European Space Agency (ESA) Historical Proba -3 Missiondesigned to Study and study solar eclipses in the classroomIs Successfully received his first artificial reception in spaceAnd images are breathtaking.
The Prob -3 mission consists of two satellites that are expertly engineer to operate as a single spacecraft, which ever using the onboard positioning technique unlike anything sent to space, as the lead Proba -3 engineer Steven Bakle of Onsemy, as Steven Bakle. Explained Petpixel Last year. Bakle worked on the project for seven years, ensuring that the sensor and algorithm can align prob -3’s coronographs and Occulter spacecraft with millimeters -level accuracy while traveling at a speed of 22,000 mph.
All that work has paid a large scale, as the Prob -3 team successfully produced artificial solar eclipse for the first time in class. The resulting photos provide major insights and scientific data that will help people gain a deeper understanding of the Sun and its atmosphere.
For solar eclipse scientists on Earth, the sun’s corona is an important opportunity to study its external environment, which helps improve the understanding of coronal mass ejections (CME) that run the space season and have important implications for life on earth. While helping to make cmes Beautiful andorusThey can also disrupt significant communication technologies on Earth.
To create an artificial solar eclipse, the ocular of prob -3 is properly deployed between the Sun and the Korongraph spacecraft. Separated from about 150 meters (about 490 ft), the pair of spacecraft align for six hours within a millimeter of perfection, ensuring that the oocular coronographs completely cover the sun for spacecraft and its imaging devices.
Prob -3 Koronograph has an optical instrument, Association of Spacecraft for Polymetric and Imaging Investigation of the Corona of the Sun (Aspicics) that captures the pictures of solar corona, which appear to be completely blocked, there is a lot of during the Sun. Natural total solar eclipse on earth,
“Many technologies that have allowed Prob -3 to allow accurate formation, flying through ESA’s general support technology program has been developed, as is a mission. It is exciting to see that these stunning images validate our technologies to our technologies that the world’s first accurate is now the world’s first flying mission,” ESA Technology, “Dighty Pills, Engineering, Engineering, Engineering, Engineering, Engineering, Engineering. And the quality directors say.
‘This image shows observation in the coronal green line – a spectral line emitted by iron atoms that lose half of their electrons due to extremely high temperature. This allows us to see the hottest material of Corona up to 2 million degrees. On the upper left, a warm loop can be seen spreading from the surface of the sun to corona, a structure that usually appears after a solar flare. ,

Aspiics did a remarkable job to capture Solar Corona. Along with many people coming in the form of Prob -3, these paintings produce additional artificial eclipses in the orbit, will help scientists to untangle some of the biggest mysteries of the Sun, including its fierce corona, which reaches temperatures above one million ° C, is much warm than the sun’s surface.
Not only can prob-3 to accept on will-some scientists can certainly do not do on Earth-the imagener avoids the issue of unexpected weather and atmospheric deformities. Aspiics can see in incredible detail and detect unconscious solar features compared to other coronographs.
The prob -3 project scientist who says of Xander, “The first data from aspicics is incredibly exciting. With the measurements made by another tool on the board, Dara, Espix will contribute to highlighting long -lasting questions about our home star.”
Dara, which is digital absolute radiometer, measures solar radiation, or the amount of energy originates at a specific time. Prob -3, a third instrument on the 3D energetic electron spectrometer (3 Dase), detects electrons in the Earth’s radiation belt.
“I was absolutely thrilled to see the images, especially since we received him in the first attempt,” says Andrei Zukov, the leading investigator of the aspicics at the Royal Observatory of Belgium. “Now we are working to increase the observation time in every class by six hours.”
“Each full image – from the Sun to the area of the area to the area of the region – is actually built of three images. The difference between them is only the exposure time, which determines how long the aperture of the Korongraph is exposed to light. The combination of three images gives us a full view of corona,” Jhukovi continues.
The scientist says that the “artificial eclipse” picture “is comparable with those taken during a natural eclipse.” However, the difference is that the prob -3 mission makes an eclipse every 19.6 hours, while the total solar eclipse occurs once or rarely on Earth, twice a year. In addition, the totality during a natural eclipse lasts for a few minutes, while Prob -3 can maintain its artificial eclipse for six hours.
The Proba -3 mission manager Demian Galano says, “Being a huge corongraph as two spacecraft in space allowed us to catch internal corona in our comments with a very low level of stray light.”
“Although we are still in the commissioning phase, we have already gained accurate formation to fly with unprecedented accuracy. This is what allows us to capture the first images of the mission, which will not doubt a high value for the scientific community.”
