Parker solar probe structural-thermal analysis challenges The NASA Parker Solar Probe spacecraft, built by the Johns Hopkins University Applied Physics Lab will fly through the outermost part of the Sun s atmosphere taking in situ measurements and imaging to improve our understanding of the corona and the solar wind. The Thermal Protection System (TPS), a 4.5-inch thick carbon-composite heat shield, limits heat transfer to the spacecraft during its flight through the Sun s atmosphere, and casts a shadow which protects the spacecraft and its instruments from the harsh thermal enviro ...

Design of a spacecraft integration and test facility The Johns Hopkins University Applied Physics Laboratory (JHU/APL) is dedicated to solving critical challenges as set forth by the National Aeronautics and Space Administration and the Department of Defense. JHU/APL participates fully in the nation s formulation of space science and exploration priorities, providing the needed science, engineering, and technology, including the production and operation of unique spacecraft, instruments, and subsystems. Built in 1983, JHU/APL s spacecraft integration and test facility has supp ...

Thermal design for high-temperature high-irradiance testing of space solar panel components Emcore has been performing High Intensity High Temperature (HIHT) tests on covered, interconnected cell (CIC) assemblies. End-of-life performance of spacecraft solar panels depends to a great extent on changes in the optical properties of the CICs coverglass adhesive during the mission. An important change in silicone coverglass adhesives is observed as degradation of short wavelength transmission, often called darkening or yellowing . This is understood to be driven by exposure to high intensity UV and by exposure to el ...

This paper describes the implementation of a solar simulator, know as the Solar Environment Simulator (SES), that can simulate solar flux levels up to those encountered at 9.8 solar radii. The paper outlines the design, and the challenges of realizing the SES. It also describes its initial uses for proving out the design of the Solar Winds Electrons, Alphas, and Protons (SWEAP) Faraday cup. The upcoming Solar Probe Plus (SPP) mission requires that its in-situ plasma instrument (the Faraday Cup) survive and operate over an un ...
