis I was disrupted.

To minimise risk, NASA has changed the re-entry path they used in that test mission.

“We have high confidence in the system and the heat shield and the parachutes and the recovery systems we put together,” Kshatriya said.

“The engineering supports it, the Artemis I flight data supports it. All of our ground tests support it. Our analysis supports it. And tomorrow, the crew is going to put their lives behind that confidence.”

Emotional Week

Catherine Hansen , the wife of astronaut Jeremy, told AFP that “it has been a very emotional week.”

“There’s been a lot of happiness and excitement, a lot of joy, but also some anxiety and some wanting to get him home safely.”

The Mission’s Legacy

The second phase of the Artemis program is a “test mission” to verify the reliability of the Orion capsule.

The voyage was marked by historic achievements:

• Victor Glover: First person of colour to fly around the Moon

• Christina Koch: First woman to fly around the Moon

• Jeremy Hansen: First non-American to fly around the Moon

The Bottom Line

“We can’t forget that this is a test flight,” NASA official Lakiesha Hawkins said.

Mission commander Reid Wiseman reflected: “What we really hoped in our soul is that we could, for just a moment, have the world pauseand remember that this is a beautiful planet in a very special place in our universe.”

Now, the world waits. The capsule is coming home. And NASA is holding its breath.
