"The launch date of the Nauka module is tentatively the end of April, but we will now look at the flight program in order to bring it to the station most comfortably, because it should fly for about a week," Daneev said.

According to him, after the integration of the "Science" module, the "Prichal" nodal module will be launched, designed for additional expansion of the Russian segment of the ISS.

It will be possible to dock only after docking of "Science".

“Now we are planning to launch it in September approximately,” he said during an online event marking the 20th anniversary of the ISS manned flight.

As the director of Roscosmos Dmitry Rogozin said earlier, the launch of the multifunctional laboratory module “Science” for the ISS is a good sign, because “Russia thus demonstrates confidence in the station, in its life, in its ability to develop further”.

The module is capable of producing oxygen for six people.

With this module, astronauts will receive a second toilet, a cabin for a third crew member and the European manipulator ERA - with it it will be possible to perform some work without going into outer space.
