This is a case study of the Thermal Protection System (TPS) currently in use on the Parker Solar Probe spacecraft, which over its seven year life it will experience surface temperatures in excess of 1400C. The traditional methodology for qualifying a space structure, using the old adage, "test what you fly and fly what you test" was simply not practical based on the selected materials, the size of the TPS, and a space environment characterized by its hard vacuumand hightemperatures. The approach to risk mitigation both in te ...

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 ...

Spacecraft power distribution unit test system re-use: Advantages, pitfalls and challenges The Solar Probe Plus (SPP) mission, part of NASA s Living With a Star program, is set to launch in July of 2018 on a trip to travel through the Sun s corona. The first component that will be integrated to the spacecraft is the Power Distribution Unit (PDU). The SPP PDU was based on the PDU design utilized for the Van Allen Probes (formerly Radiation Belt Storm Probes) mission, but with some very significant differences. Due to the fact that the SPP spacecraft is a much more complex vehicle, it requires nearly twice as many p ...

Data acquisition performance for deep space communications in solar probe plus frontier radio Radio receivers for deep space telecommunications require tracking loops that are robust in low signal-to-noise ratio conditions for not only carrier tracking, but also subcarrier tracking and bit synchronization. However, the loop band-widths must not be too narrow so as to accommodate Doppler dynamics, oscillator drift, and requirements for expedient and reliable data acquisition. The present work describes the data acquisition performance of Frontier Radio for the NASA Solar Probe Plus mission. The data acquisition time i ...

An active cooling system for the solar probe power system 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 R Lockwood, Mary; Ercol, Carl; Cho, Wei-Lin; Hartman, David; Adamson, Gary; Published by: 40th International Conference on Environmental Systems, ICES 2010 Published on: Cooling; Cooling systems; Orbits; Probes; Spacecraft; Testing; Thermoelectric equipment; Waste heat; Parker Engineering |
