The experimental technology, called Disruption-Tolerant Networking (DTN) protocol, could be a future way to communicate with astronauts on Mars...
...The DTN is similar to the internet on Earth, but is much more tolerant to the delays and disruptions that are likely to occur when data is shuttling between planets, satellites, space stations and distant spacecraft.
...The system uses a network of nodes - connection points - to cope with delays. If there is a disruption, the data gets stored at one of the nodes until the communication is available again to send it further.
This "store and forward" mechanism ensures data is not lost and gradually works its way towards its destination.

Basically space internet.
