21 seconds before liftoff, the launch of the Roscosmos Soyuz MS-25 spacecraft automatically stopped at the Baikonur Cosmodrome, reports said. Ars Technica.
Three people on board the spacecraft – Belarusian Marina Vasilitskaya, Russian Oleg Novitsky, and American Tracy C. Dyson – were supposed to head to the International Space Station.
It is not known exactly what technical error caused the launch failure – A CNN According to his information, one of the two wires connecting the launch pad to the launch vehicle was not cut in time, and therefore the engine was unable to start.
The Soyuz spacecraft and its namesake launch vehicle have been used by the former Soviet and Russian space programs since 1966, and in nearly sixty years have become their most mature and reliable spacecraft. After more than 2,000 launches, it is a fairly robust vehicle that can be launched regardless of the weather, even in a snowstorm.
The crew was not in danger at the time of the emergency stop. The next attempt to launch the spacecraft will be on Saturday. A minor inconvenience for the astronauts is that they would have arrived at the ISS in about three hours during Thursday's missed launch — if they succeeded, due to orbital dynamics after Saturday's launch, they would have been able to dock at the station on Monday at the earliest, so they would have to spend More time in a very cramped Russian spaceship.
The launch voucher did not affect SpaceX's 30th cargo flight. With food and all supplies on board, the Cargo Dragon ship departed Florida on time and is expected to arrive on Saturday at the International Space Station, where three Russian and three American astronauts are currently staying.
