It’s a lot less when you consider that it took 10 years to develop, build and launch that thing. That’s 10 years of wages for technicians, scientists, programmers and all the associated jobs - secretaries, cleaning staff etc.

And that’s the beauty of funding science: the money goes straight back into the economic cycle and also funds the training and education of the young scientists who are learning the ropes. This thing has funded probably dozens of PhD’s and hundreds of master students.
