One spacewalk down, two more to go before next weekend. A U.S. and a Japanese astronaut will go on the next spacewalk Jan. 29 followed by two cosmonauts on Feb. 2.
Flight Engineers Mark Vande Hei and Norishige Kanai will put on their U.S. spacesuits early next week and exit the Quest airlock to wrap up maintenance on the Canadarm2. The duo will spend about six and a half hours wrapping up work from Tuesday’s spacewalk on swapping a degraded Latching End Effector from the Canadarm2. The spacewalkers will start their excursion Monday at 7:10 a.m. EST and NASA TV coverage will begin at 5:30 a.m.
Cosmonauts Anton Shkaplerov and Alexander Misurkin are also preparing for their next spacewalk set for next Friday when they open the Pirs docking compartment hatch at 10:34 a.m. The veteran station residents will don their Russian Orlan spacesuits for a near six-and-a-half-hour spacewalk outside the International Space Station’s Russian segment. The duo will retrieve science samples exposed to outer space and install a high gain antenna on the rear of the Zvezda service module. NASA TV coverage starts 9:45 a.m.
Both excursions come in the wake of Tuesday’s spacewalk with astronauts Vande Hei and Scott Tingle lasting seven hours and 24 minutes. The two astronauts replaced a Latching End Effector (LEE) on the station’s robotic arm, Canadarm2.
In the midst of the busy spacewalk work, the Expedition 54 crew has been conducting science to understand how living in space affects the human body. Vande Hei is exploring how station lighting affects crew sleep while astronaut Scott Tingle looked at microgravity’s impacts on the brain. Flight Engineer Joe Acaba explored using a special strain of bacteria to support long-term life support systems on future spacecraft.
The International Space Station has been orbiting Earth for 7,000 days as of today Friday, Jan. 19, 2018. The first module, the Russian Zarya cargo module, launched to space in November of 1998. The first crew arrived at the young three-module orbital laboratory in November of 2000.
54 crews and 205 spacewalks later, the current six-member Expedition 54 crew is gearing up for a pair of spacewalks on Jan. 23 and 29. NASA astronaut Mark Vande Hei will lead both spacewalks with Flight Engineer Scott Tingle joining him on the first spacewalk. Japanese astronaut Norishige Kanai will join Vande Hei for the second spacewalk.
All three astronauts were joined today by Flight Engineer Acaba for a spacewalk procedures review with specialists on the ground. The spacewalking trio will be swapping and stowing robotics parts to maintain the upkeep of the Canadarm2 robotic arm. Both spacewalks will start each day at 7:10 a.m. EST with live NASA Television coverage beginning at 5:30 a.m.
The two cosmonauts aboard the space station, Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov, conducted regularly scheduled eye checks today. The veteran orbital residents worked with doctors on the ground using a fundoscope to view the interior of the eye. Crew members aboard the station participate in regular eye exams to understand how living in space affects vision.
The Cygnus resupply ship is in its final week at the International Space Station and two astronauts are training for its departure on Monday. Meanwhile, a leg muscle study and CubeSat deployment operations are wrapping up today.
The duo will be inside the cupola commanding the Canadarm2 to release Cygnus back into Earth orbit on Dec. 4. Following its departure from the station, Cygnus will stay in orbit until Dec. 18 before re-entering the Earth’s atmosphere for a fiery demise over the Pacific Ocean.
Commander Randy Bresnik and cosmonaut Sergey Ryazanskiy are completing a final run of the Sarcolab-3 experiment today. That research is observing how leg muscles adapt to microgravity using magnetic resonance imaging and ultrasound devices.
Finally, a satellite deployer that ejected a set of CubeSats last week, has been brought back inside the Kibo lab module. One of the CubeSats deployed, the EcAMSat that was delivered aboard Cygnus, is now orbiting Earth researching how the E. coli pathogen reacts to antibiotics in space.
The Expedition 53 crew is working out on a new exercise device today and testing new lights for their impact on health. Back on Earth, a new resupply rocket stands at its launch pad ready for a Saturday launch to the International Space Station.
