Most countries do not publicly release regular reports on the size of their space workforce, making analysis of trends over time difficult or impossible. However, point assessments of the size or activities within these space nations still provide useful insight into the health of the global space...

Canadian SSA operations are conducted using two satellites: Sapphire and NEOSSat. The Canadian Department of National Defence (DND) uses Sapphire, which moves around the Earth in a sun-synchronous orbit to detect the reflections of other objects in space. It entered its five-year operational phase...

Year: 2015
In 2015, the ISS was the only inhabited space station orbiting the Earth. By July 2015, an international cadre of 220 men and women had temporarily lived aboard the ISS as builders, scientists, and explorers since people first entered the station in November 2000. The crew aboard the ISS continued...

While space has many practical applications that are already making real differences in people’s daily lives, many more research activities are still in the early stages of development. Depending on their maturity and complexity, the practical uses of these research avenues are not always well...

In spite of two failed launches that destroyed 34 of its satellites, Planet Labs still appears to be positive about its future. So much so that the Earth observation (EO) satellite manufacturer and operator announced its intention to acquire BlackBridge’s RapidEye, a Canadian Earth observation...

Direct-to-home (DTH) television is the transmission of television programming directly to end-user equipment. Other terms are direct broadcast and satellite television. The term broadcast service satellite (BSS) is often used to describe satellites offering these services. BSS satellites operate in...

GEO satellites provide coverage of a wide area from a relatively fixed position, making them ideal for broadcast applications to multiple downlink sites, as well as for networking services to widely dispersed corporate and government facilities. Video distribution, point-to-point video feeds, also...
Year: 2009
GEO satellites provide a wide fixed coverage area, making them ideal for reaching a community of stationary antennas that do not need to track a moving object in space. The dominant providers of international fixed satellite services (FSS) are Intelsat, SES, Eutelsat, and Telesat. These four...

The dominant providers of international fixed satellite services (FSS) are Intelsat, SES, Eutelsat, and Telesat. These four companies collectively own nearly half of all GEO commercial communications satellites (## satellites, or ##% of the total), and represented ##% of total FSS market revenues...
Year: 2011
GEO satellites provide a wide fixed coverage area, making them ideal for sending one signal to a large number of stationary antennas. There were ## fixed satellite services (FSS) satellites in orbit during 2011, providing DTH video, satellite radio, broadband internet, broadcast video distribution,...

To improve the resolution from ground-based observatories and to capture light from distant, dim objects, telescopes are growing larger. Due to the correspondingly large cost of construction and operation, these massive telescopes are often supported financially by multinational consortia.

Other national space agencies are also supporting key technology development efforts. In April 2011, ESA approved the development of Proba-3, a mission to demonstrate autonomous formation flying by spacecraft. Scheduled for launch in 2016, Proba-3 will feature two satellites that will fly in...

Once launched, satellites generally cannot be refueled or repaired. Satellites have lifetimes limited by the amount of propellant they can carry on board to maintain their orbits. A failure of a key system on a satellite can partially or totally disable the spacecraft, causing a disruption in...

Astronomers are laying the groundwork for a new generation of extraordinarily large observatories. The Square Kilometer Array (SKA) Telescope will be the world’s largest and most sensitive radio telescope ever built. The SKA takes its name from the combined size of the collecting area of the...

Much of the world depends on GEO satellites for defense, communication, science, and weather monitoring. These expensive assets eventually fail or run out of propellant, but refueling and maintaining them can extend their lives, giving their users more value. Servicing can also help make space more...
