The Australian Centre for Space Photonics
Raison d'etre
To expand unique Australian capabilities and experience
to progress research into key technologies for an interplanetary high-data rate
optical communications link that are synergistic with near term space communication
needs.
System Concept - a telescope with laser transmitter in Mars orbit, comparable in
size to the Hubble Space Telescope, acts as a communications relay for Mars probes to send their
data back to earth at high data rates in a beam of light. A receiving station might be on the
Earth's surface as shown here, or in Earth orbit.
Image assembled using photos of planets from NASA's photojournal. (higher resolution version here, and of a space-based
receiver concept here)
