Expedition 53 Spacewalk Successfully Comes to an End

Posted on by .

Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA completed a 6 hour, 49 minute spacewalk at 2:36 p.m. EDT. The two astronauts installed a new camera system on the Canadarm2 robotic arm’s latching end effector, an HD camera on the starboard truss of the station and replaced a fuse on the Dextre robotic arm extension.
 
The duo worked quickly and were able to complete several “get ahead” tasks. Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar. Bresnik completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future. He nearly finished prep work on the second, but that work will be completed by future spacewalkers.
 
This was the fifth spacewalk of Bresnik’s career (32 hours total spacewalking) and the third for Acaba (19 hours and 46 minutes total spacewalking). Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, 6 hours and 25 minutes working outside the station.

Expedition 53 Embarks upon Third and Final Spacewalk in October Series

Posted on by .

Two NASA astronauts switched their spacesuits to battery power this morning at 7:47 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last about 6.5 hours. Live coverage is available on NASA Television and the agency’s website.

Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA will replace a camera light assembly on the Canadarm2 latching end effectors (LEE) that spacewalkers installed on the Canadarm2 robotic Oct. 5. They will also install an HD camera outside the station among other tasks in the 205th spacewalk in support of assembly and maintenance in station history.

Bresnik is wearing the suit with red stripes, and helmet camera #18. Acaba is wearing the suit with no stripes, and helmet camera #17.

Spacewalk Comes to a Close

The two spacewalkers exited the Pirs Docking Compartment Station at 10:36 a.m. EDT. Among their accomplishments was manual deployment of five nanosatellites from a ladder outside the airlock.

One of the satellites, with casings made using 3-D printing technology, will test the effect of the low-Earth-orbit environment on the composition of 3-D printed materials. Another satellite contains recorded greetings to the people of Earth in 11 languages. A third satellite commemorates the 60th anniversary of the launch and the 160th anniversary of the birth of Russian scientist.

They also collected residue samples from various locations outside the Russian segment of the station.
