Communications subsystems for furture missions must be low-mass and enable equivalent if not great data return to the scientific community over the current X-band (8.4 GHz) links.
One of the NASA technology development program at the Jet Propulsion Laboratory aims to increase the information return capability while reducing the size of the spacecraft via laser communications.

A CCD-based spatial acquisition and tracking subsystem has been developed to perform both spatial acquisition and tracking functions for a lasercom instrument. By operating the CCD in the.
NASA's space missions of the future will be dominated by more moderate sized mini- and micro- spacecraft. Such missions will place stringent requirements on the mass and power consumption required for the various spacecraft subsystems.
