Solar Orbiter: The US-European mission to explore the sun's poles in photos
The European Space Agency's Solar Orbiter, a spacecraft designed to observe the sun in incredible, scorching detail, launched to our star on Feb. 9, 2020, on a mission to try and solve some solar mysteries.
The spacecraft will launch atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Air Force Station in Florida at 11:03 p.m. EST (0403 GMT on Feb. 10).
Full story: Solar Orbiter launches on historic mission to study the sun's poles
This is the mission patch for Solar Orbiter.
The $1.5 billion craft, which is a joint collaborative venture between NASA and the European Space Agency (ESA), will give scientists the first-ever good look at our sun's poles.

Scientists hope that these new observations will allow them to solve some long standing mysteries about the sun. The 3,970-lb. (1,800 kg) spacecraft will fly by Venus and Earth several times to swing into a unique orbit around the sun to make these observations.

Solar Orbiter has a suite of ten science instruments that will study the sun. The in situ instruments measure the conditions around the spacecraft itself. The remote-sensing instruments measure what is happening at large distances away.
The Solar Orbiter spacecraft will separate from the launcher around 53 minutes after launch, followed by acquisition of spacecraft signal. In the days after launch, the instrument boom and antennas will be deployed.
During the initial cruise phase, which lasts until November 2021, Solar Orbiter will perform two gravity-assist maneuvers around Venus and one around Earth to alter the spacecraft's trajectory, guiding it towards the innermost regions of the solar system. The first close solar pass will take place in 2022 at around a third of Earth's distance from the sun.
