The Sun up close
Solar Orbiter is the most complex scientific laboratory ever sent to our life-giving star, taking images of the Sun from closer than any spacecraft before and being the first to look at its polar regions. With Solar Orbiter's ten instruments, scientists hope to answer some profound questions: What drives the Sun’s 11-year cycle of rising and subsiding magnetic activity? What heats up the upper layer of its atmosphere, the corona, to millions of degrees Celsius? How does solar wind form, and what accelerates it to speeds of hundreds of kilometres per second? And how does it all affect our planet?
- Launch date: February 2020
- First images: July 2020
- Beginning of routine science operations: November 2021
- Mission highlights: The closest-ever images of the Sun, the first ever close-up images of the Sun’s polar regions, measuring the composition of the solar wind and linking it to its area of origin on the Sun’s surface
- Closest distance to the Sun: 42 million kilometres
