摘要

International Space Station engineers are assessing the potential long-term implications of fleeting abnormal behavior noted on one of the station's three remaining control moment gyros (CMGs) important to maneuvering the 330,000-lb. station complex. ISS controllers at the Johnson Space Center have implemented gyro protection measures through at least mid-January until they can better understand what may have occurred with CMG-3 in November. One of the station's other original four attitude gyros, CMG-1, failed catastrophically in 2002 only 16% through its planned 8.5-year life. This has given rise to some concern that CMG-3 could also be headed toward a premature failure - although so far that is not the case.
