Topic: McMurdo/RIES UPS Replacement Maintenance Scheduled for January 22, 2025
Date/Time Issued: January 17, 2025 1501Z
Product(s) or Data Impacted: All NOAA-20 and NOAA-21 SMD Data
Date/Time of Initial Impact: January 22, 2025 1845Z
Date/Time of Expected End: January 22, 2025 2300Z
Length of Outage: 4 Hours, 15 Minutes
Details/Specifics of change: The McMurdo Ross Island Earth Station (RIES) Ground Station will be undergoing maintenance on January 22, 2025 (DOY022) from 18:45 UTC – 23:00 UTC. During this period of maintenance, the primary Southern Hemisphere downlink will be unavailable, and downlinks will occur on nominal sequential Northern Hemisphere Svalbard or Fairbanks passes.
As this work is occurring on the ice in McMurdo, schedule may shift unexpectedly within the overall maintenance period, and systems and engineering will work with operations to provide situational awareness.
The following observatory systems will be affected on January 22, 2025:
The JPSS contacts identified below will be taking a ½ orbit mission data latency hit for the contacts within the maintenance window and will be at the subsequent Northern Hemisphere contact for the impacted passes:
NOAA-21:
- Rev 11414 (Jan 22 20:16 – 20:28 UTC
- Rev 11415 (Jan 22 21:59 – 22:11 UTC
