World Space Week 2026

World Space Week 2026

World Space Week 2026 explores how reusable rockets, new launch vehicles and commercial spaceflight are transforming access to space.

Getting to space is no longer just a matter of building a rocket and launching it once. Reusable boosters, new launch vehicles and a growing commercial space industry are reshaping the path to orbit — a transformation that will take center stage during this year's World Space Week.

World Space Week (WSW) 2026 runs from Oct. 4 through Oct. 10, with this year's theme, "Rocket Revolution," highlighting the technologies and organizations changing how humanity reaches and uses space. The global celebration brings together space agencies, companies, educators, students, museums, astronomy clubs and space enthusiasts for events and activities around the world.

The annual celebration of WSW is tied to two important milestones in spaceflight history. Oct. 4 marks the anniversary of the 1957 launch of Sputnik 1, the first artificial satellite to orbit Earth, while Oct. 10 marks the signing of the Outer Space Treaty in 1967, which established principles for the peaceful exploration and use of outer space. The United Nations General Assembly established WSW as an annual observance in 1999.

In 1999, the United Nations started observing World Space Week – from October 4 to 10 – to celebrate the contribution of space technology for the benefit of humanity. Schools, space agencies, museums and astronomy clubs around the world hold stargazing nights, science classes, exhibitions and talks by astronauts and scientists.

Today, more than 80 countries have put satellites into orbit, and people from over 50 of those have travelled to space.

In this visual explainer, Al Jazeera looks at which countries have done so, how many space travellers have been women, and what comes next for human spaceflight.

On April 12, 1961, Soviet astronaut Yuri Gagarin became the first human in space.

On board the Vostok 1 spacecraft, he completed one orbit of Earth at about 27,400km/h (17,025mph) during a 108-minute flight. He later ejected from the spacecraft and landed by parachute.

The mission demonstrated that humans could survive launch, weightlessness and re-entry, giving the Soviet Union a major early victory in the Cold War Space Race.

Six years later, on October 10, 1967, the Outer Space Treaty entered into force. Signed by the US, the United Kingdom and the Soviet Union, it established that space should be explored and used peacefully and that no country could claim it as territory.

Less than two years later, NASA’s Apollo 11 mission landed the first humans on the moon. On July 20, 1969, Neil Armstrong became the first person to walk on its surface.

There is no single agreed boundary for where space begins: most international bodies use the Karman line, 100km (62 miles) above Earth, while the US military, NASA and the Federal Aviation Administration count anyone who flies above 80km (50 miles).

This year's theme "recognizes how increased space access and falling launch prices have stimulated the space ecosystem and exciting new space applications," Dennis Stone, WSW Association president, said in a statement from the organization, adding that the theme is also intended to inspire student interest in science, technology, engineering and mathematics, or STEM.

For decades, reaching orbit required enormous amounts of hardware, fuel and infrastructure — and rockets were generally designed to fly only once. That model has increasingly begun to change.

Reusable rockets have demonstrated that portions of a launch vehicle can return to Earth and fly again, while a growing number of commercial companies and countries are developing new ways to put satellites, spacecraft and other payloads into orbit.

The change is about more than simply building bigger or more powerful rockets. Reusability and new launch architectures could alter the economics and cadence of spaceflight, while smaller launch vehicles are opening additional options for organizations looking to send spacecraft into orbit.

The result is a space industry with more participants and a wider range of missions — from communications and Earth-observation satellites to scientific spacecraft and human spaceflight. Just last month, SpaceX's Starship reached orbit for the first time during its Sept. 28 test flight, successfully deploying 26 Starlink V3 satellites in a major milestone for the vehicle's development. The mission was ultimately cut short after an engine issue, but achieved its primary objectives of reaching orbit and deploying its payload.

More frequent and diverse access to orbit supports an expanding ecosystem of satellites and spacecraft that already plays a role in everyday life. Space-based systems provide communications, navigation, weather information and Earth-observation data, while satellites are increasingly used for environmental monitoring, disaster response and connectivity. That broader impact is part of what WSW aims to highlight.

