             | The goals it to fly often - adding a SLS launch to 2027 and
             | a second launch to 2028. This drops the cost-per-launch,
             | which is mostly fixed. It redoes SLS to make it less

             | station down to the surface of the moon.
             | 
             | And it's budgeted at $10B/3 years, which fits into NASA's

               | (https://www.nasa.gov/blogs/missions/2025/08/18/nasa-
               | begins-p...). It got moved to a 2028 manned lunar landing
               | in early 2026, before being converted back to a 2027
               | manned test flight.
               | 
               | The plan for SLS also does nothing to make it more
               | capable (though hopefully less expensive). The cancelled

               | which is a less powerful stage. Isaacman refuses (I think
               | rightfully) to really pin down on if there a future for
               | SLS past Artemis V. If Isaacman chooses to cancel SLS
               | after Artemis V (which I think is a defensible course of
               | action), then SLS would represent a ~17 year long program
               | that cost at least 41 billion dollars that netted 5
               | mission launches.

               | And characterizing it as "moving the lunar space station
               | down to the surface of the moon" is... kinda falling into
               | the trap. Lunar Gateway was supposed to launch ~2028
               | (along with Artemis IV - from the era where Artemis III
               | was the first lunar landing). Gateway was a gongshow, and
               | was delayed, and now cancelled. And now the new plan says
               | the habs (the part that people think as an actual
               | base...) happens in Phase 3 starting in 2033. The sort
               | term elements they are trying to reuse from gateway into
               | near term (think ~4 years) base projects are very
               | "ancillary".

               | It remains unclear if NASA will infact be able to up the
               | launch cadence of SLS to meet the double 2028 launch

               | limited sense for great expense, and the new plan is
