From NASA:’s scheduled undocking activity tomorrow is postponed, allowing the expedition 65 crew on the International Space Station more time to focus on today’s training, science, and maintenance. The Russian
Multipurpose Laboratory Module (MLM) was launched on July 21. In order to allow Russian flight controllers more time to check the status of the MLM, the disengagement of the Russian Progress 77 and Pirs docking module was postponed to Saturday in July. twenty four. Space station personnel have been notified. Disconnection of the Progress 77 and Pirs docking module is now scheduled for 8:28 AM ET.
NASA’s television station, agency website, and NASA app will begin the live broadcast at 8 AM.
On Thursday, June 29, MLM plans to stop at this station. Named Nauka after the word “science” in Russian, MLM will serve as a new scientific facility, docking port and airlock for spacewalks for future operations.
Once Pirs and Progress 77 undock from the space station on Saturday, they will perform a desorbitation maneuver to send them back to Earth and disintegrate in Earth’s atmosphere. In preparation, Russian astronauts Peter Dubrov and Oleg Nowitzki carried out a series of maintenance tasks today.
The crew is also preparing for another upcoming event: As part of NASA’s
Boeing Orbital Flight Test 2 (OFT2) mission, Boeing’s CST100 Starliner is scheduled to arrive at the space station on July 31.

NASA provides upcoming pre-launch events, Launch and docking reports the agency’s Boeing Orbital Flight Test 2 (OFT2) mission to the International Space Station. Scheduled to start EDT at 2:53 pm On Friday, July 30, OFT2 is the second unmanned flight of the Boeing CST100 Starliner spacecraft and is part of the agency’s commercial crew program.
The Starliner will use the United Launch Alliance (ULA) Atlas V rocket from Space Launch Center 41 at the Cape Canaveral Space Force Station in Florida. Approximately 31 minutes after launch, Starliner will reach its initial orbit. It is scheduled to dock at the space station at 3:06 pm. Saturday, July 31st. Pre-launch, launch and docking activities will be broadcast live on NASA TV, NASA apps and the agency’s website.
The spacecraft will deliver more than 400 pounds of NASA cargo and crew supplies to the space station, and return to Earth with more than 550 pounds of cargo, including reusable nitrogen and oxygen refueling system (NORS) tanks, to provide breathable air for the crew.
The OFT2 will demonstrate the end-to-end capabilities of the Starliner spacecraft and Atlas V rockets from launch to docking and returning to Earth in the western desert of the United States. The unmanned mission will provide NASA with valuable data to prove Boeing’s crew transportation system and the regular flights of astronauts to and from the space station.
