We asked NASA what it is actually like to be an Artemis II astronaut and their answer reveals a lot about the training to withstand the most terrifying moments in space

NASA took time out of its very busy current schedule to tell us what being an Artemis II astronaut in space actually involves.

With the first crewed mission to venture beyond low Earth orbit in decades, Artemis II already carries huge expectations, but the human side of the mission might be even more fascinating.

When we asked NASA what astronauts actually feel during the most intense moments of spaceflight, the agency gave a response packed with insight.

And while it avoids speaking for the individual astronauts themselves, the answer is full of telling details about just how these astronauts are prepared for the extremes.

What it is actually like to be an Artemis II astronaut

When we spoke to NASA about the Artemis II mission in space, the agency was quick to point out that it cannot define a single emotional experience for every individual astronaut.

“We don’t speak for how individual astronauts may feel during specific moments of a mission, as each crew member brings their own perspective and experience to flight.”

But from a technical standpoint, the agency made it very clear where things get most intense.

“From an operational standpoint, the most dynamic phases of any human spaceflight mission are typically launch and landing.”

It didn’t sugarcoat what those phases involve either.

“These are the periods where the spacecraft and crew experience the greatest physical forces and the most rapidly changing conditions.”

Even without describing emotions directly, that line alone gives a strong sense of just how extreme those moments really are.

The NASA guide to withstanding the most terrifying moments in space

What NASA focused on most was preparation, and just how deeply embedded it is in everything the crew does.

“Artemis II crew members are extensively trained and prepared for every phase of the mission.”

It also highlighted exactly what that training prioritizes.

“Their training is designed to ensure they can operate effectively in all scenarios, with a strong emphasis on procedures, teamwork, and situational awareness.”

And when it comes to how astronauts actually describe those intense moments, NASA offered a rare glimpse.

“While these phases are inherently complex, astronauts often describe their experience not in terms of anxiety, but as a combination of focus, anticipation, excitement, and awe.”

It added that this mindset is not accidental, but built through preparation and support.

“Grounded in the confidence that comes from rigorous preparation and the teams supporting them both on the ground and in space.”

So while launch and landing might sound like the most terrifying parts of the journey, NASA’s response suggests something surprising.

For Artemis II astronauts, those moments are less about fear and more about being ready, locked in, and fully prepared for whatever comes next.
