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 ...

Verification and validation testing for the parker solar probe guidance and control system

Parker Solar Probe was launched on a 7-year mission to explore the Sun in August 2018. A successful first orbit was preceded and enabled by a rigorous test campaign prior to launch. This paper discusses two of the main portions of that test program used to characterize and verify the performance of the spacecraft’s guidance and control system. An extensive set of stand-alone simulations was designed to demonstrate compliance with performance requirements and explore system behavior in response to a large set of fault c ...

Initial attitude control challenges for the solar probe plus spacecraft

The Solar Probe Plus (SPP) mission plans to launch a spacecraft to explore the Sun in 2018. Attitude control is maintained with a 3-axis stabilized, closed-loop control system. One of the first tasks for this system is acquiring attitude knowledge and establishing attitude control after separation from the launch vehicle. Once control is established, the spacecraft must be moved through a sequence of attitudes to meet power and thermal constraints and reach a powerpositive state. This paper describes the options selected for ...

Solar Probe Plus Spacecraft Flight Software requirements verification test framework

Comprehensive Spacecraft Flight Software requirements verification is essential to the success of deep space missions. NASA s Solar Probe Plus (SPP) Spacecraft Flight Software and requirement verification activities are being implemented by Johns Hopkins University Applied Physics Laboratory (JHU/APL) located in Laurel, MD. JHU/APL s software development process for a critical mission requires an independent verification of all Spacecraft Flight Software requirements. The complexity of SPP s Spacecraft Flight Software and th ...

Solar probe plus (SPP) dynamic solar array simulator

The Solar Probe Plus (SPP) mission, under NASA’s Living With a Star program, will fly a spacecraft (S/C) through the sun’s outer corona with orbit perihelia that gradually approach as close as 9.86 solar radii from the center of the sun. The mission will gather data on the processes of coronal heating, solar wind acceleration, and production, evolution, and transport of solar energetic particles. The S/C is powered by two actively cooled photovoltaic solar array (S/A) wings. Because of the extreme environments ne ...

Modeling the near-sun environment for the Solar Probe Plus Guidance and Control system

The Solar Probe Plus (SPP) mission is the culmination of decades of studies on spacecraft designed to explore the inner region of the heliosphere. The mission is being implemented by the Johns Hopkins University Applied Physics Laboratory for a 2018 launch. Building on the flight experiences of the Helios (NASA/FRG) and MESSENGER (NASA/JHUAPL) spacecraft and several remote studies, SPP will be the closest operating spacecraft to the Sun, even surpassing the 2017 planned launch of the Solar Orbiter (ESA/NASA) spacecraft. At a ...

Active solar array thermal control system for the solar probe plus spacecraft

The Solar Probe Plus (SPP) spacecraft will orbit the Sun closer than any other previous probe. As dictated by the current mission design, the spacecraft will achieve many perihelia as close as 9.5 RS from the Sun. During those passes, it will encounter a solar flux of ~500 suns, or 70 W/cm2. This flux is more than 50 times larger than the solar heating seen by any previous spacecraft. During the entire mission, the spacecraft and science instruments will be protected by a Thermal Protection System (TPS), and elect ...
