ESA, NASA Astronauts Suit Up for Navigation, Science Maintenance Spacewalk

NASA is streaming live coverage as two astronauts prepare for a spacewalk outside the International Space Station. The spacewalk is scheduled to begin at approximately 8:30 a.m. EDT and last about six and a half hours. Watch online at: https://www.nasa.gov/live

NASA astronaut Jessica Meir and ESA (European Space Agency) astronaut Sophie Adenot will exit the station’s Quest airlock to replace a retroreflector on the forward port of the space station’s Harmony module to support spacecraft navigation during rendezvous and docking operations.

After installing the reflector, the crew will work to install jumper cables for the data-relay systems, prepare the Alpha Magnetic Spectrometer’s radiator for future maintenance, and replace a high-definition camera on the station’s truss.

Adenot will serve as spacewalk crew member 1 and will wear a suit with red stripes. Meir will serve as crew member 2 and will wear an unmarked suit.

This will be Meir’s seventh spacewalk and Adenot’s third. The excursion also marks the 284th spacewalk supporting space station assembly, maintenance, and upgrades.

Expedition 75 is Go for Tuesday’s Navigation and Science Maintenance Spacewalk

Astronauts Sophie Adenot of ESA (European Space Agency) and Jessica Meir of NASA will exit the International Space Station after setting their spacesuits to battery power at 7:30 a.m. EDT on Tuesday, Sept. 1, signifying the beginning of their spacewalk. NASA+ and a variety of other platforms will stream live spacewalk coverage beginning at 6 a.m.

The spacewalkers will spend about six-and-a-half hours in the vacuum of space replacing a spacecraft navigational aid, preparing a cosmic particle detector for future upgrades, installing jumper cables to boost data-relay systems, and other tasks. This will be Meir’s seventh spacewalk, Adenot’s third, and the 284^th at the orbital outpost since 1998.

The Expedition 75 crew finalized preparations on Monday for the fourth spacewalk in a month outside the orbital outpost. Adenot and Meir reviewed their spacewalk procedures, prepared their spacesuits, and organized their tools inside the Quest airlock throughout Monday. The duo also joined NASA flight engineers Anil Menon and Jack Hathaway and studied the Canadarm2 robotic arm procedures necessary to support Tuesday’s spacewalk.

Menon will operate the Canadarm2 and guide Meir, attached to its latching end effector by an articulating portable foot restraint, to the worksites along the orbital outpost’s starboard truss structure. Adenot will remain tethered to the station translating on her own to the worksites. Hathaway will monitor the external activities ensuring both spacewalkers stay safe and accomplish their tasks. Menon and Hathaway also will assist the spacewalkers in and out of their spacesuits inside Quest.

The station’s three cosmonauts focused on their contingent of Roscosmos science and maintenance duties on Monday. Flight engineers Pyotr Dubrov and Anna Kikina worked together inside the Zvezda service module and tested communications between the docked Progress 94 cargo craft and the tele-operated robotic unit, or TORU. The TORU would be used to remotely control a Roscosmos spacecraft in the unlikely event its automated rendezvous and docking system failed.

Dubrov also repaired and tested ethernet cables while Kikina worked on electronics and ventilation maintenance. Flight engineer Andrey Fedyaev transferred water from the Progress 94 into station water tanks then jogged on Zvezda’s treadmill while attached to electrodes for a physical fitness test.

NASA, SpaceX Adjust Crew-13 Launch Date

NASA and SpaceX are adjusting the launch date for the agency’s Crew-13 mission to the International Space Station to address an oxidizer leak on Dragon’s propulsion system which was detected during standard prelaunch spacecraft processing. Joint NASA and SpaceX teams are performing additional tests and data review and will complete any necessary rework prior to launch. A new target date will be announced once available.

NASA astronauts Jessica Watkins and Luke Delaney will serve as spacecraft commander and pilot, respectively. They will be joined by CSA (Canadian Space Agency) astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov, who will serve as mission specialists. After arriving at the orbiting laboratory, Crew-13 will become members of the space station’s Expedition 75. The crew will enter quarantine about two weeks prior to flight from the agency’s Johnson Space Center in Houston.

Crew-13 will lift off aboard SpaceX’s Dragon spacecraft on the company’s Falcon 9 rocket from Space Launch Complex 40 from Cape Canaveral Space Force Station in Florida..

