WISPR

Diagram of WISPR

The Wide-Field Imager for Solar Probe (WISPR) is an imaging instrument of the Parker Solar Probe mission to the Sun, launched in August 2018.[1] Imaging targets include visible light images of the corona, solar wind, shocks, solar ejecta, etc.[1] Development of WISPR was lead by the U.S. Naval Research Laboratory.[2] The Parker Solar Probe with WISPR on board was launched by a Delta IV Heavy on 12 August 2018 from Cape Canaveral, Florida.[3] WISPR is intended take advantage of the spacecraft proximity to the Sun, to take coronograph-style images of the Solar corona and features like coronal streamers, plumes, and mass ejections.[4] One of the goals is to better understand the structure of the Solar corona near the Sun.[5]

WISPR is designed to study the electron density and velocity structure of the corona.[6] The instrument field of view is planned to extend from 13 to 108 degrees away from the Sun, and does not directly image the Sun; the area of interest is a very wide field extending away from the Sun.[1]

WISPR includes two separate telescopes, each with a radiation-hardened CMOS imager with resolution of 2,000×2,000 pixels.[7] The CMOS sensors are an active pixel sensor type of detector.[8]

WISPR first light image was published in September 2018.[9]

On the right side, the it is from one of 2 cameras within WISPR, this one with a 40-degree field of view, and the right edge is 58.5 degrees from the center of Sun according to NASA.[10] The left side has a 58-degree field of view and reaches to160 degrees from the Sun.[11]
