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.

NASA’s DART mission successfully changed asteroid’s orbit

The results of NASA’s ambitious DART planetary mission are in, and the results are very good indeed.

In a historic announcement on Tuesday, the space agency confirmed that for the first time, humanity has succeeded in changing the orbit of a planetary body, suggesting we now have a way to protect ourselves against hazardous asteroids spotted coming our way.

See the horror of the sun up close from world’s most powerful solar telescope
The first images of the chromosphere – the area of the Sun’s atmosphere above the surface – taken with the Daniel K. Inouye Solar Telescope on June 3rd, 2022. The image shows a region 82,500 kilometers across at a resolution of 18 km. This image is taken at 486.13 nanometers using the hydrogen-beta line from the Balmer series.

The astronomy community has a new tool for studying the sun, with the inauguration this week of the world's largest solar telescope. The Daniel K. Inouye Solar Telescope, located in Maui, Hawai'i, has a 13-foot (4-meter) primary mirror enabling it to see the sun in phenomenal detail.

To celebrate the telescope's inauguration on August 31, 2022, this week the National Science Foundation (NSF) released a new image of the sun's chromosphere. This is the part of the sun's atmosphere that is right above its surface, and the image shows a region 50,000 miles across where temperatures can be as high as 13,000 degrees Fahrenheit.

Plotting the death of our sun using data from Gaia

Nothing in this world is forever -- not even the sun in the sky. Recent research using data from the European Space Agency's Gaia satellite has shed light on the eventual fate of our sun, which will puff up to become an enormous red giant, likely swallowing the Earth, before eventually dimming to a small, faint white dwarf.