This year's rocket theme also comes with educational resources designed to bring the subject into classrooms and homes. Estes Education partnered with WSW to develop a Rocket Revolution Toolkit, with activities for classrooms, families and clubs that encourage students to explore rocket science and engineering — including the challenges of designing reusable launch vehicles, according to a statement.

WSW events are expected to take place across 100 nations this week, with activities ranging from talks and exhibitions to classroom activities, movie nights, astronomy events and hands-on STEM projects.

Among the activities planned for 2026 are events from major space organizations and companies. The European Space Agency (ESA) and The Pokémon Company International are teaming up on a Europe-wide space-themed exhibition and Pokémon GO event, while the Kennedy Space Center Visitor Complex in Florida will host a WSW Expo on Oct. 9 featuring NASA and industry partners.

The rocket theme will also take a hands-on approach, with students and rocket clubs encouraged to launch model rockets using equipment provided by United Launch Alliance and Estes. The BBC StoryWorks Commercial Productions will also launch an exclusive online "Space Renaissance" event, featuring the world premiere of the series' first film and a discussion on how storytelling can bring space closer to global audiences. A full list of events, both local and virtual, can be found online.

For those who can't make it to an organized event, the night sky offers plenty of ways to mark the week, with Saturn at opposition on Oct. 4, the moon near Mars on Oct. 5, the moon near Jupiter on Oct. 6, the Draconid meteor shower peaking around Oct. 8-9, and a New Moon on Oct. 10.

So while "Rocket Revolution" is focused on the technology carrying humanity beyond Earth, celebrating WSW doesn't require a launchpad, a laboratory or even a telescope — you can simply step outside after dark. Be sure to check back here over the coming days for our WSW coverage of global events.

From 1999 rocket launches to planetary discoveries, celebrate decades of advancement in spaceflight during World Space Week 2026.The annual event recently kicked off in October and will last for a few more days, with a bevy of events planned in not just the United States, but around the world.While the weeklong extravaganza occurs every October, this year's celebration couldn't come at a better time.In 2026 alone, humans ventured toward the moon for the first time in half a century, while the world's largest rocket finally made it to orbit after three years of testing. In the years ahead, we could see humans land not just on the moon, but on Mars and potentially see breakthroughs in the search for habitable planets as new telescopes rove the cosmos.World Space Week, started in 1999 by the United Nations, is an annual weeklong international event recognizing advancements in space science and technology.This year, space week is scheduled to last between Sunday, Oct. 4, and Saturday, Oct. 10, accordingCoordinated by the nonprofit World Space Week Association, the celebration features numerous space-related STEM-themed events around the world, many hosted by government space agencies like NASA and aerospace companies. In 2025, for instance, 50,000 events were hosted in 102 countries, the association said.

This year's space week celebration comes as rocket launches are surging across the United States. The need for satellite deliveries and NASA's push to return astronauts to the moon under its Artemis program are both major reasons why the need for launch providers is increasing.

President Donald Trump, meanwhile, is calling for the development of more launch sites across the U.S., as well as upgrades to existing spaceports where rockets already lift off, in order to support 1,000 launches per year. Meeting the ambitious benchmark would mean that launches would more than quadruple from today, when about 200 rockets get off the ground per year.

Today, orbital rocket launches in the U.S. take place in Florida, Texas and California – all coastal states where rockets can fly over open water rather than populated cities.

That projected rise in launches is a big reason why this year's World Space Week's theme is "rocket revolution," according to organizers. No longer is orbit only the realm of major space agencies and larger aerospace contractors; these days, even smaller spaceflight startups can send spacecraft to Earth orbit – and beyond.

“It recognizes how increased space access and falling launch prices have stimulated the space ecosystem and exciting new space applications,” Dennis Stone, president of the World Space Week Association, said in a statement.

