The Russian segment of the ISS will add the new module
New Russian multipurpose laboratory module "Nauka" launch to the International space station in April 2021, told reporters the head of "Roskosmos" Dmitry Rogozin.
"We plan to start in April next year", - said Rogozin.
Deputy General Director of the Khrunichev Centre for the production of Roman Khokhlov added that the sending module to the launch site from Moscow on 6 August, a subsequent training will take nine months.
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, but then for various reasons, repeatedly postponed.
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. Their presence could result in damage to the propulsion system throughout the ISS when pumping fuel so the decision was made 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).
