On Friday, the ISS lost its orientation in space while testing engines of the Soyuz MS-18 manned spacecraft.
The ISS crew was woken up at night by a siren that went off at the International Space Station due to a malfunction in the control system of the Russian Zvezda module, it follows from the crew's talks with the Earth, which were broadcast by NASA.

"We have now triggered an alert <...> A second later it was removed. But there was a siren at the station. And to our colleagues, I did not beat off so that they could hear," cosmonaut Anton Shkaplerov said to a specialist from the Mission Control Center.

According to him, the reason was the temporary loss of readiness of navigation support in the motion control and navigation system of the Zvezda module.
Later, a specialist at the Houston Mission Control Center informed the crew that no action was required from them.
Earlier, ISS lost its orientation during a test of the engines of the Soyuz MS-18 spacecraft - it turned 57 degrees. Half an hour later, the position of the station in space was restored using the engines of the Russian module.
The current ISS crew comprises Russian cosmonauts Oleg Novitskiy and Pyotr Dubrov; NASA astronauts Mark Vande Hei, Shane Kimbrough, and Megan McArthur; Japan's Akihiko Hoshide; and Thomas Pesquet of the European Space Agency, as well as a movie crew which includes Russian actress Yulia Peresild, movie director Klim Shipenko, and accompanying cosmonaut Anton Shkaplerov.
