The brief
- SLS and Orion are NASA's crewed lunar vehicles; Artemis II flew four astronauts around the Moon in April 2026.
- X-59 QueSST flew supersonic in 2026, proving shaped airframes produce quiet thumps instead of sonic booms.
- NASA cancelled the Lunar Gateway orbital station to focus on a permanent lunar surface base.
Technical approach
Space Launch System
SLS combines Shuttle-derived RS-25 engines with five-segment solid boosters for 8.8 million pounds of thrust.
Orion
A conical crew capsule for four astronauts, reusable across multiple lunar missions, with a European service module supplying power and propulsion.
Shape-engineered airframe
The X-59's long, thin nose and precisely shaped fuselage break shock waves into separate pressure thumps perceived as quieter than traditional sonic booms.
