Raman spectroscopy is a non-destructive technique that is used in cosmochemistry for identification of minerals and to evaluate the bonding and composition of organic molecules. The technique does not require special sample preparation raw rock samples, polished sections, fine-grained powders, and liquids can be analyzed. Raman spectroscopy is the basis for several instruments that are under consideration for upcoming NASA missions. 

What Earth-based research must be done to explore those limits so that NASA missions would be able to recognize, conserve, and study alien life that is encountered ... 

Pursue the origin of life, especially on the basis of information from NASA missions, the inventory of organic materials in the cosmos, and interactions between organic materials and minerals set in a planetary context. 

If the second is the case, we would be called on to creatively define chemistries that might support life in nonaqueous solvents. They might be used to support NASA missions to locales, such as Titan and Venus, where liquids other than water are abundant. 

In DNA, the polyanionic backbone dominates the physical properties of DNA. Replacing one nucleobase with another, therefore, has only a second-order effect on the physical behavior of the molecule. That allows nucleobases to be replaced during Darwinian evolution without losing properties essential for replication. Therefore, a repeating charge may be a universal structural feature of any genetic molecule that supports Darwinian evolution in water. Polycationic backbones may be as satisfactory as polyanionic backbones, however. Thus, if NASA missions detect life in water on other planets, its genetic system is likely to be based on polyanionic or polycationic backbones even if its nucleobases differ from those found on Earth. That structural feature can be easily detected with simple analytical devices. 

It is conceivable that if we understood the processes by which life arises, we might constrain the existence of life to a small number of locales, to a similar array of organic species, or to a smaller number of liquid phases than the more general thermodynamic-structure-solvent trichotomy, discussed above, would tolerate. That would, in turn, be considered alongside emerging models of planetary formation to provide better direction for the targets of National Aeronautics and Space Administration (NASA) missions to the solar system.

Nearly all robotic explorers orbiting the sun or on far off trajectories to other planets use a variety of spectrometers. Individual NASA missions each have readily accessible education pages associated with them and advanced technical descriptions of instruments are generally available for download. Future potential resources can be found by beginning at www.nasa.gov and selecting the Education hyperlink. Some current resources to consider include ...

Over the course of the 18 month program, the NRPCT evaluated all reasonable reactor and energy conversion technologies and selected a reference coolant and energy conversion approach that offered the best prospect of meeting NASA mission requirements within the schedule and cost constraints. The NRPCT also recommended the use of uranium oxide fuel. NRPCT was working to select reference core and plant structural materials, a...
