The battery is dead: The reason for the cancellation of the launch of the Soyuz MS-25 spacecraft has been established

The head of Roscosmos, Yuri Borisov, announced the reason for the normal but emergency situation

The launch of the rocket with the Soyuz MS-25 spacecraft was canceled due to a “voltage drop in the chemical current source “, said the head of Roscosmos Borisov. RIA-Novosti reported this. In other words, one of the batteries of the complex did not work. As MK learned, she was responsible for disconnecting the fuel refueling mast — a mast-type metal structure designed to carry electrical cables and refueling communications.

Let us remind you that the Soyuz-2.1a launch vehicle with a manned spacecraft was supposed to launch at 16.21 Moscow time. However, at the last minute, after the “Start” command, the automation was triggered, and the launch was canceled at the countdown stage.

As MK was informed in the space industry, the cause of the emergency, which nevertheless relates to normal , a refueling mast cable that had not been removed properly appeared. According to preliminary data, because of the same sagging battery, the electromagnets that held it were not disconnected.

According to experts, the astronauts who were ready for the launch had to descend from the ship and return to the hotel for the first time in history. Russian Oleg Novitsky, Belarusian Marina Vasilevskaya and American Tracy Dyson were successfully evacuated in a special elevator to the ground.

Their health is normal. According to Borisov, Marina Vasilevskaya, who is to become the first citizen of Belarus to go into space, did not even have a pulse rise from the experience.

The launch was postponed to March 23, at 15.36 Moscow time. By the way, if at today’s launch the flight pattern was designed for two orbits, on the second attempt it will be two days long.
