Space Communications and Navigation (SCaN)
NASA's reliable space communications and navigation (SCaN) networks are the backbone of all of NASA's space missions, providing the critical communication services for all Earth, space science, and human space flight missions. This includes all of the telemetry, tracking, and commanding (TTandC) required by each spacecraft to transfer key data to the ground systems to manage space operations, as well as the voice communications with the human space flight missions and data transfer for all of the Earth and space science missions. These networks enable NASA to show the live broadcasts to the public of exciting events including launches, astronaut extra-vehicular activity (EVAs), life and work on-board the International Space Station (ISS), and the Mars Rovers' exploration of our neighboring planet.

NASA's amazing successes, like the landing of the Mars Rovers and their journeys across the red planet, as well as the tragedies during our history have all been brought to the American people live and unfiltered through these communication networks. The Earth science data from the many spacecraft studying our home planet are all made available to scientists through these networks, to learn about our climate and help protect our home planet.

Review Status: SCaN was chartered as a project review by the HEOMD. The SCaN PIR is scheduled for September, 2012.
