In space, no one can hear you scream, as the old saw goes. Does the same hold true for yelps of frustration at maintenance tasks gone awry? No doubt the crew aboard the International Space Station (ISS) has the answer after its recent spate of glitches and repair woes.
The third and final spacewalk of the Discovery shuttle mission to the ISS hit a snag yesterday, as a cargo carrier refused to swing out. The platform, one of two intended to store spare parts on future missions, was also the center of a snafu in the second spacewalk Saturday, when astronauts apparently installed a pin in the assembly upside down. ISS flight director Kwatsi Alibaruho told Reuters, however, that the pin was not to blame for the stuck platform. "We thought initially that the incorrect installation of the pin was the reason we were not able to rotate the (mechanism) down to its proper configuration," he said. "We now believe that (it is) just much, much stiffer than expected."
