GOES-15 , previously known as GOES-P , is an American weather satellite , which forms part of the Geostationary Operational Environmental Satellite (GOES) system operated by the U.S. National Oceanic and Atmospheric Administration . The spacecraft was constructed by Boeing , and is the last of three GOES satellites to be based on the BSS-601 bus. It was launched in 2010, while the other BSS-601 GOES satellites -- GOES-13 and GOES-14 —were launched in May 2006 and June 2009 respectively. [1] It was the sixteenth GOES satellite to be launched.
Launch
GOES-15 was launched atop a Delta IV-M+(4,2) rocket flying from Space Launch Complex 37B at the Cape Canaveral Air Force Station . [2] [3] The launch occurred at 23:57 UTC on 4 March 2010, forty minutes into a sixty-minute launch window . Upon reaching geostationary orbit on 16 March, it was redesignated GOES-15. [3] [4] On 6 December 2011, it was activated as the GOES-West satellite, replacing GOES-11 . [5]
Design
At launch, the mass of the satellite was 3,238 kilograms (7,139 lb) . It has a design life of ten years. Power is supplied by a single gallium arsenide solar panel , which provides up to 2.3 kilowatts of power. A 24 cell nickel hydrogen battery is used to provide power when the satellite is not in sunlight. [6] Instruments aboard GOES-15 include a five channel multispectral imager to capture visible light and infrared images of the continental United States , a sounder to take readings of atmospheric temperature and moisture, a solar x-ray imager to detect solar flares , and instruments to monitor the magnetosphere , cosmic background radiation and charged particles . [6]
Retirement
NOAA began to transition GOES-15 out of operational status at the GOES-West position in late 2018 to replace it with GOES-17 . [7] [8] GOES-15 began an eastward drift maneuver on 29 October 2018 to 128° W, with all of its sensors still functioning. [8] GOES-15's drift is intended to provide additional separation from GOES-17 to prevent communication interference. GOES-15 drifted east at a rate of 0.88° per day until 7 November 2018, when it reached its new operating location of 128° West. Once GOES-17 reached its assigned longitude on 13 November 2018, additional tests were performed; provided that testing goes well, GOES-17 will become operational as GOES-West on 10 December 2018. [8] Both GOES-17 and GOES-15 operated in tandem through early 2020 to allow for assessment of the performance of GOES-17 as the GOES-West operational satellite. [8] On March 2, 2020, GOES-15 was deactivated and moved to a storage orbit, with plans to re-activate it in August 2020 to back up GOES-17 operations due to a known flaw causing many sensors to become unreliable at night during certain times of the year.
