Large antennas and powerful transmitters are necessary to maintain a stable communication link with Earth. The mission also requires autonomous systems that can operate the spacecraft and collect data without constant human intervention. Data storage and management are also crucial, as the spacecraft will collect vast amounts of scientific data that need to be transmitted back to Earth.
Developing Instruments for Extreme Conditions
Developing scientific instruments that can function reliably in the extreme conditions of the outer solar system is essential. The instruments must be able to withstand low temperatures, high levels of radiation, and the stresses of long-duration spaceflight.
