Ever since we've been sending spacecraft out into the universe, we've sent little bits of cargo with them. Be it for hope and optimism, the preservation of our culture, or an olive branch of sorts to whomever might find it drifting out there in space, human beings have long been fans of the ultimate messages in a bottle. From the famous golden records on Voyagers 1 and 2, to an astronomer's ashes speeding past Pluto, Kovi and Benjamin take a look at messages humans have sent to space and are planning to send to space. And if you're planning a trip to Mars, watch out for Elon's car.
