The International Space Station (ISS) is back on track for normal operation, with the computers responsible for maintaining crucial systems coming back on line slowly. 

On Saturday, Russian cosmonauts began turning on some of the crucial systems that had been shut down more than four days ago when computers crashed.
First to come online was a machine that scrubs carbon dioxide from the air inside the ISS.
It took four days to restore the computer systems, but cosmonauts eventually manged to get four of the six affected processors working by bypassing a circuit board. The other two processors will need to be replaced.
The computers on the Russian side of the ISS are responsible for providing oxygen and maintaining the ISS's position in orbit.
