Story summary

The National Aeronautics and Space Administration (NASA) analyzes Orion system interactions to ensure mission design changes do not compromise functionality.
Both Human Landing System (HLS) providers face fuel challenges for reaching the lunar surface from a near-rectilinear halo orbit (NRHO).
They are exploring ways to reduce propellant needs as the 2028 landing approaches.
Testing an earlier lander version in Earth orbit aims to simplify requirements and build confidence.
