Arthur T Knackerbracket has found the following story:

NASA's Human Exploration and Operations and Science Mission Directorates are collaborating to make interplanetary Internet a reality.

They're about to demonstrate Delay/Disruption Tolerant Networking, or DTN -- a technology that sends information much the same way as the conventional Internet does. Information is put into DTN bundles, which are sent through space and ground networks to its destination.

The Science Mission Directorate looks forward to incorporating DTN into future missions and has identified the Plankton, Aerosol, Cloud, ocean Ecosystem, or PACE, mission as the first key opportunity to demonstrate this revolutionary capability.

    You don't need to re-transmit lost packets if you use FEC (forward error correction). Old tech is good tech!

    FEC will correct corrupted packets, as long as the number of corrupted bits stays within a specified limit. Packets that are corrupted more than that, will need to be retransmitted.
