Identifying and Mitigating Barriers to the Adoption of Dynamic Radioisotope Power Systems for Space Flight

Given increasing complexity of many safety-critical systems, many organizations like NASA need to identify when, where, and how inappropriate perceptions of risk and anchoring of trust affect technology development and acceptance, primarily from the perspective of engineers and related management. Using the adoption of Dynamic Radioisotope Power Systems (RPS) for space exploration as a backdrop, we define and explain factors that contribute to inappropriate risk perception of various stakeholders. Three case studies (Mars Sc ...

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 ...

Charting a course to the sun: Flight path control for parker solar probe

The successful launch of the Parker Solar Probe (PSP) on August 12, 2018 with a Delta IV rocket and Star-48BV third stage has placed the spacecraft on a 7-year trajectory to study the Sun. The goals of PSP are to better characterize our solar environment and advance our understanding of the Sun at 9.86 Rs. A total of 42 trajectory correction maneuvers are planned. This paper documents trajectory correction maneuver analysis performed just prior to launch until just past the first solar encounter. The pre-launch analysis culm ...

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 ...

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 ...

Initial attitude control challenges for the solar probe plus spacecraft

The Solar Probe Plus (SPP) mission plans to launch a spacecraft to explore the Sun in 2018. Attitude control is maintained with a 3-axis stabilized, closed-loop control system. One of the first tasks for this system is acquiring attitude knowledge and establishing attitude control after separation from the launch vehicle. Once control is established, the spacecraft must be moved through a sequence of attitudes to meet power and thermal constraints and reach a powerpositive state. This paper describes the options selected for ...

Full scale thermal simulator development for the solar probe plus thermal protection system

Solar Probe Plus (SPP) is a NASA mission that will go within ten Solar Radii of the sun. One of the crucial technologies in this system is the Thermal Protection System (TPS), which shields the spacecraft from the sun. The TPS is made up of carbon-foam sandwiched between two carbon-carbon panels, and is approximately eight feet in diameter and 4.5 inches thick. At its closest approach, the front surface of the TPS is expected to reach 1200°C, but the foam will dissipate the heat so the back surface will only be about 300 ...

Navigating an earned value management validation led by NASA: A contractor s perspective and helpful hints

In 2012, The Johns Hopkins Applied Physics Laboratory (APL) was approved by the National Aeronautics and Space Administration (NASA) to move forward with Phase B of the Solar Probe Plus (SPP) Mission to design and build the first spacecraft to fly into the Sun s outer atmosphere and study its effects on planetary systems and human activities. While APL had successfully utilized its earned value management system (EVMS) on the Van Allen Probes mission, the SPP contract called for a "certified" EVMS, which required an in-depth ...

The Solar Probe Plus (SPP) mission is the culmination of decades of studies on spacecraft designed to explore the inner region of the heliosphere. The mission is being implemented by the Johns Hopkins University Applied Physics Laboratory for a 2018 launch. Building on the flight experiences of the Helios (NASA/FRG) and MESSENGER (NASA/JHUAPL) spacecraft and several remote studies, SPP will be the closest operating spacecraft to the Sun, even surpassing the 2017 planned launch of the Solar Orbiter (ESA/NASA) spacecraft.

Array-design considerations for the solar probe plus mission

The NASA Solar Probe Plus (SPP) mission will fly into and study the Sun s corona, reaching as close as 8.5 solar radii from the surface of the Sun. Power generation for the spacecraft will be provided by two solar array wings, which are being designed and built by Johns Hopkins University Applied Physics Laboratory and Emcore Photovoltaics. SPP will get closer to the Sun than any previous mission, and the solar array will therefore need to operate reliably under unusually high irradiances, temperatures, and angles of inciden ...

Solar Probe Plus: Impact of light scattering by solar system dust on star tracker performance

NASA s upcoming Solar Probe Plus mission will be the first to approach the Sun as close as 8.5 solar radii from the surface and provide in-situ observations of the Sun s corona. In the absence of observational data (e.g., Helios, Pioneer), for distances less than 0.3 AU, the ambient dust distribution close to the Sun remains poorly known and limited to model extrapolation for distances < 1 AU. For the Solar Probe Plus (SPP) mission it is critical to characterize the inner solar system dust environment to evaluate potential i ...

Combined effect of high temperature and VUV radiation on carbon-based materials

For the next exploration of the sun, missions like Solar Probe+ (NASA) or Phoibos (ESA) will be launched to answer to fundamental questions on the solar corona heating and solar winds origin. Such solar probes missions that will pass very close to the sun, respectively at 9.5 and 4 solar radii (Rs), need thermal shield to protect the payload and the instrumentation. Carbon/carbon composites can withstand the severe environment encountered during the pass of the sun and have to be studied to understand their physico-chemical ...
