NASA and ESA Experimented Interplanetary Internet to Test Robot from ISS

NASA and also the European area Agency (ESA) with success have used Associate in Nursing experimental version of celestial body web to manage an academic rover from the International artificial satellite. The experiment used NASA’s Disruption Tolerant Networking (DTN) protocol to transmit messages and demonstrate technology that someday could modify Internet-like communications with area vehicles and support habitats or infrastructure on another planet.

Space station Expedition thirty three commander Sunita Williams in late Gregorian calendar month used a NASA-developed portable computer to remotely drive atiny low plaything golem at the ecu area Operations Centre in Darmstadt, Germany. The European-led experiment used NASA’s DTN to simulate a situation within which Associate in Nursing cosmonaut in an exceedingly vehicle orbiting a planetary body controls a robotic rover on the planet’s surface.

“The demonstration showed the practicableness of employing a new communications infrastructure to send commands to a surface golem from Associate in Nursing orbiting artificial satellite and receive pictures and information back from the golem,” aforesaid Badri Younes, deputy associate administrator for area communications and navigation at independent agency Headquarters in Washington.

“The experimental DTN we’ve tested from the artificial satellite could someday be utilized by humans on a artificial satellite in orbit around Mars to control robots on the surface, or from Earth victimization orbiting satellites as relay transmitters.”

The DTN design could be a new technology that permits standardized communications the same as the net to perform over long distances and thru time delays related to on-orbit or part artificial satellite or robotic systems. The core of the DTN suite is that the Bundle Protocol (BP), that is roughly resembling the net Protocol (IP) that is the core of the net on Earth. whereas scientific discipline assumes a nonstop end-to-end information path exists between the user and an overseas area system, DTN accounts for disconnections and errors. In DTN, information move through the network “hop-by-hop.” whereas expecting future link to become connected, bundles ar briefly keep then forwarded to future node once the link becomes on the market.

NASA’s work on DTN is an element of the agency’s area Communication and Navigation (SCaN) Program. SCaN coordinates multiple area communications networks and network support functions to control, maintain and grow NASA’s area communications and navigation capabilities in support of the agency’s area missions.

The artificial satellite conjointly is a platform for analysis centered on human health and exploration, technology testing for sanctioning future exploration, analysis in basic life and physical sciences and Earth and area science.
