"The internal document, signed by NASA Associate Administrator William Gerstenmaier on Sept. 15, the day before the contract awards were announced, says, "I consider SNC's (Sierra Nevada Corp.) design to be the lowest level of maturity, with significantly more technical work and critical design decisions to accomplish. The proposal did not thoroughly address these design challenges and trades." Gerstenmaier goes on to say that Sierra's proposal "has more schedule uncertainty. For example, some of the testing planned after the crewed flight could be required before the crewed flight, and the impact of this movement will greatly stress the schedule."
