Astronauts Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency are wrapping up final transfers of completed science experiments in Dragon today. The duo is loading science samples from several experiments for return to Earth, where they will quickly be delivered to investigators around the country for analysis.
Engineers on the ground are testing communications and control gear that will be used to monitor and command Dragon after its release from the station. Robotics controllers are also powering up the Canadarm2 robotic arm today to grapple Dragon before its removal from the Harmony module.
The SpaceX Dragon cargo craft is in its final week attached to the International Space Station’s Harmony module. Meanwhile, robotics experts on the ground and the crew aboard the lab are working a wide variety of science activities today.
The Dragon space freighter has nearly completed its cargo mission to replenish the orbital laboratory after delivering over 5,600 pounds of science and supplies Dec. 8. Dragon will return to Earth Jan. 10 for retrieval in the Pacific Ocean loaded with completed science experiments and used hardware for analysis.
Three people from the U.S., Canada and Russia are orbiting Earth today getting ready to observe Christmas and experience New Year’s Eve from space aboard the International Space Station. Back on Earth, another three station crew members have returned to their home bases just 24 hours after completing a 197-day mission aboard the orbital lab.
The first time three humans spent Christmas in space was 50 years ago in 1968 during Apollo 8 and was also the first time a crew orbited the Moon. This Christmas astronauts Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency with cosmonaut Oleg Kononenko of Roscosmos will be soaring about 250 miles above the Earth’s surface in a much larger spacecraft. The Expedition 58 trio will share a traditional meal aboard the orbital lab, share gifts and call down to family during their off-duty day.
Kononenko is beginning his fourth mission on the station and will spend his second Christmas in space. McClain and Saint-Jacques are getting used to life in space for the first time and will return to Earth in June with Kononenko.
NASA astronaut Serena Auñón-Chancellor returned to Houston late Thursday just one day after landing in Kazakhstan wrapping up her six-and-a-half month stay aboard the orbital lab. She parachuted to Earth inside the Soyuz MS-09 spacecraft with her Expedition 57 crewmates Alexander Gerst of ESA (European Space Agency) and Sergey Prokopyev of Roscosmos.
Auñón-Chancellor and her crewmates, Expedition 57 Commander Alexander Gerst of ESA (European Space Agency) and Soyuz commander Sergey Prokopyev, launched June 6 and arrived at the space station two days later to begin their mission.
During the 197 days, they circled the globe 3,152 times, covering 83.3 million miles. This was the first flight for Auñón-Chancellor and Prokopyev and the second for Gerst, who – with a total of 362 days in orbit – now holds the flight duration record among ESA astronauts.
For the last 16 days of her mission, Auñón-Chancellor was joined by fellow NASA astronaut Anne McClain, marking the first time in which the only two U.S. astronauts on a mission were both women.
Prokopyev completed two spacewalks totaling 15 hours and 31 minutes. He and Oleg Artemyev of Roscosmos launched four small technology satellites and installed an experiment during a spacewalk Aug. 15. Then during a 7 hour, 45 minute spacewalk Dec. 11, he and Oleg Kononenko of Roscosmos retrieved patch samples and took digital images of a repair made to the habitation module of the Soyuz MS-09 in which the Expedition 57 trio rode home. The space station crew located and, within hours of its detection, repaired a small hole inside the Soyuz in August. The spacecraft was thoroughly checked and deemed safe for return to Earth.
Auñón-Chancellor will return home to Houston, Gerst will return to Cologne, Germany, and Prokopyev will return to Star City, Russia, following post-landing medical checks and research activities.
Deorbit burn is scheduled for approximately 11:10 p.m., with landing in Kazakhstan targeted for 12:03 a.m. Thursday (11:03 p.m. local time). NASA will resume coverage on TV and online at 10:45 p.m. for deorbit burn and landing.
At the time of undocking, Expedition 58 began aboard the space station under the command of Roscosmos’ Oleg Kononenko. Along with his crewmates Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency, the three-person crew will operate the station for a little more than two months.
Nick Hague and Christina Koch of NASA and Alexey Ovchinin of Roscosmos will launch aboard Soyuz MS-12 Feb. 28, from the Baikonur Cosmodrome in Kazakhstan, to join their fellow crewmates following a six-hour journey. Expedition 59 will begin when the new trio docks to the space station.
The Expedition 57 commander handed over control of the International Space Station today in a traditional ceremony. He and two of his crewmates will then head back to Earth Wednesday just in time for the holidays.
