ISS computer problems
STATION TEAMS SCRAMBLE TO RESOLVE COMPUTER GLITCH
-------------------------------------------------
A major computer failure in the Russian segment of the international space
station, possibly triggered by the addition of new U.S. solar arrays
earlier this week, has shut down critical systems and left the outpost
dependent on the shuttle Atlantis for any major changes in orientation.
The station cannot safely operate without the Russian computers and the
problem must be resolved before Atlantis departs next week.
