Simulation of the Solar Energetic Particle Event on 2020 May 29 Observed by Parker Solar Probe

This paper presents a stochastic three-dimensional focused transport simulation of solar energetic particles (SEPs) produced by a data-driven coronal mass ejection (CME) shock propagating through a data-driven model of coronal and heliospheric magnetic fields. The injection of SEPs at the CME shock is treated using diffusive shock acceleration of post-shock suprathermal solar wind ions. A time-backward stochastic simulation is employed to solve the transport equation to obtain the SEP time-intensity profile at any location, ...

Using Single-view Observations of Cometary Plasma Tails to Infer Solar Wind Speed

A comet plasma tail is a product of the interaction between the solar wind and the comet s coma, and has long been studied as a natural probe of the solar wind condition. We previously developed a method to derive the solar wind speed from dual-view observations of comet plasma tails. Here we improve the method to use single-view observations by assuming a radially propagating solar wind and apply it to two comets, C/2011 W3 (Lovejoy) and C/2012 S1 (ISON) observed by coronagraphs on board the Solar and Heliospheric Observato ...

Using Stereoscopic Observations of Cometary Plasma Tails to Infer Solar Wind Speed

Detection of the solar wind speed near the Sun is significant in understanding the heating and acceleration of the solar wind. Cometary plasma tails have long been used as natural probes for solar wind speed; previous solar wind speed estimates via plasma tails, however, were based on comet images from a single viewpoint, and the projection effect may influence the result. Using stereoscopic observations from the Solar Terrestrial Relations Observatory and the Solar and Heliospheric Observatory, we three-dimensionally rec ...

Advancements in hardware design for the frontier radio used for the solar probe plus mission

The Frontier Radio for the Solar Probe Plus mission offers a host of hardware design and manufacturing improvements. These improvements build on the technology readiness level (TRL)-9 radio platform that was flown on the Van Allen Probes mission in a duplexed S-band configuration and several development tasks funded by NASA Headquarters. Prior RF slice designs consisted of two separate circuit boards: one for lower frequencies and one for high-frequencies; advances in technology enabled the use of a high-frequency multilayer ...

Development of a flight qualified ka-band multi-chip module for the solar probe plus mission

The Johns Hopkins University Applied Physics Lab (JHU/APL) has developed a flight qualified, hermetically sealed, I/Q modulator Ka-band Multi-chip Module (MCM). Prototypes of this device have been developed over the years, but Solar Probe Plus (SPP) will be the first mission to use a flight qualified version of the MCM. This MCM enables a first for a deep-space mission: primary science data downlink with simultaneous data and navigation over Ka-band. SPP will also be the first JHU/APL mission to use Ka-band for downlink. The ...
