"The world's first experiment using lasers for radio transmission will be conducted on the International Space Station, " said Liu Yupeng, a reporter for the Global Times. Russian "Energy" rocket space company experts revealed that the company plans to use lasers for wireless transmission experiments, for future space energy transmission feasibility tests.

Reported that, "code-named 'Yu' this space experiment, refers to the spacecraft between the use of laser transmission, it has been included in the Russian part of the International Space Station long-term scientific experiment program." To that end, the company will place launchers outside the Russian segment of the International Space Station and install receivers on the Progress cargo spacecraft. The remote transmission experiment will be tested first at a distance of 1 km and gradually increased in power, followed by testing within a distance of 5 km. Reported that this will be the world's first similar space experiments, such technology can be used to power the Small Satellite Constellation and other spacecraft orbiting the International Space Station. In addition, in the future, transmissions could be made from space solar power stations to remote areas of the planet, as well as to lunar rovers in lunar orbit.

Russian media said that Russia's "energy" rocket space company as early as October 2016 had conducted a ground experiment, using lasers from one of the company's roofs to a distance of 1.5 kilometers mounted on the other roof of the smartphone transmission. Following the success of the experiment, the company announced plans to conduct experiments on the space station: transferring electricity from the International Space Station to the Progress cargo ship, 1-2 kilometers away.

Russian scientists believe the wireless transmission technology could also be used to charge satellites in orbit and extend their useful life. At present, the efficiency of photovoltaic converters has reached 60%, so the use of lasers from one spacecraft to another spacecraft to transmit electrical energy is very effective. If the space radio transmission experiment is successful, it will allow future transmission of electricity from spacecraft with powerful power generation capabilities to other spacecraft equipped with receiving-converters, said Vyacheslav Tuganko, head of energy systems for the next generation of spacecraft at Energy. Microsatellite technology, for example, is developing rapidly, but these satellites carry limited energy and therefore typically have a life span of only a few months to several years. If long-range wireless charging in space is successful, it will open up a whole new field of spaceflight.
