Summary of Phase I Developed an investment porTolio that strikes a balance of new developments, technology, and operaQonal programs with an eye towards a new way of exploring. Created a point of departure DRM that is flexible and can evolve over Qme to support mulQple desQnaQons with the idenQfied systems. IdenQfied a minimum subset of elements needed to conduct earlier beyond LEO missions. Infused key technology developments that should begin in earnest and idenQfied gaps which should help inform addiQonal technology prioriQzaQon over and above the NEO focused DRM. Costed the DRM using tradiQonal cosQng methodologies. Determined alternaQve development opQons are required to address the cost and schedule shorTalls.

DRM IntroducQon Previous HEFT DRM analyses helped draw conclusions regarding system requirements for the NEO missions examined • In‐space propulsion technology advances and high system reusability did not obviate need for higher capacity launcher (excessive number of commercial launches, DRM Set 1) • Commercial on‐orbit refueling did not obviate need for higher capacity launcher (excessive number of commercial launches, DRM Set 2). Commercial launch rate available for explora#on missions significantly limited by costs of infrastructure expansion. “Hybrid” DRM analysis (“DRM 4”) presented to Steering Council 17 August. AddiQonal analysis performed to assess: • “Balanced” HLLV/Commercial launchers • Impacts of “moderate” HLLV capacity • Impacts of dele#on of solar electric propulsion (SEP) technology/system • Qualita#ve assessment of SEP NASAWATCH.COM Pre‐Decisional: For NASA Internal Use Only 5
