No satellite remains the same after launching into space. However, much it transforms could go unobserved until something terrible ensues.
Carolin Frueh is one of the many researchers who have persevered in using a composite technique that can identify a problem from miles away based on the way the satellite mirrors sunlight.
Carolin Frueh, who is an assistant professor at Purdue University in the school of Aeronautics and Astronautics, stated that one couldn’t get out of a moving car to check if something has fallen or scratched. However, you realize there might be a problem. She added that an operator might observe that a satellite is wobbly or having charging issues. An outside viewpoint can notify if it is as a result of breakage or an antenna or panel is improperly oriented.
Failing to diagnose the issue increases the losing chances or not being able to reinstate communication with the satellite. After the connection is lost, a spacecraft might reduce into pieces of debris that remain in the space for thousands of years or forever unless they are actively removed from scope.
According to a Strategic Command database of the United States of America, the ‘space junk’ is dangerous to other rockets, and there are about 100,000 pieces of debris more significant than a penny in the Earth’s orbit.
Space is made of a vacuum that directly affects a satellite. Regular transitions between the deep Earth’s shadow cold and the severe heat coming from the sun also takes part over time.
Carolin Frueh stated that every bit about a satellite is known when it is on the ground, however the arrangement changes due to it being carried up; some parts require to be folded. After launching into space, panels are unfolded, firmly oriented on the direction of the sun, and the antenna is then pointed towards the Earth. So this means that the longer the satellite stays in the space, the less we know about its situation.
Satellites are approximately illuminated always by the sun, apart from little transitions to the shadow of the Earth. The light reflected by a moon could assist in revealing the solution to a structural failure.
The method requires the use of telescopes on Earth to collect the reflected light from the satellite. Since satellites are miles away, the bits and pieces might merely appear like white dots on the telescope image, dots that are similar to the night stars.
