Celebrate the 35th anniversary of the launch of Voyager 2 (it rocketed off Earth on 8/20/77 carrying a copy of the Golden Record), and tip your hat to the Mars rover Curiosity as it kicks off its third week on the red planet, with a rebroadcast of one our favorite episodes: Space.

We've been space-crazy the past few weeks here at Radiolab -- from cheering on the scientifically epic landing of the Mars rover earlier this month, to staying up late to watch the Perseid meteor showers, to reliving a stomach-churning spacewalk with an astronaut in our live show In the Dark. We've been happily turning our thoughts and gazes skyward all summer long. So before the nights get too chilly, grab a blanket, cue up Space, and stare into that vast, glittering, perspective-shaking darkness with us.
