At least 10 major cities

The spacesuit worn by Neil Armstrong when he walked on the moon in 1969 is going back on display at the National Air and Space Museum in Washington, D.C., next week after a four-year, $700,000 preservation job. The suit is an airtight engineering marvel, made out of 21 layers of fabric, rubber, metal and fiberglass and designed to prevent punctures from micrometeorites. It was, however, only meant to last six months. [NPR]
With a party-line vote (shocking), the House Judiciary Committee voted to subpoena 12 witnesses — including Jared Kushner, Jeff Sessions, Rod Rosenstein, Michael Flynn, John Kelly, Rob Porter and American Media Inc. executives — as part of Democrats’ investigation into President Trump. “Enough already, go back to work!,” Trump tweeted.

A new artificial intelligence poker player called Pluribus, developed by a Facebook researchers and a Carnegie Mellon professor, has conquered six-player no-limit Texas hold ’em, outperforming a group of the world’s top human pros.

800,000 times normal
In 1989, a fire broke out on a Soviet nuclear submarine called the Komsomolets and it sank to the bottom of the Norwegian Sea. Today, according to the Norwegian Radiation and Nuclear Safety Authority, the sub is leaking radiation at 800,000 times normal levels. Researchers measured radiation at up to 800 becquerel per liter, which certainly sounds like a lot. The radiation poses little risk, apparently — there are few fish around and it’s easily diluted in the 5,000-foot depths of the sea. [The Washington Post]
