NASA Is Too Good At Science


NASA released a plan the other day to build a manned space station orbiting the moon. I’ve already seen a lot of talk about how bad a plan it is. And it is a pretty poor plan – but not for the reasons everyone says. A lunar orbiting base isn’t stupid in and of itself. It’s only a bad idea because of how NASA’s doing it. The critics say that this won’t produce enough science. They have it exactly backwards. This station produces too much science – like everything else NASA does.

Understand something important: NASA is really, really good at science. They do a lot of wonderful work. I have friends and family who do some of this work for NASA, and it’s brilliant. But NASA’s focus on science prevents the agency from focusing on what should be its primary mission: making access to space regular, easy, and cheap.

The biggest cost contributor, launch costs, will already fall dramatically over the next ten years. The private space race and companies like Space-X, Virgin Galactic, and Blue Origin, are already winning that battle. Space-X’s rocket system is already far cheaper than competitors, and as they make it more and more reusable it will become even cheaper.

But launch costs still won’t become “trivial.” As such, we’ll need to ensure that we’re using the mass we launch effectively. And the best way to do that – as I’ve noted before – is to build space infrastructure.

That is what NASA’s primary mission should be. Private industry will likely redo everything NASA does on the infrastructure front – and do it better and cheaper. Eventually. But planting the seed of that infrastructure would have huge payoffs.

One core piece of that infrastructure, as I’ve also discussed before, is that a system should be in place for earth-moon transit. And that system should largely consist of a ferry that travels only between two space stations – one in Earth orbit, and one in Lunar orbit. We already have a station in Earth orbit, so NASA’s new lunar orbit station could fulfill the role for the second part of that, right?

Possibly. But it would be a pretty crappy system if we built it that way, even by government standards. Both stations really need to serve two purposes, and only two purposes:

  • They need to be good transfer points to move people, cargo, or better yet, a space equivalent of standard shipping containers from one vehicle to another.
  • They need to be good supply depots, storing air, water, food, and most importantly fuel.

Basically, we need two giant truck stops in the sky.

The ISS is horrible at both of these tasks. It wasn’t built for it – because it was built to do science. And NASA’s new lunar orbit station looks poised to be built for science, also. As others have complained, there’s not enough science it could do to justify the cost.

But if we built it to support infrastructure, then the future science done – not by it, but by those who use it as a layover – could more than justify the cost.

Alas, NASA is too good at science to follow the better path.
