Solar Array Pointing Requirements Development for the Psyche Spacecraft
Pointing the solar array to the Sun is critical for the power management in all so-lar-powered space missions. This is particularly true for NASA’s Psyche mis-sion, which will explore the large asteroid (16) Psyche orbiting the Sun at around 3 AU. Due to the large distance to the Sun, use of electric propulsion, and sophisticated scientific orbits at Psyche, the definition of this pointing accu-racy became a challenging task for the spacecraft design, which involves the GNC, Power, and Thermal subsystems as well as Mission Design. This paper describes the story of how this complicated requirement development evolved for Psyche mission.

Sun search desgin for the Psyche spacecraft
Psyche is a scientific mission to explore the large asteroid (16) Psyche that orbits the Sun at ~3 AU. Managed by JPL, it is the first instance of Maxar’s product line of geosynchronous communication satellites being repurposed for deep space. This paper presents the design of a unique sun sensor configuration for Safe Mode of the spacecraft. It enables quick, robust, and propellant-efficient safing while leveraging sensors, avionics, and algorithms that have extensive, flight-proven heritages
