Mitigation Policy Scenario of Space Debris Threat Related with National Security

Space Debris Mitigation Utilizing Laser Ablation

Space debris poses an increasingly serious threat to satellites and spacecraft. Our project will aim to mitigate this problem using an array of kilowatt-class lasers, powered by photovoltaics. An experiment was implemented to study this using a directed energy system to completely vaporize or propel space debris out of Earth’s orbit. Common materials found in space debris were tested using a 60...

A Scenario and Technologies for Space Debris Removal

Since the number of satellites in Earth orbit is steadily increasing, space debris will eventually pose a serious problem to near-Earth space activities if left unchecked, and so effective measures to mitigate it are becoming urgent. Equipping new satellites with an end-of-life de-orbit or orbital lifetime reduction capability could be an effective means of reducing the amount of debris by redu...

Security Threat Mitigation Trends in Low-Cost RFID Systems

The design and implementation of security threat mitigation mechanisms in RFID systems, specially in low-cost RFID tags, are gaining great attention in both industry and academia. One main focus of research interests is the authentication and privacy techniques to prevent attacks targeting the insecure wireless channel of these systems. Cryptography is a key tool to address these threats. Never...

The biological threat to U.S. water supplies: Toward a national water security policy.

In addition to providing potable drinking water, U.S. water systems are critical to the maintenance of many vital public services, such as fire suppression and power generation. Disruption of these systems would produce severe public health and safety risks, as well as considerable economic losses. Thus, water systems have been designated as critical to national security by the U.S. government....
