Indian Space Research Organization, formed in 1969, superseded the erstwhile INCOSPAR. Vikram Sarabhai, having identified the role and importance of space technology in a Nation’s development. ISRO maintains one of the largest fleet of communication satellites (INSAT) and remote sensing (IRS) satellites, that cater to the ever growing demand for fast and reliable communication and earth observation respectively. ISRO develops and delivers application specific satellite products and tools to the Nation.Presently it has totally around 14000 employees including scientist specialist and technical staffs. The annual budget of the organization is around 17000 billion Indian rupees. Which make 7th largest space organization in the world.

The National Aeronautics and Space Administration NASA is an independent agency of the U.S. federal government responsible for the civilian space program, as well as aeronautics and space research.

NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA). The new agency was to have a distinctly civilian orientation, encouraging peaceful applications in space science. Since its establishment, most US space exploration efforts have been led by NASA, including the Apollo Moon landing missions, the Skylab space station, and later the space shuttle. These the most famous space organization in the world, which made first human landing in moon and unmanned space landings in mars which was master minded by one of the most space scientist in the world-warner won brown.

The Japan Aerospace Exploration Agency (JAXA) National Research and Development Agency on Aerospace Research and Development”) is the Japanese national aerospace and space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and launch of satellites into orbit, and is involved in many more advanced missions such as asteroid exploration and possible human exploration of the Moon.

The Roscosmos State Corporation for Space Activities commonly known as Roscosmos (Russian: Роскосмос), is a state corporation of the Russian Federation responsible for space flights, cosmonautics programs, and aerospace research. Originating from the Soviet space program founded in the 1950s, As the main successor to the Soviet space program, Roscosmos’ legacy includes the world’s first satellite, first human spaceflight, and first space station. Its current activities include the International Space Station, wherein it is a major partner. On February 22, 2019, Roscosmos announced the construction of its new headquarters in Moscow, the National Space Centre.

CNSA is an agency created in 1993 when the Ministry of Aerospace Industry was split into CNSA and the China Aerospace Science and Technology Corporation (CASC). The former was to be responsible for policy, while the latter was to be responsible for execution. This arrangement proved somewhat unsatisfactory, as these two agencies were, in effect, one large agency, sharing both personnel and management.[2]
As part of a massive restructuring in 1998, CASC was split into a number of smaller state-owned companies. The intention appeared to have been to create a system similar to that characteristic of Western defense procurement in which entities which are government agencies, setting operational policy, would then contract out their operational requirements to entities which were government-owned, but not government-managed.

Envisioned to fulfill the requirements of scientists and engineers in the Indian Space Program, by offering undergraduate and postgraduate education and research programmes in space science and technology, the institute started functioning from the Vikram Sarabhai Space Centre (VSSC) campus, Thiruvananthapuram, on 14 September 2007 with an initial investment of ₹270 crore (equivalent to 656 crore or US$92 million in 2019) and annual recurring cost of ₹40 crore (US$5.6 million) by the Department of Space.[7] It is the only institute of its kind in India, which offers a BTech degree in Space Technology, and subjects exclusive to the arena of space science and technology. B. N. Suresh, former director of Vikram Sarabhai Space Centre, is the founding director of the institute.

On 14 July 2008, the Union Human Resource Development Ministry, on the advice of the University Grants Commission (UGC), conferred deemed university status, under a new category, to the institute for a period of five years.

The European Space Agency (ESA; French: Agence spatiale européenne pronunciation ASE; German: Europäische Weltraumorganisation) is an intergovernmental organisation of 22 member states dedicated to the exploration of space. Established in 1975 and headquartered in Paris, ESA has a worldwide staff of about 2,200 in 2018 and an annual budget of about €6.68 billion (~US$7.43 billion) in 2020.

ESA’s space flight programme includes human spaceflight (mainly through participation in the International Space Station program); the launch and operation of uncrewed exploration missions to other planets and the Moon; Earth observation, science and telecommunication; designing launch vehicles; and maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle. The agency is also working with NASA to manufacture the Orion Spacecraft service module that will fly on the Space Launch System.

Space Exploration Technologies Corp. (SpaceX) is an American aerospace manufacturer and space transportation services company incorporated in Delaware and headquartered in Hawthorne, California. It was founded in 2002 by Elon Musk with the goal of reducing space transportation costs to enable the colonization of Mars. SpaceX’s achievements include the first privately funded liquid-propellant rocket to reach orbit (Falcon 1 in 2008), the first private company to successfully launch, orbit, and recover a spacecraft (Dragon in 2010), the first private company to send a spacecraft to the International Space Station (Dragon in 2012), the first vertical take-off and vertical propulsive landing for an orbital rocket (Falcon 9 in 2015), the first reuse of an orbital rocket (Falcon 9 in 2017), the first to launch a private spacecraft into orbit around the Sun (Falcon Heavy’s payload of a Tesla Roadster in 2018), and the first private company to send astronauts to orbit and to the International Space Station (SpaceX Crew Dragon Demo-2 and SpaceX Crew-1 missions in 2020).

The Australian Space Agency is Australia’s national agency responsible for the development of Australia’s commercial space industry, coordinating domestic activities, identifying opportunities and facilitating international space engagement that include Australian stakeholders. Its headquarters are located in Adelaide, the southeastern capital city of South Australia. As of 2008, Australia was the only Organisation for Economic Co-operation and Development (OECD) country without a space agency other than Iceland, with the preceding National Space Program and Australian Space Office (ASO) having been disbanded by the federal government in 1996. A government report from the Australian Senate Standing Committee on Economics noted that Australia was “missing out on opportunities” and recommended that an agency immediately be developed.

In 2009, the Space Policy Unit funded the Australian Space Research Program over three years.

On 16 September 2016, Andrea Boyd, an Australian working as a flight operations engineer for the International Space Station (ISS) in Cologne, Germany, delivered an address at the Global Access Partners Summit in Parliament House, Sydney, urging Australia to grasp the commercial opportunities of the new space market and protect its national sovereignty by establishing a national space agency. In response, Australian policy institute Global Access Partners created a taskforce including Andrea Boyd, former astronauts Dr Andy Thomas AO and Prof Gregory Chamitoff, as well as Australian and international scientists, entrepreneurs, innovators, financial analysts and legal experts. The taskforce was chaired by Dr Jason Held, founder of Saber Astronautics. The taskforce, co-funded by the federal Department of Industry, Innovation and Science, advocated the creation of a commercially focused Australian space agency and delivered its report to the Australian Government in August 2017.

Hindustan Aeronautics Limited (HAL) is an Indian state-owned aerospace and defence company headquartered in Bangalore (Bengaluru), India. It is governed under the management of the Indian Ministry of Defence.
