Spacewalkers Going Outside Second Time in Less Than a Week

Spacewalkers Mark Vande Hei and Randy Bresnik

Spacewalkers Mark Vande Hei and Randy Bresnik are pictured Oct. 5, 2017, working outside the International Space Station.

Expedition 53 Commander Randy Bresnik and Flight Engineer Mark Vande Hei of NASA will head outside the International Space Station at approximately 8 a.m. EDT Tuesday to begin a 6.5-hour spacewalk. Live coverage will be available on NASA Television and the agency’s website beginning at 6:30 a.m.

During Tuesday’s spacewalk, Bresnik and Vande Hei will lubricate the Canadarm2 Latching End Effectors (LEE) that the spacewalkers replaced Oct. 5. Canadarm2 has two identical Latching End Effectors used to grapple visiting cargo vehicles and payloads, provide data and telemetry to the rest of the Canadian-built Mobile Base System and the unique capability to “walk” from one location on the station’s truss to another. The Canadarm2 grappling mechanism that was replaced last week experienced a stall of its motorized latches last month.

This will be the 204th spacewalk in support of space station assembly and maintenance, and the second of three spacewalks planned for October.
