Flight rescue of astronaut lives after the Soyuz launch

Two American and Russian astronauts safely landed after the Soyuz board boarded the ISS station that had a problem in the propulsion floor due to ballistic flight.

Russia's Soyuz spacecraft transports two new members to the International Space Station (ISS) after it launches at Baikonur airport in Kazakhstan on October 11. NASA astronaut Nick Hague and Alexey Ovchinin of Roscosmos have to abort their flight and make an emergency landing with the cabin, according to Popular Mechanics.

The search and rescue team used a helicopter to check and reach two astronauts. The original image shows that both are in good health.

When explaining this incident, NASA repeatedly referred to the term "ballistic reentry" and "ballistic mode" (ballistic mode) . Ballistic mode is a way to return to Earth's atmosphere by engineers integrated into the design of Soyuz spacecraft to prevent unexpected risks. This is the 4th time this mode is used in Soyuz program history.

Closed compartments (capsule) in ballistic episodes are responsible for extremely fast speed reduction to safely ground. Instead of a long and straight flight in controlled gyration, ballistic retrieval has a short and steep flight path. The closed chamber of the closed chamber creates the necessary atmospheric resistance to slow its fall rate.

This situation is extremely difficult for astronauts. This method increases the acceleration force (G force) on their body. The flight greatly affected the body through force G. When the cabin was straight, the forces were within the body's tolerance limits. But when changing the speed, the accelerating force that astronauts suffer will lead to a strong physiological response, the most impact on the circulatory system and can cause unconsciousness.

For example, when Soyuz TMA-1 flew in ballistic return in 2008, the crew suffered 8G gravity compared to the 6G they experienced in a controlled episode. This journey made the Korean astronaut Yi So-yeon hospitalized for injuries to his neck muscles and bruises in his spine. According to the recent failed launch, the astronauts had to suffer G forces of 6-7G.

The chamber was soaring during the ballistic recovery, but still had to maintain stability. If the Soyuz ship is disoriented, the chamber may be exposed to the exit door instead of the shield, making the temperature rise to 1,649 degrees Celsius, killing astronauts. To avoid this outcome, the Soyuz vessel rotates its orbital axis on a falling road to increase stability, similar to a bullet fired from a rifle barrel.

, the astronaut survived the ballistic revival in 2008, describing the experience as a car accident causing nausea."It is like a person being bumped and falling , " Whitson said. "I felt my face pulled back. Very difficult to breathe, like breathing through the stomach, using a diaphragm instead of the chest muscle." That's the result when G force forces a person into a chair at 8 times the normal gravity.

Ballistic movement may be an intense flight, but the first astronauts like Yuri Gagarin and John Glenn have no other option to return to Earth. In the end, engineers designed the enclosed compartment to create lift, making the flight path flatter and less uncomfortable.
