No.asa has quietly made public that the development of its giant rocket, the Space Launch System (SLS), is now budgeted for $ 9.1 billion (£ 7 billion). Ground systems to support the mission are estimated at an additional 2.4 billion dollars. As pointed out by Ars Technica, the new development cost represents a 33% increase in the cost of the mission.
During the test flight of November 2021, the Orion capsule will spend six days in lunar orbit. The central stage of the SLS rocket that will propel the flight is being tested at NASA’s Stennis Space Center near Bay St Louis, Mississippi.
