2、ay Satellite (TDRS) project entered into a firm fixed price contractual agreement to procure three spacecraft as part of the NASA replenishment program of the existing fleet. This contract contains performance penalties based upon any number of failed non-operational services after launch and checko

3、ut through years 1 to 8 on orbit. The contract also specifies that NASA is responsible for the provision of the launch vehicle, an Atlas IIA as “government furnished equipment.“ As a result, the government is responsible for providing the Atlas IIA under a separate contract and thus became responsib

4、le for the launch and delivery to orbit. The effect of this dual contract approach was to create a built in ambiguity reducing NASAs ability to make the TDRS contractor accountable for on orbit spacecraft performance and for NASA to enforce the performance penalties. The contract requires that NASA

5、is responsible for the safe delivery of the spacecraft on orbit and failure of the launch represents a total loss of mission to NASA.Lesson(s) Learned: Having a fixed price contract for a spacecraft delivery and a separate contract for the launch vehicle required the government be inserted as the re

6、sponsible party between the two contracts. The dual contract environment removed the governments ability to enforce the performance penalties in the event of a launch failure and created a complexity in the spacecraft to ELV interface requirements allocation and verification process. The complexity

7、was demonstrated by unwillingness to directly sign the launch vehicle interface control document (ICD), a joint agreement between NASA/KSC and NASA/GSFC. Instead, the TDRS Project Office at the Goddard Space Flight Center (GSFC) was forced to insert itself between the parties negotiating a launch ve
