We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects.

Hello from above our magnificent planet Earth.

It's such a long mission and we get to spend so much time in space... we're doing such exciting research. And I don't want to overemphasize the life science research, but as a physician the life science research that we're doing is extremely exciting.

Phone networks can capture life on our planet.

Life science research can be done on multiple platforms. Since we have a very small number of people flying into space, the more people you have, the better.

We love our planet Earth. We should - it is our home, and there's no place like home. There can't ever be a better place than Earth.
