The experimental “Marathon” for the Internet of Things will go into orbit in the first quarter
According to JSC «Reshetnev» (part of Roscosmos), the Marathon spacecraft, which is produced at the enterprise, uses antenna-feeder devices printed with metal on a 3D printer. Experimental satellite «Marathon» is being created within the framework of the federal project «Sfera», on the basis of such spacecraft it is planned to implement Internet of Things services. «Marathon» will be the first Russian satellite in orbit to use 3D printed elements.
At the complex for selective laser melting of metal powders for the first flight vehicle «Marathon» 16 emitter screens and 4 feeder line antennas were created. In addition, a set of products for autonomous testing was designed and manufactured, consisting of 10 antennas and 15 brackets for flywheel motors; all these elements passed the test successfully. Using additive technologies, it is planned in the future to produce elements for serial satellites «Marathon».
Experimental satellite «Marathon» should go into space as a passing payload along with the hydrometeorological satellite «Meteor-M» No. 2-4, launched by the launch vehicle «Soyuz-2.1b» scheduled for the first quarter of 2024.
