Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan concluded their spacewalk at 12:33 p.m. EST. During the six hour and two minute spacewalk, the two astronauts successfully installed a new cooling system for the Alpha Magnetic Spectrometer (AMS).
The crew completed the primary task to install the upgraded cooling system, called the upgraded tracker thermal pump system (UTTPS), completed the power and data cable connection for the system, and connected all eight cooling lines from the AMS to the new system. The intricate connection work required making a clean cut for each existing stainless steel tube connected to the AMS then connecting it to the new system through a process of metalworking known as swaging.
The astronauts also completed an additional task to install an insulating blanket on the nadir side of the AMS to replace the heat shield and blanket they removed during the first spacewalk to begin the repair work. The flight control team on Earth initiated power-up of the system and confirmed it is receiving power and data.
It is the first long day of a very busy several weeks for the space station crew, with two cargo resupply spacecraft launching to the station loaded with science investigations; a SpaceX Dragon is scheduled to lift off at 12:51 p.m. Wednesday, and a Russian Progress is set to launch Friday at 4:34 a.m. Crew members then will be focused on the spacecrafts’ arrivals and associated work. Meanwhile, teams on Earth will evaluate the date for the planned fourth spacewalk to conduct leak checks for the spectrometer’s refurbished cooling lines and complete the work to resume operations of the cosmic ray detector.

Parmitano has now conducted five spacewalks in his career for a total of 26 hours and 53 minutes, and Morgan has logged 39 hours and 32 minutes during six spacewalks since his arrival on the station in July. It was the 11th spacewalk at the station this year. Space station crew members have conducted a total of 224 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 58 days 15 hours and 43 minutes working outside the station.
The six-member Expedition 61 crew is relaxing today and enjoying a belated Thanksgiving meal after an intense week of biology research and spacewalk preparations. A Russian resupply ship also departed the International Space Station this morning as two more space freighters are poised to replenish the orbiting lab. The ISS Progress 73 cargo ship, loaded with trash, undocked from the Pirs Docking Compartment and was deorbited, burning up over the Pacific Ocean.
The four astronauts and two cosmonauts on the orbiting lab were off-duty today sharing a Thanksgiving meal together after working all day during the U.S. holiday. Most of the fixings that dress a turkey on a dining table on Earth were available aboard the station’s galley including cornbread, green beans, mashed potatoes and gravy.
Morgan and Parmitano now turn their attention to Monday’s spacewalk to continue the complex repair job on a cosmic particle detector on the station’s truss. They will be employing complex and innovative repair techniques never performed in space to replace a faulty cooling pump on the Alpha Magnetic Spectrometer. The spacewalkers will set their U.S. spacesuits to battery power at 6:50 a.m. EST on Monday signifying the start of their venture. NASA TV begins its live broadcast at 5:30 a.m.
Cosmonauts Alexander Skvortsov and Oleg Skripochka monitored the Progress 73 resupply ship as it undocked at 4:25 a.m. EST Friday completing its four-month mission at the station. It reentered the Earth’s atmosphere a few hours later and burned up safely over the south Pacific.
Fresh off her fourth spacewalk last Friday, NASA astronaut Christina Koch is packing the Japanese HTV-8 cargo craft with discarded hardware and trash for disposal. Commander Luca Parmitano of ESA (European Space Agency) joined Koch for the cargo transfers today.
Koch and NASA Flight Engineer Jessica Meir will be in the cupola on Friday, Nov. 1 commanding the Canadarm2 robotic arm to release the HTV-8. It will reenter Earth’s atmosphere the following day for a fiery, but safe demise above the Pacific Ocean.
Parmitano and Koch switched roles during the afternoon from space movers to crew medical officers (CMO) examining Meir and NASA Flight Engineer Andrew Morgan. The CMOs operated an ultrasound scanner looking at the cornea, lens and optic nerve inside the eyes of Meir and Morgan.
Koch also researched surface tension in space to understand afflictions such as Alzheimer’s disease and design advanced materials. Meir tended to plants for an ongoing space agriculture study. Morgan installed new life science hardware inside the Kibo lab module’s Saibo biology research rack.
