Leaving the EU with no negotiation means no flights to europe or the U.S. Overfly rights still exist because the UK signed up to Chicago Convention. There's a fair few countries where the UK will still have rights to fly to - Singapore for one, I suspect much of Africa too. The UK is a member of the Outer Space treaty, has been since 1967, so I don't think there's a technical hurdle to launching a rocket from Brexit Britain (Assuming the fuel and rocked is already on the island). (Of course whether we can afford to when we can't export any goods is another matter)
