Solar Probe Plus will fly to less than 10 solar radii (Rs) of the Sun, having “walked in” from 35 Rs over 24 orbits.

The concept for a “Solar Probe” dates back to “Simpson’s Committee” of the Space Science Board (National Academy of Sciences, 24 October 1958) ‒ The need for extraordinary knowledge of Sun from remote observations, theory, and modeling to answer the questions: – Why is the solar corona so much hotter than the photosphere? – How is the solar wind accelerated? .

  • 1 the New Horizons Spacecraft Glen H. Fountain, David Y
    The New Horizons Spacecraft Glen H. Fountain, David Y. Kusnierkiewicz, Christopher B. Hersman, Timothy S. Herder, Thomas B Coughlin, William T. Gibson, Deborah A. Clancy, Christopher C. DeBoy, T. Adrian Hill, James D. Kinnison, Douglas S. Mehoke, Geffrey K. Ottman, Gabe D. Rogers, S. Alan Stern, James M. Stratton, Steven R. Vernon, Stephen P. Williams Abstract The New Horizons spacecraft was launched on January 19, 2006. The spacecraft was designed to provide a platform for the seven instruments designated by the science team to collect and return data from Pluto in 2015 that would meet the requirements established by the National Aeronautics and Space Administration (NASA) Announcement of Opportunity AO-OSS-01. The design drew on heritage from previous missions developed at The Johns Hopkins University Applied Physics Laboratory (APL) and other NASA missions such as Ulysses. The trajectory design imposed constraints on mass and structural strength to meet the high launch acceleration consistent with meeting the AO requirement of returning data prior to the year 2020. The spacecraft subsystems were designed to meet tight resource allocations (mass and power) yet provide the necessary control and data handling finesse to support data collection and return when the one way light time during the Pluto fly-by is 4.5 hours. Missions to the outer regions of the solar system (where the solar irradiance is 1/1000 of the level near the Earth) require a Radioisotope Thermoelectric Generator (RTG) to supply electrical power. One RTG was available for use by New Horizons. To accommodate this constraint, the spacecraft electronics were designed to operate on less than 200 W.

  • NASA Finds Neptune Moons Locked in 'Dance of Avoidance' 15 November 2019, by Gretchen Mccartney
    NASA finds Neptune moons locked in 'dance of avoidance' 15 November 2019, by Gretchen McCartney Although the dance may appear odd, it keeps the orbits stable, researchers said. "We refer to this repeating pattern as a resonance," said Marina Brozovi?, an expert in solar system dynamics at NASA's Jet Propulsion Laboratory in Pasadena, California, and the lead author of the new paper, which was published Nov. 13 in Icarus. "There are many different types of 'dances' that planets, moons and asteroids can follow, but this one has never been seen before." Far from the pull of the Sun, the giant planets of the Neptune Moon Dance: This animation illustrates how the outer solar system are the dominant sources of odd orbits of Neptune's inner moons Naiad and gravity, and collectively, they boast dozens upon Thalassa enable them to avoid each other as they race dozens of moons. Some of those moons formed around the planet. Credit: NASA alongside their planets and never went anywhere; others were captured later, then locked into orbits dictated by their planets. Some orbit in the opposite direction their planets rotate; others swap orbits Even by the wild standards of the outer solar with each other as if to avoid collision. system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to Neptune has 14 confirmed moons.

    The Coolest, Hottest Mission under the Sun!! Dr. Nicola J. Fox Parker Solar Probe Project Scientist JHU/Applied Physics Laboratory Parker Solar Probe A NASA Mission to Touch the Sun We are PARKER SOLAR PROBE! Parker, meet Parker December 12, 2017 Parker Solar Probe– Fall AGU 2017 Why haven’t we gone to the Sun yet? It took the same technological leap from a rotary phone to an iPhone X for Parker Solar Probe to become a reality December 12, 2017 Parker Solar Probe– Fall AGU 2017 Parker Solar Probe Science . To determine the structure and dynamics of the Sun’s coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what mechanisms accelerate and transport energetic particles. Detailed Science Objectives • Trace the flow of energy that heats and accelerates the solar corona and solar wind. • Determine the structure and dynamics of the plasma and magnetic fields at the sources of the solar wind. • Explore mechanisms that accelerate and transport energetic particles. November 16, 2017 Parker Solar Probe Mission Briefing Modeling: Providing the missing piece . In-situ data from within 0.25 AU will be available Manchester 2014 shortly after each orbit for ingestion into the coronal, solar wind and global heliospheric models . PSP would also benefit invaluably from knowing the mapping between the spacecraft and the solar surface though each orbit . Global simulations of CMEs would provide critical context when we fly through CMEs . Contact [email protected] or [email protected] Baker

    30th Annual Thermal & Fluids Analysis Workshop TFAWS 2019, 26-30 August 2019 Newport News, VA Post-Launch and Early Mission Thermal Performance of Parker Solar Probe through the First Two Solar Orbits TFAWS19-AT-07 Carl J Ercol [email protected] G. Allan Holtzman Parker Solar Probe [email protected] A NASA Mission to Touch the Sun 30th Annual Thermal & Fluids Analysis Workshop 26-30 August 2019, Newport News, VA Parker Solar Probe Mission Summary Overview Using in-situ measurements made closer to the Sun than by any previous spacecraft, Parker Solar Probe (PSP) will determine the mechanisms that produce the fast and slow solar winds, coronal heating, and the transport of energetic particles. PSP will fly to 9.86 solar radii (Rs) of the Sun, having “walked in” from 35.7 Rs over 24 orbits, two of which have been completed to date.
