Execution of Parker solar probe s unprecedented flight to the sun and early results

Parker Solar Probe (PSP) was launched on August 12, 2018, on its way to enter the solar corona and "touch" the Sun for the first time. We utilize enormous planetary gravity assists from 7 repeated Venus flybys via a V7GA trajectory in 24 solar orbits over 7 years, to get within 8.86 solar radii from the Sun s surface. The probe successfully entered the V7GA trajectory and made the first Venus flyby only 52 days after launch. Five weeks later it flew by the Sun at a perihelion distance of 0.166 AU and fl ...

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 ...

Solar Radiation Disturbance Torque Reduction for the Parker Solar Probe Observatory

This paper examines the methodology used for reducing solar pressure disturbance torques for the Parker Solar Probe (PSP) Observatory by minimizing the offset between spacecraft s Center of Gravity (CG) and Center of Pressure (CP). The force due to solar radiation pressures encountered by the PSP spacecraft, particularly at the 9.86 solar-radii (Rs) closest approach point in the orbit, are of a sufficient magnitude to produce significant disturbance torques. Inside of 0.25 AU, the Observatory is required to keep its Thermal ...

Design, fabrication, test, launch, and early operation of the parker solar probe propulsion system

The Parker Solar Probe (PSP) spacecraft, part of NASA’s Living With a Star program, launched on 12 August 2018, atop a Delta IV Heavy launch vehicle with a STAR-48BV upper stage. As NASA’s mission to "touch the Sun," Parker Solar Probe will fly within 3.83 million miles of the Sun and will spend its lifetime studying the gaseous envelope surrounding it: the corona. Over the seven-year mission, PSP will orbit the Sun 24 times and utilize seven Venus fly-bys to gradually shrink its orbit around the Sun. The spacecr ...

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 ...

An integrated quad-band RF front end for high-reliability small satellite missions

As ever-increasing demand for lower size, weight, and power (SWaP) and small satellite platforms continues, it drives development in all sectors, including high-reliability and deep-space technologies. In order to meet these demands, JHU/APL is working to evolve its flight-proven, low-SWaP Frontier Radio (FR) [1] system into even smaller, more efficient, and yet more powerful designs. The Frontier Radio has already successfully flown an S-band version on NASA s Van Allen Probes (VAP) mission, and an X/Ka-band version will la ...

Thermal design verification testing of the solar array cooling system for Parker solar probe

Parker Solar Probe (PSP) will explore the inner region of the heliosphere through in situ and remote sensing observations of the magnetic field, plasma, and accelerated particles. PSP will travel closer to the sun (9.86 solar radii [(RS)]) than any previous spacecraft in order to obtain repeated coronal magnetic field and plasma measurements in the region of the sun that generates the solar wind. The baseline mission will entail 7 years from launch in 2018 until the completion of the 24th orbit; if delays necessit ...

Stray light analysis and testing of the SoloHI (solar orbiter heliospheric imager) and WISPR (wide field imager for solar probe) heliospheric imagers

The techniques for stray light analysis, optimization and testing are described for two space telescopes that observe the solar corona: the Solar Orbiter Heliospheric Imager (SoloHI) that will fly on the ESA Solar Orbiter (SolO), and the Wide Field Imager for Solar Probe (WISPR) that will fly on the NASA Parker Solar Probe (PSP) mission. Imaging the solar corona is challenging, because the corona is six orders of magnitude dimmer than the Sun surface at the limb, and the coronal brightness continues to decrease to ten orders ...

Full wing qualification testing and incremental program update for the solar probe plus array

As the Solar Probe Plus (SPP) program moves into the flight hardware build phase, the final testing of the qualification panel has been completed. The rigorous testing is many orders of magnitude more intensive than that used for standard earth-orbit missions. Testing under high irradiance, high temperature conditions over large areas poses design and logistic challenges, which have spurred innovation in steady state illumination. New test hardware of interest include a large area LED simulator capable of 6X AM0 string curre ...

Capabilities and performance of the high-energy energetic-particles instrument for the parker solar probe mission

NASA s Parker Solar Probe (PSP) spacecraft (formerly Solar Probe Plus) is scheduled for launch in July 2018 with a planned heliocentric orbit that will carry it on a series of close passes by the Sun with perihelion distances that eventually will get below 10 solar radii. Among other in-situ and imaging sensors, the PSP payload includes the two-instrument "Integrated Science Investigation of the Sun" suite, which will make coordinated measurements of energetic ions and electrons. The high-energy instrument (EPI-Hi), operatin ...

Interplanetary dust particle shielding capability of blanketed spacecraft honeycomb structure

To assure mission success of the Solar Probe Plus (SPP) spacecraft, defined by achieving its final mission orbit with a perihelion distance of less than 10 solar radii, it is necessary to define the dust hypervelocity impact (HVI) protection levels provided by its Multi-Layer Insulation (MLI)/thermal blankets with a reliability that is on par with that available for metallic Whipple shields. Recently, we presented an experimentally validated approach being developed at the Johns Hopkins University Applied Physics Laboratory ...

Application of aerogravity assist with active cooling and thermal propulsion to the solar probe mission

Aerogravity assist is an orbital transfer technique that enhances the effect of gravity assist maneuvers by utilizing aerodynamic lift in addition to gravity. This enables greater turning angles from a planetary assist, potentially cutting years off a conventional gravity assisted trajectory with multiple flybys or significantly reducing required launch C3. One of the major challenges are the extreme heat loads and heat fluxes present when flying through atmospheres at interplanetary speeds. Incorporating an activ ...

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 ...

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 RS from the Sun. During those passes, it will encounter a solar flux of ~500 suns, or 70 W/cm2. This flux is more than 50 times larger than the solar heating seen by any previous spacecraft. During the entire mission, the spacecraft and science instruments will be protected by a Thermal Protection System (TPS) ...
