NOAA does not build or launch or maintain satellites. They don't. NASA does. That's what they do. NOAA does not have flight ops. NOAA does not have a launchpad. NOAA does not have giant clean room facilities for building satellites. NOAA provides the requirements, NASA builds/launches/maintains the satellites.
And they don't need to. I use a computer with complicated software every day for work. But I don't know how to build that complicated software, or the computer, or the chair I sit on.
There are a lot of companies out there, and a few countries too, that will happily design and put satellites in space for a fee. One of the big problems with government funded research (and I say this as someone who does not have a philosophical opposition to governments funding research) is that sooner or later, government departments see the big pile of money that is available for climate change programs, and want a piece of the action. NASA - because we know space, and can watch the climate from space. The army, because defending the country requires understanding the weather . climate - hence we want some of that action. EPA - because we protect the environment, and therefore we need to get in on the climate science action and therefore want that funding.
Why can't there be one organisation whose job it is to study the earth and climate, and let all other organisations do what they are meant to do, like look out into space, and find ways of protecting the environment without all needing to justifying everything on climate.
