Soyuz MS-19 will land in Kazakhstan amid US-Russian relations

At 07:21 UTC on March 30, Soyuz MS-19 will take off from the International Space Station (ISS) and then land in the Kazakh Steppe at about 11:29 UTC later that day. This would end the five -month mission for the plane, and the second year for an American missionary.

The crew of Soyuz MS -19 will be joined by Russian cosmonauts Anton Shkaplerov – serving as commander – and Pyotr Dubrov of Roscosmos and American Mark Vande Hei of NASA. Dubrov and Vande Hei were released on Soyuz MS-18 on April 9, 2021, and spent a long time on the ISS.

The landing of Soyuz MS-19 came as the Russian-American embargo rose after Russia’s invasion of Ukraine, which began on 24 February. .

Despite widespread rumors that Vande Hei may not be flying the Soyuz, Joel Montelboano – ISS Program Director – said Vande Hei would land as a master plan, on the Russian Soyuz.

Upon landing, Vande Hei spent 355 direct days in the air – more than any other American. This replaces the same flight story created by Scott Kelly in 2016, who spent 340 days in the air. Other American pilots who made long -distance flights were Christina Koch, Peggy Whitson, and Drew Morgan.

For Shkaplerov – who was born in Sevastopol, Ukraine SSR (Crimea) – the Soyuz MS -19 was his fourth aircraft. He served as Director of Expedition 66.

This was the first aircraft for Dubrov who, according to Vande Hei, also spent 355 days in the air.

Soyuz MS-19 was launched aboard a Soyuz 2.1a rocket from Site 31/6 at the Baikonur Cosmodrome in Kazakhstan on October 5, 2021. The aircraft took Shkaplerov with Russian pilots Klim Shipenko and Yulia Peresild.

Shipenko and Peresild flew to the ISS to film a movie called “The Challenge”, starring Shipenko and the actor Peresild.

Soyuz MS -19 was designed to be controlled by a single cosmonaut – in this case Anton Shkaplerov. This was done so as to reduce the training time for those who boarded the aircraft on the voyage to the ISS.

Shipenko and Peresild returned to Earth 12 days after Soyuz MS-18.

The Soyuz MS-21 crew, consisting of Oleg Artemyev, Denis Matveev, and Sergey Korsakov, arrived on the ISS on March 18. They will replace the three-man crew that departed from Soyuz MS-19. .

Removal
Prior to the launch, Shkaplerov would issue an order for the Soyuz spacecraft to remove the lock from the Rassvet jetty. Then, the fears in the docking ring (the center between the Rassvet Module and Soyuz) begin to open. This will be followed by detachment and physical separation one minute after 07:21 UTC.

When the aircraft is detached, the springs in the docking system slowly move the aircraft from the Rassvet module at a speed of 0.12 m / s. As a docking, the Kurs-Na docking system will be used.

With the departure of the Soyuz, Expedition 67 will begin aboard the ISS.

Separation Burn-1 starts and lasts eight seconds. This will be followed by Separation Burn-2, with a duration of 15 seconds. This fire will leave Soyuz MS-19 in the Keep Out Sphere, a 200-meter circle around the ISS.

After leaving the ISS space, the Soyuz spacecraft will begin a period of free flight.

Deorbit and landing
Before deorbiting, the Soyuz spacecraft will reposition itself retrograde. The aircraft will then be instructed to fire its single S5.80 engine, located on the aircraft’s propulsion module. S5.80 is a fully charged engine running on dinitrogen tetroxide (N2O4) and unsymmetrical dimethylhydrazine (UDMH), toxic hypergolic fuels.

The fire will continue for about four minutes. After the fire, the plane and its passengers will be detained for re -entry and landing.

Soyuz MS-19 is operating in the northeastern part of Egypt over Egypt, bombs will be fired on the aircraft, separating the orbital and propulsion modules from the descent module, where available and to the sailors.

Currently, the spacecraft is located about 140 km above Earth.

As the aircraft lands over the Caspian Sea, the module itself enters the plasma state when it re -enters the sky. In the meantime, there are people in a dark age, where plasma is built around the car to record conversations between teams and global pilots at Roscosmos Mission Control in Korolev, Russia.

After going into the air, the radio team will once again have missionary power and rescue teams stationed around the healing area.

To extend the ride, the two parachutes will be mounted at about 10 km in altitude after the parachute cover is placed on the side of the Descent module. Then, the drogue parachute will be placed before the single large parachute is dropped.

At 5 km altitude, the heat shield will open, as will the Boeing CST-100 Starliner. The aircraft will release the remaining accelerators. Before landing, the occupants had to stand up and straighten the landing.

Prior to landing, the vehicles will fire under the Descent module at a height of 0.7 meters above the ground to complete the impact. Sailors are scheduled to land in the Kazakh Steppe at 11:29 UTC.

Russian return cars are used for the return. Yes: NASA TV.

After landing, Russian rescue forces will evacuate Shkaplerov, Dubrov, and Vande Hei from the Soyuz spacecraft.

After an initial medical examination after the flight, the Soyuz MS-19 spacecraft will proceed on their own route. Shkaplerov and Dubrov will probably be flying to Star City, Russia near Moscow.

Vande Hei, on the other hand, will board a NASA plane and return to Houston, Texas with other NASA crew members. Unlike similar missions in the past, the NASA spacecraft had to defend the Russian spacecraft.
