Showtime Bows Idiots in Space Comedy Moonbase 8

As you might expect of three would-be astronauts played by Fred Armisen, Tim Heidecker and John C. Reilly, they're not the sharpest tools in the shed, but they make up for it with blind faith and a can-do attitude. Co-created by Armisen and his Portlandia executive producer Jonathan Krisel, Moonbase 8 premieres Sunday on Showtime.

Also this weekend: The Mandalorian continues his mission, Seduced: Inside the NXIVM Cult wraps its critically-acclaimed four-episode run on Starz, and — in what's fast-becoming a tradition — Dave Chappelle hosts SNL's post-election episode. Here's what's new and noteworthy on TV this weekend:
