Imagine a telescope spots oxygen and methane in an alien world's air. That's a discovery crewed spaceflight can't match at any price. My opponent will say humans inspire and explore. Fair. But ask a simple yes or no: which investment buys more scientific return per dollar, a crewed Mars mission or a space telescope? The telescope, every time. Crewed flight is thrilling, but thrills aren't a metric. If we're investing, telescopes win on cost, scope, and evidence. That's my case.
