NASA astronauts will embark on a six-and-a-half-hour spacewalk Thursday, June 14, during which they will install new high-definition cameras to capture spacecraft docking with the International Space Station, including new American-made spacecraft with scheduled test flights later this year.

 

Live coverage of the planned spacewalk by American astronauts Drew Feustel and Ricky Arnold will begin at 6:30 a.m. EDT on NASA Television and the agency’s website.

 

Feustel, commander of the station’s Expedition 56, and flight engineer Arnold are scheduled to begin the spacewalk at 8:10 a.m.

 

The two spacewalkers will install brackets and high-definition cameras near an international docking adapter mated to the front end of the station’s Harmony module. The additions will provide enhanced views during the final phase of approach and docking of the SpaceX Crew Dragon and Boeing Starliner commercial crew spacecraft that will soon begin launching from American soil.

 

During their spacewalk, the astronauts also will swap out a camera assembly on the starboard truss of the station and close an aperture door on an external environmental imaging experiment outside the Japanese Kibo module. The imaging experiment hardware will be discarded on a future SpaceX cargo resupply mission.

 

The spacewalk will be the 211th in support of space station assembly and maintenance and the sixth station spacewalk this year. It also will be the ninth spacewalk in Feustel’s career and the fifth for Arnold. During the spacewalk, Arnold will wear a suit bearing red stripes while Feustel’s suit will have no stripes.

 

At five hours and 23 minutes into the spacewalk, Feustel will surpass NASA astronaut Peggy Whitson’s record of 60 hours and 21 minutes to move into third place for cumulative time spent during spacewalks.

Two NASA Astronauts Set to Go on Their Third Spacewalk This Year

NASA astronauts Ricky Arnold and Drew Feustel are suited up inside U.S. spacesuits for a fit check verification ahead of a spacewalk that took place May 16, 2016.

NASA astronauts Ricky Arnold and Drew Feustel are set to go on their third spacewalk together this year on Thursday at the International Space Station. Their new Expedition 56 crewmates Serena Auñón-Chancellor and Alexander Gerst are training today to support the two spacewalkers.

Arnold and Feustel will begin Thursday’s spacewalk at 8:10 a.m. to install new high definition cameras to support upcoming commercial crew missions from SpaceX and Boeing to the orbital laboratory. The first uncrewed test missions are planned to begin at the end of the year. The cameras will provide improved views of the commercial crew vehicles as they approach and dock to the station. NASA TV will provide complete live coverage of the 211th space station spacewalk starting at 6:30 a.m.

Auñón-Chancellor and Gerst, who just arrived at the station on Friday, will assist the spacewalkers on Thursday. Gerst will help the spacewalkers in and out of their spacesuits. Auñón-Chancellor will operate the Canadarm2 robotic arm. The duo practiced today on a computer the robotics procedures necessary to maneuver a spacewalker to and from the worksite on the starboard side of the station’s truss structure.

Arnold and Feustel had some extra time today to work on science and maintenance activities. Arnold worked with the Microgravity Science Glovebox to troubleshoot a semiconductor crystal growth experiment. Feustel performed some plumbing work in the Tranquility module before relocating a pair of incubator units to support new experiments being delivered on the next SpaceX Dragon cargo mission. Finally, the duo readied the Quest airlock and their spacesuits for Thursday morning’s spacewalk.

Spacewalking astronauts set up TV cameras for arriving ships

Spacewalking astronauts set up TV cameras Thursday for new crew capsules set to arrive in coming months.

The International Space Station's commander, Drew Feustel, and Ricky Arnold completed the job after struggling with a balky shield for protection against space debris. They accomplished everything, but a small item managed to slip away.

Feustel accidentally let go of a long, twisty wire tie as he secured one last piece of equipment, and it floated off into space.

"Now I have to live with the shame of losing a wire tie," he joked.

Wrapping up the ninth spacewalk of his career, Feustel moved into third place on the all-time spacewalking list, which is topped by a Russian. Altogether, Feustel has spent 61 hours and 48 minutes out in the vacuum of space.

As Thursday's spacewalk got underway, Feustel had to use a small crowbar to remove a protective shield in order to hook up a new cable for the high-definition TV cameras. Arnold floated over to help complete the initial cable work.

"Fantastic job," Mission Control radioed. But the NASA astronauts soon encountered more snags, slowing them down. They finally got the two high-def cameras installed on the end of 4 1/2-foot booms.

The cameras are meant to provide sharp views of commercial crew capsules coming in to dock.

Until SpaceX and Boeing start flying astronauts, NASA must rely solely on Russian capsules for getting to and from the 250-mile-high outpost. The Russians rides are costing NASA up to $82 million per person.

NASA hasn't launched astronauts into space from U.S. soil since the last shuttle flight in 2011. SpaceX and Boeing are aiming for test flights from Cape Canaveral, Florida, by year's end.

The tentative schedule shows flights without a crew by both companies in late summer followed by launches with astronauts by December. But those dates are considered optimistic.

During their nearly seven-hour spacewalk, Feustel and Arnold also replaced a camera in another part of the station, closed the flapping door to a laser-firing experiment to measure clouds and tackled some extra chores.

Once back inside, they both called out, "We're home!"
