New Delhi: World Space Week kicks off today, October 4, celebrating the contributions of space science and technology that have enhanced our quality of life. The annual event runs until October 10 and focuses on space education and outreach events organised around the world by space agencies, schools, aerospace companies and astronomy clubs.
The week also commemorates two major events that revolutionised space exploration. Here’s a look at the history, significance and theme of World Space Week 2026.
History And Significance Of World Space Week
World Space Week begins on October 4 every year to commemorate the launch of Sputnik 1, the world’s first human-made satellite, in 1957.
Sputnik 1 was a metal sphere the size of a beach ball launched by the Soviet Union, marking the dawn of the space age for humanity.
October 10, meanwhile, observes the enforcement of the Outer Space Treaty in 1967. The treaty provides the basic framework on international space law and governs how countries will carry out activities in outer space, including the Moon and other celestial bodies.
On December 6, 1999, the United Nations General Assembly (UNGA) proclaimed World Space Week through resolution 54/68 and declared that the event would be celebrated every year from October 4 to 10.
The United Nations has been involved in space activities since the very beginning. Today, the United Nations Office for Outer Space Affairs (UNOOSA) is responsible for promoting international cooperation in the peaceful uses of outer space.
Theme Of World Space Week 2026
The theme of World Space Week this year is ‘Rocket Revolution’, highlighting the rapid growth of rocket launches and the transformation they have brought about by making space more accessible.
“Once limited to a small number of government programs, access to space is now expanding through commercial launch providers, reusable rockets, university teams, startups, and new national space actors,” the United Nations said in a statement.
“This shift is changing who can reach space, how often launches happen, and what space is used for.”
The theme for each year is jointly selected by the World Space Week Association Board of Directors and the UNOOSA and is uniform globally to increase the impact of the event.
Hundreds of events are organised during the space week, with the common theme guiding organisers on the contents of their programmes.
