Those accelerator-ring people may have an idea, but do they have a roadmap? Because as of today, space elevator pioneers Liftport certainly do, outlining where they think the major landmarks of progress will be on their journey towards building a ‘beanstalk’. It’s a working document, subject to change with feedback from experts and the public, but they’re boldly stating their intents to the world. I expect they’re also pretty stoked by the news that the Spaceward Foundation now has a prize purse totalling $4million for forthcoming space elevator development contests.
