Commander Peggy Whitson will work outside the space station for the ninth time in her career on Friday. She will be joined by Flight Engineer Jack Fischer who will embark on his first spacewalk. The duo will exit the Quest airlock around 8 a.m. EDT for about 6.5 hours of external tasks.
They will replace an avionics box that provides power to science experiments, install a shield on the Pressurized Mating Adapter-3 and rig a new high-definition camera and pair of wireless antennas. NASA TV will broadcast live the 200th spacewalk at the station for assembly and maintenance starting at 6:30 a.m.
Whitson is also in the second week of a study that explores the differences in bone structure on Earth and in space. She swapped bone cell media inside the Microgravity Science Glovebox which is then stowed inside a science freezer. The experiment samples will be returned to Earth on a future SpaceX Dragon mission for analysis by scientists.
The Expedition 51 crew is getting ready for a spacewalk Friday and working on several scientific investigations. Robotics controllers also swapped out a power relay box over the weekend through a complex and innovative robotic procedure.
Astronauts Peggy Whitson and Jack Fischer will exit the International Space Station for a 6.5-hour spacewalk on Friday. The duo will replace an avionics box that routes command and data information to external science experiments. Friday’s spacewalk will be the 200th at the station for assembly and maintenance, the ninth for Whitson and the first for Fischer.
Friday evening and into Saturday, Robotics Ground Controllers maneuvered the Special Purpose Dexterous Manipulator (SPDM) Arms and successfully removed a failed Main Bus Switching Unit-2 and replaced it with a spare. The MBSU in question had stopped communicating telemetry back on April 25 but was still routing power to station systems.
The crew had installed a series of jumpers to power systems connected to the MBSU during the replacement, ensuring no impact to continued station operations. This was the first time an MBSU was swapped out by means other than a spacewalk. Since the successful replacement, the MBSU was powered up and checked out successfully with all station systems back to nominal power configuration.
The five-member crew aboard the International Space Station was back at work Thursday researching how living in space affects the human body. Two of today’s experiments looked at how microgravity weakens bones and alters DNA.
Commander Peggy Whitson joined Flight Engineer Thomas Pesquet for the OsteoOmics bone loss study. The experiment compares bone loss in the free-floating environment of microgravity versus magnetic levitation on Earth and observes the molecular changes that place. Results may improve the health of crews in space and humans on Earth, possibly counteracting bone loss and preventing bone diseases.
Pesquet later checked samples for the Genes In Space experiment that is based on a winning proposal submitted during a student science competition. That study is testing new technology to track how a space mission alters an astronaut’s DNA and impacts their immune system.
The rest of the crew, including NASA astronaut Jack Fischer and cosmonauts Fyodor Yurchikhin and Oleg Novitskiy, split their time between loading a Russian cargo craft, crew orientation and systems maintenance.
The Expedition 51 quintet studied how long-term space missions affect bone loss and explored new ways to exercise in space today. The crew also reviewed emergency procedures and equipment onboard the International Space Station.
Astronauts Peggy Whitson and Thomas Pesquet set up samples today for the OsteoOmics bone study that will last four weeks on the station. Doctors are researching the molecular mechanisms that impact the bones of astronauts living in space. The experiment could lead to therapeutic insights improving the health of astronauts in space and humans on Earth.
New Flight Engineer Jack Fischer performed an ultrasound scan of his leg muscles with assistance from Whitson and remote guidance from ground personnel. The ultrasound data is being collected for the Sprint study that is exploring the benefits of high-intensity, low-volume exercise to maintain muscle, bone and heart functions.
Whitson and Fischer then joined veteran cosmonaut Fyodor Yurchikhin for a couple of hours of emergency training. The trio took note of safety gear locations, followed escape paths to the docked Soyuz vehicles and inspected hatches for proper clearances.
The International Space Station raised its orbit today to get ready for a June crew departure. The first of two orbital reboosts comes just a week after two new crew members arrived to begin their mission with Expedition 51.
Flight Engineers Oleg Novitskiy and Thomas Pesquet will return to Earth June 2 ending the Expedition 51 mission. Expedition 52 will begin and veteran cosmonaut Fyodor Yurchikhin will stay behind with NASA astronauts Peggy Whitson and Jack Fischer waiting for the next crew arrival on July 28.
The current orbiting crew of five Expedition 51 crew members continued more biomedical research and eye checks today. The crew underwent a series of ultrasound scans and eye tests to learn how living in space affects vision. The astronauts are subjects of ongoing studies to help NASA plan missions farther out in space for longer periods of time.
