COMING UP:Share Opener Variant 3



Working and living on board the International Space Station is the best place you could possibly wish as a professional to be. You're in an environment where you're so well supported, you're very aware that you're doing absolute cutting edge technology. In one day, you may be touching six or seven experiments in one day.
And you're very aware that these experiments are the result of hundreds if not thousands of people in each of their areas of speciality. And you're the person who's executing this and running the experiment in low Earth orbit. So it's a hugely privileged place to work, and that is very rewarding and very satisfying.
So I would go back in a heartbeat.
