The Space Launch System (SLS) Program kicked off its critical design review this week at NASA's Marshall Space Flight Center (nasa_marshall). Milestone reviews like the critical design review are just that -- critical. "CDR" demonstrates that the SLS design meets all system requirements with acceptable risk, and accomplishes that within cost and schedule constraints. It also proves that the rocket should continue with full-scale production, assembly, integration, and testing, and that the program is ready to begin the next major review covering design certification. Every milestone reached advances us on our #JourneyToMars.
