With NASA astronaut Shane Kimbrough  monitoring aboard the International Space Station, a SpaceX cargo Dragon spacecraft undocked from the International Docking Adapter on the station’s space-facing port of the Harmony module at 10:45 a.m. EDT.

Dragon will fire its thrusters to move a safe distance from the space station during the next 36 hours. On Friday, July 9, Dragon will conduct a deorbit burn to begin its re-entry sequence into Earth’s atmosphere. Dragon is expected to splash down at approximately 11:29 p.m. in the Gulf of Mexico near Tallahassee, Florida. The splashdown will not be broadcast.

Splashing down off the coast of Florida enables quick transportation of the science aboard the capsule to the agency’s Kennedy Space Center’s Space Station Processing Facility, delivering some science back into the hands of the researchers as soon as four to nine hours after splashdown. This shorter transportation timeframe allows researchers to collect data with minimal loss of microgravity effects. The Dragon’s departure will be the second splashdown of a U.S. commercial cargo craft off the Florida coast. Previous cargo Dragon spacecraft returned to the Pacific Ocean, with quick-return science cargo processed at SpaceX’s facility in McGregor, Texas, and delivered to NASA’s Johnson Space Center in Houston.

Dragon launched June 3 on a SpaceX Falcon 9 rocket from Launch Complex 39A at Kennedy, arriving at the station a little less than 16 hours later. The spacecraft delivered more than 7,300 pounds of research investigations, crew supplies, and vehicle hardware to the orbiting outpost. Dragon’s external cargo “trunk” carried six new ISS Roll-Out Solar Arrays (iROSAs), two of which Expedition 65 crew members Kimbrough and Thomas Pesquet, an ESA (European Space Agency) astronaut, installed during three spacewalks June 16, 20, and 25.

Some of the scientific investigations Dragon will return to Earth include:

  • Lyophilization-2 examines how gravity affects freeze-dried materials and could result in improved freeze-drying processes for pharmaceutical and other industries. Freeze-drying also has potential use for long-term storage of medications and other resources on future exploration missions.
  • Molecular Muscle Experiment-2 tests a series of drugs to see whether they can improve health in space, possibly leading to new therapeutic targets for examination on Earth.
  • Oral Biofilms in Space studies how gravity affects the structure, composition, and activity of oral bacteria in the presence of common oral care agents. Findings could support development of novel treatments to fight oral diseases such as cavities, gingivitis, and periodontitis.

SpaceX CRS-22 undocking is planned for Thursday, July 8 at 10:35 a.m. EDT, with NASA TV coverage scheduled to begin at 10 a.m. NASA and SpaceX flight control teams continue to monitor the weather and splashdown locations. 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. Additional opportunities are available on July 9 and 10. The space freighter’s departure had been scheduled for earlier this week but was postponed due to weather conditions off the coast of Florida.

Meanwhile, the Expedition 65 crew members stayed focused on a variety of science activities including human health, robotics and physics.

Flight Engineers Shane Kimbrough and Thomas Pesquet took turns working out on an exercise cycle Wednesday for a fitness test. The veteran astronauts attached sensors to their chests and pedaled for an hour on the device more formally known as the Cycle Ergometer with Vibration Isolation and Stabilization, or CEVIS. The test took place in the U.S. Destiny laboratory module and measures how microgravity affects the duo’s physical exertion, or aerobic capacity.

NASA Flight Engineer Megan McArthur focused on electronics maintenance and robotics research throughout Wednesday. The two-time space visitor powered up a cube-shaped AstroBee robotic helper and tested new technology that monitors the acoustic environment of the station. SoundSee seeks to demonstrate that “listening” to station components can help detect anomalies in spacecraft systems that need servicing.

Space manufacturing using colloids is being investigated for the ability to harness nanoparticles to fabricate new and advanced materials. Station commander Akihiko Hoshide conducted three runs inside the Microgravity Science Glovebox of the InSPACE-4 study today that could improve the strength and safety of Earth and space systems.

The trio that launched to the station aboard the Soyuz MS-18 crew ship practiced an emergency evacuation drill during the morning. NASA Flight Engineer Mark Vande Hei joined cosmonauts Oleg Novitskiy and Pyotr Dubrov and reviewed procedures such as donning gas masks, quickly entering the Soyuz spacecraft, undocking and reentering the Earth’s atmosphere.

Vande Hei later assisted McArthur with cable management work inside the Tranquility module. Novitskiy and Dubrov wrapped up the day disconnecting antenna cables inside their Soyuz vehicle.

NASA and SpaceX are targeting no earlier than Wednesday, July 21, for Crew Dragon Endeavour’s International Space Station port relocation operation. Kimbrough, McArthur, Hoshide Pesquet will suit up in their launch and entry spacesuits for Crew Dragon’s automated relocation maneuver from the forward to the space-facing port of the station’s Harmony module. The maneuver frees up the forward port to prepare for the arrival of NASA’s Boeing Orbital Flight Test-2 (OFT-2) mission at the microgravity laboratory at the end of July.

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.
