According tomedia reports, you may not see the space junk when looking up at the night sky, but now it is true that they are spinning around the earth. Scrap satellite debris, abandoned rocket stages and other man-made debris surround the planet we live on like a giant garbage bubble. Tracking the location of these objects is necessary for the safety of working satellites and for the personnel missions, even for the dangers they pose to the International Space Station.
According to the Massachusetts Institute of Technology Technology Review, a new technique for tracking the debris allows people to spot space junk during the day, rather than in the tiny time window, as it used to be.
Launching a laser into space is a way for scientists to track space debris. When a laser hits an object, it bounces back, and scientists can detect the reaction and record it when it finds the trash. Unfortunately, however, the accuracy of this technique is not very high, and it is difficult to locate an object by laser response alone.
To improve the effectiveness of the laser method, scientists began to look at the sky with lenses designed to detect sunlight reflected by objects. However, this can only be done at dawn or dusk, as daytime light blurs the imaging instrument and hinders detection and tracking that should be very easy.
Now, in a new paper published in Nature Communications, researchers say they have devised a new way to track space junk during the day. They built a special imaging system with filters that allowed researchers to see stars in the blue sky.
“Space debris can be visualized against a blue sky background and can correct deviations in real time,” the researchers said of their new system. These results are the starting point for all space debris laser ranging stations to significantly increase their output in the near future. A network of observatories around the world would greatly improve orbital prediction, which is necessary for removal tasks, connection warnings, evading maneuvers, or posture determination. “
Tracking space debris will become increasingly important as humans continue to explore the solar system with probes and even manned missions. While navigating between trash that has been thrown into space can be more challenging, a system like this might make things a little easier.