NASA TV coverage has begun of the first all-woman spacewalk in history. Watch on NASA TV and the agency’s website. Expedition 61 Flight Engineers Christina Koch and Jessica Meir of NASA are making final preparations to go outside the International Space Station for today’s tasks to replace a faulty power controller. They are expected to begin their spacewalk at about 7:50 a.m. EDT.
NASA Administrator Jim Bridenstine and former astronaut and acting Associate Administrator for Human Exploration and Operations Ken Bowersox will host a media teleconference at 7:15 a.m. to discuss the historical significance of the event as the agency looks forward to putting the first woman and next man on the Moon by 2024.

Koch is designated extravehicular crew member 1 (EV 1), wearing the suit with red stripes. Meir is designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes. Koch’s helmet camera will carry the number 18, and Meir’s helmet camera will carry the number 11.
The faulty power controller, also known as a battery charge-discharge unit (BCDU), regulates the charge to the batteries that collect and distribute solar power to the orbiting lab’s systems. The unit they are replacing failed to activate following the Oct. 11 installation of new lithium-ion batteries on the space station’s exterior structure.
Although it will be the 221st spacewalk performed in support of space station assembly and maintenance, it is the first to be conducted entirely by women. This will be Koch’s fourth spacewalk and Meir’s first.
This is the second of five battery replacement spacewalks in October. Koch and Morgan performed the first spacewalk on Oct. 6. This series of spacewalks is dedicated to replacing batteries on the far end of the station’s port truss. The existing nickel-hydrogen batteries will be upgraded with newer, more powerful lithium-ion batteries transported to the station aboard the Japanese H-II Transfer Vehicle, which arrived Saturday, Sept. 28. These spacewalks continue the overall upgrade of the station’s power system that began with similar battery replacement during spacewalks in January 2017.
This will be the 220th spacewalk in support of space station assembly and maintenance. Morgan will be designated extravehicular crewmember 1 (EV 1), wearing the suit with red stripes. Koch will be designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes. Morgan’s helmet camera will carry the number 18 and Koch’s helmet camera will carry the number 11.
NASA is preparing to conduct as many as 10 spacewalks in the next three months, a pace that has not been experienced since International Space Station assembly was completed in 2011. Both the crew and the equipment they need has been prepared to meet this demand.
The next spacewalks dedicated to the battery upgrades are scheduled on Oct. 16, 21 and 25.
After completion of the battery spacewalks, the second half of this sequence of spacewalks will focus on repairs to the space station’s Alpha Magnetic Spectrometer. Dates for those spacewalks still are being discussed, but they are expected to begin in November.
All of the U.S. segment crewmembers that will be in space during this time – Christina Koch, Jessica Meir, Andrew Morgan and Luca Parmitano – are expected to take part in conducting the spacewalks.
NASA is providing live coverage on NASA TV and the agency’s website as three people aboard the International Space Station prepare to close the hatches between the station and their spacecraft in preparation for their return to Earth from space. Hatch closure is expected at 12:15 a.m. EDT.
After closing the hatch to their Soyuz MS-12 spacecraft, NASA astronaut and Expedition 60 Flight Engineer Nick Hague, Expedition 60 and Soyuz commander Alexey Ovchinin of the Russian space agency Roscosmos, and visiting astronaut Hazzaa Ali Almansoori of the United Arab Emirates will prepare to undock from the station’s Rassvet module at 3:37 a.m. for their landing in Kazakhstan at 7 a.m.
A Japanese Aerospace Exploration Agency (JAXA) cargo spacecraft is approaching the International Space Station. Watch live coverage on NASA TV and the agency’s website.
Capture of the unpiloted H-II Transfer Vehicle-8 (HTV-8) is expected around 7:15 a.m. The HTV-8 is loaded with more than four tons of supplies, spare parts and experiment hardware for the crew aboard the orbiting laboratory.
