A measly 25-30 years ago the first modems were sending data at 1Kbps, today we can send data through 7.5 billion kilometres of space at the same speed, i think that is pretty impressive.

The data rate to Mars isn't shabby, at about 230kbps, roughly four times the speed of a fast dial-up connection. I used to point that out when the only Internet at my folks' house was dial up. Eventually, my iPhone cell connection beat their dial-up connection and I stopped complaining.

  Cool, do you have a source for the 230Kbps ? i love to read about stuff like that.

    Data rate to the Mars Reconnaissance Orbiter can be up to 6Mbit/sec: https://en.wikipedia.org/wiki/Mars_Reconnaissance_Orbiter#Telecommunications_system https://en.wikipedia.org/wiki/Mars_Reconnaissance_Orbiter#Te...

      I couldn't even get DSL that fast at the last place I lived.

      Whoa, I didn't know that. I quoted the 230kbit number from memory, when I researched it several years ago, when my parents still had dial up. I'm not surprise that MRO is faster.

We could send a lot more data over that same distance if New Horizons had a large power supply. It was just limited by the plutonium supply available at launch.

  How much would theoretically be possible with current tech ?
