Two low Earth orbiting Canadian satellites, Sapphire and NEOSSat, provided spaceborne space situational awareness (SSA) for Canada during 2016. While they are both SSA satellites, they fulfill different SSA missions. Sapphire, a Canadian Department of National Defence (DND) satellite launched in 2013, is a part of the Canadian Space…
During 2016, the International Space Station (ISS) continued to be the primary inhabited space laboratory orbiting the Earth. An international contingent of scientists, engineers, and researchers used the ISS for various microgravity-based experiments.
One ISS program, NASA’s human research One-Year Mission, required astronaut…
When overhead space assets show the impacts of mining on the environment.
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 understood or guaranteed.
Government space programs accounted for approximately $## billion in spending during 2013, representing ##% of the global space economy. Government investment in space decreased by ##% in 2013, contributing to a cumulative average annual growth rate of ##% between 2009 and 2013. The top-line figures, however, do not fully depict how some countries have significantly increased space spending while others have made cuts, as shown in Exhibit 2n. Because not all governments operate under the same fiscal cycle, international space spending numbers were derived from the most recent budgetary information available for each country. The figures reported in the following country profiles are presented in both the local currency and U.S. dollars as of June 30 of the appropriate year.

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 thousands of individual dishes that comprise it, making it far more sensitive than any existing radio telescope.
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 sustainable because broken and drifting satellites take up valuable real estate in GEO and pose a risk to neighboring systems.
The largest in-space platform ever constructed is the International Space Station (ISS). “Led by the United States, the ISS draws upon the scientific and technological resources of 16 nations: Canada, Japan, Russia, 11 nations of the European Space Agency [Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland, and the United Kingdom], and Brazil,” according to NASA.
