![]() ![]() These measurements will allow for a comprehensive study of minor ion species in the solar wind allowing for characterization of the origin of the solar wind and parameterization of the corona, along with solar wind evolution. Scientific objectives and instrumentation. The probe will remain several days in the same solar wind stream, to observe its evolution and correlate it with the structures observed on the surface of the Sun. HIS will measure the composition and kinetic properties of heavy ions (He, C, O, Ne, Mg, Si, and Fe – for a variety of charge states) in the solar wind, as well as the composition and velocity distribution functions of major heavy ion constituents in the suprathermal energy range (up to ~100 keV/q). Solar Orbiter’s orbits will be in near-corotation with the Sun. The Heavy Ion Sensor (HIS), part of the Solar Wind plasma Analyzer (SWA) instrument suite on Solar Orbiter, is currently in development at SwRI. Additionally, over the course of the mission, Solar Orbiter will increase its inclination to the solar equator over time, through the use of gravity assists from Venus, and reach an inclination of 34°. The orbit of Solar Orbiter – between 0.9 AU at aphelion and 0.28 AU at perihelion – will allow for a comprehensive study of solar wind evolution. Solar Orbiter is scheduled to launch in 2017 with a primary mission duration of 7 years. Howard, US Naval Research Laboratory, Washington, D.C.Solar Orbiter, the first probe in the joint ESA-NASA HELiophysical EXplorers (HELEX) program, aims to better our understanding of the solar atmosphere and the dynamic solar wind. It is made up of 25 individual images and contains over 83 million pixels. SoloHI: Heliospheric Imager – PI: Russell A. Published The Solar Orbiter has captured the highest-resolution image of the Sun yet. A giant that provides light, warmth and nourishment to. RPW: Radio and Plasma Waves– PI: Milan Maksimovic, LESIA, Observatoire de Paris, France There is a beautiful and terrifying giant that lives in space, 150 million kilometers from Earth. PHI: Polarimetric and Helioseismic Imager – PI: Sami Solanki, Max-Planck-Institut für Sonnensystemforschung, Germany There is a 4.4 meter instrument boom and three 6.5 meter antennas protruding from the spacecraft body. Metis: Coronagraph – PI: Marco Romoli, INAF – University of Florence, Italy Solar Orbiter comprises a 2.5 x 3.0 x 2.5 meter box-shaped bus with two solar panel wings spanning 18 meters to supply power. Solar Orbiter's two 20-foot-long (6 meters) solar arrays tilt with the distance from the sun in order to keep their temperature below 570 degrees F (300 degrees C). MAG: Magnetometer– PI: Tim Horbury, Imperial College London, United Kingdom Its distance from the Sun varies from within the orbit of Mercury to close to the orbit of EarthĮPD: Energetic Particle Detector – PI: Javier Rodríguez-Pacheco, University of Alcalá, SpainĮUI: Extreme Ultraviolet Imager – PI: Pierre Rochus, Centre Spatial de Liège, Belgium Launched in February 2020 from Cape Canaveral, a 1.7-tonne spacecraft called the Solar Orbiter aims to get up-close images of the Sun from 42 million kilometres away, while measuring its energetic behaviour in real-time. Flybys: Multiple gravity assists with Venus will increase Solar Orbiter’s inclination out of the plane of the Solar System by 24º (nominal mission) to 33º (extended mission)Ĭlosest approaches: Solar Orbiter will make a close approach of the Sun every six months. ![]()
