World Space Week 2025

World Space Week, held annually from October 4 to 10 and designated by the United Nations, is the largest global event dedicated to promoting awareness of space, science, and technology, and their vital role in advancing humanity and improving life on Earth.
Each year features a unique theme that highlights a key aspect of space exploration. The theme for 2025 is "Living in Space."

LIVING IN SPACE LIVING IN SPACE LIVING IN SPACE

Space
It is the vast expanse beyond Earth's atmosphere that contains stars, planets, moons, galaxies, and all other celestial bodies in the universe.

The Beginning of Space
Space is commonly defined as beginning at the Kármán line, located at an altitude of approximately 100 kilometers above Earth's sea level. This boundary marks the point where the atmosphere becomes too thin to support conventional flight, and everything beyond it is generally considered outer space.

Space Exploration:
Space as a Unique Laboratory

Space provides a distinct environment marked by microgravity and exposure to cosmic radiation, enabling scientists to investigate how these conditions affect different materials and living organisms.

Deepening Understanding of the Universe

Through space telescopes and exploratory missions, scientists can examine celestial bodies and gain a deeper understanding of the universe's formation and the evolution of life beyond Earth.

Advancing Life Sciences and Medicine

Research into the effects of microgravity on the human body is instrumental in understanding conditions like bone mass loss and muscle atrophy, while also contributing to the development of innovative medical treatments.

Pushing the Boundaries of Science and Technology

Space exploration acts as a driver for the development of cutting-edge technologies that improve the quality of human life.

Types of Space Exploration Missions

Space exploration missions are conducted to study space and celestial bodies - such as planets, stars, comets, and galaxies - using advanced instruments and technologies. These missions are broadly categorized into manned and unmanned missions, based upon their specific scientific objectives.

  • Unmanned Missions
  • Manned Missions

Unmanned missions are carried out using specialized spacecraft and instruments without astronauts on board.

  • Satellites
  • Space Probes
  • Landers
  • Rovers
  • Space Telescopes
  • Manned missions are conducted by astronauts during their assignments in space.
  • Suborbital Missions
  • Orbital Missions
  • Space Station Missions
  • Lunar Missions and Deep Space Missions

Living in Space Requirements

Sustaining human life in space requires advanced technologies that allow astronauts to travel, breathe, and move safely in the harsh environments that would otherwise be uninhabitable without artificial support. The key technologies that support life in space include:

Space Stations:

Space stations are advanced structures that orbit Earth or other celestial bodies. Designed as state-of-the-art laboratories, they provide conditions that support human life and enable scientific research. They stand as a major milestone in humanity's pursuit of space exploration and form an essential stepping stone toward future habitation beyond Earth.

  • Despite the continuous gravitational pull of Earth, space stations remain in orbit instead of falling. This stability results from a dynamic equilibrium between their high forward orbital velocity and the steady gravitational force pulling them toward Earth's center.
  • Earth's gravity pulls all objects toward its center. However, the space station's tremendous forward orbital velocity - around 28,000 kilometers per hour - balances its force, preventing it from falling back to Earth. This delicate balance results in a state of “continuous free fall,” keeping the station in a stable orbit around the planet.
  • A space station is a highly advanced and technologically complex structure designed to support astronauts' life in Earth's orbit. Operating as a self-sufficient system, it manages essential resources such as air, water, energy, and communications, while also regulating internal temperature and handling waste disposal.
  • Current Space Stations:
  • The International Space Station (ISS).
  • The Tiangong Space Station.
Spacecraft:

    Spacecraft function as mobile habitats, providing astronauts with the essential conditions for living and working in space. These vehicles are equipped with advanced technological systems that ensure safety, life support, and protection from the harsh environment beyond Earth.
    Key technologies integrated into spacecraft include:

  • Temperature and Pressure Control.
  • Space Radiation Protection.
  • Nutrition and Food Storage.
  • Life Support Systems.
Space Suits:
Core Function:

The space suit functions as a mobile personal spacecraft, providing protection and life support during extravehicular activities. It is designed to shield astronauts from radiation and micrometeoroid debris, supply breathable air, maintain a suitable body pressure, and regulate temperature through an integrated thermal control system.


Suit Components:
  • Life Support System: It supplies oxygen, regulates body temperature, and maintains appropriate humidity and internal pressure.
  • Protective Layers: They prevent pressure loss and protect against micrometeoroid debris.
  • Communication System: It allows astronaut to stay in contact with their crewmates and the space station.
  • Gloves and Helmet: The gloves are designed for both flexibility and protection, while the helmet safeguards against harmful solar radiation.
