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.
