Interplanetary road trips take a WHILE. So for this episode of Voyages to Mars, while we cruise onward towards the Red Planet, we’re listening to some poetry that pays tribute to long duration space travel.

This month, gas giants Jupiter and Saturn are coming together in the sky for a once-in-a-lifetime event called a great conjunction. It will peak on December 21, 2020.
