   How Can We Bring Down the Costs of Large Space Telescopes?

   JWST is the most powerful telescope ever built by humanity, but it cost around $10 billion. Astronomers are already planning next-generation telescopes that should be even bigger and more sensitive, but the costs can't keep rising. A new paper suggests new approaches that could lower the costs of large space telescopes, using bigger launch vehicles, advanced computing, and low-cost control systems. There's no single silver bullet, but these new techniques could get us more giant telescopes without accelerating budgets.
