41st flight of 2025: Hawaiian HA 459 from HNL/PHNL Honolulu Daniel K. Inouye to ICN/RKSI Seoul Incheon. Airbus A330-200 registered N385HA. This is the 1005th flight of all time. It is my 39th departure from the U.S. 50 states and D.C., the 41st departure from the U.S. and its territories, and also the 41st arrival to the Republic of Korea. 🇺🇸✈️🇰🇷

The ride to orbit was much smoother than I had anticipated. Apart from the final minute before SECO, I barely felt any G-forces—it honestly felt like just another flight. I had imagined it would feel like being in an elevator that suddenly drops, but that sensation never came. If I hadn’t set free Tyler, the polar bear zero-gravity indicator, I might not have realized we were already weightless. I think being tightly strapped into our seat buckets made the transition less noticeable. The first few hours in microgravity weren’t exactly comfortable. Space motion sickness hit all of us—we felt nauseous and ended up vomiting a couple of times. It felt different from motion sickness in a car or at sea. You could still read on your iPad without making it worse. But even a small sip of water could upset your stomach and trigger vomiting. Rabea spent some time on the ham radio, making contact with Berlin. No one asked opening the cupola on the first day—we were all focused on managing the motion sickness. We had a movie night watching our own launch and went to sleep a bit earlier than scheduled. We all slept really well. By the second morning, I felt completely refreshed. The trace of motion sickness is all gone. We had breakfast, took a few X-ray images, and opened the cupola three minutes after midnight UTC—right above the South Pole. Stay tuned.

36th flight of 2025: SpaceX Fram2 from LC-39A, Kennedy Space Center, via the South Pole and the North Pole, to Pacific Ocean near Los Angeles or Oceanside. Crew Dragon C207 “Resilience”. This is my 1000th flight of all time.

L-2 days Today was a busy day. I woke up at 2 PM and departed from our quarantine facility at 3:30 PM in a convoy of three Teslas. With NASA security police escort leading the way, we didn’t have to stop for traffic lights. We had breakfast at HangarX before heading to the pad. Arriving at the suit-up room near Pad 39A, we received our satchels containing some necessary medicines, along with a flight iPhone, iPad, Apple Watch, and AirPods Pro. SpaceX had 3D-printed a tether to connect the two earbuds so they wouldn’t get lost in microgravity. I spent some time loading apps, including X, YouTube, and an offline version of OpenStreetMap, to which I had made many contributions in its early years. I also downloaded apps that use iPhone and iPad sensors to monitor cabin pressure—as an independent redundancy in the unlikely event of cabin depressurization. After that, we had a quick weather briefing, suited up, and jumped into the Teslas for the ride to the pad. Unlike all previous Dragon missions, we’ll launch from the East Coast and splashdown the West Coast. This means we’re actually traveling from one place to another. We’d pack our clothes, personal phones and watches into a bag, which SpaceX staff will transport to Hawthorne, and upon our splashdown, hand over to us on the recovery ship. Ingress, buckling in, seat rotation, comms check, and suit leak check — everything went smoothly. By the time the dry dress rehearsal completed, it was already dark and raining. The walkway from the crew access arm to the tower isn’t fully protected from rain. When the side hatch reopened, the SpaceX ninja team met us with umbrellas and rain jackets, which we wore over our spacesuits to keep our “dry dress” from turning into a “wet dress.” We returned to the suit-up room for a short debrief, had “lunch,” and then headed back to the quarantine facility at 11 PM. The rest of the night was filled with a few more meetings to review some final details. The flight software on Dragon had been frozen, and there were some newly discovered bugs we needed to be aware of. I also had a call with our psychotherapist, Rebecca, who has been working with us since the very beginning of training. At 2:30 AM, Ben, Space Operations Physician at SpaceX, and I went out for a 2-mile run. Jaime, Ben and I have been running every night during quarantine, and sometimes I feel like they have become my bodyguards in Merritt Island’s darkness. Tomorrow, there’s a scheduled Starlink launch at nearby SLC-40. I’m hoping it goes well and that I might watch it from a distance at our quarantine facility.

Join me at 17:30 EDT / 21:30 UTC, along with @TurkeyBeaver @astro_jannicke @rprogge @Icetrek. We’ll talk about our upcoming space mission, fram2—the first human spaceflight to Earth’s polar regions. https://t.co/VthH4uq1e1

L-4 days One of the key things we must do during the quarantine is shift sleep schedule to match the launch time. On launch day, we’ll be waking up at 14:30 EDT. If we take the first opportunity at 21:46:50 EDT on March 31, we’ll go to sleep at 08:36 EDT / 12:36 UTC on April 1. For the second opportunity at 23:20:00 EDT, we’ll go to sleep at 09:08 EDT / 13:08 UTC. If we end up launching with the third or fourth opportunity, we’ll shift our sleep in the opposite direction post launch, going to sleep at 06:47 EDT / 10:47 UTC. Our nominal mission lasts 86 hours and 38 minutes—or about three and a half days—so we’ll need to shift our sleep schedule by half a day over the course of the mission. During that time, we’ll pass over the North Pole 55 times and the South Pole 56 times. Today, I woke up around noon and had breakfast at 2 PM. In the afternoon, we headed to HangarX for an interview with CBS News. After that, we moved to the suit-up room and walked through the dry dress process, which is scheduled for March 29. We also got a close-up look at our rocket—Dragon is already stacked with Falcon 9 in the hangar. A full lap around LC-39A is 2.8 km. We wrapped up the day with a pad run—it took me a little over 16 minutes for that, averaging 11.1 km/h.
