On Monday, January 29, 2018, two astronauts aboard the International Space Station (ISS) will perform the year’s second spacewalk to continue to work on the station’s robotic arm.
Live coverage of the spacewalk is scheduled to air on NASA TV, beginning at 10:30 UTC (5:30 a.m. EST; translate to your timezone). The spacewalk itself is scheduled to begin at about 12:10 UTC (7:10 a.m. EST).
Expedition 54 Flight Engineer Mark Vande Hei of NASA will lead the excursion, joined by Flight Engineer Norishige Kanai of the Japan Aerospace Exploration Agency (JAXA).
The year’s first spacewalk happened on January 23. The objective of that spacewalk, according to a NASA statement, was:
…to replace one of two redundant latching end effectors (LEE) on Canadarm2, the station’s robotic arm, which has experienced some degradation of its snaring cables. A spare LEE will replace the current LEE B.
Monday’s spacewalk will continue that work, and
… [secure] the degraded LEE B on the station’s Mobile Base System rail car as a spare. Similar work was conducted on the robotic arm’s LEE A during a series of spacewalks last October.
Bottom line: The second spacewalk of 2018 is scheduled for Monday, January 29, 2018. How to watch live.
