It might be hard to fathom now, but the human exploration of the solar system isn’t going to stop at the moon and Mars. Eventually, our descendants will spread throughout the solar system—for those interested in space exploration, the question is only of when rather than if. Answering that question is the focus of a new paper released on arXiv by a group of researchers from the U.S., China, and the Netherlands. Their approach is highly theoretical, but it is likely more accurate than previous estimates, and it gives a reasonable idea of when we could expect to see humans in the outer solar system. The latest they think we could reach the Saturnian system is 2153.
