Robotic exploration of the solar system using small satellites (SmallSats) is gaining popularity because of SmallSats’ lower cost and faster development cycle compared to primary science missions. A potential obstacle for deployment of SmallSats in

In space communications, standard link analysis assumes that messages are sent once. For a communication link that uses an error-correction coding scheme, bit-error-rate (BER) or frame-error-rate (FER), and link margins are common metrics that charac

Recently, JPL mission designers have been investigating prospects for a Mars 2018 mission. The possibility of such a mission is being examined, at the request of NASA HQ, in the wake of NASA's departure from ESA's ExoMars missions, as well as to supp
