Humanity's exploration of the vast cosmos continues unabated. However, a persistent technological challenge shadows this pursuit of the stars, a formidable hurdle testing the courage and psychological fortitude of astronauts: the terrifying "blackout zone." This period of communication blackout, lasting 4 to 6 minutes, not only presents extreme heat and weightlessness but also immense psychological pressure, even determining the life or death of the astronauts.

The concept of the blackout zone originated in the 1950s, during the nascent stages of space exploration. In early space missions, while astronauts could float freely in space, they lacked autonomous control during atmospheric re-entry. They relied on re-entry capsules, hurtling into the atmosphere at bullet-like speeds. The capsule, a protective shell around the astronaut, endured a drastic deceleration. During this process, intense friction with the atmosphere generated extreme heat, resembling a meteor streaking across the sky.

More unsettling, the capsule's high speed created a "plasma sheath" around it. This plasma acted as a thick barrier, obstructing radio waves and causing complete communication loss between the capsule and ground control the "blackout zone." This sudden silence, akin to a cardiac arrest, inflicted immense psychological pressure on both astronauts and ground personnel.

Imagine the astronaut, subjected to intense deceleration, extreme heat, weightlessness, and isolating darkness. This is an ultimate physiological and psychological test. Any minor error could lead to irreversible tragedy.

History's painful lessons highlight the blackout zone's danger. The Soyuz 11 tragedy on June 30, 1971, remains a poignant reminder. Three astronauts perished during re-entry when a catastrophic malfunction in the return capsule caused its destruction within the blackout zone. Heartbreakingly, Soyuz 11 attempted to contact ground control before entering the blackout, sending distress signals. Ground personnel, seeing the capsule reappear on their screens after entering the atmosphere, were gripped by fear and disbelief. However, the communication blackout prevented timely rescue, resulting in an irreparable tragedy.

The blackout zone tests not only the reliability of space technology but also the psychological resilience of astronauts. During those critical 4 to 6 minutes, astronauts must confront extreme heat, weightlessness, and the terror of complete isolation. They cannot seek help; reliance is solely on their training and mental strength to calmly handle emergencies. Ground personnel also endure immense pressure, anxiously awaiting the safe landing of the re-entry capsule, each second feeling like an eternity in their helpless situation.

The blackout zone is an insurmountable obstacle in space exploration, a dual psychological and physiological ordeal requiring astronauts to possess exceptional mental fortitude and the ability to calmly react to unexpected events. Even experienced astronauts consider each passage through the blackout zone a perilous challenge.

By 2022, we have successfully launched and returned numerous astronauts to Earth. These heroes have all, to varying degrees, faced the blackout zone. Whether veterans performing numerous tasks on the Tiangong space station or pioneers forging new paths in international cooperation, every astronaut describes the experience as "perilous."

In weightlessness, even with a meticulously crafted plan, astronauts might fail due to unsteady limb control. The visual stimuli within the blackout zone also demand exceptional mental strength and emotional control.

We often use the term "communication loss," but in spaceflight, it doesn't always equate to danger. Communication interruptions occur frequently throughout a mission, particularly during orbital operations due to distance and signal delay. Even with delayed video feeds, ground control cannot always respond effectively to emergencies.

For experienced astronauts, communication loss is not the most terrifying aspect; they are prepared. However, for younger astronauts, the 46 minutes of complete isolation pose a significant psychological challenge. The feeling of hope amidst darkness, coupled with the inability to connect with the outside world, can overwhelm anyone. Moreover, communication loss creates substantial uncertainty for the entire mission team. The astronauts' safety is completely unknown during those minutes, leaving ground personnel in agonizing suspense.

The blackout zone is not just a technological challenge; it's a test of human psychological resilience. This pushes us to continually improve aerospace technology and enhance astronaut psychological training to ensure mission safety. We believe that with technological advancements and increasing exploration, we will better overcome the challenges presented by the blackout zone, ushering in a new era of space exploration. The courage and perseverance astronauts display in facing this "death zone" exemplify the spirit of human space exploration. They fearlessly challenge themselves, pursuing their dreams through life-risking endeavors. The name itself "blackout zone" evokes mystery and fear, yet it symbolizes humanity's confrontation and conquest of the unknown; a drive that propels progress, exploration, and ultimately, reaching the far shores of the cosmos.
