TEHRAN – The World Space Week - the largest annual space event in the world - will be observed from October 4 to 10.

The week helps build up the workforce of tomorrow by inspiring students; demonstrates visible public support for the space programme; educates the public about space activities; and fosters international cooperation in space outreach and education.

Each year, a theme is selected by the World Space Week Association Board of Directors in close coordination with the UN Office of Outer Space Affairs. The theme provides broad guidance to World Space Week participants on the content of their programmes. The theme is selected to increase the impact of World Space Week further on all of humanity by using a uniform theme globally.

For World Space Week 2025, the chosen theme is ‘Living in Space’. This theme explores humanity’s journey toward making space a habitat, emphasizing the innovative technologies, challenges, and collaborative efforts that make this vision a reality.

Event organizers worldwide are encouraged to integrate the theme ‘Living in Space’ into their World Space Week events. Activities may range from educational workshops and interactive sessions to panel discussions and collaborative projects, all aimed at fostering innovative environmental solutions.

The Iranian Space Agency will celebrate the event to raise public awareness by holding various scientific and educational programs for different age groups. It has named the days of the week as follows.

Saturday, October 4, ‘Living in Space’

Sunday, October 5, ‘Space habitats, engineering and design’

Monday, October 6, ‘Space climate and Space radiation’

Tuesday, October 7, ‘The Moon, a space travel station’

Wednesday, October 8, ‘Space agriculture and mining’

Thursday, October 9, ‘Life support systems in space station’

Friday, October 10, ‘Space medicine and human physiology’

The United Nations General Assembly declared in 1999 that World Space Week will be held each year from October 4-10. These dates commemorate two events. October 4, 1957: Launch of the first human-made Earth satellite, Sputnik 1, thus opening the way for space exploration

October 10, 1967: The signing of the Treaty on Principles Governing the Activities of States in the Exploration and Peaceful Uses of Outer Space, including the Moon and Other Celestial Bodies.

Holding World Space Week aims to provide unique leverage in space outreach and education, educate people around the world about the benefits that they receive from space, encourage greater use of space for sustainable economic development, demonstrate public support for space programs, excite young people about science, technology, engineering, and math, and foster international cooperation in space outreach and education.

World Space Week consists of thousands of space-related events held by space agencies, aerospace companies, schools, museums, astronomy clubs, and others in a common timeframe to achieve greater student and public impact through synchronization.
