Space scrap threatens satellites: new megahertz laser in use!

A groundbreaking progress in space research could significantly improve security in the earth orbit. Researchers from the Institute for Space Research (IMF) of the Austrian Academy of Sciences (ÖAW) have developed a megahertz laser that enables high-precision measurements to satellites and space. Currently around 10,000 functional satellites circle the earth, while almost 40,000 objects made of space scrap, larger than ten centimeters, represent a potential danger, as reports.

The new laser, which can carry out up to 1,000,000 measurements per second, significantly improves the accuracy of the distance measurements. With this technology, the researchers were able to record up to two million precise data points in a short time, which reduces normal point accuracy to a few micrometers. Michael Steindorfer, one of the project managers, emphasizes that this system enables the simultaneous measurement of satellites and space scrap without adjustments to the measurement structure, which can contribute significantly to avoid collisions. This innovation is also presented in the specialist magazine "Nature Communications", such as APA Science Notes.

The technology is based on a sophisticated approach, in which a laser with different pulse duration is used for satellites and space scrap. While satellites are measured with special rear -reflecting elements, the higher measured values in space scrap do not give any millimeter -precise results due to its diffuse reflection. The new megahertz laser overcomes this restriction and combines the advantages of both measurement methods, which could revolutionize research to endanger the danger from space scrap. With these tailor -made systems, the existing 40 laser stations could be used more efficiently in the monitoring of the area close to the earth without constant cumbersome system adjustments.
