|That is one huge paper airplane!|
With the help of a helium-filled weather balloon, the goal is to demonstrate just how durable these little cards are (there is a message inside each card for who ever happens to find it back on Earth).
Says one of the engineers involved with the project:
"I expect some will end up in the Siberian permafrost where they will remain until they thaw out thousands of years from now to be discovered by whatever post-human civilisation exists on Earth by then. A bond will be formed across the vastness of time thanks to our amazing space paper plane exploit!"Thankfully for those of us down on the ground, paper planes replaced the original plan to use lawn darts.
