Services
from one of the INSAT satellites, INSAT-4A, were disrupted for
about half an hour around 4 pm this afternoon (January 2, 2007)
due to solar disturbances. INSAT-4A lost earth lock when one of
the momentum wheels used for stabilizing the spacecraft got switched
off. ISRO engineers at Master Control Facility, Hassan, immediately
took action to recover the earth lock and orient the satellite
properly within about half an hour.
