"When a Telescope Is a National-Security Risk"

Ross Andersen, writing at The Atlantic:

In the early months of 2023, the astronomer Željko Ivezić found himself taking part in a highly unusual negotiation. Ivezić is the 59-year-old director of the Vera Rubin Observatory, a $1 billion telescope that the United States has been developing in the Chilean high desert for more than 20 years. He was trying to reach an agreement that would keep his telescope from compromising America’s national security when it starts stargazing next year.

This task was odd enough for any scientist, and it was made more so by the fact that Ivezić had no idea with whom he was negotiating. “I didn’t even know which agency I was talking to,” he told me on a recent video call from his field office in Chile. Whoever it was would communicate with him only through intermediaries at the National Science Foundation. Ivezić didn’t even know whether one person or several people were on the other side of the exchange. All he knew was that they were very security-minded. Also, they seemed to know a great deal about astronomy.

Interesting story. $5M to build a secure network to redact and delay live results is a pretty wild outcome.
