Cargo Transportation Spacecraft (CTS) Progress MS-21 has been delivered to the processing facility at the Baikonur launch site to undergo its standard processing according to the schedule of the transportation support of the Russian Segment of the International Space Station (ISS RS).

Over the last three months the CTS Progress MS-21 had undergone the full scope of in-factory check tests at S.P.Korolev RSC Energia and on October 18, 2012, was shipped off to the launch site. This morning at the processing facility of Site 254, the spacecraft was unloaded and installed into its processing station to undergo the acceptance procedure and further preparations for storage. After that, as a part of the incoming inspection operations, specialists from RSC Energia performed a visual inspection of the vehicle and checked the functioning of the solar wings deployment mechanism. CTS Progress MS-21 will remain in storage until the start of the immediate prelaunch processing.

The launch of the Soyuz-2.1a launch vehicle carrying Progress MS-21 under the program of the 82nd re-supply mission to the ISS is scheduled for fall of the next year.

Roskosmos will send a ship to the ISS in a record-breaking short scheme.

Rogozin: in October "Progress MS-21" will go to the ISS on a short single-turn scheme.

BAIKONUR COSMODROME, June 3 - RIA Novosti. The Progress MS-21 cargo ship, which is scheduled to launch on October 26, 2022, will fly to the ISS in the shortest possible single-orbit pattern, Dmitry Rogozin, CEO of Roscosmos , told reporters.

"The decision has been made, the next, autumn Progress will follow a single-turn scheme, ballistics have been calculated," he said at a press conference after the Progress MS-20 cargo spacecraft docked with the ISS .

He called the record-breaking flight practice a risk that rocket scientists are willing to take, because it is a step forward for manned astronautics. If the flight is successful, it will yield results that will make it possible to switch to flights according to the single-orbit scheme of Soyuz spacecraft with a crew, Rogozin noted. Such a launch could take place as early as the spring of 2023.

Earlier, Rogozin said that a single-turn flight pattern could be tested on the Progress MS cargo ship in the fall of 2022.

In 2022, three Progress trucks will be launched to the ISS. The first two have already arrived at the station on February 15 and June 3. The third launch is scheduled for 26 October.

The two-day scheme is traditional, when the ship makes 34 revolutions around the Earth . A four-turn circuit is also used, which lasts about six hours. So far, several Progress MS cargo ships and two manned Soyuz have flown under the two-orbit (three-hour) scheme. The flight speed record was set by Soyuz MS-17 on October 14, 2020 - 3 hours 3 minutes.

Short flight patterns allow cosmonauts to fly to the ISS faster, and therefore more comfortable, given the small volume of the Soyuz spacecraft. In addition, doctors found that after 6-7 turns (9-10.5 hours) acute negative consequences of weightlessness begin - nausea, motion sickness. Reducing the flight time allows you to meet these features of space on a large station, and not in a small ship.

Short schemes can also be used when assembling a manned complex for flying to the Moon and in lunar orbit.

MOSCOW, September 1. /TASS/. A new two-hour rendezvous with the ISS has been developed specifically for the flight of the Progress MS-21 cargo spacecraft, which is scheduled for launch in October. Rafail Murtazin, head of the ballistics department of the Rocket and Space Corporation Energia, told TASS.

"Specialists propose to implement the scheme, leaving only the existing automatic approach section. The scheme was called a two-hour one," Murtazin noted.

According to him, initially the testing of elements of the single-twist rendezvous scheme was planned on Progress MS-20, which was launched in June. However, this idea was abandoned, instead it was planned to work out a single twist in October. As a result, the specialists developed a two-hour one. "In fact, it will be 2 hours and 46 minutes. But anything less than two turns is considered a one-twist," he added.
