NASA just picked a new upper stage for its SLS moon rocket amid Artemis shakeup | Space

NASA made a big announcement about a change to the Artemis moon program, and after so many problems and delays, this was expected. 

There are several pieces to this announcement. The first is that they're going to away from the more intricate design that required several different types of rockets to be built, and they'll be focused on one type of rocket. 

Next, they're evolving the thinking on the lunar module. The design will be simplified and (if I understand it correctly), they'll be changing to a model more like the Apollo rockets lunar module, where they won't be landing the whole unit. 

And finally, the plan is to increase the frequency of launches to accelerate the program. 

Meanwhile, SpaceX and blue origin are also on the hunt to get to the moon and have some plans to build out solutions that may get us there sooner, too.