Named Kounotori, meaning “white stork” in Japanese, the craft will deliver six new lithium-ion batteries and corresponding adapter plates that will replace aging nickel-hydrogen batteries for two power channels on the station’s far port truss segment. The batteries will be installed through a series of robotics and spacewalks the station’s crew members will conduct later this year.
Expedition 60 Flight Engineer Christina Koch of NASA, backed up by her NASA crewmate Andrew Morgan, will operate the station’s Canadarm2 robotic arm from the station’s cupola to capture the 12-ton spacecraft as it approaches from below. Robotics flight controllers will then take over the operation of the arm to install HTV-8 to the Earth-facing port of the Harmony module where it will spend a month attached to the orbiting laboratory. Flight Engineer Luca Parmitano of ESA (European Space Agency) will monitor HTV-8 systems during its approach to the station.
Coverage of the final installation to Harmony will resume at 9:30 a.m. Robotic ground controllers will install HTV-8 on the Earth-facing side of the Harmony module.
The Japanese Aerospace Exploration Agency (JAXA) cargo spacecraft launched at 12:05 p.m. EDT Sept. 24 (1:05 a.m. Sept. 25 Japan standard time) from the Tanegashima Space Center in southern Japan.
Mission Control in Houston informed the crew aboard the International Space Station that tonight’s launch of the Japan Aerospace Exploration Agency (JAXA) unpiloted H-II Transfer Vehicle-8 (HTV-8) cargo spacecraft was scrubbed due to a fire on or near the launch pad at Tanegashima Space Center. The astronauts are safe aboard the station and well supplied.
More information will be provided as it becomes available.
Fifty years to the day that astronauts Neil Armstrong and Buzz Aldrin stepped on the Moon in a giant leap for humanity, NASA astronaut Andrew Morgan and two fellow crew members arrived Saturday for their mission aboard the International Space Station, where humans have lived and worked continuously for more than 18 years.
The Soyuz MS-13 spacecraft carrying Morgan, Luca Parmitano of ESA (European Space Agency) and Alexander Skvortsov of the Russian space agency Roscosmos launched at 12:28 p.m. EDT July 20 (9:28 p.m. Kazakhstan time) from the Baikonur Cosmodrome in Kazakhstan and has safely reached orbit. At the time of launch, the station was flying about 254 miles over southern Russia between Kazakhstan and Mongolia, 646 miles ahead of the Soyuz as it left the launch pad.
The crew has begun their six-hour trip to the orbital laboratory where they will live and work for their mission. Coverage of the Soyuz docking to the International Space Station will begin on NASA TV and the agency’s website at 6 p.m., with the spacecraft docking expected at 6:50 p.m.
Coverage of the hatch opening between the Soyuz and the space station will begin at 8 p.m.
This morning’s SpaceX Dragon launch was scrubbed due to a drone ship power issue. Launch coverage for the next attempt begins at 2:30 a.m. EDT Saturday, May 4, for a 2:48 a.m. launch. Viewers can watch it unfold on NASA Television and the agency’s website. This cargo delivery will replenish the International Space Station with nearly 5,500 pounds of science, supplies and hardware.
Today onboard the space station, in addition to routine maintenance and housekeeping, mice are keeping the astronauts aboard busy with the Rodent Research-12 investigation. While David Saint-Jacques was occupied cleaning habitats and cameras and restocking food, Nick Hague, in addition to Flight Engineers Anne McClain and Christina Koch, spent time calibrating Mass Measurement Devices and establishing baseline readings.
Saint-Jacques and Hague spent some time to reviewing training and procedures for when they command the Canadarm2 robotic arm to capture the Dragon cargo craft at the International Space Station, which is now scheduled for Monday, May 6, at 7 a.m. following a May 4 launch.
Mice could be key to studying immune response in humans. Spaceflight is known to affect immunity, but there’s little research that has been conducted to see how, in fact, humans would respond to a challenge to the body’s immunity in space. Since a mouse’s immune system parallels that of humans, these animal models enable us to learn and understand how astronaut health can be sustained in microgravity.
