NASA astronauts Stephen Bowen and Woody Hoburg, along with UAE (United Arab Emirates) astronaut Sultan Alneyadi, and Roscosmos cosmonaut Andrey Fedyaev arrived at the International Space Station on Friday, as the SpaceX Dragon, named Endeavour, docked to the complex at 1:40 a.m. EST while the station was 260 statute miles over the Indian Ocean off the east coast of Somalia.

Docking was delayed slightly as mission teams completed troubleshooting of a faulty docking hook sensor on Dragon. The NASA and SpaceX teams verified that all of the docking hooks were in the proper configuration, and SpaceX developed a software override for the faulty sensor that allowed the docking process to successfully continue.

Following Dragon’s link up to the Harmony module, the astronauts aboard the Dragon and the space station will begin conducting standard leak checks and pressurization between the spacecraft in preparation for hatch opening scheduled for 3:18 a.m.

Crew-6 will join the Expedition 68 crew of NASA astronauts Frank Rubio, Nicole Mann, and Josh Cassada, as well as Koichi Wakata of JAXA (Japan Aerospace Exploration Agency), and Roscosmos cosmonauts Sergey Prokopyev, Dmitri Petelin, and Anna Kikina. For a short time, the number of crew on the space station will increase to 11 people until Crew-5 departs.

NASA Television and the agency’s website are continuing to provide live continuous coverage of the agency’s SpaceX Crew-6 mission.

Station Crew Awaits Ax-1 Departure and Crew-4 Launch

International Space Station Configuration. Six spaceships are parked at the space station including the SpaceX Dragons Endurance and Endeavour; the Northrop Grumman Cygnus space freighter; and Russia's Soyuz MS-21 crew ship and the Progress 79 and 80 resupply ships.
International Space Station Configuration. Six spaceships are parked at the space station including the SpaceX Dragons Endurance and Endeavour; the Northrop Grumman Cygnus space freighter; and Russia’s Soyuz MS-21 crew ship and the Progress 79 and 80 resupply ships.

The integrated NASA, Axiom Space, and SpaceX teams have agreed on a plan for the Axiom Mission 1 (Ax-1) crew to undock from the International Space Station at 8:35 p.m. EDT Saturday, April 23, for a splashdown off the coast of Florida about 1:46 p.m. Sunday, April 24. The decision was made based on the best weather for splashdown of the first private astronaut mission to visit the International Space Station and the return trajectory required to bring the crew and the SpaceX Dragon Endeavour spacecraft back to Earth safely.

NASA will provide live coverage of departure activities beginning at 6:15 p.m. Saturday, April 23, with hatch closure targeted for 6:30 p.m. Coverage will resume at 8:15 p.m. for the undocking. Teams will continue to monitor weather at the splashdown sites prior to undocking to ensure conditions are acceptable for a safe recovery of the Ax-1 astronauts and Dragon spacecraft.

NASA and Axiom mission planning prepared for the possibility of additional time on station for the private astronauts, and there are sufficient provisions for all 11 crew members aboard the space station. The Ax-1 crew continues to work through previously planned mission activities. The Ax-1 crew and Dragon spacecraft remain healthy.

The departure of Dragon Endeavour from the space station will clear the docking port for the arrival of Dragon Freedom and NASA’s SpaceX Crew-4 astronauts. The earliest potential launch opportunity for the Crew-4 mission is 4:15 a.m. Tuesday, April 26, with additional opportunities Wednesday, April 27, and Thursday, April 28. These launch opportunities are undergoing a more detailed program review to ensure they align with integrated operational timelines. The teams want to provide a two-day gap after Ax-1 return for data reviews from splashdown and to prepare for the Crew-4 launch, including the staging of recovery assets.

The Crew-4 astronauts spent last night at the Kennedy Space Center in Florida rehearsing the countdown to their launch inside the SpaceX Dragon Freedom, the company’s newest crew ship. Overnight, Crew-4 Commander Kjell Lindgren, Pilot Robert Hines with Mission Specialists Jessica Watkins and Samantha Cristoforetti, put on their pressure suits and entered their vehicle conducting a successful dry dress rehearsal. The Falcon 9 rocket, with the Freedom perched atop, stands at Launch Complex 39A.

Expedition 67 crewmates Raja Chari and Tom Marshburn, who are also the SpaceX Crew-3 commander and pilot respectively, spent a little time on Wednesday with their upcoming departure activities. The pair, along with Kayla Barron of NASA and Matthias Maurer of ESA, will wait for the arrival of their Crew-4 replacements before returning to Earth a few days later inside the Dragon Endurance vehicle. The four astronauts had a light-duty day on Wednesday scheduling in some housecleaning tasks.

Over in the Russian segment of the station, cosmonauts Oleg Artemyev and Denis Matveev wrapped up their post-spacewalk activities today stowing their tools and discussing the excursion with specialists on the ground. The duo kicked off a series of spacewalks on April 18 to configure the European robotic arm for operations on the Nauka multipurpose laboratory module. Roscosmos Flight Engineer Sergey Korsakov started his day with electronics and communications maintenance before studying future spacecraft and robotic piloting techniques in the afternoon.

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 on July 8.

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