One symptom of living in space for long periods is the pressure that builds up behind astronauts’ eyes due to the upward flow of fluids. Doctors are seeking to counteract this flow after some astronauts have reported vision problems during and after their long-term missions.
NASA astronauts Peggy Whitson and Jack Fischer live-streamed a broadcast from space today using 4K ultra-high-definition technology for the first time. The duo called down to the National Association of Broadcasters in Las Vegas to demonstrate the advanced technology and promote space science and filmmaking.
Expedition 51 worked throughout Wednesday on a variety of microgravity research and spaceship unpacking. The five crew members also conducted vision checks while their newest pair continued getting up to speed on International Space Station systems.
French astronaut Pesquet joined Russian cosmonaut Oleg Novitskiy for ultrasound scans and eye exams in the morning. The two crewmates are participating in a study to understand and offset the headward fluid shifts in space that are known to affect vision.
Pesquet got together at the end of the day with Whitson and Jack Fischer for more eye checks with guidance from doctors on the ground. Whitson also studied how astronauts adapt to touchscreen interfaces. Fischer spent a few hours swapping sample cartridges in a high-temperature furnace lab facility.
Veteran cosmonaut Fyodor Yurchikhin continued offloading cargo from the new Soyuz MS-04 crew ship. Pesquet also transferred new science and crew supplies from the Cygnus resupply ship. Yurchikhin and Fischer are continuing to adapt to living and working aboard the station having been in space less than week.
Expedition 51 Commander Peggy Whitson broke the U.S. record today for most cumulative time living in space, surpassing astronaut Jeff Williams’ record of 534 days set during his four spaceflights. She passed Williams’ mark at 1:27 a.m. EDT.
President Donald Trump called the International Space Station Monday morning and congratulated Whitson on her record-breaking career. Whitson and her newest crewmate NASA astronaut Jack Fischer discussed NASA’s research in space and its plans to go to Mars in the 2030’s.
Before today’s presidential call the Expedition 51 crew members joined together to review their roles and responsibilities in the unlikely event of an emergency aboard the International Space Station. If necessary, they could put on safety gear, evacuate the station into their docked Soyuz vehicles and quickly undock for a ride back to Earth.
The crew is also unloading gear today from two new spaceships that arrived last week. Veteran cosmonaut Fyodor Yurchikhin has been transferring cargo from the Soyuz MS-04 spacecraft he piloted to a docking last Thursday. Whitson and Flight Engineer Thomas Pesquet are working to offload new science experiments and crew supplies that arrived Saturday morning aboard the Cygnus resupply ship.
Using the International Space Station’s robotic Canadarm2, Expedition 51 Flight Engineer Thomas Pesquet of ESA (European Space Agency) and Commander Peggy Whitson successfully captured Orbital ATK’s Cygnus cargo spacecraft at 6:05 a.m. EDT. The space station crew and robotic ground controllers will position Cygnus for installation to the orbiting laboratory’s Earth-facing port of the Unity module.
NASA Television coverage of installation will begin at 7:30 a.m., and installation of the Cygnus spacecraft to the space station is expected to be completed later this morning.

The Expedition 51 crew is waiting for a space delivery mission after welcoming two new crewmates Thursday. Two astronauts are training for a resupply ship’s arrival as two other crew members are getting used to their new home in space.
The Cygnus cargo craft will arrive at the International Space Station early Saturday after a four-day trip to deliver new science experiments and crew supplies. Flight Engineer Thomas Pesquet with assistance from Commander Peggy Whitson will maneuver the Canadarm2 to reach out and capture Cygnus after its final approach. Finally, ground controllers will give the crew a break and remotely control the 57.7 foot robotic arm and install Cygnus to the Harmony module.
NASA astronaut Jack Fischer is adapting to living in weightlessness for the first time, while his crewmate cosmonaut Fyodor Yurchikhin is beginning his fifth mission in space. The pair joined Expedition 51 Thursday morning just six-hours, 10-minutes after blasting off from Kazakhstan in the Soyuz MS-04 spaceship. They will stay in space until September before returning back to Earth with record-setting astronaut Whitson.
Two new crew members are aboard the International Space Station. The hatches on the space station and Soyuz MS-04 opened at 11:25 a.m. EDT, marking the arrival to the orbiting laboratory for NASA astronaut Jack Fischer and Fyodor Yurchikhin of the Russian space agency Roscosmos.
Along with Expedition 51 Commander Peggy Whitson of NASA and Flight Engineers Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency), the arriving crew members will contribute to more than 250 research experiments ongoing aboard the space station, in diverse fields such as biology, Earth Science, human research, physical sciences and technology development.
