SMART-1 was the first European Lunar mission and a technology demonstrator of Deep Space Electric Propulsion.

It was launched in October 2003, reached the moon observation orbit in 2005 and carried out lunar science experiment till controlled crash on the lunar surface in September 2006.

Skynet is a family of military satellites, now operated by Paradigm Secure Communications on behalf of the UK Ministry of Defence, which provide strategic communication services to the three branches of the British Armed Forces and to NATO forces engaged on coalition tasks.

Ziyuan 3 or ZY-3 (Chinese: 资源三号 meaning Resources 3) is a Chinese Earth observation satellite launched in January 2012. It is a high-resolution imaging satellite operated by the Ministry of Land and Resources of the People's Republic of China.

The Ziyuan 3 satellite was constructed by the China's Academy of Space Technology, and carries three cameras produced by the Changchun Institute of Optics, Fine Machinery and Physics. A camera aligned normal to the Earth's surface will produce images with a spectral resolution of 2.5 metres (8 ft 2 in), whilst the other two, offset at 22 degrees forward and aft, have spectral resolutions of 4.0 metres (13.1 ft). In addition to the three cameras, Ziyuan-3 carries an infrared multispectral spectrometer, with a spectral resolution of 6.0 metres (19.7 ft). The satellite is used to provide imagery to monitor resources, land use and ecology, and for use in urban planning and disaster management. It had a mass at launch of 2,630 kilograms (5,800 lb).

Ziyuan 3 was launched by a Long March 4B carrier rocket, flying from Launch Complex 9 at the Taiyuan Satellite Launch Centre. The launch occurred at 03:17 UTC on 9 January 2012, and was the first orbital launch of the year. VesselSat-2 was launched as a secondary payload on the same rocket.

The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program.

It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.

Astrotech Corporation, formerly Spacehab Inc., is an aerospace company headquartered in Austin, Texas, USA, which provides commercial space products and services (to NASA, the U.S. Department of Defense, etc.). 

The Company changed its name to Astrotech Corporation in 2009 to align the corporate name with the company's core business offering, Astrotech Space Operation. Astrotech Space Operations provides support necessary for government and commercial customers to process their satellite hardware for launch, including planning; construction and use of unique equipment and facilities; and spacecraft checkout, encapsulation, fueling, and transport. In its 29 year history, Astrotech has supported the processing of more than 290 spacecraft.

Antrix Corporation Limited is commercial wing of Indian Space Research Organization (ISRO). The name "Antrix" is an anglicized version of Antariksh, from the Sanskrit word for "space" or "sky".

Antrix Corporation Limited is a wholly owned Government of India Company under the administrative control of the Department of Space, Government of India. Antrix Corporation Limited was incorporated as a private limited company owned by Government of India, in September 1992 as a Marketing arm of Indian Space Research Organization (ISRO) for promotion and commercial exploitation of space products, technical consultancy services and transfer of technologies developed by ISRO. Another major objective is to facilitate development of space related industrial capabilities in India.

HYLAS (or HYLAS-1) is a British satellite in geostationary orbit.

HYLAS-1, which is an acronym for Highly Adaptable Satellite, is a communications satellite and was launched by the European Ariane 5 launch vehicle from the Guyana Space Centre at Kourou in French Guyana.

It is located at the orbital location of 33.5 degrees west and will provide communications services including High Definition Television (HDTV) and interactive satellite delivered broadband services.

The Hylas satellite operator is Avanti Communications.

OSCAR is an acronym for Orbiting Satellite Carrying Amateur Radio. OSCAR series amateur radio satellites use amateur radio frequency allocations to facilitate communication between amateur radio stations.

These satellites can be used for free by licensed amateur radio operators for voice (FM, SSB) and data communications (AX.25, packet radio,APRS). Currently over 20 fully operational satellites in orbit act as repeaters, linear transponders or store and forward digital relays.

Throughout the years OSCAR satellites have helped make breakthroughs in the science of satellite communications. A few advancements include the launch of the first satellite voice transponder (OSCAR 3) and the development of highly advanced digital "store-and-forward" messaging transponder techniques. To date, over 70 OSCARs have been launched with more to be launched in the future.
