Government space agencies are established by governments of countries or regional groupings of countries to establish a means for advocating for and/or engaging in activities related to outer space, exploitation of space systems, and space exploration. The listings summarize all countries and regional authorities that have established space agencies. The listings established a comparative summary of demonstrated capabilities across the countries that have invested in the pursuit of space-based objectives.
The space agency listings are segregated to enable identification of subsets of the complete list that have advanced to higher levels or technical or programmatic proficiency in accordance with the following:
Establishment of agency, initial exploitation of space-based systems
Development of launch capability
Capacity for extraterrestrial exploration
Demonstration of human spaceflight capability across one or more of these domains
The four listings identify a technological progression in complexity and capacity that historically aligned to the developments that occurred during the 20th century space race between the United States and the Soviet Union. It is not intended to offer that this is the only path to advanced space faring status; variations and adaptations are expected and are likely to occur based on the technological capabilities that are available to today as opposed to 50 or more years ago.
For each identified "Demonstrated capability" a reference is included to that program's first demonstration of the technical capacity or capability to meet the defined objective.
The fifth listing identifies countries that are considering or are developing space agency organizations but have not ratified formation or operation as of yet.
Note as well that the demonstrated capabilities represent the national (or regional) capacity to achieve the identified objective. These listings do not attempt to determine which programs were uniquely or solely funded by the space agency itself.
For each listing, the short name or acronym identified is the English version, with the native language version below. The date of the founding of the space agency is the date of first operations where applicable. If the space agency is no longer running, then the date when it was terminated. Additionally, the strategic nature of many space programs result in cooperation between civil agency and military organizations to meet unique staff and technical proficiencies required to support space programs given the geographic expanse required to ensure successful operation.
List of space agencies
As of 2024,[update] 74 different government space agencies are in existence, including 68 national space agencies and six international agencies. Initial competencies demonstrated include funding and nomination of a candidate to serve as astronaut, cosmonaut, or taikonaut with the countries/organizations executing human spaceflight solutions. Other demonstrated capabilities include operation of a satellite (e.g. a communications or remote sensing system) largely developed and/or delivered by a third party, domestic development of a satellite system, and capacity to recover a science payload from a sub-orbital or orbital mission. Seven space agencies (six national, one international) have demonstrated all four of those capabilities.
Agenzia Spaziale Italiana (ASI) British National Space Centre (BNSC) Canadian Space Agency (CSA) Centre National d’Études Spatiales (CNES) China National Space Administration (CNSA) Deutsches Zentrum für Luft und Raumfahrt (DLR) European Space Agency (ESA) Instituto Nacional de Pesquisas Espaciais (INPE) Japan Aerospace Exploration Agency (JAXA) National Aeronautics and Space Administration (NASA) Russian Federal Space Agency (RFSA)

This group of agencies have developed or are developing launch infrastructure including space launch sites, suborbital launch technology, orbital launch systems, and reusable hardware technologies.
List of space agencies with extraterrestrial exploration capability
This group of agencies have developed advanced technological capabilities required for travel and study of other heavenly bodies within the Solar System. These involve the capacity to leave the local area around the planet Earth for lunar and/or missions to other bodies in the Solar System. As of February 2023, six (6) countries/agencies have achieved objectives necessary to be listed here.
Overview of space agencies extraterrestrial exploration capability
This small group of countries/space agencies have demonstrated the highest technological capacity with systems and solutions that support human spaceflight along with the ancillary technological capabilities to support human activity in orbit and/or on extraterrestrial bodies. The missions identified (and personnel when appropriate) are the first successful accomplishments of each activity.
Overview of space agencies human spaceflight capability
Proposed in 2015. AU plans to launch the agency by 2019 with a proposed headquarter in Cairo, Egypt. Funded by Egypt. See the stamp issued by Egypt on 19 September 2019.[125][126][127][128][129]
Proposed in 2013 with the goal to launch satellites. Negotiating with the International Telecommunication Union to clear the path for its prospective launch.[131]
Proposed in 2009. Immediate goal was to construct and launch two satellites. Sri Lankan Telecommunications Regulatory Commission had signed an agreement with Surrey Satellite Technology Ltd to get the relevant help and resources.[162]
The annual budgets listed are the official budgets of national space agencies available in public domain. The budgets are not normalized to the expenses of space research in different countries, i.e. higher budget does not necessarily mean more activity or better performance in space exploration.[166][167] Budget could be used for different projects: e.g. GPS is maintained from the US defence budget,[168] whereas ESA's money is used for developing the European Galileo positioning system.[169] For European contributors to ESA, the national budgets shown include also their contributions to ESA.
Five government space agencies, the United States (NASA), China (CNSA), France (CNES), Japan (JAXA) and Russia (Roscosmos), have annual budgets of more than two billion US dollars.
