ExoBiosphere sends patient cancer cells and experimental drugs to space, where microgravity makes tumors grow fast enough to test thousands of drug combinations in orbit. They return the data and samples to help researchers find cures for lethal cancers.

Our mission at ExoBiosphere is to extend and improve health on Earth and also in space. And we do that by finding cures in space. Brain cancer, blood cancer, breast cancer, colon cancer, the most debilitating and destructive diseases on Earth can be cured in space.
You can grow a cancer super fast in space. Then how is that going to help us solve cancer?
What our customers are paying us for is for the entire turnkey service. So they provide us with their cells and the drugs they want to test. We ship it up to space, we conduct the tests, and then we bring back that data and their cells and give it back to them. There is no system like this that can conduct the throughput. We're talking about thousands of tests that are being conducted. This is just the beginning of something extremely exciting.
