World Space Week 2026 History

The history of World Space Week is linked with two major milestones that shaped modern space exploration and international space governance.

• United Nations declaration: On December 6, 1999, the United Nations General Assembly adopted resolution 54/68 and declared October 4 to 10 as World Space Week.
• Sputnik 1 launch: On October 4, 1957, Sputnik 1 became the first human made Earth satellite to be launched into outer space. Its launch opened a new era of space exploration.
• Outer Space Treaty: On October 10, 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.
• United Nations’ Role: The United Nations recognised outer space as a new dimension of human activity and promoted its peaceful use. Resolution 1348 (XIII) was its first resolution related to outer space.
• International Coordination: At least 25 United Nations entities and the World Bank Group routinely use space applications. The Inter Agency Meeting on Outer Space Activities supports coordination across the UN system.
• UNOOSA Role: The United Nations Office for Outer Space Affairs promotes international cooperation in peaceful space activities. It also serves as the secretariat for COPUOS and maintains the United Nations Register of Objects Launched into Outer Space.

Sputnik 1

Sputnik 1 was the first human made satellite to orbit Earth, marking the beginning of the Space Age and a major milestone in space exploration.

• Launch and significance: Sputnik 1 was launched by the Soviet Union on October 4, 1957, from Gagarin’s Start at Tyuratam. Its launch began the Space Age and the Space Race.
• First artificial satellite: Officially designated Satellite 1, Sputnik 1 became the first artificial satellite to successfully enter Earth’s orbit and demonstrated that objects could be placed into orbit.
• Design and signals: Sputnik 1 was a polished aluminium alloy sphere with four external radio antennas. Its radio transmitters sent signals on two frequencies that could be monitored worldwide.
• Orbital operation: The satellite completed one Earth revolution in about 96 minutes. It continued orbiting after its radio batteries were exhausted and completed 1,440 orbits before re-entering the atmosphere on January 4, 1958.
• Scientific objectives: Sputnik 1 helped study atmospheric density, radio signal propagation and orbital tracking. Its orbital decay and radio signals provided useful information about the upper atmosphere and ionosphere.
• Global impact: The successful launch surprised the world and accelerated the Space Race. It also demonstrated the space launch potential of the R 7 rocket, supporting later Soviet lunar and human spaceflight missions.

Space Sector in India

India’s space sector has expanded from a government led system into a broader ecosystem involving public institutions, private companies and international partnerships.

• Early foundation: India’s space journey began with Aryabhata in 1975. The satellite was launched by the Soviet Union and marked India’s first satellite mission.
• Private participation: India opened the space sector to private participation in 2020. The Indian Space Policy 2023 further expanded private involvement across the space value chain.
• FDI reforms: Foreign investment rules were liberalised in February 2024. Up to 100% investment was permitted in satellite component manufacturing activities.
• Launch vehicles: India has operationalised PSLV, GSLV, GSLV Mk III and SSLV. These vehicles support Earth observation, communication, navigation, scientific, exploration and commercial missions.
