Russian cosmonauts Oleg Novitskiy and Pyotr Dubrov of Roscosmos concluded their spacewalk at 6:35 p.m. EDT after 7 hours and 54 minutes. It is the first of up to 11 spacewalks to prepare the new Nauka multipurpose laboratory module for operations in space.

Novitskiy and Dubrov completed the major objective for today to connect power cables between the recently arrived Nauka module and the Zarya module to enable the routing of electricity from the U.S. segment of the station to Nauka. Checkouts of the two electrical power cable systems from Zarya to Nauka were successful. They also partially installed one new handrail.

Tasks deferred to a future spacewalk are to install two additional handrails to enable spacewalkers to maneuver to and about Nauka more easily, make the final connection for the ethernet cable the duo partially routed today, deploy a science investigation, jettison the ethernet cable reel following the completion of the connection, and take imagery of the Russian segment of the station.

The duo will continue work during a second spacewalk on Thursday, Sept. 9; coverage on NASA Television, the NASA app, and agency’s website will begin at 10:30 a.m. with the spacewalk expected to begin about 11 a.m. and last about five hours.

This was the 10th spacewalk this year and the 242nd overall in support of space station assembly, maintenance and upgrades. Spacewalkers have now spent a total of 63 days, 15 hours, and 35 minutes working outside the station.

It is the second spacewalk for both cosmonauts, both of whom have now spent a total of 15 hours and 13 minutes spacewalking.

In November 2020, the International Space Station surpassed its 20-year milestone of continuous human presence, providing opportunities for unique research and technological demonstrations that help prepare for long-duration missions to the Moon and Mars and also improve life on Earth. In that time, 244 people from 19 countries have visited the orbiting laboratory that has hosted nearly 3,000 research investigations from researchers in 108 countries and areas.

Expedition 65 Flight Engineers Oleg Novitskiy and Pyotr Dubrov of the Russian space agency Roscosmos began a spacewalk to prepare the new Nauka multipurpose laboratory module for operations in space when they opened the hatch of the Poisk docking compartment airlock of the International Space Station at 10:41 a.m. EDT.

Novitskiy, designated extravehicular crew member 1 (EV1), is wearing a Russian Orlan spacesuit with red stripes, and Dubrov is wearing a spacesuit with blue stripes as extravehicular crew member 2 (EV2).

Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website. Views from a camera on Novitskiy’s helmet are designated with the number 22, and Dubrov’s is labeled with the number 20.

The duo’s primary tasks for today’s spacewalk are to connect power and ethernet cables to the new module and install handrails to enable spacewalkers to maneuver to and about its exterior more easily.

NASA Television coverage of today’s spacewalk with cosmonauts Oleg Novitskiy and Pyotr Dubrov of the Russian space agency Roscosmos is now underway and is also available on the NASA app and the agency’s website.

The crew members of Expedition 65 are preparing to exit the International Space Station‘s Poisk module on the space-facing side of the station’s Russian segment for a spacewalk expected to begin at approximately 10:35 a.m. EDT and last as long as seven hours.

It will be the first of up to 11 spacewalks to prepare the new Nauka multipurpose laboratory module for operations in space. Watch a video animation preview of today’s spacewalk and planned activities at: https://www.youtube.com/watch?v=hfacX6864b4

During the spacewalk today and subsequent spacewalk planned for Sept. 9, the cosmonauts will install handrails on Nauka and connect power, ethernet, and data cables between the recently arrived module and the Zvezda service module. Nauka launched on a Russian Proton-M rocket July 21 from the Baikonur Cosmodrome in Kazakhstan and docked autonomously to the Earth-facing Zvezda port July 29.

This will be the second spacewalk for both Novitskiy and Dubrov; the 242nd spacewalk in support of space station assembly, maintenance and upgrades; and the 10th and spacewalk at the station in 2021.

