The Center Khrunichev said that when the module "Science" will be sent to Baikonur

Russian module Nauka is planned to send to the Baikonur cosmodrome in July, to launch to the International space station, said the General designer of KB "salute" of Khrunichev Centre Sergey Kuznetsov.

It is noted that in the past week have been completed leak tests of the module body of "Science" and its docking units, and confirmed the operation of the pneumo-hydraulic propulsion system and external hydraulic circuits. In a vacuum chamber held pneumovacuum tanks tests module.

The start of the module planned in the spring and summer of 2021 carrier rocket "proton-M" from Baikonur cosmodrome.

Module "Science" was started in 1995 as a ground-based alternate first module of ISS Zarya. In 2004 it was decided to save on the creation of a new compartment of the Russian segment of the station and to convert the "double" in full flight module. Its launch was appointed on 2007, however the deadline to complete the manufacture did not, delaying the launch of the year.

In 2013, after the transfer of the module from the manufacturer- the Khrunichev Center – in Rocket-space Corporation "Energy" for the provision of internal equipment, during testing it turned out that the fuel system contains foreign particles. This threatens to damage the whole propulsion system of the ISS when pumping fuel, so it was decided to return the module to the manufacturer for revision.

In the module "Science" will be located berth for the third Russian cosmonaut (cabins for two astronauts are in the module "Zvezda"), as well as a second toilet in the Russian segment of the station (there is one toilet in the Zvezda module).
