George Abbey: Time To Reconsider The Need For SLS

NASA's Space Launch System, George W.S. Abbey, Baker Institute for Public Policy

"In view of the current availability of a significant number of commercial launch vehicles with proven payload capabilities, as well as the industry's progress in providing a launch vehicle with significantly greater lift capabilities, the Biden administration should reconsider the need for the SLS during its annual budget review. Its launch costs are much greater than those being quoted for existing rockets, as well as those projected for larger commercial boosters with comparable payload capabilities to the SLS. Affordability must always be considered in view of demanding budgets and in view of the availability and the acceptability of lower-cost alternatives."
