Worse, the ping changes a lot. From 3 minutes to theoretical 22, but if Mars and Earth are separated by the Sun, you would have to communicate through a relay, adding possibly other 10 minutes.

Mars will be a digital frontier forever, or until someone discovers communication faster than light, which is impossible in our current model of physics.

I wonder how telecom would work for such a system. What would it be like to sit down at a computer, or open up your phone, and access a web page hosted on another planet? Would everything be mirrored to the local internet and synchronized periodically? Would you simply not be able to participate in most features we take for granted on the current web?

Ordering anything from Earthly e-shops would certainly be a challenge :) No free same day delivery there, unless you bought some downloadable stuff!

I guess the contents of planetary Internets will just be synchronized periodically, the physical limitations do not really allow for a different solution.
