Solar Radiation Disturbance Torque Reduction for the Parker Solar Probe Observatory
This paper examines the methodology used for reducing solar pressure disturbance torques for the Parker Solar Probe (PSP) Observatory by minimizing the offset between spacecraft s Center of Gravity (CG) and Center of Pressure (CP). The force due to solar radiation pressures encountered by the PSP spacecraft, particularly at the 9.86 solar-radii (Rs) closest approach point in the orbit, are of a sufficient magnitude to produce significant disturbance torques. Inside of 0.25 AU, the Observatory is required to keep its Thermal ...

Risk reduction of integration and testing operations using augmented reality on Parker solar probe
Flying a spacecraft involves significant risks, but building and testing should not have to. At the Johns Hopkins University Applied Physics Laboratory (JHU APL), the Parker Solar Probe (PSP) program has leveraged Augmented Reality (AR) to reduce risks involved with mechanical integration and testing (I&T) operations of the spacecraft. Three major contexts benefitted using AR tools: 1) design and rehearsal of integration sequences and procedures, 2) planning and preparing for flight system level testing, and 3) communication ...
