Using software with the name disruptions-tolerant Networking, abbreviated DTN, were data such as pictures of the universe sent to a space vehicle Unmanned that 32 million kilometers from earth to float through space, NASA reported on its website.
Solar wind resistant

NASA developed this technology by Vint Cerf and Google, when the two companies a decade ago decided to cooperate. The two giants in their own areas since that time with several projects together. For example, Google Earth uses technology from NASA.

"This is the first step towards developing a new space communications capabilities. An interplanetary Internet," said Adrian Hooke, team leader of the space department at NASA-networking architecture.

The connection in the universe must withstand a couple stootjes can. Thus, space vehicles behind planets or solar wind can influence the connection. The DTN connection works so differently than TCP / IP networks on earth. As a final connection is not found, the information does not disappear but retains it until the connection is found.
Connection to Mars

The delays can send information to, for example, according to NASA Mars up to twenty minutes. But that latency is variable because the distance between Earth and Mars enormous changes. Because the two planets pass several times to have the sun varies the distance between the 60 million miles and 380 million kilometers.
ISS

The intention is that the DTN software in the next round test is added to the system of the international space station ISS. The station is located in orbit around the earth at a modest distance of about 340 kilometers
