World Space Week, 4-10 October

What is World Space Week?

The United Nations General Assembly declared in 1999 that World Space Week (WSW) will be held each year from October 4-10. The dates were in recognition of the October 4, 1957 launch of the first human-made Earth satellite, Sputnik 1, thus opening the way for space exploration and the October 10, 1967 entry into force 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.

World Space Week is an international celebration of science and technology and their contribution to the betterment of the human condition. 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
  • Foster international cooperation in space outreach and education

Where and how is World Space Week celebrated?

During World Space Week, space education and outreach events are organised by space agencies, aerospace companies, schools, planetaria, museums, and astronomy clubs around the world. Find an event near you!

World Space Week 2022

The 2022 theme of World Space Week is "Space and Sustainability", underscoring the value of space for achieving a better future while ensuring that space activities are conducted in a sustainable manner. 

In 2022, we are also celebrating the 65th anniversary of the launch of Sputnik 1 and the 55th anniversary of the entry into force of the Outer Space Treaty, making the occasion even more special. 

UNOOSA Webinar Series - 5 October

Sustainability from space: Satellites as our eyes towards a better future

As the only United Nations entity dedicated to space affairs, the UN Office for Outer Space Affairs (UNOOSA) is uniquely positioned to raise awareness about space exploration and use, benefits stemming from humanity's activities in space, and sustainable use of this unique environment.

This World Space Week, UNOOSA organizes an event series aimed at advancing awareness about sustainable space exploration for a sustainable planet.

Space benefiting the work of the United Nations
10 - 11:30 AM


We live in an era riddled with interconnected global crises and megatrends which are defining the course of action and progress toward a sustainable world. Climate change wreaks havoc, impacting the hardest those, who have contributed the least. Urbanization bolsters the demand for resources and carbon emissions. Inequalities are fuelling division, mistrust, and hardship. 

The United Nations has played an integral part in sustainable development and continues to deliver on its promise of a better future for everyone, everywhere. As we celebrate the annual World Space Week themed 'Space and Sustainability', let us 1) Explore the value of space assets for the delivery of the UN mandates; 2) Provide an update about the latest SDG-related efforts using space assets; and 3) Discuss the space-related user-needs to take the implementation of SDGs to another level.

Using satellites to inspire change
2 - 3:30 PM


The introduction of the space age in the 1950s with the launch of Sputnik-1 opened a treasure chest of opportunities, the extent of which were unforeseen when the first beeps beamed back from the first satellite back to Earth. Today, satellites underpin the global economy, power supply chains, and transportation, support climate science and action and help us address emergencies and disasters.

Solutions to the challenges we face require the involvement of all available assets and space exploration and utilization represent potent tools to drive sustainable development. Join the webinar that 1) Presents state-of-the-art space applications and services on offer; 2) Provides insights into possibilities of the future and benefits of integration of frontier technologies, and 3) Briefs on the services providers can offer to advance SDG efforts.
