The CEO of Roscosmos previously reported that a single-turn flight scheme could be tested in 2022
MOSCOW, December 31. /tass/. Single-turn flights on spacecraft to the ISS will begin soon. This was announced by the general director of the state corporation Dmitry Rogozin during a conversation with the crew members of the station.
"We have a light ship [Soyuz MS]. Yes, it's a little tight. But [it flies] in three hours, and soon we will fly for 1.5 - 2 hours, according to a shorter scheme. This is a normal ship that will serve for several years," Rogozin said.
In April 2019, RSC Energia developed a single-turn scheme for spacecraft rendezvous with the ISS, for the first time its elements were tested during the flight of the Progress MS-17 spacecraft. Roscosmos CEO Dmitry Rogozin told reporters that a single-turn flight scheme to the ISS could be tested in 2022.
As the head of the ballistics department of RSC Energia, Rafail Murtazin, told TASS, according to the single-turn scheme, it is assumed that after launching with the help of two pulses, the ship will be in a coelliptic orbit, geometrically similar to the orbit of the ISS. With this approach, when the observation angle of the station from the ship is 23 degrees, the point of execution of the optimal pulse is unambiguously determined, which leads the ship to the vicinity of the station after half a turn.
