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 ...

Spacecraft level vibration testing exposes the as-built spacecraft, in its flight configuration, to the low frequency (<100 Hz) dynamic environment experienced during launch with the primary objective of verifying structural integrity and system performance. This test requires as flight-like of a configuration as possible and is therefore typically one of the last tests performed in the spacecraft verification program. At this level of integration (spacecraft), failures pose a much greater risk to the program than at lower l ...

Solar probe plus solar array cooling system T-Vac test The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, is designing and building the Solar Probe Plus (SPP) spacecraft and managing the project for NASA s Living with a Star (LWS) program. The main objectives of the SPP mission are to understand the Sun s coronal magnetic field, the causes of solar corona and solar wind heating and acceleration, and the mechanisms of energetic particles acceleration and transportation. To achieve these objectives, the SPP spacecraft needs to make in-situ measurements in ...

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 ...

LEON3FT proton SEE test results for the solar probe plus program The Solar Probe Plus program requires a low power microprocessor with demonstrated capability to resist SEE in a high proton flux environment. Proton tests conducted at IUCF successfully demonstrated the single bit error correction capability of the LEON3FT. The test setup and results are summarized. © 2011 IEEE.

Array-design considerations for the solar probe plus mission The NASA Solar Probe Plus (SPP) mission will fly into and study the Sun s corona, reaching as close as 8.5 solar radii from the surface of the Sun. Power generation for the spacecraft will be provided by two solar array wings, which are being designed and built by Johns Hopkins University Applied Physics Laboratory and Emcore Photovoltaics. SPP will get closer to the Sun than any previous mission, and the solar array will therefore need to operate reliably under unusually high irradiances, temperatures, and angles of inciden ...
