Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA completed the fourth spacewalk this year at 3:43 p.m. EDT, lasting 6 hours, 10 minutes. The two astronauts installed wireless communications antennas on the Tranquility module, replaced a camera system on the port truss and removed suspect hoses from a cooling system.
Spacewalkers have now spent a total of 54 days and 10 hours working outside the station in support of assembly and maintenance of the orbiting laboratory.
Watch the spacewalk live on NASA Television and the agency’s website.
Feustel is wearing the suit bearing the red stripes, and Arnold’s suit has no stripes. Views from a camera on Feustel’s helmet are designated with the number 17, and Arnold’s is labeled with the number 18. Feustel is designated extravehicular crew member 1 (EV1) for this spacewalk, the seventh of his career. Arnold, embarking on his third spacewalk, is extravehicular crew member 2 (EV2).
Once outside the airlock, Feustel’s first task will be to install the wireless communications antenna on the Tranquility module, while Arnold will begin the process of removing a set of hoses from the cooling system.
Once they have completed those activities, they will work together to replace a camera system on the port truss.
NASA Television has begun coverage of today’s spacewalk, as Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA prepare to work outside the International Space Station for approximately 6.5 hours. Today’s spacewalk was originally scheduled to begin at 8:10 a.m. However, suit leak checks took longer than anticipated and has put them approximately 60-90 minutes behind the original timeline.
The objective of today’s spacewalk will be to will install wireless communications antennas on the Tranquility module, replace a camera system on the port truss and remove suspect hoses from a cooling system.
The wireless communications equipment will enhance payload data processing for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) experiment being flown to the station on a future SpaceX Dragon cargo spacecraft. The experiment will measure the temperature of plants on Earth to better understand how much water they need and how they respond to stress.

The commercial cargo craft will be robotically captured and installed next Wednesday at 6 a.m. to the Earth-facing port of the Harmony module.
Kanai and Tingle will be at the robotics controls inside the cupola when they capture Dragon with the Canadarm2 robotic arm. The duo practiced the Dragon rendezvous and capture procedures today. The crew has also been configuring the orbital lab for the new science experiments Dragon is delivering next week.
One week from today three individuals will blast off on a two-day trip to the International Space Station. They will join the three Expedition 55 crew members already in space who continue to research the effects of living in space while maintaining the orbital laboratory.
The Soyuz spacecraft that will carry one cosmonaut and two astronauts to their new home in space was encapsulated into its rocket today ahead of its March 21 launch. Soyuz Commander Oleg Artemyev will fly the Soyuz MS-08 spacecraft ferrying him and NASA astronauts Ricky Arnold and Drew Feustel to the station’s Poisk module on March 23.
Waiting for the trio are Expedition 55 Commander Anton Shkaplerov and Flight Engineers Scott Tingle and Norishige Kanai. Today, the orbiting crewmates watered plants for a space crop study and scanned their eyes with an ultrasound device for ongoing health checks. They are also getting gear ready for the next spacewalk to conduct maintenance on the orbital lab.
The space station is orbiting a little higher today after a docked Russian cargo craft fired its engines for 1 minute and 48 seconds. The burn increased the lab’s altitude enabling future spacecraft operations including the undocking of the Expedition 54-55 trio in June and the docking of a new Russian space freighter in July.
Three members of the Expedition 54 crew aboard the International Space Station (ISS), including NASA astronauts Mark Vande Hei and Joe Acaba, have returned to Earth after months of performing research and spacewalks in low-Earth orbit.
Vande Hei, Acaba and cosmonaut Alexander Misurkin of the Russian space agency Roscosmos landed at 9:31 p.m. EST (8:31 a.m. Feb. 28 in Kazakhstan) southeast of the remote town of Dzhezkazgan in Kazakhstan.
Their time on station marked the beginning of the first long-term increase in crew size on the U.S. segment, enabling NASA to double the time dedicated to research and achieve a record-setting week of research that surpassed 100 hours. Highlights from this research include investigations into the manufacturing of fiber optic filaments in microgravity, improving the accuracy of an implantable glucoses biosensor, and measuring the Sun’s energy input to Earth.
The crew also welcomed four cargo spacecraft delivering several tons of supplies and research experiments. Orbital ATK’s Cygnus spacecraft arrived at the station in November on the company’s eighth commercial resupply mission, followed in December by SpaceX’s Dragon spacecraft on the company’s thirteenth resupply mission. Two Russian ISS Progress cargo craft arrived at the station in October and February.
Vande Hei logged 168 days in space on this, his first, mission. He ventured outside the space station on four spacewalks to perform work that included replacing and lubricating the Latching End Effectors on both ends of the Canadarm2. Acaba completed one spacewalk to lubricate an end effector and install new cameras on the station’s arm and truss. He now has accrued 306 days in space on three flights. Acaba and Vande Hei also participated in dozens of educational events while in space as part of NASA’s Year of Education on Station.
Misurkin conducted one record-setting spacewalk with fellow cosmonaut Anton Shkaplerov to replace an electronics box for a high-gain communications antenna on the Zvezda service module in February. The spacewalk timed out at 8 hours and 13 minutes, the longest in Russian space program history. Misurkin now has spent 334 days in space on two flights.
Now operating the station are Expedition 55 crew members Commander Anton Shkaplerov of Roscosmos and Flight Engineers Scott Tingle of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency. Astronauts Ricky Arnold and Drew Feustel of NASA, and Oleg Artemyev of Roscosmos are scheduled to launch March 21 and arrive at the space station two days later, returning the crew size to six.
Three Expedition 54 crew members are going into the weekend packing up and preparing to return to Earth on Tuesday. Commander Alexander Misurkin will lead fellow crew members Joe Acaba and Mark Vande Hei back to Earth inside the Soyuz MS-06 spacecraft Tuesday for a landing in south central Kazakhstan at 9:31 p.m. EST.
NASA TV will broadcast live all of the departure activities on Monday and Tuesday. The Change of Command Ceremony begins Monday at 2:40 p.m. when Misurkin hands over station control to cosmonaut Anton Shkaplerov. The new commander will stay behind with Flight Engineers Scott Tingle of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency and become Expedition 55 when their crewmates undock the next day.
The departing trio will say farewell Tuesday and close the Soyuz hatch at 2:15 p.m. They will undock from the Poisk module at 6:08 p.m. signifying the start of Expedition 55 and the end of Expedition 54. Next, the Soyuz engines will fire one last time at 8:38 p.m. sending the crew back into Earth’s atmosphere for a parachuted landing in Kazakhstan at 9:31 p.m.
The trio will have spent 168 days in space, orbiting Earth 2,688 times, conducted dozens of science experiments and seen the departure and arrival of eight different space ships. The departing crew members will also go home as experienced spacewalkers. Misurkin and Acaba each conducted one spacewalk and Vande Hei conducted four spacewalks during their five-and-half month stay in space.
