The first images from ESA’s new Sun-observing spacecraft Solar Orbiter will be released to the public on 16 July 2020. Media representatives are invited to watch an online press briefing, which will take place at 14:00 CEST (13:00 BST), and talk to the scientists behind the mission.
Solar Orbiter, launched on 10 February, completed its commissioning phase in mid-June and performed its first close approach to the Sun. Shortly thereafter, the European and US science teams behind the mission’s 10 instruments were able to test the entire instrument suite in concert for the first time.
- Better than expected
Despite the setbacks the teams faced while commissioning the spacecraft and its instruments amid the COVID-19 pandemic, the first imaging campaign has been a great success.
“The first images are exceeding our expectations,” says Daniel Müller, Solar Orbiter Project Scientist at ESA. “We can already see hints of very interesting phenomena that we have not been able to observe in detail before. The 10 instruments on board Solar Orbiter work beautifully, and together provide a holistic view of the Sun and the solar wind. This makes us confident that Solar Orbiter will help us answer profound open questions about the Sun.”
- We have never been closer with a camera
No other images of the Sun have been taken from such a close distance. During its first perihelion, the point in the spacecraft’s elliptical orbit closest to the Sun, Solar Orbiter got as close as 77 million kilometres from the star’s surface, about half the distance between the Sun and Earth. The spacecraft will eventually make much closer approaches to the Sun. The spacecraft is now in its cruise phase, gradually adjusting its orbit around the Sun. Once in its science phase, which will commence in late 2021, the spacecraft will get as close as 42 million kilometres from the Sun’s surface, closer than the planet Mercury. The spacecraft’s operators will gradually tilt Solar Orbiter’s orbit to enable the probe to get the first proper view of the Sun’s poles.
- An international mission
Solar Orbiter is a space mission of international collaboration between ESA and NASA. Twelve ESA Member States (Austria, Belgium, the Czech Republic, France, Germany, Italy, Norway, Poland, Spain, Sweden, Switzerland, and the United Kingdom) as well as NASA contributed to the science payload. Denmark, Finland, Ireland, Luxembourg, the Netherlands and Portugal contributed to building the spacecraft but not to the science payload.

The European Space Agency (ESA) provides Europe’s gateway to space.
ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.
ESA has 22 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Slovenia is an Associate Member.
ESA has established formal cooperation with seven Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.
By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.
ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities.
Today, it develops and launches satellites for Earth observation, navigation, telecommunications and astronomy, sends probes to the far reaches of the Solar System and cooperates in the human exploration of space. ESA also has a strong applications programme developing services in Earth observation, navigation and telecommunications.
