Space tourism is a thing in 2018. Elon Musk says two people have signed up with SpaceX to take a trip around the moon, and Richard Branson has hundreds registered for a similar program through Virgin Galactic.
But space and aviation medical specialist Rowena Christiansen won’t be among these volunteer travellers. Apart from the cost, Rowena’s knowledge of the practical barriers, training requirements and medical demands of space travel will keep her on the ground in the near future. Rowena explains her position in the first piece of our new series Take it From Me, where we find an expert to provide a personal but informed perspective on a topical issue.
Take it From Me joins other regular editorial products we’re now running on The Conversation - including Sustainable Shopping, Curious Kids, Five Experts, The economics of and the Friday essay.
