The Solar Probe Plus Mission: Humanity\textquoterights First Visit to Our Star Solar Probe Plus (SPP) will be the first spacecraft to fly into the low solar corona. SPP\textquoterights main science goal is to determine the structure and dynamics of the Sun\textquoterights coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what processes accelerate energetic particles. Understanding these fundamental phenomena has been a top-priority science goal for over five decades, dating back to the 1958 Simpson Committee Report. The scale and concept of su ...

Estimating Upper Limits of Solar Flare Hard X-Ray Fluences for Space Missions Near the Sun We present a method to estimate an upper limit of the mission integrated fluence of hard X-rays (HXRs) produced by solar flares for a probe traveling at heliocentric distances R<1 AU. By using (1) the number and peak of both soft X-ray (SXR) flares and microwave (MW) solar bursts observed during the last three solar cycles, (2) either frequency distributions of HXR flare parameters, or correlations between the HXR fluence and the SXR flare class or the MW burst flux intensity, and (3) virtual launches of the probe at differe ...

A method to estimate both solar energetic particle mission-integrated fluences and solar energetic particle peak intensities for missions traveling through the innermost part of the heliosphere (r \< 1 AU) is presented. By using (1) an extensive data set of particle intensities measured at 1 AU over the last three solar cycles, (2) successive launch dates for the mission traveling close to the Sun over the time interval spanned by our data set, and (3) appropriate radial dependences to extrapolate fluences and peak int ...

The Solar Probe Plus solar array development and design The Solar Probe Plus (SPP) spacecraft will orbit as closely as 9.5 solar radii from the sun; so close that its thermal protection shield (TPS) will reach a peak temperature of 1,400C. To work in this environment, the solar array will use pressurized water cooling and operate in the penumbra formed by the TPS at a 68° angle of incidence. Even with these mitigations, the array will be subject to extremely high intensity and temperature. This paper will summarize the array s environment, present a preliminary design, outlin ...

Solar probe plus, a historic mission to the sun Solar Probe Plus (SPP) will be the first mission to fly into the low solar corona, revealing how the corona is heated and the solar wind is accelerated, solving two fundamental mysteries that have been top-priority science goals for decades. Thanks to an innovative design, emerging technology developments and a significant risk reducing engineering development program these critical goals will soon be achieved. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, is designing and building the Solar Pr ...
