The Perseverance Rover on Mars has a camera that takes pictures of the Sun. These pictures are helpful because Mars often sees a different side of the Sun than we do from Earth.. We're using this camera to look at sunspots on the Sun's 'far side.' To make sure we understand what the Martian photos are showing us , we first compare them with pictures from a satellite near Earth, called SDO, when both are looking at the same side of the Sun. Once we match up these two sets of images, we can then use the Mars photos to better understand sunspots detected on the far side of the Sun, by a method called Helioseismology (which uses sound waves to “see through” the Sun from Earth, similar to sonar). By understanding sunspot properties between the Perseverance camera and the Helioseismology method, we will eventually be able to figure out those properties from Helioseismology alone (even when Mars isn’t seeing the far side of the Sun). This information will give us a complete view of the Sun, which is vital for better predicting space weather and protecting our technology both in space and on Earth.
