The cosmos is not only captivating but also poses deadly hazards, challenging human endurance in the quest to conquer space.
The desire to explore the universe stems from the aspiration to unravel the endless mysteries of the sky and pave the way for a better life for humanity. Each astronaut, engineer, and scientist contributing to this mission carries a timeless dream, striving for lofty goals.
The universe symbolizes greatness, yet it is fraught with challenges. However, as long as humanity does not forget its original ideals, continues to unite and contribute, barriers will be overcome, paving the way for new glories.
Throughout the history of scientific development, manned spaceflight has always represented the pinnacle of human creativity and aspiration. Achievements in this field are not only symbols of technological advancement but also represent human resilience and the determination to transcend seemingly insurmountable limits.
The beauty of space is overshadowed by its hidden dangers. The film “Salyut 7” (2017) depicts a real incident from 1985 when Russia completely lost contact with the Salyut 7 space station. Two top astronauts were tasked with a rescue mission, facing a series of risks such as equipment failures and power loss.
In extremely harsh conditions, they successfully stabilized the space station, becoming symbols of heroism and unwavering human will. The film not only celebrates the power of aerospace technology but also vividly illustrates the human spirit of exploration.
Space Science: The Pinnacle of Human Technology
Manned spaceflight is an achievement that reflects the essence of various scientific fields, including engineering, astronomy, physics, and space medicine. Each advancement in this area requires a close integration of precision engineering, breakthrough creativity, and extensive applied research.
Space is an extremely dangerous environment.
Space technology not only requires the ability to build safe spacecraft but also demands a deep understanding of how humans interact with microgravity, extreme temperatures, and cosmic pressure. These efforts require the relentless contributions of scientists, engineers, and astronauts who have turned the dream of space travel into reality.
What happens if you take no equipment into space?
Space is an extremely dangerous environment, presenting life-and-death challenges for humans. Temperatures in space can drop to -100 degrees Celsius, yet the thin air causes the body to lose heat slowly through radiation. In a vacuum, body tissues can expand, bodily fluids can freeze, and solar radiation can cause severe burns.
If an astronaut loses the protection of their spacesuit, they can only survive for 15 seconds before losing consciousness and dying within minutes. Modern spacesuits must provide protection, oxygen, and resistance to dangerous effects.
Moreover, the risk of oxygen deprivation in space is also a significant threat. Air from the lungs is quickly sucked out in a pressure-less environment. This requires astronauts to undergo rigorous training to enhance their reflexes and emergency response skills.

Survival in space often depends on every second. In the event of an accident, astronauts can rely on two options: parachuting in space or waiting for rescue teams.
Parachuting from space was tested by Joe Kittinger in 1960. He jumped from a height of 31 km and survived, setting a world record. In 2014, Alan Eustace from Google broke that record by jumping from 41.4 km. These achievements demonstrate the potential for survival when parachuting from the stratosphere with proper protective gear.
Additionally, modern space stations are designed with escape pods and emergency evacuation systems, increasing survival chances in the event of a disaster. However, utilizing these systems requires astronauts to undergo specialized training and thorough preparation.
Every advancement in aerospace not only reflects a nation’s technological prowess but also symbolizes the boundless human spirit of creativity and exploration. Space is not just a testing ground for human capabilities; it also opens new opportunities to understand ourselves and our place in the vast universe.
The journey of space exploration, despite its dangers, remains an endless source of inspiration, urging humanity to transcend all limits to conquer the impossible. On this journey, every participant contributes to the heroic chapter of humanity in exploring the universe.