U.S. President Speaks to Expedition 75 Crew after Awarding Artemis II Crew

President Donald J. Trump awarded the Congressional Space Medal of Honor on Friday at NASA’s Johnson Space Center in Houston to the four‑member Artemis II crew that flew around the Moon in April. During the event, the president also signed an executive order establishing the nation’s first U.S. Space Academy, which will be led by NASA.

Following the ceremony, the president stopped by the Mission Control Center at Johnson and spoke with the Expedition 75 crew aboard the International Space Station as they took a short break from science and exercise research and preparations for next week’s spacewalk.

Flight engineer Sophie Adenot of ESA (European Space Agency) and station commander Jessica Meir of NASA organized the tools they will use during a spacewalk beginning at 7:30 a.m. EDT on Tuesday, Sept. 1. Adenot and Meir also inspected spacesuit components and tethers inside the Quest airlock. NASA flight engineers Anil Menon and Jack Hathaway cleaned the spacesuit cooling loops that keep the suits thermally conditioned and astronauts comfortable during a spacewalk.

Earlier, Adenot pedaled on an exercise cycle while wearing a sensor-packed packed vest and headband measuring her heart rate, breathing rate, and blood pressure. Menon and Hathaway relocated a sample processor and a science freezer as part of scientific maintenance. Meir reviewed her upcoming spacewalking tasks on a computer using 3D animation software.

Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina took turns pedaling on the station’s exercise cycle while attached to electrodes and breathing gear for a routine physical fitness test. Roscosmos flight engineer Andrey Fedyaev synchronized station cameras to Greenwich Mean Time then photographed and videotaped his crewmates as they worked during their shift on Friday.

Spacewalk Preps, Biomedical Science as Station Boosts Orbit on Thursday

Preparations are ongoing for a spacewalk next week to continue external maintenance on the International Space Station. The Expedition 75 residents are also keeping up biomedical research while maintaining orbital outpost systems. Also, a U.S. cargo craft fired it thrusters on Thursday boosting the station’s orbit.

Flight engineer Sophie Adenot of ESA (European Space Agency) and station commander Jessica Meir of NASA are studying the procedures they will use when they conduct a spacewalk scheduled for 7:30 a.m. EDT on Tuesday, Sept. 1. Adenot and Meir will spend about six-and-a-half hours in the vacuum of space replacing a spacecraft navigational aid, preparing a cosmic particle detector for future upgrades, installing jumper cables to boost data-relay systems, and other tasks.

The astronauts joined NASA flight engineers Anil Menon and Jack Hathaway during the procedure reviews on Thursday and called down to mission controllers to discuss details and answer questions for next week’s spacewalk. Menon, along with his three crewmates, also studied the Canadarm2 robotic arm procedures he will use to maneuver Meir as she conducts her spacewalking tasks.

Life science was booked into the crew’s schedule on Thursday helping doctors continuously monitor crew health to detect potential space-caused issues and ensure a successful long-duration spaceflight. Meir scanned Menon’s jugular veins using the Ultrasound 3 device and measured his blood pressure as researchers on the ground monitored in real time. Adenot exercised wearing the EasyMotion-2 suit that sends electrical impulses and triggers muscle contractions to supplement a space workout. Hathaway took inventory of medical supply kits inside the Human Research Facility-1 and Human Research Facility-2 racks.

Roscosmos cosmonaut Anna Kikina wrapped up a 24-hour monitoring session and removed electrodes that tracked her heart rate and blood pressure while she worked and slept. Flight engineer Pyotr Dubrov spent his shift on life support maintenance replacing components inside the Vozdukh carbon dioxide removal device. Flight engineer Andrey Fedyaev started his shift on computer hardware and firmware updates. At the end of the day, Meir joined Fedyaev and scanned his veins with the Ultrasound 3 for more insight into microgravity’s effect on blood flow.

Northrop Grumman’s Cygnus XL cargo spacecraft fired its thrusters for 20 minutes, 43 seconds today while berthed to the Unity module lifting the International Space Station’s orbit. The orbital reboost places the orbiting lab at the correct altitude for the rendezvous and docking of the Progress 96 resupply ship due to launch in early September.
