It depends on how complicated it is. There are some less expensive ones that we can partner with other agencies that are on the order of a few hundred million dollars. Some of the more sophisticated satellites are more like $650,000,000. We built some in the past that have many instruments, sort of behemoths, that are over a billion. We're getting away from what we call flagship missions in Earth science. But a big, big part of that cost is launch vehicles -- just delivering the satellite into space. And that gets to be quite substantial and cuts into our ability to do the science we're trying to do.
