Did you know you can send a postcard to Space and get it sent back to you stamped with “Flown to Space”?
I haven’t tried it yet as I’ve only just come across the project. However, it’s free to join (you just pay postage on the card you send) and its open to anyone, anywhere in the world!
I hadn’t heard of the “Flown to Space” idea until now. It’s a cool idea, but I personally wouldn’t want to be involved with anything having to do with Jeff Bezos, considering the stories I’ve read about how his company treats its employees.
On a somewhat related note, there were mail-delivering experiments years ago via something referred to as “Rocket Mail.” Unfortunately, some of the letters and postcards that were transported via rockets sometimes tended to get blown up, or at least heavily singed, upon landing back on earth. Attached is a link to a Wikipedia article about rocket mail.
