- Program Status
- Launch Planning
- GOES-R Series

## GOES MISSION

- GOES satisfies National Weather Service (NWS) requirements for 24 hour observation of weather and Earth’s environment to support storm-scale weather forecasting by forecasters and numerical models
- To meet requirements, GOES continuously maintains operational satellites at two locations (75 degrees West and 135 degrees West), with and on-orbit spare ready in case of failure

-    Data are provided to users routinely from the Imager every 15 minutes and
-      from the Sounder every hour throughout the day from each satellite.  More rapid
-      repetition is used when needed for severe weather events.

## GOES On-Orbit Status

- GOES-8 continues to function as the GOES-East operational satellite
- Functioning on several redundant systems
- Depletes all fuel reserves by April 2003
- Has exceeded operational life by 3 + years
- GOES-9 removed from operational service in July 1998
- Being made available to the Japanese to provide emergency coverage, if necessary
- GOES-10 has functioned as the GOES-West operational satellite for the last 41/2 years
- Difficult to quantify remaining mission life due to Solar Array anomaly
- GOES -11 and GOES –12 are in on-orbit storage mode, ready to replace either GOES-East or West
- Transition plan being developed to move GOES-12 to GOES-East

## GOES-N Series Development/Production Status 

- GOES-N Series Spacecraft (Boeing Satellite Systems (BSS), Inc.)
- Government provided instruments delivered to Spacecraft contractor and successfully integrated on GOES-N Spacecraft
- GOES-N Spacecraft system level testing underway
- GOES-N Series Spacecraft Support Ground System (SSGS) delivered to NOAA’s SOCC
- Successfully completed two command/TLM/Data End-to-End testing between Spacecraft and NOAA’s SOCC
- GOES-N Spacecraft on schedule to support January 2004 launch readiness
- The GOES-O Bus and Payload Modules Completed

## GOES-N Series Instruments Status

- GOES-N Series Instruments Status

- GOES-N Series Imagers and Sounders (ITT)
- The GOES-N (S/N08) Imager and Sounder mechanically/electrically integrated onto the GOES-N bus
- The GOES-O (S/N09) Imager and Sounder mechanically integrated on to the GOES-O bus
- GOES-P (S/N10) Imager and Sounder are in temporary storage at ITT.
- Preliminary integration of S/N 11 Imager and Sounder started, leading to the ship dates of June 14, 2003 for the Imager and July 31, 2003 for the Sounder.

**Notes:**
May mean  retesting at higher vibration loads 

## GOES-N Spacecraft Instrument Testing

- Spacecraft in the Z over west panel down configuration
- Sounder radiant cooler door open in preparation for ITT to perform the door hinge friction test
- Picture taken 3/26/02

## GOES-N Series Instruments Status (Continued)

- GOES-N Series Instruments Status (Continued)

- NOAA GOES-N Series FM1 and FM2 Solar X-Ray Imagers (SXI)
- The FM1 SXI delivered to BSS November 2001
- Successfully integrated on GOES-N
- The FM2 SXI delivered to BSS September 2002
- Successfully integrated on GOES-O for ground testing, but may not fly on GOES-O
- GOES-N Series Space Environment Monitor (SEM)
- GOES-N SEM - Successfully delivered and integrated on GOES-N
- Delivery of the GOES-O SEM - December 2002

- (Lockheed Martin)

**Notes:**
To avoid Optical Solar Reflector (OSR)
