In a time if pillaging, burning, and all out war, Vikings who'd fallen in battle would be sent to sea in a boat. A comrade would set the boat aflame with a blazing arrow, and the spirit of the fallen warrior would rise to Valhalla.
Recently I found out that there's a guy buried on the moon. <- Read it again. On the moon. Not only that, several people have had their remains sent to space in lieu of a traditional funeral. As a physics major, it's only natural that I should want this. Also, I'm in nuclear physics, so they have to nuke the ship once it's in deep space.
Tl; dr. Valhaley's Comet, here I come. I'm gonna be a Space Viking.
