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.

United Launch Alliance’s (ULA) Atlas V rocket is assembled in preparation for Boeing’s Orbital Flight Test-2 (OFT-2) launch to the International Space Station as part of NASA’s Commercial Crew Program.

Engineers in ULA’s Vertical Integration Facility (VIF) used large cranes to assemble the stages of the rocket in an upright position on its mobile launch platform, which will carry the Atlas V and Starliner from the VIF to the pad for launch.

To verify the rocket is ready to launch, technicians will soon power the Atlas V to test flight controls, check the engine steering profiles, and conduct a combined systems test.

The 172-foot-tall rocket will be fully completed when the Starliner is mounted aboard the Atlas V. A ULA payload transporter will move the capsule from Boeing’s Commercial Crew and Cargo Processing Facility (C3PF) at the Kennedy Space Center to the nearby VIF for attachment.

The Atlas V will propel Starliner off the pad on 1.6 million pounds of thrust on its second uncrewed flight test from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida no earlier than July 30.

As Boeing’s second uncrewed flight for NASA’s Commercial Crew Program, OFT-2 will serve as an end-to-end flight test to prove the Atlas V rocket and Starliner are ready for regular missions launching astronauts to and from the space station.

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.

NASA and SpaceX have adjusted target launch and return dates for upcoming crew missions to and from the International Space Station based on visiting vehicle traffic.

NASA’s SpaceX Crew-3 mission now is targeting launch no earlier than Sunday, Oct. 31, with NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron and ESA (European Space Agency) astronaut Matthias Maurer. Crew-3 will launch on a new Crew Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to begin a six-month science mission at the space station.

Crew-3 astronauts will arrive at the space station for a short handover period with the Crew-2 astronauts and other crew members on Expedition 66. Crew-2 NASA astronauts Shane Kimbrough and Megan McArthur, JAXA (Japan Aerospace Exploration Agency) astronaut Aki Hoshide, and ESA astronaut Thomas Pesquet are targeting early-to-mid November for a return to Earth inside Crew Dragon Endeavour off the coast of Florida.

Following Crew-3, the next crew rotation mission is targeted for no earlier than mid-April 2022 with the partner spacecraft and launch vehicle to be determined at a later date.

NASA’s Commercial Crew Program is working with industry through a public-private partnership to provide safe, reliable, and cost-effective transportation to and from the International Space Station, which will allow for additional research time and will increase the opportunity for discovery aboard humanity’s testbed for exploration. The space station remains the springboard to space exploration, including future missions to the Moon and eventually to Mars.

NASA and Boeing are targeting 2:53 pm EDT Friday, July 30, for the launch of the company’s Starliner uncrewed Orbital Flight Test-2 (OFT-2) to the International Space Station. The updated launch target is supported by the station’s visiting vehicle schedule, Starliner readiness, and the availability of the United Launch Alliance Atlas V rocket.

“NASA and Boeing have done an incredible amount of work to get to this point,” said Steve Stich, Commercial Crew Program manager. “Our teams are ready for this important mission due to the coordinated efforts of many, including United Launch Alliance, NASA’s Launch Services Program, and the U.S. Space Force, which enabled us to establish this launch opportunity. We are looking forward to a successful OFT-2 mission.”

Boeing recently completed end-to-end testing of Starliner’s fight software by flying a five-day simulated OFT-2 mission to the station. The company will continue supporting NASA’s post-test reviews. All actions recommended by the NASA-Boeing Joint Independent Review Team following Starliner’s uncrewed first flight test in December 2019 are complete and pending closure by NASA.

Boeing also will continue processing hardware for its first flight of astronauts – the Crew Flight Test – until mid-summer. OFT-2 launch activities, including loading cargo and fueling the spacecraft are scheduled to begin around this time.

A launch on July 30 would lead to rendezvous and docking with the space station on the evening of Saturday, July 31.

NASA and SpaceX have decided to move Crew-1’s undocking and splashdown from Friday, April 30, and Saturday, May 1, respectively, following a review of the forecast weather conditions in the splashdown zones off the coast of Florida, which continue to predict wind speeds above the return criteria. Mission teams from NASA and SpaceX will meet again on Friday to further review opportunities for the safe return of Crew-1. Crew Dragon is in great health on the space station, and teams will continue to look for the optimal conditions for both splashdown and recovery.

Commander Akihiko Hoshide is leading the Expedition 65 crew and will stay in space until October with his Crew-2 crewmates Shane Kimbrough and Megan McArthur and Thomas Pesquet. Also staying behind on the orbital lab are Soyuz MS-18 crewmates Mark Vande Hei of NASA and Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov.

All 11 of the orbital residents stayed busy today with human research studies, lab maintenance, and emergency gear training as the Crew Dragon departure activities were under way.

The station was teeming with science on Thursday with the crew collecting and stowing urine samples, conducting behavioral research, and exploring how affects grip and movement. Fuel bottles supporting combustion experiments were swapped out while new hardware was installed to activate a high-performance space computer study.