Astronauts Joe Acaba and Mark Vande Hei worked out on the new Mini-Exercise Device-2 (MED-2) this morning performing dead lifts and rowing exercises. The duo tested its ability to provide reliable, effective workouts despite its smaller size to increase the habitability of a spacecraft.
Vande Hei is also analyzing the station’s new solid-state light-emitting diodes that are replacing older fluorescent lights. He conducted a series of tests throughout the day to determine how they impact crew sleep patterns and cognitive performance.
The Orbital ATK Cygnus cargo craft is encapsulated inside the Antares rocket and now stands vertical at the launch pad at Wallops Flight Facility in Virginia. Cygnus is due to launch Saturday at 7:37 a.m. EDT with about 7,400 pounds of new science experiments and fresh supplies for the Expedition 53 crew.
Cygnus will unfurl its cymbal-like UltraFlex solar arrays less than two hours after launch as it begins a two-day trip to the International Space Station. Astronaut Paolo Nespoli will command the Canadarm2 from the Cupola to grapple Cygnus when it arrives Monday morning at 5:40 a.m. Commander Randy Bresnik will back up Nespoli and monitor the approach and rendezvous.
Two astronauts are training for Monday’s planned arrival of Orbital ATK’s newest Cygnus cargo craft dubbed the S.S. Eugene Cernan. The crew is also analyzing the International Space Station’s atmosphere and studying how crew performance adapts to microgravity.
Orbital ATK is counting down to a Veteran’s Day launch of its Cygnus spacecraft atop an Antares rocket from Wallops Flight Facility in Virginia. The rocket is scheduled to blast off Saturday at 7:37 a.m. EST with about 7,400 pounds of science gear and crew supplies packed inside Cygnus.
Commander Randy Bresnik and Flight Engineer Paolo Nespoli are training today to capture Cygnus with the Canadarm2 robotic arm. Nespoli will command the Canadarm2 to grapple Cygnus at 5:40 a.m. Monday when it reaches a point about 10 meters from the station. Bresnik will back up Nespoli and monitor the spacecraft’s approach and rendezvous.
Astronaut Mark Vande Hei has been helping doctors this week understand the risk of living inside the closed environment of a spacecraft for the Airway Monitoring study. He set up gear to analyze the air in the space station for dust and gases that could inflame an astronaut’s respiratory system. Results will help doctors improve crew health as NASA plans human missions farther and longer into space.
Nespoli started his day studying how floating in space impacts interacting with touch-based technologies and other sensitive equipment. Observations from the Fine Motor Skills study may influence the design of future spaceships and space habitats.
Routine—and not-so-routine—housekeeping duties continue for Expedition 53 aboard the International Space Station in preparation for an upcoming Orbital ATK 8 (OA-8) commercial launch targeted for Nov. 11.
The crewmates prepared the Permanent Multipurpose Module rack fronts to accept cargo by moving smaller items off and staging them for disposal. During OA-8 cargo operations, the items marked for disposal will be swapped with new cargo arriving aboard OA-8.
During Orbital ATK’s eighth Cygnus resupply mission, the cargo craft will make a nine-minute ascent to space and then begin a two-day trek to the space station. Upon arrival, it will captured by Canadarm2 and installed for a month-long stay. Tonight, ground teams will reboost the station using the thrusters on Progress 67, which will put it at the proper altitude to meet up with Cygnus.
The crew also spent part of the workday photo documenting their uncommon “home life” aboard the orbiting laboratory for the Canadian Space Agency study called At Home in Space. This investigation assesses the culture, values and psychosocial adaptation of astronauts to a space environment shared by multinational crews during long mission timeframes. Questionnaires answered by the crew will help answer if astronauts develop a unique, shared space culture as an adaptive strategy for handling the cultural differences they encounter in their isolated and confined environment by creating a home in space.
For Flight Engineers Mark Vande Hei and Joe Acaba of NASA, their day was punctuated by an educational downlink with students from Shaker Heights High School in Cleveland, Ohio. The students were immersed in the science and technology studies being executed daily approximately 240 miles above Earth.
