NASA's Curiosity rover is working on dual tasks. It is studying rock soil samples on Mars and is also helping scientists to observe and study sunspots on the far side of the sun. The rover has captured the images of the sunspots on that side of the sun that is turned away from earth.

Curiosity has captured images using its mast camera (Mastcam). The images have been sent back on earth that will help scientists to know more about solar emissions. For now, scientists do not have any other way by which they can have a view of the sun that is not facing earth.

Scientists were of the view that sunspots can prove beneficial when it comes to predicting space-weather effects of solar emissions with regard to sunspots. These sunspots that are on the father side will eventually be when the rotation of the sun will get completed.

"One sunspot or cluster that rotated out of Curiosity's view over the July 4 weekend showed up by July 7 as a source area of a solar eruption observed by NASA's Earth-orbiting Solar Dynamics Observatory", said NASA.

Current problem is that when the spacecraft is on the far side of the sun then it does not have communication with earth. Last month, communication with the rover was stopped when Mars passed quite close behind the sun. But the rover was able to resume communication in late June.
