Rats in a transparent morris water maze use elemental and configural geometry of landmarks as well as distance to the pool wall

The aim of this study is to evaluate whatare the dimensions of a panorama of discretelandmarks that a rodent will store in order toreturn to a previously visited target. Ratswere trained to locate a hidden platform in acircular pool of clouded water set within aquasi-spherical enclosure. In order to find theplatform, they had to learn the geometricrelations between the platform and asurrounding set of three discrete landmarks,highly visible through the transparent wall ofthe pool. In test trials without a platform,the array of landmarks was so manipulated as todissociate the effect of actual distance to thelandmarks, of their angular separation, and oftheir apparent dimension. Animals were shown torely equally on angular separation and apparentdimension. The role of actual distance couldnot be definitely ascertained, as animals wereshown to additionally rely on the distance tothe pool wall in order to locate theplatform.

Space traffic control: a view of the future

This paper provides an overview of a system for providing reliable, ongoing, timely situational awareness services to satellite operators. Such services would include close approach warnings, warnings of potential radio frequency interference, and other offerings designed to help make operators aware of possible threats to the safe operation of their spacecraft and measures they can take to lessen these threats. The paper discusses current trends, proposes operational requirements, and speculates on the type of organization that may emerge to provide space traffic control services. It highlights how the detailed information required for such services may affect the evolution of the use of space.
