"Liftoff! Twenty-three years and four days after the first module launched to the International Space Station, a new docking port took flight, it was a flawless ride to orbit," NASA spokesperson Rob Navias said during the agency's live broadcast.
Earlier, Roscosmos reported that the Progress MS-17 spacecraft will undock from the pressurized adapter of the Nauka module alongside with the adapter spacer, which currently provides docking of Soyuz MS and Progress MS series transport vehicles. So the Nauka module will have the possibility of regular docking with the arriving module Prichal.
Prichal will be the second Russian module to arrive at ISS in the last four months. The Nauka module reached the orbiting lab on July 29 and caused quite a stir when it did so. Nauka's engines fired in an unplanned fashion after docking, causing the ISS to rotate about 540 degrees.
The Prichal module is designed to increase the technical and operational capabilities of the Russian segment of the ISS, the space agency said.
In addition, the transport vehicle will deliver cargo weighing 700 kg to the Russian segment of the ISS.
