The two satellites are: a "service satellite", weighing 175 kg (main satellite, left part of the figure above); a "customer satellite", weighing 17 kg (sub module, right part of the figure above) Section). The - main satellite , equipped with proximity rendezvous technology and magnetic docking device, is equipped with a magnet docking plate on the - sub module , which is mainly used to absorb space garbage and dock with - main satellite . Once the two parts are separated, they will play a cat and mouse game in the next six months. The elsa-d mission will use the satellite's magnet docking plate to complete the space garbage collection work. < / P > < p > Seita Iizuka, project director of elsa-d, said: "it is gratifying that it has been confirmed that the astroscale mission operation team has successfully contacted the elsa-d satellite and all initial system checks are satisfactory. We are looking forward to the first phase of the technical demonstration." < / P > < p > through a series of exercises, the satellite has the ability to capture space debris and bring it back to earth < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%A4%A7%E6%B0%94%E5%B1%82 "> the ability of the atmosphere < / a >, space debris will burn when entering the atmosphere, , the main satellite , is equipped with a magnet docking plate, and a GPS system, which can accurately analyze the position and motion of space debris targets. < / P > < p > in this test mission, the company will test whether - main satellite - docking with - sub module > in three independent demonstrations. In the first operation, - Main satellite - will release the test fragment, and then quickly capture it; next, - main satellite > will try to magnetically dock - sub module , and its flight speed will reach 18000 mph; finally, astroscale satellite will simulate a real operation, and - main satellite - needs to search, locate and capture - sub module > from a certain distance. If the technology is feasible, the magnetic capture device of elsa-d system will be installed on future satellites. < / P > < p > Nobu, founder and CEO of astroscale Okada said that while we have proved that the space mission has the ability to remove space debris, the elsa-d mission will further promote the regulatory work and actively promote the business case of space debris and garbage removal service. The successful launch will bring us closer to our vision for the future, determine the space safety and sustainable development, and benefit future generations. (Kamala) < / P > < p >
