A Safe Way to Implement a Database of Satellite Anomalies

Jun 2, 2014

Satellite anomalies are malfunctions caused by solar particles, cosmic rays, or even space debris. A shared database could help identify solutions to prolong the lifetime of spacecraft that experience problems, and could be implemented in a way that would protect the privacy of the satellite operators.

Satellites for Rent

Nov 7, 2013

Reports earlier this year that the U.S. Department of Defense leased a Chinese satellite to support military operations in Africa sparked concern that the arrangement could compromise control over U.S. military communications, or, worse, allow Chinese intelligence gatherers access to privileged military data.

Space Safety Coordination: A Norm for All Nations

As space becomes more congested with satellites, the need for every nation to actively participate in the space safety coordination system grows. Most spacefaring countries participate, but a few countries do not—notably, Russia and China. That creates greater potential for collisions and hazards from debris.

Our Reliance on Space Tech Means We Should Prepare for the Worst

Space-enabled connectivity, technology, and services support a diverse array of political, military, and economic activities, many of which modern life on Earth relies upon and which the public often takes for granted. How prepared is global society to deal with the growing reliance on this technology and to mitigate associated risks?
