The Progress M-UM tug then detached from Prichal on Dec. The Prichal module – the white sphere in the center – docked to the ISS, with its Progress M-UM tug still attached. This will allow for future expansion of the Russian segment, or for additional visiting vehicles to dock at the Station. Prichal is a “Nodal” module, meaning it is spherical in nature and features six docking ports. Russia’s Prichal module then docked to the nadir port on November 26, while attached to Progress M-UM – a modified Progress propulsion section that maneuvered and docked Prichal to the Station. Progress MS-17 later docked to the module and departed on November 25, taking with it a temporary docking adaptor – freeing the port for Prichal. Soyuz MS-18 became the only Soyuz spacecraft to dock to the nadir port on Nauka on September 28, before undocking the following month. #International space station 2021 installThey were also able to install EVA handles on Nauka. Both EVAs installed ethernet cables, connecting Nauka with both the US Orbital Segment (USOS) and Zvezda. The following Extra-Vehicular Activity (EVA) occurred on September 9. At 9:29am ET, the Nauka science module arrived at the Earth-facing side of the Russian segment: /svwaYm5UGSįollowing docking, the first of two Russian spacewalks to integrate and outfit the new module occurred on September 3 by Novitsky and Dubrov.

Overcoming communications and propulsion issues, Nauka finally docked to the nadir – or Earth-facing – port on Zvezda on July 29. The departure of Pirs and Progress occurred after the successful launch of the Nauka Multipurpose Laboratory Module (MLM) which launched on July 21 on a Proton-M rocket from Baikonur. In total, Pirs spent 19 years on the ISS. For its undocking, instead of simply undocking from Pirs, the latches holding Pirs to the rest of the Station were unhooked, allowing Progress to carry the old module away from the Station.īoth Progress and Pirs then reentered the atmosphere and were destroyed the same day. Progress had originally docked to Pirs on February 17th. Progress MS-16 – a cargo resupply spacecraft – undocked from the Station on July 26th, bringing Pirs along with it. The second spacewalk – performed by cosmonauts Oleg Novitsky and Pytor Dubrov – occurred in June 2021 and successfully moved the Strela crane to the Poisk module and removed docking antennas on Pirs. #International space station 2021 series(Credit: NASA)Ī series of two Russian spacewalks occurred to decommission Pirs prior to departure. In July, the space station tilted out of orbit after the thrusters of the Nauka module reignited several hours after docking.Pirs leaving the Station with Progress MS-16. The Russian segment of the ISS has experienced a number of problems in recent months. Peresild and Shipenko are set to go back to Earth with cosmonaut Oleg Novitsky, who has been on the space station for the past six months. #International space station 2021 movieRussian actress Yulia Peresild and film director Klim Shipenko travelled to the ISS earlier this month to make the first movie in orbit ahead of the United States. "The station and the crew are not in danger." "As a result, the International Space Station temporarily changed its position," Roscosmos said in a statement. Russia's Roscosmos space agency said the incident happened during tests of the engines of the Soyuz MS-18 spacecraft set to return a Russian actress and filmmaker aboard the ISS to Earth on Sunday. The International Space Station was briefly destabilized Friday during tests of a Russian-made Soyuz rocket, but the crew and the orbital station were not in danger, Moscow said.
