If unable to execute the primary burn at 16:12Z, a contingency back burn is also scheduled at 22:58Z. Due to the DMU activities, some of the ATMS Scan Reversals will not occur. During the period of DMU preparation and activities, ATMS Scan Reversals will be manually commanded to minimize skipped reversals, but may not occur exactly at stepped latitudes and thus small data gaps may be introduced. The following observatory systems will be affected on September 13, 2016 (for primary burn times): *12:00:00Z – 23:30:00Z * ATMS Scan Reversal will be manually commanded, some reversals will be missed. *15:46:00Z – 17:53:04Z* CERES in Contam-Safe mode, science data will not be available *15:56:00Z – 16:23:06Z* OMPS in Decon mode, Science data will not be available *16:01:00Z - 16:24:04Z* HRD will be off, data for direct broadcast users will be unavailable *16:06:00Z – 16:19:04Z* S-NPP pointing off-nadir, collected data during that time period may be impacted and not disseminated Contact Information for Further Information: ESPC Operations at ESPCOperations@noaa.gov at 301-817-3880 Web Site(s) for applicable information: N/A This message was sent to ESPC.Notification@noaa.gov .

Topic:  S-NPP Drag Make-UP (DMU) Maneuver scheduled for September 13, 2016

Date/Time Issued:  September 12, 2016 20:20Z

Product(s) or Data Impacted:  All S-NPP Sensor Data

Date/Time of Initial Impact: September 13, 2016  12:00Z

Date/Time of Expected End: September 13, 2016  23:30Z

Length of Outage:  See Details.

Details/Specifics of Change: On September 13, 2016 at 16:12Z, S-NPP will perform a 2 second propulsive Drag Make-UP (DMU) maneuver to maintain Repeating Ground Track.  If unable to execute the primary  burn at 16:12Z, a contingency back burn is also scheduled at 22:58Z. Due to the DMU activities, some of the ATMS Scan Reversals will not occur.  During the period of DMU preparation and activities, ATMS Scan Reversals will be manually commanded to minimize skipped reversals, but may not occur exactly at stepped latitudes and thus small data gaps may be introduced.

The following observatory systems will be affected on September 13, 2016 (for primary burn times):

12:00:00Z – 23:30:00Z  ATMS Scan Reversal will be manually commanded, some reversals will be missed.

15:46:00Z – 17:53:04Z  CERES in Contam-Safe mode, science data will not be available

15:56:00Z – 16:23:06Z  OMPS in Decon mode, Science data will not be available

16:01:00Z - 16:24:04Z  HRD will be off, data for direct broadcast users will be unavailable

16:06:00Z – 16:19:04Z  S-NPP pointing off-nadir, collected data during that time period may be impacted and not disseminated
