The practice of carrying arbitrary non-functional items into space, which has previously been carried out by many Space Shuttle missions, is evidence that space travel is still widely seen as special. The value of symbolic items increases enormously if the item has flown in space, due to the restricted access to space. The teddy bear being carried for charity will be auctioned at a much higher price than it would otherwise command. Scaled Composites employees were made to sign a contract forbidding them from selling the mementos they put on the flight.
