I know they market mars hard, but the more relevant thing this is enabling is the starships that will be used for the NASA Artemis missions and upcoming moon base efforts. Those missions are going to need a few heavy flights each for the lander and a re-fueling ship, in addition to the SLS + Orion capsule for the actual astronauts.

Still wish the money was being invested in NASA to do themselves, and that it was being done without all the waste and environment destruction SpaceX so enjoys, but this is still a big deal to ensure Artemis happens.
