Disruption tolerant networking to demonstrate Internet in space

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.
