Lost in Space

Here's a good question about the space program: "When is NASA going to come down to Earth?" While I love the idea of space exploration, is it still necessary to send up shuttles so frequently, to spend so many billions of dollars, to risk lives so often, to take so many chances? Steve Dunleavy says, "Imagine the $110 billion going to research on heart disease, cancer or AIDS rather than looking around in space to confirm what you knew anyway - there is nothing there."
