Space agencies in the world represent humanity’s collective ambition to explore the cosmos — and their budgets, missions, and milestones are a recurring topic in UPSC Prelims, SSC CGL, Banking, and General Awareness sections of all major competitive exams.
From NASA’s Moon landings to ESA’s Rosetta comet mission, CNSA’s Tiangong space station, and ISRO’s record-breaking achievements, this page gives you a complete, updated list of the world’s most important space agencies with their headquarters, founding years, key missions, and exam-critical facts for confident, focused revision.
⚡ Quick Facts
- NASA (USA), established in 1958, is the world’s largest and most funded space agency — responsible for Apollo Moon landings and the Hubble Space Telescope.
- Roscosmos (Russia) launched the world’s first satellite (Sputnik-1, 1957) and sent the first human to space (Yuri Gagarin, 1961).
- ESA (European Space Agency), established in 1975, is the collective space agency of 22 European nations — headquartered in Paris, France.
- CNSA (China) launched its first astronaut in 2003 and operates the Tiangong space station — making China the 3rd country to independently send humans to space.
- ISRO (India), established in 1969, is the world’s most cost-effective space agency — famous for Chandrayaan-3’s lunar south pole landing (2023).
Only 3 countries have independently sent humans to space (with their own rockets): Russia (1961), USA (1962), China (2003). India (Gaganyaan) will be the 4th — but has not yet done so. ESA has 22 member states — NOT 27 (don’t confuse with the EU). Luna-25 (Russia, 2023) crashed — India’s Chandrayaan-3 succeeded. The UAE’s Hope Mission was the Arab world’s first Mars mission — it orbited Mars but did NOT land. And Roscosmos was established in 1992 — the Soviet space programme goes back to 1955.

SpaceX (founded by Elon Musk, 2002) transformed the global space industry: first private company to reach the ISS (2012), first reusable orbital rocket (Falcon 9, 2015 landing), Starlink constellation (6,000+ LEO satellites for broadband), Crew Dragon transporting NASA astronauts since 2020, and Starship — the world’s most powerful rocket for Moon/Mars missions. SpaceX’s model inspired India’s IN-SPACe framework and Indian private startups (Skyroot Aerospace, Agnikul Cosmos).

The USSR (Soviet Union) launched Sputnik-1, the world’s first artificial satellite, on 4 October 1957. This marked the beginning of the Space Age and triggered the Space Race between the USA and USSR. The word “Sputnik” means “fellow traveller” or “satellite” in Russian. The USA’s Explorer-1 followed in January 1958.
The UAE successfully launched the Hope Mars Mission (Al-Amal) in 2020, which entered Mars orbit in February 2021 — the Arab world’s first successful interplanetary mission. It was developed by the Mohammed Bin Rashid Space Centre (MBRSC) in Dubai and launched on a Japanese H-IIA rocket. Note: it orbited Mars — it did NOT land.
Only 3 countries have independently launched humans into space using their own rockets — the USSR/Russia (Yuri Gagarin, 1961), the USA (John Glenn orbit, 1962), and China (Yang Liwei, 2003). India is working on becoming the 4th with Gaganyaan (planned 2025–26). Other nations’ astronauts have flown to space, but on Russian or American rockets.
The European Space Agency (ESA) is headquartered in Paris, France. As of 2026, ESA has 22 member states — note that ESA membership is not the same as EU membership. ESA’s main technical facility is ESTEC in Noordwijk, Netherlands, and its launches are conducted from the Guiana Space Centre in Kourou, French Guiana, near the equator.
SpaceX’s Starlink is a global satellite internet constellation — over 6,000 low Earth orbit satellites providing high-speed broadband internet. It is separate from Crew Dragon (ISS crew transport), Starship (deep space vehicle), and Starship’s HLS variant (NASA Artemis lunar lander). Starlink has also been used in conflict zones (Ukraine) as a communications lifeline.

❓ Frequently Asked Questions
NASA (National Aeronautics and Space Administration) of the United States is generally the world’s largest and most funded space agency, with an annual budget of approximately $25 billion. Established on 29 July 1958 in response to the Soviet Sputnik launch, NASA’s achievements include the Apollo Moon landings (1969–1972), the Hubble Space Telescope, Mars rovers Curiosity and Perseverance, the ISS partnership, and the ongoing Artemis programme aimed at returning humans to the Moon and eventually Mars.
Key milestones include: Sputnik-1 (USSR, 1957) as the first artificial satellite; Yuri Gagarin (USSR, 12 April 1961) as the first human in space; Neil Armstrong and Buzz Aldrin (USA, 20 July 1969) on the Moon; the ISS beginning continuous habitation in November 2000; China’s Yang Liwei in 2003; SpaceX Crew Dragon (2020) as the first private ISS crew mission; the UAE’s Hope Mars orbiter (2021); India’s Chandrayaan-3 south pole Moon landing (23 August 2023); and the NASA Artemis programme targeting Moon return in the mid-2020s.
The International Space Station (ISS) is a modular space station in low Earth orbit at approximately 400 km altitude. It has been continuously inhabited by rotating crews since 2 November 2000 — the longest-running crewed space habitat in history. The ISS is a joint project of five agencies: NASA (USA), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). It serves as a research laboratory for microgravity science, medicine, astronomy, and Earth observation. The ISS is expected to be deorbited around 2030, with NASA planning to hand over low Earth orbit habitation to commercial stations.
Space agencies are tested in UPSC Prelims (Science & Technology, International Relations, Current Affairs), SSC CGL, Banking General Awareness, Defence exams (NDA, CDS), and all State PSC papers. Key tested facts: first satellite (Sputnik-1, USSR, 1957), first human (Gagarin, USSR, 1961), first Moon landing (Apollo 11, NASA, 1969), 3 countries with independent human spaceflight (Russia, USA, China), ESA’s member count and HQ (Paris, 22 members), JAXA’s Hayabusa mission, CNSA’s Tiangong space station, UAE’s Hope Mars Mission, SpaceX’s commercial revolution (reusable rockets, Starlink, Crew Dragon), and ISRO’s recent achievements (Chandrayaan-3, 2023). The ongoing Artemis programme and the China-Russia ILRS rival Moon base are the highest-priority current affairs topics.