Cosmonauts Get Ready for Friday Spacewalk, New Science Kicks Off

Cosmonauts Get Ready for Friday Spacewalk, New Science Kicks Off

Two cosmonauts will exit the International Space Station on Friday to begin powering up the new Russian science module. While they prepare today for the excursion, the rest of the Expedition 65 crew focused on new science experiments and reviewed an upcoming U.S. spacewalk.

Russia’s Nauka multipurpose laboratory module, attached to the station since July 29, will be connected to the station’s ethernet and power systems during a spacewalk set to start Friday at 10:35 a.m. EDT. Roscosmos Flight Engineers Oleg Novitskiy and Pyotr Dubrov will exit the Poisk airlock to begin about seven hours of routing and mating cables on the outside of Nauka.

The spacewalking cosmonauts were joined on Thursday by NASA Flight Engineer Mark Vande Hei and Commander Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) for a review of Friday’s spacewalk procedures. Vande Hei will also assist the spacewalkers in and out of their Russian Orlan spacesuits inside the Poisk module.

Novitskiy and Dubrov have another spacewalk scheduled on Sept. 9 to continue outfitting Nauka with handrails and cables. Both spacewalks will be broadcast live on NASA TV, the NASA app, and the agency’s website.

New space investigations recently delivered aboard the SpaceX Cargo Dragon are just getting under way aboard the orbiting lab. NASA Flight Engineer Megan McArthur kicked off the Genes In Space-8 study today to explore how medicines may act differently in microgravity. A student-designed experiment, started today by NASA Flight Engineer Shane Kimbrough, looks at the mating habits of tardigrades living inside mixture tubes and stowed in a NanoRacks research device.

Kimbrough also swapped out science components inside the Fluids Integrated Rack. Hoshide worked in the Electrostatic Levitation Furnace cleaning and removing sample cartridges. Vande Hei installed a new incubator, a temperature controlled device that supports a variety of biology and physics research, in JAXA’s Kibo laboratory module.

The next spacewalk following the Russian excursions is planned for Sept. 12 with Hoshide and Pesquet. The duo reviewed procedures today tasked for the scheduled six-and-a-half hour excursion. They will exit the U.S. Quest airlock to modify the Port-4 (P4) truss structure preparing it for a new Roll-Out Solar Array due to arrive next year aboard the Space Cargo Dragon space freighter.

The Expedition 65 crew continued unloading a variety of cargo including rodents from the SpaceX Cargo Dragon today. The International Space Station residents are also headlong into preparations for two Russian spacewalks and one U.S. spacewalk.

Flight Engineers Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) spent Wednesday morning transferring rodents from the Cargo Dragon into a habitat in the U.S. Destiny laboratory module. The animals are being observed for the Rodent Research Demonstration-1 experiment that is exploring how microgravity affects the healing process.

Space botany is also a critical part of the station research program as scientists learn to support astronauts longer and farther in space. During a break in today’s rodent transfers, Kimbrough serviced petri plates for the new APEX-08 investigation that is studying how plants adapt to space-caused stress.

NASA Flight Engineers Megan McArthur and Mark Vande Hei also partnered together unpacking science gear from Dragon. McArthur installed a new NanoRacks module, recently delivered aboard the U.S. space freighter, during the morning that will soon host science experiments. Vande Hei helped out in the afternoon continuing to unload the more than 4,800 pounds of research, crew supplies and hardware.

Pesquet will join Commander Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) for a spacewalk on Sept. 12 to modify the station’s Port-4 (P4) truss structure. They will install a modification kit that will prepare the P4 for future Roll-Out Solar Array installation work. Hoshide worked Wednesday afternoon cleaning their U.S. spacesuit cooling loops today with assistance from Vande Hei.

The first two spacewalks will be conducted by Roscosmos Flight Engineers Oleg Novitskiy and Pyotr Dubrov. The duo will first exit the Poisk airlock on Friday at 10:35 a.m. EDT to route and mate power and ethernet cables on the Nauka multipurpose laboratory. The second spacewalk will be on Sept. 9 to install handrails and finish the cable work on Nauka. NASA TV will broadcast both excursions live.
