It is a harsh environment where safe operations are threatened by natural occurrences such as space weather.

This environment is also fragile, threatened by the accumulation of debris that results from all human activities, but which is exacerbated by accidental collisions and the intentional destruction
of objects in orbit. Even the smallest pieces of debris can be harmful to satellites operating in space.

Stress to the sustainability and carrying capacity of the space environment is growing alongside increasing congestion, as access to and use of space expands rapidly. The emergence of new services, such as space-based Internet, that use massive constellations of satellites in low Earth orbit to provide constant, global service coverage are also contributing to congestion and growing demand for space’s natural resources.

Environmental challenges are exacerbated by limits to our knowledge about the space environment. Although capabilities are expanding, at this moment, we don’t have sufficiently precise information on what exactly is in outer space, where it is, and how it is moving through orbit to ensure that the objects and people that we send there remain safe. The same can be said of our ability to predict and collectively respond to natural threats such as space weather. Improving the quality, timeliness, and distribution of information about the space environment is a significant focus of space security.

Space Situational Awareness

ABOUT Space Situational Awareness refers broadly to knowledge about the natural and human-made elements of the space environment, which the European Space Agency specifies as “the provision of timely and accurate information regarding the space environment, and particularly hazards to infrastructure in orbit and on the ground.” These hazards could…

Natural Hazards in Space Weather

WHAT IS SPACE WEATHER? Space weather refers to a collection of physical processes, beginning at the Sun and ultimately affecting infrastructures on Earth and in space that support human activities. The Sun emits coronal mass ejections and plasma streams that release electromagnetic radiation and electrically charged particles. This expulsion of…

Managing Space-Based Resources

ABOUT The ability to operate a satellite in outer space requires access to radiofrequencies and orbital positions, both scarce resources. As the number of spacefaring states, commercial operators, and satellite applications grows, demand for these resources increases. Efficient and equitable managing of these resources to ensure long-term availability requires international…
