The techniques for stray light analysis, optimization and testing are described for two space telescopes that observe the solar corona: the Solar Orbiter Heliospheric Imager (SoloHI) that will fly on the ESA Solar Orbiter (SolO), and the Wide Field Imager for Solar Probe (WISPR) that will fly on the NASA Parker Solar Probe (PSP) mission. Imaging the solar corona is challenging, because the corona is six orders of magnitude dimmer than the Sun surface at the limb, and the coronal brightness continues to decrease to ten orders ...

Full wing qualification testing and incremental program update for the solar probe plus array As the Solar Probe Plus (SPP) program moves into the flight hardware build phase, the final testing of the qualification panel has been completed. The rigorous testing is many orders of magnitude more intensive than that used for standard earth-orbit missions. Testing under high irradiance, high temperature conditions over large areas poses design and logistic challenges, which have spurred innovation in steady state illumination. New test hardware of interest include a large area LED simulator capable of 6X AM0 string curre ...

Outgassing modeling for solar probe plus The spacecraft for the Solar Probe Plus mission, due to launch in 2018, will encounter an extreme near-Sun thermal and plasma environment. Outgassing of materials such as silicone adhesives in this previously unexplored environment can result in deposits on solar arrays, instrument components, and other sensitive spacecraft surfaces. Array surfaces exposed to UV can cause those deposits to be fixed to the surface, degrading their performance. To assess the severity of the deposits, the Solar Probe Plus program has undertaken ...

Predicting the solar probe plus solar array output Predicting the output of the Solar Probe Plus (SPP) solar array presents unique challenges as the array operates at very high temperatures and irradiances, and has a water-cooled substrate. A further complication arises because, close to perihelion, each string operates at an irradiance and temperature different from the other strings. This paper provides the methodology and results for computing the output of the array over a range of irradiances from zero to seventy suns, temperatures from -80°C to 164°C, and angle ...

Extreme temperature thermal vacuum testing of the solar probe plus radiator The Solar Probe Plus (SPP) spacecraft is equipped with four thermal radiators as part of the solar array cooling system. This cooling system rejects the heat absorbed by two high heat flux solar arrays. Each thermal radiator is comprised of nine aluminum radiation fins that are bonded with epoxy to titanium tubes. These tubes are connected together via inlet and outlet manifolds to create each radiator assembly. The solar arrays are cooled by micro-channel-etched titanium plates through which the working fluid, water, is for ...

A first look at the guidance and control system for the Solar Probe Plus mission The Solar Probe Plus mission plans to send a spacecraft to explore the inner region of the heliosphere and is currently working towards launch in 2018. Protection from the harsh solar environment is accomplished with a large thermal protection system (TPS), which includes a large shield protecting most spacecraft components and instruments from direct exposure to the Sun. Reliable attitude control is needed to keep the TPS shield between the main body of the spacecraft and th ...
