Living Beyond Earth: The Survival of Astronauts in Space
While the NASA-rover captures the ethereal beauty of the Martian surface, the question of How do astronauts survive in space? starts sparking with a renewed vigor. It’s not a blissful vacation in the vast void but a challenging reality brought into existence by a blend of modern technology and untold courage. Let’s delve into the intricacies of life in space, the harshest environments known to mankind.
Essential Protection: The Space Suit
Few understand the importance of a space suit, a veritable lifeline for astronauts. It’s not just a piece of clothing but a mini spacecraft that maintains a consistent environment around the astronaut’s body, with a temperate climate, breathable air, and protection from micro-meteoroids.
Space Suit Components
- Pressure Garments: These consist of a hard upper torso structure, which holds life-supporting gear, and lower torso clothing made from durable materials.
- Primary Life-supporting System (PLSS): This back-pack system supplies breathable oxygen, eliminating exhaled carbon dioxide.
- Helmet and Extravehicular Visor Assembly (EVVA): This protects astronauts from bright sunlight and the vacuum of space.
Dwelling in Space: The International Space Station (ISS)
The International Space Station (ISS) is an extraterrestrial haven that orbits Earth every 90 minutes. This spacecraft provides living quarters, a gym to combat muscle atrophy, and a kitchen to cook vacuum-sealed meals.
Life Support Systems in ISS
- Oxygen Generation System (OGS): This provides oxygen for respiration and replaces oxygen lost during experiments or airlock depressurization.
- Water Recovery System (WRS): This technology turns waste water into clean water, sustainability in the void of space being of prime importance.
Coping with Zero-Gravity: The Science Behind Floating
The apparent weightlessness or zero-gravity is an attraction in its own right. However, it presents challenges like disorientation and muscle atrophy. Astronauts make use of foot restraints and handrails aboard the ISS to navigate this lack of gravity. Daily exercise is mandatory to maintain muscle mass and bone density.
Staying in Touch: Communication Systems
Astronauts stay in touch with the earth using SATCOM (satellite communication). Important data is exchanged through the Tracking and Data Relay Satellite (TDRS) system. Regular virtual conferences with family members supplement their emotional wellbeing.
FAQs about Living in Space
How do Astronauts Sleep in Space?
Space presents no up or down, so astronauts attach sleeping bags to a wall and sleep vertically. They use straps to avoid floating and to ensure a sound sleep.
What Do Astronauts Eat in Space?
Astronauts enjoy a range of meals in space, from shrimp cocktails to chicken teriyaki. Most foods are vacuum-sealed and require heating or adding water. Fresh fruits and vegetables are relished soon after a supply ship arrives.
Are there Emergency Procedures in Place for Astronauts in Space?
Yes, astronauts are meticulously trained for emergencies like fires, depressurization, and toxic leaks. Escape craft Soyuz remains docked at the ISS if evacuation becomes necessary.
Exploring the cosmos is no less than an ethereal dream, drawing its sheen from inherent risks. So, whenever you cast an eye towards the stars, remember that the story of survival in space is an undying testament to human resilience and the prowess of technology.
Taking that first step towards the stars is just as important as learning to survive among them.
