“Called Disruption Tolerant Networking, or DTN, the new technology will enable NASA and other space agencies around the world to better communicate with international fleets of spacecraft that will be used to explore the moon and Mars in the future. The technology is expected to lead to a working "Interplanetary Internet," said Kevin Gifford, a senior research associate at CU-Boulder's BioServe Space Technologies and a faculty member in the aerospace engineering sciences department.
"Communication between spacecraft and ground stations has traditionally been over a single point-to-point link, much like a walkie-talkie," said Gifford. "Currently, space operations teams must manually schedule each link and generate appropriate commands to specify where the data is to be sent, the time it will be sent and its destination. As the number of spacecraft and links increase and the need to communicate between many space vehicles emerges, these manual operations become increasingly cumbersome and costly," he said. “
