Earlier this year, @Space_Station's Canadarm robotic arm underwent some repairs. More recently, the mobile platform it sits on suffered communications problems. Upcoming Spacewalks 100 and 101 are reliant on these, so I asked @NASA if they were monitoring any concerns: Canadarm2 is operating nominally, and the agency is not tracking any issues, according to Gaurang Patel, Operations Integration Manager, Low Earth Orbit Program. The moving platform, known as the Mobile Transporter, had some transaction errors on communications Channel A. Because of this, Channel B has been made the prime communications channel for these upcoming EVAs. The team continues to conduct checkouts on Channel A, and when redundancy is required, it continues to show an ability that it can be utilized. 📷 @NASA
