PROJECT SUMMARY: Application of NASA's Space Launch Initiative (SLI) Technologies to Future Heavy Lift Launch Vehicle (HLLV) Concepts

SEI investigated potential Heavy-Lift Launch Vehicle (HLLV) configurations predicated on technologies and flight elements that might result from NASA's Space Launch Initiative (SLI). The resultant HLLV configurations might then be employed to support NASA's Human Exploration and Development of Space (HEDS) missions currently being considered by NASA Code M. SEI specifically identified and documented synergistic technologies and flight elements between SLI and HLLV concepts. SEI developed a family of HLLVs known as Goliath of various payload capabilities utilizing either LOX/RP or LOX/LH2 Reusable Launch Vehicle (RLV) as boosters with a central LOX/LH2 core booster.
