MOSCOW, June 27. / TASS /. Roscosmos experts listed some of the shortcomings of the SpaceX manned spacecraft Crew Dragon manufactured by Ilona Mask.

The Falcon 9 booster rocket with the Crew Dragon manned ship launched to the ISS on May 30. This is the first manned flight in nine years, carried out from the United States on an American spacecraft. The successful docking of Crew Dragon with the ISS took place on May 31.
“<...> the placement of liquid engines of huge thrust of an integrated propulsion system of the emergency rescue system right behind the wall of the cabin is alarming, “the article says.
A number of experts also questioned the safety of the “immediate vicinity of the crew and a couple of tons of toxic fuel components (nitrogen tetroxide and monomethylhydrazine – this is still not water or even hydrogen peroxide), which are supplied under pressure to the emergency rescue engines.”
In addition, according to experts, the Crew Dragon cockpit is much more spacious than the Soyuz spacecraft, since it is designed for seven astronauts. “However, NASA has reduced the crew to four people – it’s no longer needed. It turns out that in order to solve its main task of delivering people to the ISS, the new ship still looks oversized,” the article says.
The material also indicates the absence of a normal toilet in the American ship. “Astronauts flying on the shuttle complained that the toilet area was separated from the rest of the cabin with a symbolic screen during each use. But if the shuttle’s sealed cabin had a volume of 74.5 cubic meters, then the new ship has only 10 cubic meters, and the toilet is still hidden behind curtain, “- says” Russian space “.
At the same time, the article notes that the Crew Dragon is more reliable and cheaper than the shuttles that operated before the US in 2011. In addition, the shuttles had two disasters, in which 14 astronauts were killed, and Crew Dragon provides the salvation of the crew in the event of an accident at any site in the orbit.
