Solar Orbiter speeds towards its next rendezvous with the Sun

The ESA-led Solar Orbiter mission arrives at its next close approach to the Sun on 12 October 2022 at 19:12 UTC (21:12 CEST). This sequence of images shows the progress of the ESA/NASA spacecraft as it heads inwards on its voyage of discovery. The sequence begins on 20 September and finishes on 10 October. The sequence was taken by the Extreme Ultraviolet Imager (EUI) using the Full Sun Imager (FSI) telescope, and shows the Sun at a wavelength of 17 nanometers. This wavelength is emitted by gas in the Sun’s atmosphere with a temperature of around one million degrees. The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye. So much of modern society relies on spacecraft in orbit around Earth to provide essential communications and navigation. Understanding more about the Sun and the ‘space weather’ it generates will help companies operate their satellites around Earth safely and securely. Towards the en
