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.
