![]() Howard, US Naval Research Laboratory, Washington, D.C. As if trying to get the orbiter’s attention as it cosied up to another body in the Solar System, the Sun flung an enormous coronal mass ejection. SoloHI: Heliospheric Imager – PI: Russell A. 5 September 2022 In the early hours of Sunday, 4 September, Solar Orbiter flew by Venus for a gravity-assist manoeuvre that alters the spacecraft’s orbit, getting it even closer to the Sun. RPW: Radio and Plasma Waves– PI: Milan Maksimovic, LESIA, Observatoire de Paris, France Since planets in the Solar System are in nearly circular orbits their individual orbital velocities do not vary much. PHI: Polarimetric and Helioseismic Imager – PI: Sami Solanki, Max-Planck-Institut für Sonnensystemforschung, Germany The Solar Orbiter minimum perihelion of 0.28 AU, combined with the unique out-of-ecliptic viewing, Solar Orbiter will address a fundamental question of solar physics: How does the Sun. Metis: Coronagraph – PI: Marco Romoli, INAF – University of Florence, Italy 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 passage of corotating high-speed solar wind streams (HSSs) may also produce. ![]() 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. The spacecraft will launch in August 2022 and travel about 1.5 billion miles (2.4 billion kilometers) over three and a half years to get to the asteroid, which scientists believe may be part of the core of a planetesimal, the building block of an early rocky planet. obtained by the Solar Orbiter (SolO) and Parker Solar Probe (PSP) pioneering. ![]()
