We’re all basking in the success of the James Webb Space Telescope. It’s fulfilling its promise as our most powerful telescope, making all kinds of discoveries that we’ve been anticipating and hoping for. But the JWST’s story is one of broken budgets, repeated requests for more time and money, and near-cancellations.

Can we make space telescopes less expensive?

After a quarter-century of development, NASA’s James Webb Space Telescope is a smashing success. But senior project scientist John Mather, a Nobel-winning physicist who’s played a key role in the $10 billion project since the beginning, still sees some room for improvement.

Mather looked back at what went right during JWST’s creation, as well as what could be done better the next time around, during a lecture delivered today at the American Astronomical Society’s winter meeting in Seattle.
