NASA And NOAA Investigation Into GOES-17 Satellite Failures Accomplished
The primary device on GOES-17 satellite of NOAA, the Advanced Baseline Imager (ABI), had experienced an impasse in the loop heat pipe. This thwarted the device from cooling appropriately and obstructed its capability to gather information, as per a special Mishap Investigation Board. Following the liftoff on March 1, 2018, of GOES-17, during the device check-out phase, engineers found the infrared detectors of ABI couldn’t keep up the needed temperatures in specific orbital conditions.
The panel appointed by NASA and NOAA concluded that flow of the coolant within the pipes was limited by the blockage, resulting in overheating of the ABI electronics, sinking its infrared sensors’ sensitivity. Engineers were able to mitigate the issue through operational changes to the instrument and mission operations, including the use of Artificial Intelligence techniques, to restore most of the ABI’s functionality. Now, the GOES-17 ABI is anticipated to deliver over 97% of the data it was intended to transmit.
At present, GOES-17 is offering rapid, more precise, and more comprehensive observations utilized by forecasters of NOAA National Weather Service to envisage Pacific storm systems, wildfires, fog, severe storms, and other environmental hazards. Additionally, tropical cyclones are also monitored by GOES-17 in the Pacific Ocean.
Likewise, on August 8, the 5th Advanced Extremely High-Frequency satellite was lifted-off into orbit successfully. The Air Force satellite was blasted-off from Cape Canaveral, FL, at 6:13 a.m. atop a United Launch Alliance Atlas V rocket. The satellite, after its 6-hour voyage, reached the geosynchronous orbit beside the 4 other AEHF satellites already functioning in orbit.
This latest satellite was the 5th of 6 anti-jamming satellites within the AEHF constellation. The satellites, developed by Lockheed Martin, are utilized for highly defended communications by top-priority national leaders and military assets. Only one AEHF satellite offers 3x more capacity compared to the complete legacy system, Milstar constellation, it is substituting.
