NASA and ESA-successful LEGO robot control system space by Interplanetary Internet

NASA and the European Space Agency (ESA) has recently successfully control a LEGO robot on the International Space Station (ISS) from the ground thanks to the Interplanetary Internet system is in the process of testing ("Interplanetary "means between the planets with each other). This system uses protocols Disruption tolerant Networking (DTN) to transmit a signal, which was developed for a large-latency environments such as space. Before NASA also tested the spatial data transfer in this network.

Interplanetary Internet

Explain more about DTN, NASA said its core is the Bundle Protocol (BP), similar to the Internet Protocol (IP) are widely used in our Internet. In DTN, data will move by short hops between the "button", while in IP, in a continuous path from one point to another in the network. These buttons can be satellite or relay stations. DTN will retain data and only sent when a node can establish secure links to the next node, thus the data packets will not be lost, the error is minimized. NASA expected using DTN to build a complex network between the planets with each other in the future, so that the communication between the Earth and the means of transport in space or infrastructure in the planet other more easily.
