CAPE CANAVERAL, Fla. -- NASA has patched an air-purifying system aboard the international space station.
A machine for removing carbon dioxide from the station atmosphere shut down Saturday. Flight controllers had it working again Sunday, but the temporary solution means extra people are needed in Mission Control, and lots of computer commands have to be sent up. Normally, the machine runs automatically.
NASA rushed to get it back up because of the record 13 people aboard the linked station and shuttle. Officials say even if the system had remained broken, Endeavour would not have had to undock early. But the system needs to work to support six station residents long term.
The astronauts will perform their fifth and final spacewalk Monday. Endeavour will undock Tuesday.
