Bresnik and Vande Hei will venture back outside October 10 while Joe Acaba will join the station commander for the October 18 excursion.
Bresnik and Acaba will participate in three spacewalks this month to service the space station's robotic arm and install new external cameras.
They duo have been assigned to revolve around getting the Canadian robotic arm in good shape for doing work outside ISS.
The trio of spacewalks will be Bresnik's third, fourth and fifth, while Vande Hei will experience his first two spacewalks. The LEEs feature internal snares that rotate and tighten to lock onto grapple fixtures while latches engage to supply power, data and additional rigidity. In the early 2000s, Canadarm2 was used to help move and install large pieces of equipment. Joe Acaba arrived at the space station September 12 for his third mission to space.
For identification, Bresnik, call sign EV-1, is using helmet camera 18 and wearing a suit with red stripes. The first spacewalk will focus on repairing the orbiting lab's main robotic appendage, the Canadian robotic arm because its latching end effectors are not working properly. A spare LEE is located along the side of the station's truss.
"Since these components are well beyond their design life, this really is expected wear and tear on the arm", Braithwaite said. NASA astronaut Joe Acaba will join Bresnik for the third and final spacewalk.
They replaced one of two Latching End Effectors (LEE) which had lost the ability to grip effectively, said the United States space agency.
The next two spacewalks, on October 10 and October 18, will focus on lubricating the joints in the new LEE using a device called a ballscrew lubrication tool, or BLT.
