Moscow. July 29. INTERFAX.RU – The launch of the Starliner spacecraft to the ISS, scheduled for Friday, has been postponed in order to give the station crew time to deal with the incident with the engines of the Nauka module, NASA reported.
“NASA and Boeing have decided to postpone the planned launch of the second test flight of the spacecraft (Starliner) on Friday. At the moment, the teams are considering the following possibilities. This will give the ISS crew time to check the work of the newly arrived Roskosmos” Science “module in order to prepare for the arrival of the Starliner, – the message says.
Earlier, NASA reported that an abnormal start of the engines occurred on the Nauka module docked to the ISS on Thursday, which caused the station to turn 45 degrees. To compensate for the impulse, the engines of the Zvezda module and the Progress cargo vehicle had to be used. Ground specialists managed to regain control of the station, the crew and equipment were not affected. In “Roskosmos” the incident was explained by work with the remaining fuel in the module.
As reported by NASA, the ISS crew will change the work schedule to test the new module.
On July 23, it was reported that NASA and Boeing approved a NASA Boeing Orbital Flight Test-2 (OFT-2) test flight of the CST-100 Starliner spacecraft to the ISS on July 30. According to NASA, the spacecraft underwent a number of changes to address a software issue that caused a partial flight failure during the first test flight of Starliner in December 2019. The ship has passed numerous tests and underwent major changes in the docking system. The nose of the CST-100 Starliner was fitted with a protective skin similar to that used on SpaceX's Dragon Endeavor.
As a result of the checks, it was announced that the CST-100 Starliner will travel to the ISS at 14:53 ET on July 30. Approximately 24 hours after launch, the spacecraft will dock at the forward port of the Harmony module on the ISS.
The port, which will occupy the CST-100 Starliner, was liberated by the Crew Dragon on July 21, which was carrying NASA astronauts Shane Kimbrow and Megan MacArthur, JAXA astronaut Akihiko Hoshide and ESA astronaut Tom Peske.
The OFT-2 mission will test the various capabilities of the Starliner – launching, docking, re-entering the Earth's atmosphere and landing in the desert in the western United States.
