> HOUSTON - NASA has added a new computer program to help monitor the 
> four gyroscopes that keep the International Space Station properly 
> oriented without the use of rocket fuel. During a spacewalk on 
> Monday, two astronauts from the space shuttle Endeavour removed and 
> replaced a gyroscope that failed in late 2006.
> Computer scientists at NASA's Ames Research Center, Moffett Field, 
> Calif., designed the new software for the space station. The 
> Inductive Monitoring System will be added to a group of existing 
> tools to identify and track problems related to the gyroscopes. 
> "If the system does something unexpected, the software alerts ground 
> controllers that something is different, an anomaly, and that allows 
> them to analyze the situation and take preventive measures as 
> necessary," said David Iverson, the computer scientist at Ames who 
> spearheaded the five year-effort to develop the software.
> During its development, researchers used the software to analyze 
> several months of normal space station gyroscope data collected by 
> the International Space Station Mission Control Center at NASA's 
> Johnson Space Center, Houston. In these tests, problems with the 
> gyroscopes were noticed long before the previous system flagged 
> glitches. NASA started using the software earlier this year. 
> The software program also has been used in F-18 fighter planes and by 
> the space shuttle's leading edge impact detection system, as well as 
> for electric power plant and water quality monitoring.
