It's the normal data cost. EG the Landsat data is stored in S3, so it's free to EC2 (in the same region), and somewhere around $0.09/gb to the public internet.

However, the idea is not that you download it all (there's probably cheaper ways to acquire Landsat data), the idea is if you want to do whatever analysis on AWS, they've already got it neatly ingested for you.