Spaceflight has come a long way since the dawn of the space age in the 1960s, when rockets were generally designed to fly just one time. These days, SpaceX's pioneering method to recover and reuse rocket boosters has not only made manufacturing spacecraft cheaper, but has also led

SpaceX, which tech mogul Elon Musk founded in 2002, is also developing its Starship rocket to be the first fully reusable launch vehicle – meaning both the booster and upper-stage that flies in space can fly multiple times. At the end of September, Starship – the world's largest rocket, at more than 400 feet tall – reached orbit for the first time.

The collaboration not only features a Pokémon space-themed exhibition and Pokémon GO event in Europe, but saw ESA astronaut Sophie Adenot take a Pikachu plush to the International Space Station. Adenot, in fact, is on her way back home as of Oct. 7 after departing the ISS with the rest of the Crew-12 mission.

By resolution 54/68 of 6 December 1999, the General Assembly proclaimed World Space Week, to celebrate the contributions of space science and technology to the betterment of the human condition.

World Space Week is the largest annual space event in the world. It 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 on all humanity further, by using a uniform theme globally.

For World Space Week 2026, celebrated globally from October 4 to 10, the theme is “Rocket Revolution.”Rocket Revolution focuses on the rapid transformation of space launch. 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. This shift is changing who can reach space, how often launches happen, and what space is used for.On 4 October 1957, the launch into outer space of the first human-made Earth satellite, Sputnik 1, opened the way for space exploration. A decade later, on 10 October 1967, the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies entered into force.Space science and technology and their applications are increasingly being used to support a wide range of United Nations activities. At least 25 United Nations entities and the World Bank Group routinely use space applications. They make important and sometimes essential contributions to the work of the United Nations, including in the implementation of recommendations of major world conferences and those of the Third United Nations Conference on the Exploration and Peaceful Uses of Outer Space (UNISPACE III), as well as support towards sustainable development.As a consequence, coordination, cooperation and synergy are essential for those activities to be effectively carried out by the United Nations system. The annual sessions of the Inter-Agency Meeting on Outer Space Activities are the main means of achieving that synergy. The effectiveness of the Meeting has been further enhanced by the holding, since 2004, of an open informal session immediately after the end of the Meeting, as a means of engaging Member States, in a direct and informal setting, in important space-related developments in the United Nations system. The agenda of the Inter-Agency Meeting is reviewed at each session and adapted to current operational needs.

From the very beginning of the Space Age, the United Nations recognized that outer space added a new dimension to humanity's existence. The United Nations family strives continuously to utilize the unique benefits of outer space for the betterment of all humankind.Recognizing the common interest of humankind in outer space and seeking to answer questions on how outer space can help benefit the people's of Earth, the General Assembly adopted its first resolution related to outer space, resolution 1348 (XIII) entitled "Question of the Peaceful Use of Outer Space".

On 10 October 1967, the "Magna Carta of Space", also known as the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies entered into force.

Today, the United Nations Office for Outer Space Affairs (UNOOSA) is the United Nations office responsible for promoting international cooperation in the peaceful uses of outer space. UNOOSA serves as the secretariat for the General Assembly's only committee dealing exclusively with international cooperation in the peaceful uses of outer space: the United Nations Committee on the Peaceful Uses of Outer Space(COPUOS).UNOOSA is also responsible for implementing the Secretary-General's responsibilities under international space law and maintaining the United Nations Register of Objects Launched into Outer Space.

The United Nations Office for Outer Space Affairs (UNOOSA) works to promote international cooperation in the peaceful use and exploration of space, and in the utilisation of space science and technology for sustainable economic and social development. The Office assists any United Nations Member States to establish legal and regulatory frameworks to govern space activities and strengthens the capacity of developing countries to use space science technology and applications for development by helping to integrate space capabilities into national development programmes.On 4 October 1957 the first human-made Earth satellite Sputnik I was launched into outer space, thus opening the way for space exploration. On 12 April 1961, Yuri Gagarin became the first human to orbit the Earth, opening a new chapter of human endeavour in outer space. The race to conquer space in the 21st century has changed significantly, allowing countries such as China, India, Japan, and the European Union, to enter the space race.International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
