The powers of Rosario Dawson’s megawatt smile are well known, but last night she literally lit up a room. She was on hand to help artist Luke Jerram illuminate a massive, 23-foot-tall globe displaying NASA surface imagery of the moon. Previously on display across Europe and in Hong Kong, this is the work’s US debut.

The mini moon– said to be about 1:500,000 in scale, with each centimeter representing 5km of the moon’s surface– is part of an immersive exhibit that’ll be open during Comic Con, today through Sunday. Audible is launching it to promote an audiobook, narrated by Dawson, of Artemis, a new novel by Andy Weir of The Martian fame.

When you think about sci-fi and dramatic readings, you think of one man: LaVar Burton, the Reading Rainbow host who also played Geordi La Forge on Star Trek: The Next Generation. (Okay, maybe you also think of Shatner, but forget that guy.) Needless to say, Burton was on hand at last night’s previous along with Neil deGrasse Tyson, which Rosario told everyone was “really fun.”

L to R: Andrew Gaies, Rosario Dawson, Luke Jerram, LaVar Burton.

She even took a crack at the beloved Reading Rainbow theme before reading the first couple of paragraphs of Artemis to an audience of fawning press members and students from the Lower Eastside Girls Club, where Rosario is on the board of directors. Check that out below.

“Museum of Artemis: Life on the Moon, Presented By Audible” is open at Classic Car Club of Manhattan, 1 Pier 76 (408 12th Ave.) from Oct. 6 and 7 from noon to 8pm and Oct. 8 till 4pm.
