A veteran NASA spacewalker and an EVA rookie from Japan ended their week with nearly six hours of work outside the International Space Station on Friday to finish the restoration of the Station’s Mobile Servicing System that started last year and continued in January to provide Canadarm2 with a new pair of grappling hands.
Two Russian Cosmonauts had a trial of patience on Friday when working on the Service Module of the International Space Station to replace antiquated communications gear with new electronics to enable the Russian ISS Segment to connect to Russia’s Luch satellites positioned in Geostationary Orbit as high-altitude relay points.
International Space Station managers decided on Sunday to postpone a scheduled spacewalk from Monday after additional diagnostics performed on the Station’s Canadarm2 robotic arm showed a connectivity problem on the primary command string of the newly-installed Latching End Effector could be solved through software.
Spacewalkers aboard the International Space Station will be forced to backtrack on Monday, reversing work completed on a January 23 excursion after controllers on the ground were unable to establish a redundant command path to the newly-installed grappling hand on the Station’s Canadarm2 robotic arm.
Europe’s Ariane 5 appears to have gotten away with a black eye on Thursday when its 97th mission veered off course from the onset of the rocket’s climb, but still managed to deploy two innovative communications craft in a stable, but off-target orbit from where it will be up to the SES 14 and Al Yah 3 satellites to rectify the situation and maneuver into their operational slots above the equator.
Europe’s Ariane 5 launch vehicle, after 82 consecutive successes over a 15-year streak, encountered a potentially serious anomaly on Thursday when lifting a pair of cutting-edge communications satellites into a high-energy Supersynchronous Transfer Orbit.
