ERBS Spacecraft Emergency

NASA's Earth Radiation Budget Satellite (ERBS) declared a "spacecraft
emergency" on Friday, January 15th at 8:07 a.m. EST (1307Z) due to an
unstable power condition. Ground controllers terminated the emergency
around 2:55 p.m. EST (1955Z), however the spacecraft remained in a critical
state. 

A second spacecraft emergency was declared on Saturday, January 16th at
8:40 a.m. EST (1340Z) when the satellite went into a "controlled tumble
condition". The emergency was later terminated at 4:30 p.m. EST (2130Z)
after the spacecraft's attitude became stabilized, however the system
remains in a critical state.
