More and more satellites are being added to the lowest Earth’s orbit every month. As this number is increasing, the risks of the important area around the Earth become irrelevant, which implicate us on the planet for the future. The ideas of various laboratories have presented possible solutions to this problem, but one of the most promising, Electrodynamic teathers (EDT), now only testing has started to be tested in space. Called a new cubesat Spacecraft for Advanced Research and Cooperative Studies (Sparks) mission from researchers Sharif University of Technology Testing an EDT and intersatellite communication system in Tehran is expected to contribute to that attempt as well as to collect real-time data on the radiation environment of your orbital path.
Sparcs are actually two different cubsats. SPARCS-A is one 1U cubsat It is mainly designed as a communication platform, with a mission design it requires sparcs-B, which is a 2U cubesat, which, in addition to the communication system, is an EDT. He is deployed through EDT, which can measure in length up to 12 meters, in which a camera is deployed to ensure proper deployment to see.
EDT is essentially huge poles, through which electric current is running. They use this current, and this small magnetic field that produces it, to push the Earth’s natural magnetic field using a property called lorentz force. This allows the satellite to adjust its orbit without the use of fuel, simply oriented its EDT in a specific direction (which can help with the EDT itself) and then using the lorentz force either to push it into a higher orbit, or – more important for objectives for technology performance – to slow down at a point where it can slow down.
Why are EDT important for satellites?
The specialty of that controlled-entry is that EDT has attracted so much attention. Previous missions, such as Kite From Jaxa and Miti From the University of Michigan, already tried to use EDT to change its classes. Unfortunately none of those missions successfully used their EDT, although a follow-up mission called mitee-2 works with a larger EDT compared to Sparcs.
The last piece of sparcs kit is its dosimator, which aims to monitor the radiation environment of its orbit. As anyone knows familiar with the spacecraft design, the radiation of electronics is absolutely important for the success of a mission, but it is also expensive and time taking, so it is best done at the minimum required level. Understanding the radiation environment of this popular orbital tract can help improve future engineers, and is expected to make the design decision according to operation in this specific area.
Engineers have already finalized the design for the mission and have run simulations showing its expected operations. They have now proceeded to manufacture an engineering model of two cubesats, allowing them to validate their design and test the real world implementation before getting ready for launch. Given the current turmoil in that region of the world, there is a chance that the conflict can stop the development of this system. However, if successfully tested and launched, the first performance of an EDT system can be deployed in a very distant future.
