Virgin Galactic is a commercial company which idea is to make money. Virgin Galactic has been selling trips to the space since 2005 and now they are starting to publish books. Other products will soon follow. Think what kind of products are sold under Angry Birds-logo. The first book will be published this October. As far I know, Virgin Galactic is not going to sell any rocket-boxers. Luckily you can buy rocket-boxers from my shop.
