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.

Retransmission depends on a reasonable probability of success on the first and certainly the second try.
Long delay paths make this even worse.
Multiple, less than stellar links in the retransmission path, even worse.
Hop by hop retransmission can improve the odds with multiple bad links.
(Think store and forward, like pre-internet networking.)
What do you do for the delays?
Probably a better retransmission control protocol than TCP, maybe also with some redundancy like FEC.
Did NASA publish anything on how this actually works?
