• Nichelle Nichols touring Air & Space Tuesday morning. “Star Trek”’s first Uhura — in town for a NASA tribute — happened to pop in during an art preview featuring a canvas of the Starship Enterprise.

• Woody Harrelson trying to slip incognito into a screening of RFK Jr.’s “The Last Mountain” at E Street Cinema Monday, black ballcap pulled low. Lingered late at the Co Co. Sala afterparty, though, gabbing with Dennis Kucinich. He’s been in Baltimore lately, filming the Steve Schmidt role in “Game Change.”
