A briefcase-sized tool bag drifted away from astronaut Heidemarie Stefanyshyn-Piper on Tuesday during the first of four scheduled space walks to repair a joint used to position a solar panel towards the sun. Stefanyshyn-Piper and Stephen Bowen where about half way through their first day when the bag somehow became untethered and floated away. The bag contained a pair of grease guns, wipes and a putty knife and NASA is now considering having the two astronauts share tools from Bowen's bag in order to complete the repairs. "What it boils down to is all it takes is one small mistake for a tether not to be hooked up quite correctly or to slip off, and that's what happened here,"according to lead spacewalk officer John Ray. At least there's a back up, what a costly mistake it could have been if the repairs could not be completed. Just goes to show that regardless of how much you train and practice we are human afterall and stuff happens. Discovery Channel Story.
