Ranchers and space technology work together to herd cattle.
Year: 2005
Data communications services include very small aperture terminal (VSAT) services, Internet backhaul, direct-to-home broadband, and mobile data.
Year: 2011
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.
Year: 2012
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...
Year: 2013
Dedicated and secure communications links are vital to defense agencies around the world. Increasing demand for capacity—particularly secure connectivity using non-commercial frequency bands—has driven the deployment of dedicated military communications satellites. The U.S. military buys a...

Ground stations are an essential but often overlooked segment of space infrastructure. Ground stations connect satellites to terrestrial networks and collect satellite information ranging from tracking and telemetry to imagery and scientific data. The stations also upload information to spacecraft,...
Year: 2010
One specialized type of system that uses both satellites and ground stations is dedicated to space situational awareness (SSA). An SSA system tracks satellites and other objects orbiting Earth. This is accomplished through a series of ground stations which are dedicated to scanning the sky via a...
Year: 2010
An essential element of space infrastructure, ground stations transmit commands to and receive data from spacecraft. They also often contain facilities to process that data, particularly in the case of Earth observation satellites. The data sent from ground stations includes command and control...
Year: 2011
A series of SSN upgrades are underway. In 2011, a DARPA-funded space surveillance telescope underwent testing. After nine years of development, the new telescope, located at White Sands Missile Range, New Mexico, is capable of capturing wide-field views of objects in GEO orbit. While the SSN uses...
Year: 2008
The activities of spacefaring nations increased in 2008, and the policies of those and other countries continue to evolve. These policy changes often reflect the need to fund or authorize activities in response to steps taken by other national space programs, particularly when matters of national...
Year: 2011
As space activities across the globe become more dynamic—blending commercial, government, and cross-border activities—governments increasingly see a need for a formal space policy to provide a framework for coordination and integration of activities. Effective space policy can foster public...
Year: 2010
The satellite services sector, which includes fixed and mobile satellite services, registered $## billion in 2010 revenue, up from $## billion in 2009. Both types of services communicate information in video, voice, and data formats. Fixed satellite services (FSS) refer to the delivery of satellite...
Year: 2011
Space activities in South Africa are funded through the Department of Science and Technology (DST). In FY 2011, which ran from April 2011 to March 2012, the DST planned to spend ## million rand (US$## million) on space activities executed through two programs: the South African National Space...

While mechanisms such as the PISA test reveal a cross-national focus on primary and secondary STEM competency, a more direct measure of the potential international space workforce is offered through a comparative analysis of STEM university graduates by country.
Year: 2013
The number of STEM first-degree (bachelor’s equivalent) graduates in many space-relevant countries has increased in recent years. The disciplines included here are physical, biological, and computer science; engineering; and mathematics.
Topic: TIMSS
Year: 2013
The TIMSS study also assesses mathematics and science knowledge and skills. Unlike PISA, which focuses on broader mathematical and scientific literacy of students nearing the end of compulsory education, TIMSS is designed to align broadly with the mathematics and science curricula in participating...
Topic: PISA
Year: 2013
Trends in international primary and secondary STEM education can be compared across countries using two widely respected international exams. The Programme for International Student Assessment (PISA), carried out by the Organisation for Economic Co-operation and Development (OECD) every three...
