SCaN is at the forefront of space communications and navigation technology development, pushing the boundaries of what’s possible to better enable space and science missions. Technology projects are developed by groups of SCaN Engineers and scientists. The technology items are created and tested in lab settings before they are taken into space for further testing. Once a technology has proven itself worthy in a space environment, it can then be utilized on missions.
SCaN Engineering and Technology
Delay/Disruption Tolerant Networking
Delay/Disruption Tolerant Networking is a suite of standard protocols that uses information within the data stream to accomplish end-to-end data delivery through network nodes.

space communications and navigation
NASA’s Space Communication and Navigation program, or SCaN, serves as the program office for all of NASA’s space communications operations. Over 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to monitor Earth’s weather and effects of climate changes, support lunar exploration, uncover the solar system and beyond, and peer back in time to understand the origins of the universe.
