British startup Magdrive is offering a new type of solid-metal propulsion for satellites. Unlike conventional systems, these motors make orbiting much more efficient. CNN reports that such technology could increase the maneuverability of satellites tenfold.
The problem of space debris and the Magdrive solution
The problem of space debris is becoming more and more urgent. Humanity has launched more than 20,000 satellites into orbit, some of which have already burned up in the atmosphere or fallen to Earth. But more than 13,000 satellites are still orbiting, a fifth of which are defunct. This debris poses a threat to active satellites and the International Space Station.
The magnetic technology developed by Magdrive converts metal into a boiling plasma, creating a powerful gravitational effect. As a result, the engine efficiency increases and satellites move faster and more precisely in orbit. Currently, the startup is using copper for the engines, but other alloys will be tested in the future.
Using waste as fuel in the future
The most interesting aspect of Magdrive is that it allows space debris to be used as fuel in the future. Satellites based on this technology can collect metal in orbit and convert it into energy. This will not only reduce space debris, but also make space missions autonomous and self-sufficient.
Orbital cleaning projects
In addition to Magdrive, the European Space Agency and Japan are also working on cleaning space debris. The European Space Agency plans to launch the ClearSpace-1 device in 2026. This device is equipped with four robotic manipulators to collect large debris. Japanese engineers have created a wooden satellite called LignoSat, which burns up completely when it enters the atmosphere.
Problems and legal issues
There are some problems with the technology of using metal as a fuel. For example, metal particles can settle on the satellite panels, reducing their efficiency. There are also legal issues - according to international agreements, even a decommissioned satellite belongs to its owner. This complicates the process of their recycling.
Magdrive's new magnetic engines and waste recycling idea could revolutionize space exploration. If this technology is implemented, space debris could become not only a problem, but also a valuable resource. Therefore, the idea of using metal fuel for satellites in the future may have great prospects.
