- The US government getting out of the business of designing launchers: We'd acquire launchers the same way the Air Force gets airplanes: define requirements and solicit bids. This isn't perfect (see: F-35), but it's a darn sight better than the current SLS process. After all, in World War 2, it's not as if the US Army Air Corps (and later, the US Army Air Force) designed every plane that it acquired. It put out requirements and solicited designs from aircraft manufacturers like Boeing, Curtiss, Vought, Douglas, etc. Now that rocketry is no longer an unproven and speculative endeavor, we should do the same, and seek to build up multiple competing rocket manufacturers
- Giving near-Earth science to NOAA: Right now, Earth-focused satellites are split between NASA and NOAA. Giving a single agency responsibility for Earth-focused scientific satellites will ensure that they have a single clear voice advocating on their behalf
- Sending the astronaut program back to the Air Force (or maybe create the much ballyhooed "Space Force")
- Creating a new, smaller, more focused organization for exploration of deep space (i.e. space beyond Earth's gravity well). While this organization could wear NASA's logos, I think it would be better if there were a clean break with the past and the organization got a new name and new branding
