Washington, Feb 15: Two astrouts will venture outside the Intertiol Space Station (ISS) on Friday for a planned six-and-a-half hour spacewalk, SA has said.
Mark Vande Hei of SA and Norishige Kai of the Japan Aerospace Exploration Agency are scheduled to begin the spacewalk at 7.10 a.m. to move components for the station’s robotic system into long-term storage, the US space agency said on Wednesday.
The spacewalk will be the 208th in support of space station assembly and maintence and the third in 2018.
The two spacewalkers will move a Latching End Effector (LEE), or hand, for the Cadian-built robotic arm, Cadarm2, from a payload attachment on the station’s Mobile Base System rail car to the Quest airlock.
This LEE was replaced during an Expedition 53 spacewalk in October 2017, and will be returned to Earth to be refurbished and relaunched to the orbiting laboratory as a spare.
They also will move an aging, but functiol, LEE that was detached from the arm during a January 23 spacewalk and move it from its temporary storage outside the airlock to a long-term storage location.
That LEE will be available as a spare part on the Mobile Base System, which is used to move the arm and astrouts along the station’s truss structure. The spacewalk origilly was scheduled for January 29, but was postponed when a new LEE, installed during the spacewalk, encountered startup issues. (IANS)
