MOSCOW, March 20. /TASS/. Scientific equipment to create a detailed map of the sky within three years will be installed on Russia’s segment of the International Space Station (ISS), a leading Russian space scientist told TASS on Wednesday.

"The complex will be installed at a Russian module of the ISS. There are some universal slots on its hull, so it will be installed in one of them," said Mikhail Pavlinsky, the dead of the High Energy Astrophysics department of the Russian Space Science Institute.

He said the contract to build the equipment was signed in late 2018. "We hope that it will be ready by year-end," Pavlinsky said.

According to the scientist, the system, allowing to "create a map of 83% of the sky," will be delivered by a cargo spacecraft as early as in 2020 if it is manufactured in time.

Initially, the project was scheduled to begin in 2012.
