ISRO is the Indian Space Research Organisation.

The objective of ISRO is to develop space technology and its application to various national tasks. Accordingly, Indian Space Research Organisation (ISRO) has successfully operationalised two major satellite systems namely Indian National Satellites (INSAT) for communication services and Indian Remote Sensing (IRS) satellites for management of natural resources; also, Polar Satellite Launch Vehicle (PSLV) for launching IRS type of satellites and Geostationary Satellite Launch Vehicle (GSLV) for launching INSAT type of satellites.

The Space Commission formulates the policies and oversees the implementation of the Indian space programme to promote the development and application of space science and technology for the socio-economic benefit of the country. DOS implements these programmes through, mainly Indian Space Research Organisation (ISRO), Physical Research Laboratory (PRL), National Atmospheric Research Laboratory (NARL), North Eastern-Space Applications Centre (NE-SAC) and Semi-Conductor Laboratory (SCL). The Antrix Corporation, established in 1992 as a government owned company, markets the space products and services.

JAXA is the Japan Aerospace Exploration Agency.

On October 1, 2003, the Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL) and the National Space Development Agency of Japan (NASDA) were merged into one independent administrative institution to be able to perform all their activities in the aerospace field as one organization, from basic research and development to utilization. The resulting independent administrative institution is the Japan Aerospace Exploration Agency (JAXA.)

JAXA proposed its long-term vision, "JAXA2025," to realize its own mission. Under thecorporate message "Reaching for the skies, exploring space," JAXA is pursuing various aerospace fields and is striving to succeed with various research and development missions.

Arianespace was founded in 1980 as the world’s first satellite launch company. Today, it has 21 shareholders from 10 European countries. Since its creation, Arianespace has launched with Ariane launchers 298 payloads, accounting for more than half of the commercial satellites now in service worldwide.

In 2010, the company had revenues of 897 M€. As of 1st July 2011, Arianespace had 332 employees, including 258 at the company’s headquarters in Evry, near Paris, 63 at the Guiana Space Center in French Guiana, launch site for Ariane 5, Soyuz and Vega, and 11 at local offices in Washington DC (United States), Tokyo (Japan) and Singapore.

Arianespace offers launch service & solutions to satellite operators from around the world, including both private companies and government agencies, based on a complete family of launchers:

• Ariane 5 heavy-lift launch vehicle, operated at the Guiana Space Center (60 launches, including 46 successful launches in a row),  
• Soyuz medium launcher, which has been operated at Baikonur since 1999 (23 commercial launches, all successful), and which, after the success of the first launch on 21 October 2011, is now being operated at the Guiana Space Center,
• Vega light launcher, which will be operated at the Guiana Space Center starting 2012.

 The technical performance of its launch vehicles and a substantial order book have made Arianespace the world leader in satellite launch services for the last few years (as of 2012), with a market share exceeding 50%.

The Meteosat series of satellites are geostationary meteorological satellites operated by the Euopean organisation EUMETSAT.

Soyuz  is a family of expendable launch systems developed by OKB-1, and manufactured by TsSKB-Progress in Samara, Russia. 

The launch services are commercialised by the company Starsem.

The Soyuz launch vehicle family has provided reliable and efficient launch services since the birth of the space program. Vehicles in this family, which have launched both the first satellite and first man into space, have been credited with more than 1000 launches. Today, this vehicle is used for manned and unmanned flights to the International Space Station and commercial launches.

SPOT (Satellite Pour l’Observation de la Terre, lit. "Satellite for Earth Observation") is a high-resolution, optical imaging Earth observation satellite system operating from space. It is run by Spot Image based in Toulouse, France. It was initiated by the CNES (Centre national d'études spatiales — the French space agency) in the 1970s.

The European remote sensing satellite (ERS) was the European Space Agency's first Earth-observing satellite, injected into a Sun-synchronous polar orbit at a height of 782–785 km.

ERS-1 and ERS–2 were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields.

ERS-2 added an additional sensor for atmospheric ozone monitoring. The two satellites acquired a combined data set extending over two decades.

The Landsat program is the longest running enterprise for acquisition of satellite imagery of Earth.

On July 23, 1972 the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. 

The most recent, Landsat 7, was launched on April 15, 1999. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the USA and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance, education and national security.
