Moscow. July 30. INTERFAX.RU – The second test flight in unmanned mode of the Boeing corporation CST-100 Starliner to the International Space Station (ISS), which was postponed due to the incident with the Russian module “Science”, is scheduled for August 3, NASA reported.

The American space agency reported earlier 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 connection with the investigation of the incident, NASA decided to postpone the launch planned for Friday. The launch of the spacecraft, created for future flights of American astronauts into orbit, is supposed to be carried out using the Atlas 5 heavy launch vehicle from the United Launch Alliance on August 3 at 01:20 US East Coast time (08:20 Moscow time) from the 41st launch complex to spaceport at Cape Canaveral in Florida. Docking with the ISS is to take place on August 4.

During the first test flight of the spacecraft, which was conducted on December 20, 2019, it failed to dock with the ISS. The rocket successfully brought the unmanned spacecraft to a suborbital trajectory. However, after that, it encountered a problem related to a malfunction in the engine operating time calculation system, as a result of which Starliner entered an abnormal, lower orbit for rendezvous with the ISS. The spacecraft was running out of fuel, and docking with the ISS became impossible. He made a successful soft landing at White Sands Proving Ground in New Mexico. This was the first land landing of an American reentry capsule. All previous American vehicles splashed down in the ocean.

In early February, NASA announced that the first flight of Boeing's newest American spacecraft Starliner with astronauts on board to the ISS is scheduled to take place no earlier than September. As part of a contract with NASA, Boeing received more than $ 5 billion for the development, creation and implementation of Starliner missions to transport astronauts to the ISS and return them to Earth. It is designed for a crew of up to seven people. Another American company, SpaceX, under a similar contract with NASA, received $ 3.1 billion to develop its Crew Dragon spacecraft, which has already completed a number of manned flights to the ISS.
