This paper is a controversial look at some of the beliefs (myths) held by the space community which block us from formulating a successful Mars Exploration strategy. The origins and consequences of these myths are presented in contrast with attitudes and actions which would have a better chance of getting us to Mars than we currently have.
Since the 1960's there have been efforts world-wide to develop robotic mobile vehicles for traversing planetary surfaces.
The Mars Exploration Program is pioneering a series of better, faster, cheaper missions to Mars over at least the next 10 years, and possibly well into the 21st century.
In the wake of the failure of the Mars Observer mission in 1993, a long-term program of robotic exploration of Mars was established. The themes of the Mars Exploration Program are to understand life, climate, and resources on Mars, with these themes tied together by the common thread of water. The Mars Exploration Program comprises at least one Discovery mission (Mars Pathfinder), the Mars Surveyor Program, plus sample return missions and other missions to prepare possible human expiditions to Mars.
The Mars Pathfinder Microrover Flight Experiment (MFEX) will be carried by the Mars Pathfinder mission to the surface of Mars, where it will perform technology, science and Mars mission engineeering experiments in July, 1997.
Many urban hospitals are becoming overloaded with drug abuse cases requiring chemical analysis for identification of drugs. In this paper, the requirements for chemical analysis of body fluids for drugs are determined and a system model for automated drug analysis is selected. The system as modeled, would perform chemical preparation of samples, gas-liquid chromatographic separation of drugs in the chemically prepared samples, infrared spectrophotometric analysis of the drugs, and would utilize automatic data processing and control for drug identification. Requirements of cost, maintainability, reliability, flexibility, and operability are considered.
