Re: As much as I hate him...
"Bill Nelson was the only decent NASA Admin since the '60s."
Senator Ballast? No.
Charlie Bolden was much better and more qualified for the job.
One of the noticeable things that's been happening is NASA being whipsawed by political projects rather than being given the goal of doing good science and suggesting valuable projects as well as being the consulting agency for outside suggestions of projects in aeronautics/space.
I was recently watching a show about some scientists collecting data on the number and density of trees on the planet. Some of the technology they were using was from NASA and both space sensing and spun off tech for scanning environments on the ground. I had the opportunity to work on some projects with Dr Chris McKay who was looking for life on Mars, on Earth. He was using the technology that we have already in Earth orbit to look at the sorts of extreme environments that exist on Mars and visiting those place to look closely at what was on the ground. One location I was able to go to with him was a hill in southern California dubbed "Little Red Hill" now contained inside Ft Irwin. The rocks are coated with iron oxide and the landscape is pretty bleak. Under the quartz rocks, there can be algae growing. There's just enough light getting through and the space under the rock is protected just enough. The trick is to see if there is a hint it's there via remote sensing since astronauts wandering around on Mars turning over random rocks would be a poor use of their time unless there was good evidence they'd hit pay dirt (regolith) in short order.
Besides all of the off-world things, remote sensing from space for earthly information is a "killer-app" for NASA. It's hard, expensive and might take many years to bear fruit. If it means more efficient management of food production or a way to make better predictions of tornadoes, those are things with so much payback that it's hard to put a price on.
