A block of lasers for spacecraft that will be able to display advertising from space has been tested in the stratosphere. This was reported to TASS on Thursday by the press service of the developer company Avant Space.
“The laser unit was launched into the stratosphere to an altitude of about 30 km in order to confirm the design level of power of the light source in conditions close to space,” the company noted.
As a result of the experiment, all calculations were confirmed, the developer said. “The future artificial constellation of satellites will become the brightest star in the night sky, comparable to the brightness of Venus,” the press service explained.
The company emphasized that the glow of the devices will not create problems for astronomers’ observations. “The lasers on the satellites will turn on only when flying over the planet’s major cities and will be focused in such a way as not to go beyond the city limits,” the press service added.
It will be possible to track such constellations using a special mobile application, which is currently being developed.
“Constellation”
In February, the director of the project implementation department of the United Rocket and Space Corporation (URSC), Andrei Divaev, told TASS that the first two microsatellites with laser diodes, with the help of which it will be possible to write messages in the sky in the future, will go into orbit in 2022. According to him, the devices will be controlled as part of a swarm of satellites that will be sent into orbit in the future as part of the Constellation experiment.
