Solar Orbiter blasts off on mission to discover the secrets of the sun

The Solar Orbiter is on its way to the sun. The spacecraft got off to a perfect start late Sunday night, with a flawless launch aboard an Atlas V 411 rocket from Cape Canaveral, Florida, at 11.03 p.m. ET.

The ambitious mission, jointly operated by the European Space Agency (ESA) and NASA, should give us the best view yet of our star, including the first proper look at its uncharted polar regions.

Shortly after the Atlas rocket delivered the Solar Orbiter to space, ESA was able to confirm that the spacecraft’s all-important solar array had properly deployed, supplying it with power.

The $672 million Solar Orbiter, which is kitted out with a suite of highly sensitive instruments for imaging the surface of the sun and measuring the properties of the nearby environment, will take almost two years to reach its initial operational orbit in a mission that could last up to a decade.

“As humans, we have always been familiar with the importance of the sun to life on Earth, observing it and investigating how it works in detail, but we have also long known it has the potential to disrupt everyday life should we be in the firing line of a powerful solar storm,” said Günther Hasinger, ESA Director of Science. “By the end of our Solar Orbiter mission, we will know more about the hidden force responsible for the sun’s changing behavior and its influence on our home planet than ever before.”

Thomas Zurbuchen, NASA’s associate administrator for Science at the agency’s headquarters in Washington DC, promised the Solar Orbiter would do “amazing things” during its mission. “Combined with the other recently launched NASA missions to study the sun, we are gaining unprecedented new knowledge about our star,” Zurbuchen said. He added that data from the mission will also help make astronauts safer as they travel on upcoming Artemis missions to the moon and beyond.

Remarkable imagery shows NASA probe as it’s hit by a solar storm
A mid-level solar flare that peaked at 8:13 p.m. EDT on Oct. 1, 2015, captured by NASA’s Solar Dynamics Observatory.

A NASA spacecraft captured incredible imagery as it flew through an eruption from the sun recently. Pictures beamed back to scientists on Earth even show the fiery ejection "vacuuming up" space dust left over from the formation of the solar system.

The fly-through by NASA’s Parker Solar Probe took place on September 5 and NASA shared the imagery (below) on Monday.

Solar Orbiter and Parker Solar Probe work together on a puzzle about our sun

One of the biggest puzzles about our sun is a strange one: you might think that it would be hottest right at the surface, but in fact, that isn't the case. The corona, or the sun's outer atmosphere, is hundreds of times hotter than its surface. It's still not clear exactly what that should be the case, so it's an issue that solar missions are keen to research.

Scientists ‘hack’ Solar Orbiter’s camera to get a better look at the sun
Scientists have used the ESA/NASA Solar Orbiter’s Extreme Ultraviolet Imager (EUI) in a new mode of operation to record part of the Sun’s atmosphere that has been almost impossible to image until now. By covering the Sun’s bright disc with an ‘occulter’ inside the instrument, EUI can detect the million-times fainter ultraviolet light coming from the surrounding corona.

The European Space Agency's (ESA) Solar Orbiter spacecraft is performing a long series of flybys of various planets to bring it closer and closer to the sun on each pass. It will eventually come within 26 million miles to observe the sun up close, and enter in the orbit of Mercury. It will be the closet a camera has ever gotten to the sun, in order to take detailed images of the sun's corona and its local environment.
