Decoder Synchronization for Deep Space Missions
The Consultative committee for Space Data STandards (CCSDS) recommends that space communication links employ a concatenated error-correcting channel-coding system in which the inner code is a convolutional (7, 2/2) code and the outer code is a (255,223) Reed-Solomon code.

Directed-energy propulsion architecture for deep-space missions with characteristic velocities of order 100 km/s
This paper investigates the feasibility of a propulsion system architecture that may enable missions with characteristic velocities in the range 100 to 200 km/s. The conceptual architecture is based on the use of a kilometer-scale, space-based, phased-array laser with an output power of hundreds of megawatts that beams power over distances up to 40 au to a receiving vehicle.

Autonomous Optical-only Navigation for Deep Space Missions
Navigation of spacecraft for interplanetary missions is typically performed on the ground using a two-way radio link to obtain the necessary tracking data. Due to the limited number of antenna capable of tracking these spacecraft, it would be advantageous to have a navigation capability that is entirely self-contained onboard a spacecraft. A camera mounted on a spacecraft is theoretically capable of enabling self-navigating spacecraft, and has been demonstrated in limited circumstances in past missions. Fundamentally, the technique involves using various natural or artificial targets as observational beacons to determine the observers position in space. In this paper, the technique of optical-only navigation is described, including discussions of what types of observations are used, and results of analysis showing the accuracies achievable for various mission types across the Solar System is discussed.
