The first Internet set-up in space has been successfully concluded, with NASA having having tried out a deep space communications network modelled on the Internet.

Engineers used Disruption-Tolerant Networking (DTN) software to trnsmit images of space to and from a NASA spacecraft.
The experiment took place about 32,4-million kilometres from Earth.
Vint Cerf, the inventor of TCP/IP and currently a vice-president at Google, helped to develop the software.
DTN is very tolerant of delays and doesn't assume the receiving system is available at all times.
