The European Space Agency has initiated, in the context of its General Studies Programme, a study of the possible use of space for studies in pure and applied plasma physics, in areas not traditionally covered by “space plasma physics”. A team of experts has been set-up to review a broad range of area including industrial plasma physics and pure plasma physics, astrophysical and solar-terrestrial areas. A set of experiments have been identified that can potentially provide access to new phenomena and to allow advances in several fields of plasma science. These experiments concern phenomena on spatial scale (102 to104 m) intermediate between what is achievable on ground experiment and usual solar system plasma observations.

The purpose and principles of spaceborne lidar are described, giving particular attention to candidates for space deployment, including simple backscatter lidar for measuring of cloud top height, cloud extend and optical properties, differential absorption lidar providing high vertical resolution measurements of humidity, temperature and pressure, a wind profiling lidar with the unique capability of improved weather forecasting and global dynamics, and a ranging and altimeter lidar for very accurate measurement of surface features, including ground, sea and ice cap height for solid earth studies.

The giant panda, Ailuropoda melanoleuca is an endangered species that is protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Endangered Species Act (ESA). Numerous factors have led to a decline in giant panda populations in China including habitat loss from human activity, poaching, panda inbreeding and a low reproductive rate. This capstone analyzes the effects of CITES and ESA as policies for the protection of panda populations and their habitat. CITES and ESA provide some protection for panda populations in the United States. However, these policies do not address panda habitat protection in China.