Gerst and Flight Engineers Serena Auñón-Chancellor and Sergey Prokopyev are winding down their 197-day mission in space. The trio will undock from the Rassvet module inside the Soyuz MS-09 spacecraft Wednesday at 8:40 p.m. and parachute to a landing in Kazakhstan about three-and-a-half hours later.
Prokopyev will command the Soyuz flight back to Earth tomorrow flanked by Gerst and Auñón-Chancellor. Today he is packing and readying the spacecraft for the departure. The undocking and landing activities will be broadcast live on NASA TV.
There was still time for science on the orbital lab today as Gerst explored how astronauts manipulate objects in space. Results could improve the design of space habitats and impact neurology patients on Earth. He also joined Auñón-Chancellor for ultrasound scans and blood sample collections as they wrap up their human research studies.
Half of the Expedition 57 crew is getting ready to depart International Space Station while the other half is getting used to life on orbit. Amidst those preparations, all six space residents are researching what microgravity does to their bodies while keeping the orbital lab in tip-top shape.
Commander Alexander Gerst continues unpacking the Space Dragon cargo craft today with its near 5,700 pounds of science, supplies and hardware. The German astronaut from ESA (European Space Agency) is also packing the Soyuz MS-09 crew ship that will take him and two crewmates home next week. He’ll parachute to a landing aboard the Soyuz in Kazakhstan Dec. 20 at 12:03 a.m. EST with fellow crew members Serena Auñón-Chancellor and Sergey Prokopyev after 197 days in space.
Auñón-Chancellor spent Thursday working with a variety of research gear supporting space biology. She processed research samples today in the NanoRacks Plate Reader that enables pharmaceutical and biotechnology science in space. She also stowed biological samples in a science freezer for a cellular adaptation study.
The newest trio aboard the station that arrived last week are hard at work today on human research and getting up to speed on station systems. Flight Engineers Anne McClain and David Saint-Jacques collected blood and urine samples to be analyzed for the Biochemical Profile space adaptation study. The duo also scheduled some time today to get used to life in space. Four-time station cosmonaut Oleg Kononenko joined Prokopyev for more spacesuit maintenance after Tuesday’s spacewalk.
Cosmonauts Oleg Kononenko and Sergey Prokopyev performed routine maintenance on their Russian Orlan spacesuits after a seven-hour, 45-minute spacewalk to inspect the Soyuz MS-09 crew ship docked to the station. The duo took detailed photos and captured video of some of the sealant on the outer hull of the Habitation Module used in the repair of a hole discovered inside the vehicle in August.
The other four orbital residents also put in a good night’s sleep after supporting the eighth spacewalk at the station this year. The quartet moved headlong into human research and departure preps after waking up a few hours later than usual today.
Alexander Gerst and Serena Auñón-Chancellor drew their own blood samples today and processed them in the Human Research Facility’s centrifuge. The samples were then coagulated and stowed in a science freezer for later analysis. The Biochemical Profile is a long-running study on astronauts and is providing insight into the human body’s adaptation to living in space.
Gerst is also packing the Soyuz spacecraft that will take him, Auñón-Chancellor and Prokopyev back to Earth Dec. 19. This is the same spaceship that was inspected Tuesday by the two Russian spacewalkers.
The station’s newest astronauts Anne McClain and David Saint-Jacques are still getting used to their new home in space. The pair also went about the day working on a variety of maintenance and research. McClain strapped on an armband monitoring how her body adapts to orbiting Earth 16 times a day after setting up research hardware for two separate experiments. Saint-Jacques deployed over a dozen radiation monitors throughout the station today before some light plumbing work with Gerst in the orbital restroom.
During the spacewalk, the two examined the external hull of the Russian Soyuz MS-09 spacecraft attached to the space station, took images, and applied a thermal blanket. They also retrieved science experiments from the Rassvet module before heading back inside.
Prokopyev, NASA astronaut Serena Auñón-Chancellor, and ESA (European Space Agency) astronaut Alexander Gerst are scheduled to depart the station in the Soyuz MS-09 at 8:42 p.m. Dec. 19, returning home to Earth after a six-and-half-month mission.
Kononenko, on his fourth spacewalk today, is designated extravehicular crew member 1 (EV1), and is wearing a spacesuit bearing red stripes. Prokopyev, on his second spacewalk, is wearing blue stripes and is designated extravehicular crew member 2 (EV2).
Coverage of the spacewalk continues on NASA Television and the agency’s website.
