Watch it

“In the Shadow of the Moon” (7 p.m., Green). A supercool 2007 documentary film chronicling the rise of America’s space program in the ’60s and early ’70s, featuring a ton of rare archival NASA footage.

“You Don’t Know Jack” (9 p.m., HBO). Al Pacino stars in this Barry Levinson-directed biopic of Dr. Jack Kevorkian, who gained national infamy in the ’90s for aiding the suicides of terminally ill patients. It’s getting great reviews (click here for the LA Times and Boston Globe say about it).

“Saturday Night Live” (11:30 p.m., NBC). Gabourey Sidibe (“Precious”) hosts, with musical guests MGMT.

Catch a score

Stanley Cup Playoffs: Sharks vs. Avalanche (7 p.m., CSN-CA). San Jose’s up 3-2, and can clinch the series with a win tonight in Denver.

Record it

“Doctor Who” (9 p.m., BBC America). Last week’s season premiere was the network’s highest-rated show ever. Huh. You can watch a repeat of that episode at 8, then a new one at 9 tonight that has the new Doctor visiting an abandoned Earth in the distant future.

Skip it

“Mothman” (9 p.m., Syfy). I’m so glad Syfy changed its name so it wouldn’t be pigeonholed as the sci-fi network. Now they can be  known as the low-budget, dumbass-movie-of-the-week network.
