NOAA's GOES-13 returns to full operations, GOES-14 to remain orbital spare

The GOES-13 spacecraft, which had its sounder and imager instruments taken out of service because of technical trouble in late September, will return to full operations on Thursday, Oct. 18, 2012 as NOAA's GOES East satellite, NOAA officials said.

The trouble stemmed from a motor vibration, which caused a lubricant buildup that obstructed the spinning motion of the filter wheel in the sounder. A team of engineers from NOAA, Boeing and ITT suppressed the vibration, the filter wheel restarted and is running smoothly, with improved performance.

NOAA turned off the two instruments on September 23, and immediately configured GOES-15, the West Coast satellite, to provide additional coverage of the eastern United States and part of the Atlantic Ocean. Within a few hours, NOAA activated its on-orbit spare satellite, GOES-14, for full service.

And as a team of engineers from NOAA, Boeing and ITT continued to pinpoint the cause of the problem, NOAA began moving GOES-14 towards the position where GOES-13 was situated. GOES-14 will return to its earlier status as the on-orbit spare, NOAA officials said.

GOES-13 had been NOAA's , providing coverage of the U.S. East Coast, since April 14, 2010. At all times, NOAA operates two GOES spacecraft 22,300 miles above the , with an additional GOES in orbital storage mode, ready to step in if one of the active satellites experiences trouble.

NOAA manages the GOES program, establishes requirements, provides all funding and distributes environmental for the United States. The GOES Program at NASA's Goddard Space Flight Center in Greenbelt, Md., procures and manages the design, development and of the satellites for NOAA on a cost reimbursable basis.
