ESA Science & Technology - Solar Orbiter

Solar Orbiter's latest results show that the mission is making the first direct connections between events at the solar surface and what's happening in interplanetary space around the spacecraft. It is also giving us new insights into solar 'campfires', space weather and disintegrating comets.

ESA has released its first Solar Orbiter data to the scientific community and the wider public. The instruments contributing to this data release come from the suite of in-situ instruments that measure the conditions surrounding the spacecraft.

The first images from Solar Orbiter, a new Sun-observing mission by ESA and NASA, have revealed omnipresent miniature solar flares, dubbed 'campfires', near the surface of our closest star.

ESA's Solar Orbiter has successfully completed four months of painstaking technical verification, known as commissioning. Despite the challenges imposed by the COVID-19 pandemic, the spacecraft is now ready to begin performing science as it continues its cruise towards the Sun.

ESA's Sun-exploring mission Solar Orbiter has made its first close approach to the Sun on 15 June, getting as close as 77 million km to the star's surface, about half the distance between the Sun and Earth.

Watch a replay of the live coverage of the launch of Solar Orbiter, ESA's new Sun-exploring spacecraft, which will look at our parent star from a completely new perspective. The spacecraft was launched by the US Atlas V 411 rocket from NASA's Kennedy Space Centre in Cape Canaveral, Florida, on 10 February 2020.
