Research into manned spaceflight is shifting from low-Earth orbit to destinations much further away, like Mars and the asteroid belt. But society will have to invent many new technologies before it can plausibly send people to those distances.

I work a lot with my ski sponsor, Head, to develop new technologies.

Many new technologies come with a promise to change the world, but the world refuses to cooperate.

Critics are not creators. They rarely write great novels, invent new technologies, or come up with a great business idea.

Designing a station with artificial gravity would undoubtedly be a daunting task. Space agencies would have to re-examine many reliable technologies under the light of the new forces these tools would have to endure. Space flight would have to take several steps back before moving forward again.

New technologies, however remarkable they might seem, are fundamentally just tools made by people for people.
