This isn't a question about New Horizons but it does relate to the Kuiper Belt/outer zone of the solar system. I've heard that there's a statistical possibility that there could be more large planets the size of Mars or even Earth beyond the Kuiper Belt, but if they do exist, we don't have the technology to detect them.

How long do you think it will take before we have the technological capabilities to discover these possible objects?

How long before New Horizons arrives do you expect to start seeing any new moons? I know you guys saw Hydra last month where the spacecraft was. When do you think you'll be able to start finding new ones beyond the known 5?
