Exploring the Use of Space Resources

As the space infrastructure continues to grow, it is possible to expand the sphere of economically useful resources into space and neighboring planetary bodies. NASA, ESA, and the Japanese Aerospace Exploration Agency (JAXA) are among the space agencies that have conducted studies or workshops to address the feasibility of using extra-terrestrial resources, or In Situ Resource Utilization (ISRU).

Concerned about Space Debris

Of growing concern to the international community is orbital debris— ranging from paint flecks to entire upper stages— resulting from half a century of space access. It is estimated that 100,000 to 150,000 objects larger than one centimeter remain in orbit.

Hoping to Nip Disease in the Bud and Keep Electricity Flowing

65 countries, the European Commission (EC) and more than 40 international organizations are supporting the development of a Global Earth Observation System of Systems (GEOSS) during the next decade. GEOSS is proposed as an overarching system of existing and future earth observations systems.

Hurricanes and Disaster Monitoring Constellations

The dominant space technology that supports energy and Earth resources is remote sensing. Remote sensing images are not limited to the wavelengths of light that can be seen by the human eye. Earth sensing satellites record primarily microwave, infrared, and visible light wavelengths.

Using Satellite Terminals in Hotels

Hotels in remote tourist locations use very small aperture terminals (VSATs) to keep track of bookings and current capacity. In 1999, Best Western had 560 sites connected by a VSAT network, while, more recently, Six Continents Hotels, Inc., contracted Gilat to provide a satellite network to more than 2,500 locations in the United States and Canada.
