NASA tests 'deep space internet'
(11-19 10:09)
The US space agency NASA said it successfully conducted a first test of a deep space communications network modeled on the internet.
"This is the first step in creating a totally new space communications capability, an interplanetary internet,'' said Adrian Hooke, NASA's manager of space-networking architecture, technology and standards.
The US space agency said Jet Propulsion Laboratory engineers used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA spacecraft some 32.4 million kilometers from Earth.
NASA said the software protocol, which must be able to withstand delays, disruptions and disconnections in space, was designed in partnership with Vint Cerf, a vice president at internet search giant Google.
