The International Space Station welcomed a new cargo craft overnight as mission managers postponed the launch of the SpaceX Crew-7 mission for 24 hours. The Expedition 69 crew members have begun unpacking the new cargo while servicing a variety of science equipment aboard the orbital lab.

Cosmonauts Sergey Prokopyev and Dmitri Petelin went to bed Friday mid-afternoon after monitoring the Roscosmos Progress 85 resupply ship as it docked to the Zvezda service module’s aft port at 11:45 p.m. EDT on Thursday. The duo worked through leak and pressure checks, opened the Progress 85 hatch, then spent the next several hours offloading some of the nearly three tons of food, fuel, and supplies to replenish the lab residents.

As the Roscosmos resupply ship approached the station, four SpaceX Crew-7 crew members in Florida were informed their launch to join the Expedition 69 crew would wait one more day. Liftoff of the SpaceX Dragon Endurance spacecraft atop the company’s Falcon 9 rocket is now scheduled for 3:27 a.m. EDT on Saturday from NASA’s Kennedy Space Center. Mission managers decided to use the extra day to review Dragon’s safety and life support systems.

Crew-7 Commander Jasmin Moghbeli will lead Pilot Andreas Mogensen of ESA (European Space Agency) and Mission Specialists Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) and Konstantin Borisov of Roscosmos, during their flight to the station. The Commercial Crew quartet aboard Endurance will automatically dock to the Harmony module’s space-facing port at 8:39 a.m. on Sunday. Soon after, the foursome will enter the station, greet the Expedition 69 crew, and begin a six-month microgravity research mission.

Meanwhile, the seven station crew members orbiting Earth are all but ready to welcome their four new crewmates. While the two cosmonauts were wrapping up Progress 85 activities and getting ready for bed, the other five lab residents worked on advanced research hardware and investigated ways to treat heart ailments.

NASA Flight Engineers Stephen Bowen and Woody Hoburg worked in the Tranquility module preparing the NanoRacks Bishop airlock for its upcoming depressurization and demating. The Canadarm2 robotic arm will grapple and remove Bishop from Tranquility early next week for an experiment to measure temperature, vibrations, and radiation on external payload sites.

UAE (United Arab Emirates) astronaut Sultan Alneyadi stowed hardware and reconfigured the Microgravity Science Glovebox following an investigation to manufacture superior material structures in space. Flight Engineer Frank Rubio of NASA worked in the Kibo laboratory module swapping samples of stem-cell derived heart micro-tissues inside the Life Science Glovebox. Rubio’s research work may help doctors discover new therapies for space-caused cardiac abnormalities and Earth-bound heart diseases.

The Expedition 69 crew will receive a space delivery late Thursday night and just a few hours before a new crew will launch to the International Space Station. While the orbital residents are getting ready for both missions there was still some time for gene therapy research and lab maintenance tasks.

Two cosmonauts, Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin, will be on duty monitoring the Roscosmos Progress 85 cargo craft during its automated docking planned for 11:50 p.m. EDT. During the morning, the duo practiced on the telerobotically operated rendezvous unit, or TORU, to remotely control an arriving spacecraft in the unlikely event the vehicle was unable to automatically dock. The Progress 85 is carrying three tons of food, fuel, and supplies the cosmonaut duo will begin unpacking about two hours after its arrival. The space freighter will remain docked to the Zvezda service module’s aft port for six months of cargo activities.

About 4 hours after the resupply ship’s arrival, the SpaceX Crew-7 mission will launch from NASA’s Kennedy Space Center to the orbital lab. Liftoff of the SpaceX Dragon Endurance spacecraft with four Commercial Crew members atop the company’s Falcon 9 rocket is scheduled for 3:50 a.m. Friday.

Endurance, commanded by NASA astronaut Jasmin Moghbeli with Pilot Andreas Mogensen of ESA (European Space Agency) and Mission Specialists Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) and Konstantin Borisov of Roscosmos, will automatically dock to the Harmony module’s space-facing port at 2:02 a.m. on Saturday. About two hours later the foursome will enter the station, greet the Expedition 69 crew, and begin a six-month microgravity research mission.

