As we have been reporting on Ars, NASA's Artemis II lunar mission has been going rather well so far. Of course, Orion's big test is yet to come with the fiery reentry through Earth's atmosphere on Friday. But so far, it's looking like the rocket and spaceship needed for a lunar landing are getting there for NASA.
The biggest remaining piece of the architecture, therefore, is a lunar lander. Known in NASA parlance as the Human Landing System, or HLS, the space agency has contracted with SpaceX for its Starship vehicle and Blue Origin and its Blue Moon lander.
Last year NASA asked both companies for options to accelerate their lunar landers, and both replied that not having to dock with the Lunar Gateway in a highly elliptical orbit, known as near-rectilinear halo orbit, would help a lot. So the space agency has removed that requirement.
