Spacewalking astronauts gaveÂ theÂ International Space Station’s large drudge arm a new palm Thursday.
NASA Commander Randy Bresnik and Mark Vande HeiÂ floated out around 8 a.m. ET and stayed out for scarcely 7 hoursÂ to reinstate one of dual Latching EndÂ EffectorsÂ (LEE) on a Canadarm2.Â It’s a initial of 3 NASA spacewalks designed over a subsequent dual weeks.Â
The latching resource on one finish of a 17.7-metre Canadarm2 malfunctioned in August. It had to be transposed before a attainment of an OrbitalÂ ATK supply boat in November.Â
Hustling by their work, a spacewalkers unfastened a aged resource and soon commissioned a spare. Initial contrast by belligerent controllers indicated success.
“All right, gentlemen, we uncover a good arm,” Mission Control radioed.
“That is good news, Houston,” Bresnik said. “Much rejoicing.”
Canadarm2Â has dual identicalÂ LEEsÂ that areÂ used to squeeze visiting spacecraft, as good asÂ provide information and telemetry to a rest of a Canadian-built Mobile Base System.Â This gold of latches â€” some-more than a metre prolonged â€”Â also attaches to fastener fixtures outward a space station. That way, a arm can pierce likeÂ an inchworm conflicting a sprawling structure.Â
The Canadian-built arm has been in circuit for 16 years. The dual latchingÂ mechanisms, one on any finish of a arm, have been used scarcely 400Â times, and engineersÂ attribute a new difficulty to wear and tear.Â
The latching resource on a conflicting finish will be transposed earlyÂ next year.
It was a initial spacewalk for Vande Hei, a rookie wanderer whoÂ arrived during a orbiting outpost a few weeks ago.Â
“Congratulations, my friend, on apropos a 221st tellurian to exitÂ in your possess personal booster into a blank of space,” saidÂ Bresnik, a maestro spacewalker.Â
As a twin worked, they marvelled over a views of Earth belowÂ and a full moon above.Â They’ll try behind out on Tuesday toÂ lubricate a new resource and do other chores.