An experimental solar array demonstration was jettisoned while the Expedition 52 crew continued preparing the SpaceX Dragon for its release on Sunday. The three crew members also studied how microgravity impacts their bodies.
Following a week of successful science operations on the experiment for the Roll-Out Solar Array (ROSA), attempts to retract the array were unsuccessful. The ISS Mission Management Team met Monday morning and made the decision to jettison ROSA directly from its location at the end of the space station’s robotic arm, where it remained fully deployed in a normal configuration.
The original plan called for ROSA to be stored back inside the trunk of SpaceX’s Dragon which is detached and burned up in the atmosphere during Dragon reentry. The Operations team executed the jettison procedure that was developed as part of the pre-flight planning process that covered various scenarios. Once jettisoned, ROSA will not present any risk to the International Space Station and will not impact any upcoming visiting vehicle traffic.
ROSA is an experiment to test a new type of solar panel that rolls open in space and is more compact than current rigid panel designs. The ROSA investigation tests deployment and retraction, shape changes when the Earth blocks the sun, and other physical challenges to determine the array’s strength and durability.
The SpaceX Dragon cargo craft is one week away from departing the International Space Station. NASA astronaut Peggy Whitson continued packing Dragon this morning with used hardware and research samples for analysis back on Earth. Dragon will be released from the Canadarm2 Sunday at 11:38 a.m. EDT and splash down in the Pacific Ocean about 5-1/2 hours later.
Whitson then joined Flight Engineer Jack Fischer in the afternoon to wrap up the Seedling Growth-3 experiment. The botanical study is exploring how the lack of gravity impacts light sensing and growth in plants. Plant samples from the study will be returned to Earth on Sunday inside the Dragon resupply ship.
Commander Fyodor Yurchikhin, along with Whitson and Fischer, took body measurements today to help scientists understand how living in space affects body size. The crew also collected blood, urine, saliva and breath samples for more insight on astronaut health.

The crew researched the effects of living in space and set up a specialized microscope for a physics experiment today. Two astronauts are also getting ready for a Thursday spacewalk to continue setting up the International Space Station for commercial crew vehicles.
Flight Engineers Peggy Whitson and Thomas Pesquet used a tape measure this morning and measured their arms, legs, hips, waist and chest. Researchers are studying how microgravity impacts body size and shape and are comparing crew measurements before, during and after a space mission.
Whitson later began setting up gear for the ACE-T-1 (Advanced Colloids Experiment Temperature Control-1) physics study. She opened up the Fluids Integrated Rack and reconfigured the Light Microscopy Module to research tiny suspended particles designed by scientists and observe how they form organized structures within water.
Commander Shane Kimbrough is getting ready for another spacewalk on Thursday at 8 a.m. EDT. This time he’ll go outside with Whitson to finish cable connections at the Harmony module where the Pressurized Mating Adapter-3 (PMA-3) was robotically attached on Sunday. The PMA-3 relocation gets the adapter ready for the new International Docking Adapter-3 set to be delivered on a future cargo mission.
The Pressurized Mating Adapter-3 (PMA-3) was robotically removed Sunday from the Tranquility module and attached to the Harmony module after being prepared during a successful spacewalk Friday. A second spacewalk is scheduled for Thursday at 8 a.m. EDT to finalize the PMA-3 cable connections on Harmony.
Download hi-res video of briefing animations depicting the activities of all three spacewalks.
Commander Shane Kimbrough disconnected cables from PMA-3 while still attached to Tranquility during a spacewalk on Friday. That work allowed ground controllers to use the Canadarm2 robotic arm to remotely grapple and remove PMA-3 from Tranquility and attach it to Harmony.
The relocation readies the PMA-3 for the future installation of the new International Docking Adapter-3 (IDA-3) set to be delivered on a future cargo mission. The IDA-3 will accommodate commercial crew vehicle dockings and provide the pressurized interface between the station and the adapter.
Thursday’s spacewalk will see Kimbrough and Peggy Whitson complete the PMA-3 attachment work on the Harmony’s space-facing port. The duo will also install computer relay boxes containing software upgrades to enable future commercial crew vehicle dockings at the International Space Station.
