The Lunar Gateway allows NASA to break up missions to the Moon into two steps, with reusable hardware and long-term infrastructure. You fly to and from the Gateway with a reusable capsule like Orion (or maybe a deep-space version of Crew Dragon).

Then a reusable lunar lander ferries to and from Gateway to the lunar surface, eventually to a lunar base.

One of the modes of its MIRI instrument was experiencing excess friction so NASA took it offline. They've figured out a workaround and brought it back online.
