DARPA’s Launch Challenge offers $10M prize for short-notice, rapid-turnaround rocketry

Getting to space is already tough, but getting there on short notice and then doing it again a couple weeks later? That's a big ask. Nevertheless, DARPA is asking it as part of its Launch Challenge, announced today at the 34th Space Symposium in Colorado. Teams must take a payload to space with only days to prepare, then do it again soon after — if they want to win the $10M grand prize.
