Scientists have long known high levels of radiation exists on Mars. But could it be so high that humans won't be able to handle when we get there?

Going to Mars may be more dangerous than we thought. The major problem is high-energy space radiation. Scientists know that cosmic rays can damage DNA. They had just overlooked how bad it could get.

A team re-examined how damaged DNA can cause cancer. They then estimated levels of radiation exposure in space and on Mars. Their results are devastating.

The risk of cancer on Mars is twice as high as previously thought.
