Two NASA astronauts will repair the International Space Station’s huge robotic arm throughout a spacewalk on Tuesday (June 30), and you may watch the motion dwell.
Chris Williams and Jessica Meir will carry out a roughly 6.5-hour spacewalk exterior the International Space Station (ISS) at present, beginning at about 8:35 a.m. EDT (1235 GMT).
You can watch it dwell via NASA; Space.com will air the stream as effectively, if the company makes it accessible. Coverage will start at 7:00 a.m. EDT (1100 GMT).
Williams and Meir will change a 200-pound (90-kilogram) wrist joint, which malfunctioned “during normal Canadarm2 operations on May 27 after the arm drew elevated motor current and did not move as expected,” NASA officers wrote in a June 22 spacewalk preview.
The spare joint was already on board the ISS, which has been constantly occupied by rotating astronaut crews since November 2000.
“Repairs to robotics, like Canadarm2, are normal and expected after more than 25 years of continuous operations, as the system was designed with replaceable components and planned maintenance in mind,” NASA officers added within the preview.
Canadarm2 is sort of as outdated because the ISS. The 56-foot-long (17-meter-long), 3,300-pound (1,500-kg) robotic arrived on the orbiting lab aboard the house shuttle Endeavour in April 2001.
The upcoming extravehicular exercise (EVA) would be the second for Williams, who will probably be “spacewalk crewmember 1” and can put on a spacesuit with pink stripes. It would be the fifth for Meir, who will probably be “spacewalk crewmember 2” and can put on a swimsuit with no stripes.
The duo carried out an EVA collectively this previous March, spending seven hours prepping the orbiting lab for a brand new photo voltaic array.
Astronauts have carried out a complete of 279 spacewalks exterior the ISS thus far.