Flight Engineers Stephen Bowen and Woody Hoburg, both from NASA, and Sultan Alneyadi from UAE (United Arab Emirates) prepared for Saturday’s Crew-7 arrival configuring the station for four new crew members. Bowen staged emergency equipment in the orbital lab’s U.S. segment that is standard procedure before a new crew arrives. Hoburg set up a new crew quarters in the Columbus laboratory module. Alneyadi configured computers inside the cupola that will monitor Dragon Endurance’s arrival on Saturday morning.

While the mission preparations were underway, NASA Flight Engineer Frank Rubio focused his time on biotechnology research. He treated cell samples to seek ways to closely mimic the human central nervous system and brain environment for the Neuronix investigation. Results may provide paths for researchers to discover new therapies treating neurological diseases such as Alzheimer’s and Parkinson’s.

On Thursday, Aug. 24, the International Space Station’s Zvezda service module engines were fired for 21.5 seconds, beginning at 11 a.m. EDT to maneuver the complex away from the predicted track of an orbital debris fragment. The maneuver will not affect the rendezvous of the Roscosmos Progress 85 cargo vessel or the launch of NASA’s SpaceX Crew-7 mission.

A cargo craft is orbiting Earth today heading toward the International Space Station as the seven Expedition 69 crew members studied how weightlessness affects cardiac tissue and the digestive system. Meanwhile, a new crew counts down to its launch early Friday.

Three tons of space supplies are packed aboard the Roscosmos Progress 85 cargo craft and on the way to the orbital residents for a delivery scheduled at 11:50 p.m. EDT on Thursday. Station commander Sergey Prokopyev and Flight Engineer Dmitri Petelin will be on duty Thursday night monitoring the Progress 85 when it automatically docks to the Zvezda service module’s aft port. The duo will wait about two hours during standard leak and pressure checks before opening the resupply ship’s hatch and begin unpacking the new food, fuel, and other cargo.

While the cargo activities get underway, the SpaceX Crew-7 mission will launch at 3:50 a.m. on Friday from NASA’s Kennedy Space Center. Four Commercial Crew astronauts will be seated inside the SpaceX Dragon Endurance spacecraft atop the company’s Falcon 9 rocket awaiting a 24-hour trip to their new home in space.

NASA astronaut and Crew-7 Commander Jasmin Moghbeli will be leading Pilot Andreas Mogensen of ESA (European Space Agency) and Mission Specialists Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) and Konstantin Borisov of Roscosmos aboard Endurance during the ride to the station. Endurance, with the quartet inside, will automatically dock to the Harmony module’s space-facing port at 2:02 a.m. on Saturday. The foursome will open the hatch about two hours later, enter the station, greet the Expedition 69 crew, and begin a six-month microgravity research mission.

Meanwhile, the crewmates living in space explored how microgravity affects cardiac cells and the digestive system to benefit humans living on and off the Earth. NASA Flight Engineers Frank Rubio and Woody Hoburg treated samples of stem-cell derived heart micro-tissues on Wednesday in the Kibo laboratory module. The Project EAGLE biology study takes place in Kibo’s Life Science Glovebox and may reveal potential therapies for space-caused cardiac abnormalities and Earth-bound heart diseases.

Prokopyev and Petelin started the day with ultrasound scans after breakfast to observe how the digestive system adapts to weightlessness. Prokopyev then partnered with Flight Engineer Andrey Fedyaev in the afternoon for more tests of the lower body negative pressure suit that may help crew members readjust to Earth’s gravity environment.

Fedyaev will be returning to Earth soon with Hoburg and astronauts Stephen Bowen of NASA and Sultan Alneyadi of UAE (United Arab Emirates). The quartet will enter the SpaceX Dragon Endeavour spacecraft one week after Crew-7 arrives, undock from Harmony’s forward port, and splashdown off the coast of Florida to complete a six-month space mission. During Wednesday afternoon, the four crewmates inspected their SpaceX pressure suits they will wear inside Endeavour when they depart the station for the ride back to Earth.
