World Space Week 2026 is being celebrated from October 4 to 10 in countries around the world under the theme “Rocket Revolution”. It focuses on how new launch systems, reusable rockets, private companies, universities and new national players are expanding access to space.
The observance was established by the United Nations General Assembly and recalls two milestones: the launch of Sputnik 1 on October 4, 1957, and the entry into force of the Outer Space Treaty on October 10, 1967.
What “Rocket Revolution” means
For decades, placing a satellite in orbit was an activity concentrated in a small number of high-cost government programmes. The development of reusable vehicles, new launch providers and the participation of universities and startups are changing that landscape.
This does not make access to space simple or inexpensive for everyone: launches require technology, safety, funding and regulation. But greater availability of space services can support environmental monitoring, weather forecasting, connectivity, agriculture, navigation and scientific research.
Space science is part of daily life
Satellites help monitor wildfires, rainfall, oceans, farmland and changes in land use. Positioning systems, communications and weather data also depend on space infrastructure. World Space Week aims to bring students and the public closer to subjects that already shape everyday life.
Schools, astronomy clubs, museums and other organisations can use the date for skywatching, workshops, talks and science outreach activities. Schedules vary by city and organisation.
