Space Research Keeps Crew Busy Before Cygnus Arrival

A wide variety of research kept the Expedition 69 crew busy aboard the International Space Station on Thursday. In the meantime, the orbital residents will welcome a U.S. cargo craft on Friday then turn their attention to a spacewalk next week.

Four astronauts from NASA and the UAE (United Arab Emirates) were back to work following a day off on Wednesday. The quartet had its hands full on Thursday studying how microgravity affects biology, physics, and robotics.

Flight Engineer Stephen Bowen serviced blood samples to assess how the immune system changes in weightlessness. Flight Engineer Frank Rubio swapped samples inside the Materials Science Laboratory, a research facility designed to discover new applications for existing materials and new or improved materials. Flight Engineer Woody Hoburg monitored the Astrobee robotic assistants that were controlled by student-written algorithms in support of the Astrobee-Zero Robotics competition for youth. Astronaut Sultan Alneyadi worked throughout the day on life support maintenance before familiarizing himself with the BioFabrication Facility, a 3D biological printer.

After the science work, all four flight engineers joined each other and called down to the next crew to visit the station, SpaceX Crew-7, and discussed the crew swap targeted for the end of the month. Finally, the foursome wrapped up its day with a conference with mission controllers to discuss Cygnus’ arrival on Friday.

Cygnus is due to be captured at 5:55 a.m. EDT on Friday when Hoburg commands the Canadarm2 robotic arm to reach out and grapple the U.S. resupply ship. Rubio will be backing up Hoburg monitoring Cygnus as it arrives packed with over 8,200 pounds of science and supplies. Cygnus began its trip to the station after launching at 8:31 p.m. on Tuesday from NASA’s Wallops Flight Facility in Virginia.

Just five days after Cygnus arrives, Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin will exit the Poisk airlock in their Orlan spacesuits for the year’s 10th spacewalk. They have been reviewing procedures this week for when they install micrometeoroid orbital debris shields and relocate hardware on the outside of the orbital lab on Aug. 9.

The duo from Roscosmos took a break from spacewalk preparations today and studied how living in space affects digestion and ways future crews may pilot planetary spacecraft and robots. Flight Engineer Andrey Fedyaev also participated in the space digestion study before attaching electrodes to himself for a 24-hour session measuring his heart activity and blood pressure.

Expedition 69 is awaiting an orbiting U.S. cargo craft carrying over 8,200 pounds of science and supplies for delivery on Friday. The International Space Station’s residents split their day on Wednesday as four astronauts took the day off while three cosmonauts prepared for a spacewalk next week.

Northrop Grumman’s Cygnus space freighter is orbiting Earth racing towards the orbital lab after its successful launch from Virginia at 8:31 p.m. EDT on Tuesday. NASA Flight Engineers Woody Hoburg and Frank Rubio will be on duty Friday morning when Cygnus begins its slow, methodical arrival for capture. Hoburg will command the Canadarm2 robotic arm to reach out and grapple Cygnus at 5:55 a.m. after its final approach on Friday. Rubio will back up Hoburg monitoring Cygnus and its telemetry as it nears the space station.

Mission controllers on the ground will remotely take control of the Canadarm2 after Cygnus’ capture and install it to the Unity module’s Earth-facing port about two hours later.  Cygnus is scheduled to end its stay at the orbital lab at the end of October.

Both astronauts along with NASA Flight Engineer Stephen Bowen and UAE (United Arab Emirates) Flight Engineer Sultan Alneyadi relaxed Wednesday setting some time aside for their daily workouts. The quartet will get back to work on Thursday with a research schedule filled with life science, materials physics, and robotics. The foursome will have one more Cygnus conference with mission controllers on the ground, then get a good night’s sleep before beginning a full day of cargo activities.

Next week, two cosmonauts are scheduled to begin the year’s tenth spacewalk. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin are due to exit the Poisk airlock on Aug. 9 to install micrometeoroid orbital debris shields and relocate hardware. The duo spent Wednesday reviewing the upcoming spacewalk procedures and configuring their Orlan spacesuits.

Flight Engineer Andrey Fedyaev worked Wednesday photographing the condition of Earth’s forests using a high-power camera. The first-time space flyer, who also joined Prokopyev and Petelin for the spacewalk review, will be in the Nauka science module at the controls of the European robotic arm assisting the spacewalkers next week.
