At 9:46 AM Beijing time on April 1, the Dragon spacecraft carrying 4 crew members launched from the Kennedy Space Center. A little over ten minutes later, the spacecraft separated from the rocket, and the spacecraft entered orbit. This is humanity's first mission to fly in a polar orbit.

For the Chinese people, what is even more noteworthy is that the financer of this mission is named Wang Chun, a Chinese who changed his nationality in recent years. He spent 200 million dollars to purchase 4 tickets for this mission. Wang Chun was born in Tianjin, was a coder in Wudaokou in 2012, became one of the first Bitcoin miners in China in 2013, and co-founded F2pool, which later grew to be the largest mining pool in the world.

Below is the "diary" sent back from space by Wang Chun from the moment before launch to the first day after entering orbit.

Day 1

7:41 AM · Apr 1, 2025

Wang Chun: 2 hours and 5 minutes to launch, side hatch closed. We are ready for takeoff🚀

8:51 AM · Apr 1, 2025

Countdown to launch, 55 minutes remaining.

Wang Chun: The 36th flight of 2025: SpaceX's Fram2 launched from pad 39A at Kennedy Space Center, passing over the South Pole and North Pole, heading towards the Pacific near Los Angeles or Oceanside. The crewed Dragon spacecraft C207 "Resilience". This is my 1000th flight in my life.

9:46 AM · Apr 1, 2025

Falcon 9 ignites and takes off.

10:00 AM · Apr 1, 2025

The spacecraft separates, and the Dragon spacecraft enters orbit.

Wang Chun: Today, we become the 681st humans to cross the Kármán line, and the 626th humans to orbit the Earth.

SpaceX announced on the first day after the launch:

On the first day in orbit, Fram2 crew began their research activities, including a study on how human cognition adapts to the spaceflight environment in the first few hours after arriving in space.

Amateur radio enthusiasts from Berlin and across Europe communicated with crew member Rabea Rogge, which is part of the Fram2 program.

The crew also completed the first in-orbit Starlink test!

Day 2

12:17 AM · Apr 2, 2025

Wang Chun: The process of entering orbit was much smoother than I expected. Except for the last minute before second engine cutoff (SECO), I hardly felt any acceleration forces—it really felt like an ordinary flight.

I expected to feel like suddenly falling in an elevator, but that feeling never occurred. If I hadn't unhooked Taylor—the polar bear zero-gravity indicator, I might not have realized we were already in a weightless state. I think we were strapped tightly in our seats, which made the transition less noticeable.

The first few hours in a microgravity environment were not very comfortable. We all suffered from space motion sickness—feeling nauseous and vomiting several times. This is different from the feeling of car sickness or seasickness. You can still read on the iPad without worsening symptoms. But even sipping a little water can make your stomach uncomfortable and trigger vomiting.

On the first day, no one suggested opening the cupola window—we all focused on dealing with space motion sickness. We watched our launch video and went to bed a bit earlier than planned. We all slept well.

On the Dragon spacecraft flying in a polar orbit, crew member Rabea spent some time on amateur radio contacting enthusiasts in Berlin.

By the next morning, I felt refreshed. The traces of space motion sickness had completely disappeared. And three minutes after midnight Coordinated Universal Time, I opened the cupola window—at that moment, we were just above the South Pole 👇

We had breakfast and took a few X-ray photos (one of the experiments in this mission's science trials).

Wang Chun also sent back a video of the Earth's poles taken through the Dragon spacecraft window, as well as images of the crew activities inside the Dragon spacecraft 👇
