World Space Week 2026 (October 4–10): Theme "Rocket Revolution" — Marking 69 Years Since Sputnik 1

Why in News

World Space Week 2026 begins today, October 4, running through October 10, 2026. The theme for 2026 is "Rocket Revolution" — celebrating the transformation of the global space launch industry through commercial launch providers, reusable rockets, and dramatically reduced access costs. The observance marks the 69th anniversary of Sputnik 1's launch (October 4, 1957, the first artificial satellite) and the 59th anniversary of the signing of the Outer Space Treaty (October 10, 1967).

Theme 2026: Rocket Revolution

The 2026 theme celebrates the radical democratisation of space access through the emergence of commercial launch providers and reusable rocket technology. The launch cost per kilogram to Low Earth Orbit (LEO) fell from ~$50,000 (Space Shuttle era) to under $3,000 today, primarily driven by reusability. Key developments in the "Rocket Revolution":

• Reusable first stages: Enable rapid turnaround and radical cost reduction
• New entrants: Commercial launch providers in the US, Europe, China, Japan, India (ISRO's SSLV and the emerging private launch sector via IN-SPACe)
• India's angle: ISRO's Small Satellite Launch Vehicle (SSLV), the Next Generation Launch Vehicle (NGLV) under development, and private Indian launch startups (Agnikul Cosmos, Skyroot Aerospace) represent India's entry into the commercial rocket revolution.

The Outer Space Treaty (OST), 1967 — Key Provisions

The Outer Space Treaty is the foundational international law document for all space activities. India is a signatory. Key provisions:

• Article I: Outer space is the "province of all mankind" — exploration and use for the benefit of all countries.
• Article II: Outer space, including the Moon and celestial bodies, is NOT subject to national appropriation by sovereignty, use, or occupation. No country can "own" outer space or the Moon.
• Article III: States must conduct activities in conformity with international law, including the UN Charter.
• Article IV: Prohibition on nuclear weapons and other WMDs in orbit, on celestial bodies, or in outer space. The Moon and celestial bodies must be used for peaceful purposes only.
• Article VI: States bear international responsibility for national space activities, whether carried out by government or non-governmental entities (companies, startups). This is why India needs IN-SPACe for authorising private launches.
• Article VII: Launching State is liable for damage caused by its space objects.
• Article IX: Principle of "harmful contamination avoidance" — states must avoid adverse changes to Earth's environment and contamination of celestial bodies.

UNOOSA and India

The United Nations Office for Outer Space Affairs (UNOOSA), headquartered in Vienna, administers the UN Programme on Space Applications and maintains the UN Register of Objects Launched into Outer Space (under the Registration Convention). India regularly registers its satellite launches with UNOOSA. ISRO collaborates with UNOOSA through the UN-SPIDER (Platform for Space-based Information for Disaster Management and Emergency Response) programme — providing Earth observation and satellite communication services during natural disasters, including to neighbouring countries under India's development cooperation framework.

Answer: (B)
2. Q. Under the Outer Space Treaty, 1967, which of the following is/are prohibited? 1. Nuclear weapons in orbit 2. National appropriation of the Moon by any State 3.

FAQ

Why is World Space Week observed from October 4 to 10?

October 4 marks the 1957 launch of Sputnik 1 (world's first artificial satellite) and October 10 marks the 1967 signing of the Outer Space Treaty — two of the most significant events in the history of space exploration and space law. The UN General Assembly proclaimed World Space Week in 1999.

What is the theme of World Space Week 2026?

"Rocket Revolution" — focusing on commercial launch vehicles, reusable rockets, and how dramatically lower launch costs are transforming access to space for governments, startups, and researchers worldwide.

What does the Outer Space Treaty say about ownership of the Moon?

Article II of the Outer Space Treaty explicitly prohibits national appropriation of the Moon, other celestial bodies, or outer space itself by claim of sovereignty, use, or occupation. No country or company can legally "own" the Moon under the OST. However, the more specific Moon Agreement (1979) — which would designate the Moon's resources as "common heritage of mankind" — has not been ratified by any major spacefaring nation.
