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.

Watch space station’s new solar array unfurl in space
A new solar array unfurling at the space station in December 2022.

Two American astronauts successfully completed a spacewalk at the International Space Station (ISS) on Saturday, December 3.

NASA’s Josh Cassada and Frank Rubio spent just over seven hours outside the orbital laboratory before concluding their spacewalk at 2:21 p.m. ET. This was only the second spacewalk for both astronauts, following the pair’s first one on November 15.

Mars Express orbiter has relayed data from seven different Mars missions
An artist's impression of Mars Express. The spacecraft left Earth for Mars on 2 June 2003. It reached its destination after a six-month journey, and has been investigating the planet since early 2004.

When a rover is exploring the surface of Mars, it doesn't send data straight back to Earth. That's for two reasons: Firstly, it would require a large, powerful antenna which would be cumbersome and expensive to add, and secondly, because of the rotations of Earth and Mars any location on the surface would be pointing in the wrong direction some of the time.

So, to get data back from Mars surface missions, we use a network of Mars orbiters, which collect data from rovers and landers and relay it back to Earth. Known as the Mars Relay Network, these orbiting spacecraft take on relay duties in addition to their scientific roles observing the red planet. Recently, one of these orbiters, the European Space Agency (ESA)'s Mars Express set a new record for relaying data from seven different Mars surface missions.

See the ‘quiet’ of the sun’s corona in Solar Orbiter footage
The ESA-led Solar Orbiter mission has experienced its second close encounter with the Sun. It is delivering more stunning data, and at higher resolution than ever before.

Solar Orbiter, the European Space Agency (ESA) mission that launched in 2020 and which includes the closest camera to the sun, has made a second close approach of our star and has captured stunning footage of the sun's corona.
