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
2026 is
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.
Since the dawn of the Space Age, launch vehicles have been our gateway beyond Earth. Today, modern launch technologies are reshaping how we access space—from deploying satellites and scientific missions to developing more efficient and reusable systems—opening new horizons for exploration and innovation.
A launch vehicle is designed to generate enough thrust to overcome Earth’s gravity and travel through the upper atmosphere into space. Launch vehicles carry satellites, spacecraft, and scientific instruments to their designated orbits or destinations.
A launch vehicle begins its journey from a launch pad, where its engines generate the thrust needed to propel it upward. As it climbs, stages that have completed their role are progressively jettisoned, reducing the vehicle’s mass and allowing it to continue accelerating until the payload reaches its designated orbit or trajectory.
Reaching space requires overcoming gravity and achieving extremely high speeds. Launch vehicles provide the energy needed to transport payloads from Earth’s surface into space with precision and safety.
Propellants burn inside the engines and produce high-velocity gases, generating a force that propels the vehicle upward in the opposite direction.
The launch vehicle continues to gain speed and altitude as propellant is consumed and its mass gradually decreases.
In multi-stage launch vehicles, sections that have completed their role separate from the vehicle to reduce mass and improve efficiency for the remainder of the journey.
Once the required speed and altitude are achieved, the payload separates from the launch vehicle and begins its mission in orbit or continues toward its intended destination.
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 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.
The International Space Station (ISS).
The Tiangong Space Station.
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.
