For the second time in six days, astronauts Suni Williams and Aki Hoshide stepped outside the $100 billion International Space Station to make some repairs Wednesday. This followed last Thursday's failed attempt to attach a power-switching unit on the outside of the station.
The problem: A stuck bolt.
So over the weekend the two spacewalkers came up with some tools, including a toothbrush attached to a metal pole, to help them clean out debris from the socket of the bolt, ABC News' Gina Sunseri reports.
After a nearly 7-hour spacewalk, the astronauts were able to drive in the bolt that fastens the switching unit to the station.
The unit harnesses electricity from the space station's eight solar wings and distributes power throughout the the orbiting outpost.
