Topic: DSCOVR Processor Reset
Date/Time Issued: July 15, 2025 1910Z
Product(s) or Data Impacted: DSCOVR Instruments
Date/Time of Initial Impact: July 15, 2025 1742Z
Date/Time of Expected End: TBD
Length of Outage: Instrument outage varies, see detail outage below
Details/Specifics of Change: Due to a software bus anomaly, DSCOVR must perform a processor reset to return to nominal operations. This activity will result in a data outage for all instruments as the engineering team initiates a processor reset, recovers the spacecraft from safehold mode, and configures the spacecraft and instruments for science mode. Due to antenna constraints at WCDAS and DSN, outage times will vary from previous resets and will be provided as the recovery commences. The primary customer, NOAA/NWS Space Weather Prediction Center (SWPC), will switch over to ACE as primary source during the DSCOVR Commanded Reset activities.
