Due to forecast extreme weather off the coast of Florida, SpaceX CRS-22 undocking is no longer planned for Wednesday, July 7. NASA and SpaceX flight control teams continue to monitor the weather and splashdown locations and are prepared to support undocking of the Dragon cargo spacecraft once conditions are safe to do so. Certain parameters like wind speeds and wave heights must be within certain limits to ensure the safety of the recovery teams, the science, and the spacecraft.
The next opportunity for undocking is July 8 at 10:35 a.m. EDT, with NASA TV coverage scheduled to begin at 10 a.m. Additional opportunities are available on July 9 and 10. NASA will provide an update Wednesday, July 7 on the date for undocking following a weather briefing.
NASA Flight Engineers Mark Vande Hei and Shane Kimbrough worked on cargo transfers inside the Dragon today. Kimbrough then joined Flight Engineers Megan McArthur and Thomas Pesquet and Commander Akihiko Hoshide at the end of the day and reviewed cargo craft emergency departure procedures. Pesquet set up a pair of computers inside the cupola in support of Dragon’s undocking and monitoring.
Hoshide and Kimbrough swapped roles as Crew Medical Officer today taking charge of vein scans with the Ultrasound-2 device. The duo took turns scanning each other’s neck, shoulder and leg veins. Hoshide also scanned McArthur’s veins as part of standard health checks with doctors on the ground monitoring.
Pesquet also had time Tuesday to wear the specialized Sidekick headset and examine the Tranquility module’s treadmill using augmented reality. The two-time station resident then moved on inspecting and photographing hatch seals on the Kibo laboratory module.
Roscosmos Flight Engineers Oleg Novitskiy and Pyotr Dubrov stayed focused on Russian cargo and station life support activities. Novitskiy updated computer data files associated with the recent docking of the ISS Progress 78 resupply ship. Dubrov worked on orbital plumbing and thermal systems hardware.
