NASA’s Jet Propulsion Laboratory (JPL) installed and tested elements of the Disruption Tolerant Networking (DTN) on the Deep Impact/ Extrasolar Planet Observation and Characterization (EPOCh) and Deep Impact eXtended Investigation (DIXI) – EPOXI spacecraft. DTN is a type of interplanetary internet that stores information when transmissions are interrupted and forwards that information to its destination using relay stations. This DTN experiment called Deep Impact Network Experiment (DINET) transmitted about 300 images from the JPL nodes to the spacecraft and back to the nodes. In the following years, DTN has also experimented on the International Space Station and through a pulsed laser beam from the Moon.
