Space travel isn't a movie. It’s loud, it’s sweaty, and honestly, it’s a lot of waiting around for things that might break. When the SpaceX Crew 10 launch finally lit up the Florida sky on March 14, 2025, it wasn't just another routine taxi ride to the stars. It was a massive milestone for the Commercial Crew Program, marking a full decade of these "operational" missions. But if you think it went off without a hitch or that it was just a "copy-paste" of the nine missions before it, you've got some catching up to do.
The Scrub That Almost Ruined Everything
Let's talk about that first attempt on March 12. Most people see a "scrub" on the news and think, "Oh, the weather was bad." Not this time. The weather was actually perfect—95% "go" according to the 45th Weather Squadron.
The real culprit? A tiny pocket of air.
Seriously. About 44 minutes before liftoff, SpaceX engineers noticed a weird pressure reading in the hydraulics of the "strongback"—the massive metal arm that holds the Falcon 9 steady while it’s being fueled. They suspected air was trapped in the lines of one of the clamps. You can’t launch a multi-million dollar rocket if the clamp might not let go properly. So, they called it. Everyone went home.
It took two days of flushing those hydraulic lines to get it right. By the time Friday evening rolled around, the tension at Kennedy Space Center's Launch Complex 39A was thick enough to cut with a knife. But at 7:03 p.m. ET, the nine Merlin engines on the first stage (booster B1090) ignited.
The roar was immense.
Meet the Crew: Not Just "The Astronauts"
We usually just see four people in white suits, but this group was a fascinating mix of seasoned veterans and total rookies.
- Anne McClain (NASA): The Commander. This was her second trip. She’s a West Point grad and a former Army helicopter pilot with over 200 days in space under her belt already. She’s basically the steady hand you want if things get weird.
- Nichole Ayers (NASA): The Pilot. This was her big debut. She was actually the first member of the 2021 NASA astronaut class to be assigned to a mission. That’s a huge deal in the astronaut office.
- Takuya Onishi (JAXA): A Mission Specialist from Japan. He’s a former commercial airline pilot. Imagine going from flying a Boeing 767 to a SpaceX Dragon.
- Kirill Peskov (Roscosmos): The Russian Mission Specialist. Like Ayers, this was his first flight.
The chemistry mattered because they weren't just going up for a weekend. They were scheduled for a grueling 148-day stay.
The "Endurance" Swap Mystery
Here is something the casual observer totally missed: the ship they used wasn't the one they planned for. Originally, NASA wanted to debut a brand-new Dragon capsule named Grace (C213). It was supposed to be the "final" Crew Dragon ever built.
But Grace wasn't ready.
NASA didn't want to wait until late April, so they called an audible. They pulled Endurance out of the hangar. If that name sounds familiar, it’s because Endurance is a workhorse—it had already flown Crew-3, Crew-5, and Crew-7. This SpaceX Crew 10 launch was its fourth trip to orbit. SpaceX is basically proving that these capsules are more like airplanes than one-off rockets.
Life on the ISS Wasn't Exactly a Vacation
Once they docked on March 16, 2025, the work started immediately. They didn't just float around looking at the Earth. They were part of Expedition 72 and 73, which meant a lot of "science-ing."
They spent months working on things like:
- Bio-fabrication: Basically trying to "print" human organ tissues in microgravity because cells grow differently when they aren't being squashed by gravity.
- DNA Sequencing: Testing how space radiation affects the human genome in real-time.
- Fire Safety: Studying how "cool flames" burn, which is vital for making sure the ISS doesn't turn into a fireball.
But it wasn't all smooth sailing. During their stay, the station had to deal with some "commodity" concerns. A cargo resupply ship (the Cygnus) had its shipping container damaged on the ground, which delayed some food and supplies. The crew had to tighten their belts for a bit.
The Splashdown: A New Kind of Landing
Fast forward to August 9, 2025. After 145 days of being docked to the Harmony module, the crew finally came home.
But they didn't land in the Atlantic like most SpaceX missions.
They splashed down in the Pacific Ocean off the coast of San Diego, California. It was actually one of the first times a Commercial Crew mission used the Pacific for a primary landing site. The recovery ship, MV Shannon, hauled them out of the water at 8:33 a.m. PT.
Why Should You Care?
You might think, "Okay, they went up, they came down. Big deal."

It is a big deal. The SpaceX Crew 10 launch was the bridge to the next era. While these four were orbiting, NASA was busy finalizing the "Artemis" moon missions. The data McClain and her team gathered about how their bodies reacted to five months in space is directly being used to plan the first human missions to Mars.
Honestly, the fact that we now view a rocket launch as "routine" is the biggest success of all. It means the tech is working.
What’s Next for Space Fans?
If you're looking to follow the next steps in human spaceflight, you should:
- Track the Booster: Follow the flight history of B1090. It’s a flight-proven booster that’s likely going to launch several more times this year.
- Watch for Crew-11 Updates: That mission had its own drama recently (a medical evacuation), showing that even after ten successful missions, space remains "hard" and unpredictable.
- Check the NASA Live Feed: They often stream the "science" segments where you can see the astronauts actually working on the experiments mentioned above.
The era of SpaceX Crew 10 is over, but the data they brought back is just starting to be unpacked. It's a wild time to be looking up.
