Solar Orbiter’s Second Venus Flyby

Visualization of ESA’s Solar Orbiter spacecraft flying by Venus on 9 August 2021. The spacecraft will make numerous gravity assist flybys at Venus to bring it closer to the Sun and to tilt its orbit in order to observe our star from different perspectives. Solar Orbiter’s path around the Sun has been chosen to be ‘in resonance’ with Venus, which means that it will return to the planet’s vicinity every few orbits and can again use the planet’s gravity to alter or tilt its orbit. Initially, Solar Orbiter will be confined to the same plane as the planets, but each encounter of Venus will increase its orbital inclination. By 2025 it will make its first solar pass at 17º inclination, increasing to 33º by the end of the decade, bringing even more of the polar regions into direct view. This will result in the spacecraft being able to take the first-ever images of the Sun’s polar regions, cruci
