Een buitenaards bericht van aardse makelij
Manage episode 450973732 series 3424872
Op 24 mei vorig jaar werd een testbericht uitgezonden vanuit een baan rond de planeet Mars. Een en ander gebeurde ter voorbereiding op de dag dat we daadwerkelijk een buitenaards signaal ontvangen. Eerder dit jaar werd de boodschap eindelijk ontcijferd.
