Nonlinear Interaction of a 3D Kinetic Alfv\ en Wave with a Null Point and Turbulence Generation in the Solar Corona

In the present paper, we have studied nonlinear kinetic Alfv\ en waves (KAWs) in the vicinity of a null point. We have considered the nonlinearity due to ponderomotive effects associated with KAWs in the solar corona. A 3D model equation representing the dynamics of KAWs is developed in this null point scenario. Using numerical methods, we have solved the model equation for solar coronal parameters. The pseudospectral method and the finite difference method have been applied to tackle spatial integration and temporal evaluat ...

The active region source of a type III radio storm observed by Parker Solar Probe during encounter 2

Context. We investigated the source of a type III radio burst storm during encounter 2 of NASA s Parker Solar Probe (PSP) mission.
Aims: It was observed that in encounter 2 of NASA s PSP mission there was a large amount of radio activity and, in particular, a noise storm of frequent, small type III bursts from 31 March to 6 April 2019. Our aim is to investigate the source of these small and frequent bursts.
Methods: In order to do this, we analysed data from the Hinode EUV Imaging Spectrometer, PSP FIELDS, and ...

The radio frequency telecommunications system for the NASA Europa clipper mission

The NASA Europa Clipper mission, a partnership between the California Institute of Technology Jet Propulsion Laboratory (JPL) and the Johns Hopkins University Applied Physics Laboratory (APL), is currently in Phase B and scheduled for launch in 2022. A Jupiter orbiter, it will perform repeated flybys of the moon, Europa, to assess the icy moon’s structure and habitability. The spacecraft’s dual X/Ka-band radio frequency telecommunications subsystem has five primary functions: Provide spacecraft command capability ...

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 ...

Antenna scattering measurements using a scaled 3-D printed spacecraft model

A method to measure an antenna s performance when mounted to an electrically large and complex-shaped spacecraft is described. In the past, either time-intensive numerical simulations or antenna range measurements of an expensive full-scale model of the spacecraft were used to determine the antenna s performance. An alternative method fabricated a reduced-size scaled spacecraft model using 3-D printing processes. The antenna is also reduced in size by the same scale factor as the spacecraft, but the frequency of operation is ...
