## SAC-C Summary and Mission Risk

***SAC-C Summary and Mission Risk***

***GSFC engineering is preparing a report to de-brief GSFC management on MMRS GENICOM relay micro-welding failure  ***
***Project recommendation is to use “as-is” due to one-time or limited use***
***In all cases, recovery is possible with use of redundant relays or redundant bus  ***
***Risk is considered Low***
***SAC-C READY FOR LAUNCH !***

## SAC-C Mission Readiness Status

*** ******. . . Paulino Garza***

## Slide 10

## NASA-Provided Services

***NASA-Provided Services***

***This new facility in Argentina required voice, Data and NASA select TV communications.***
***NASA provided a 64 kbps circuit for voice and data to Argentina and the needed end equipment for  voice terminals and router equipment.***
***NASA provided Ku band TV Receiving equipment.***

## CSOC-Provided Services

***CSOC-Provided Services***

***Successfully conducted Operational End-to-End Interface  testing between the MOC in Cordoba Argentina and Wallops, Norway, Alaska & McMurdo in April 2000.***
***Successfully conducted RF  Compatibility testing with the SIL transponder at Wallops and with the CTV in early 2000.***
***Training simulations are being planned to be conducted. Alaska will support the simulation in dual support mode. EO-1 on the 11 meter system and SAC-C on the 8 meter TOTS.***
***A joint SAC-C/EO-1, L&EO launch rehearsal for the first two orbits will also be conducted at about L-1 week.***

## Issues / Concerns

***Issues / Concerns***

***Late project requirements creep increases risk for readiness to support maneuvers.***
***A minimum impact for NASA select TV to Argentina is vulnerable to weather or other technical launch slips. About $10 k may be wasted. ***
***McMurdo unavailability as launch critical is a low probability but is a high risk to spacecraft safety.***

## Readiness Statement

***Readiness Statement***

***The SOMO/CSOC institutional services are ready for launch after completion of remaining simulations and resolution of the minor issues.***
