Parker solar probe mission design

A mission to the sun originally called Solar Probe was first considered in 1958 and stayed in concept and feasibility studies for five decades until 2007, when a new mission design was created that changed the original mission architecture. The re-designed mission was named Solar Probe Plus due to significant advantages in technical implementation and science return, and it was renamed Parker Solar Probe (PSP) in 2017. PSP was launched on August 12, 2018 as the first mission to touch the Sun. This paper presents an overview ...

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 ...

Flight software verification methods in frontier radio for solar probe plus mission

Success of deep space missions requires comprehensive performance verification for all hardware and software systems on the spacecraft over a broad scope of conditions and configurations, including the telecommunications subsystem. NASA Solar Probe Plus mission uses a software-defined radio for its telecommunications; thus a dedicated suite of tests are required for verification of the radio software in addition to traditional hardware verification procedures. Frontier Radio, developed by Johns Hopkins University Applied Phy ...

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 ...

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 ...

Enabling coherent Ka-band downlink with a software-defined radio

The migration to Ka-band for science downlink on deep space missions increases data rates significantly, but also presents new challenges to radio and RF system designers. One challenge is to maintain low carrier phase noise on a coherent downlink. Thermal noise on the X-band uplink that is within the bandwidth of the carrier recovery process modulates the phase of the coherent downlink. For missions that use X-band for command uplink and Ka-band for science downlink, such as the NASA Solar Probe Plus mission, the ratio of d ...

The Frontier software-defined radio for the solar probe plus mission

The latest adaptation of the Frontier Radio, an X/Ka-band deep space implementation, has been transitioned into a finished product for Solar Probe Plus (SPP) and future missions. Leveraging the technology readiness level (TRL) 9 software-defined radio (SDR) platform successfully flown on the Van Allen Probes (VAP) mission, the Frontier Radio now brings a low-power, low-mass, yet highly radiation-tolerant and robust SDR to deep space applications. This implementation brings with it a suite of enhanced capabilities and improve ...

A theoretical analysis of Ka-band turnaround noise in radios used for deep space comm/Nav

Deep-space missions typically use a radio link between the Deep Space Network (DSN) ground stations and the spacecraft to transmit telemetry data and to generate the range and Doppler shift measurements that enable precise navigation. The amount of carrier phase noise present in this radio link is an important metric of performance, and radios are often designed to minimize the impact of this noise. From a communication perspective, more noise causes an increase in the system s frame-error rate, and from a navigation perspec ...

Optimization of deep-space Ka-band link schedules

Downlink scheduling methods that minimize either contact time or data latency are described. For deep-space missions these two methods yield very different schedules. Optimal scheduling algorithms are straightforward for ideal mission scenarios. In practice, additional schedule requirements preclude a tractable optimal algorithm. In lieu of an optimal solution, an iterative sub-optimal algorithm is described. These methods are motivated in part by a need to balance mission risk, which increases with data latency, and mission ...

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 ...

A review of the Solar Probe Plus dust protection approach

The Solar Probe Plus (SPP) spacecraft will go closer to the Sun than any manmade object has gone before, which has required the development of new thermal and micrometeoroid protection technologies. During the 24 solar orbits of the mission, the spacecraft will encounter a thermal environment that is 50 times more severe than any previous spacecraft. It will also travel through a dust environment previously unexplored, and be subject to particle hypervelocity impacts (HVI) at velocities much larger than anything previously e ...

Hyper velocity protection developments on the solar probe plus mission

The Solar Probe Plus (SPP) spacecraft will go closer to the Sun than any manmade object has gone before. The mission includes both solar flux and micrometeoroid environments much more severe than anything experienced by previous spacecraft. As a result, new analytical and testing methodologies are being developed to ensure the success of the mission. One of the major efforts is the development of an analytical approach for hypervelocity impacts (HVI) at speeds up to 300 km/s. To date, this dust study has made several notable ...
