NASA has been well treated by both parties in general, with their budget rising faster than inflation most years. This administration also appointed Isaacman to be the NASA administrator which I think is a 10/10 choice for that job.
I’d argue that NASA should not have ever got into studying climate science, it should be a responsibility of NOAA. NASA should be focusing on NEP, atmospheric satellites, better aircraft, making life interplanetary and astronomy.
It’s not that simple. Trump admin requested a massive cut to NASA’s budget, which after much delay Congress finally rejected. Isaacman’s path to NASA administrator was also, erm, circuitous. Having a competent and knowledgeable NASA head was not really Trump admin’s priority.
