Each section is unique, and only one scientist can analyze a given sample at one time. However, sections of precious extraterrestrial samples are rare and often difficult to acquire. For a meteorite prepared as a thin or thick section, backscattered electron (BSE) and X-ray elemental maps acquired at the effective resolution limit for these two modalities (РІв‚¬С50Р’В nm/pixel and РІв‚¬С2Р’В РћСm/pixel, respectively) in a scanning electron microscope (SEM) are critical for determining if a given sample can answer a given scientific question. The РІР‚Сљfirst lookРІР‚Сњ data that is often critical for cosmochemists is a detailed mineralogic and petrographic description of the meteorite sample. For example, the presolar grain database (Stephan etР’В al., 2020) has been used extensively by cosmochemists and astronomers to explore a variety of problems (e.g., Pignatari etР’В al., 2015).

However, there are a few open data sets that have proven very useful to the community.

The different types of laboratory instrumentation (electron beam instruments, ion probe, synchrotron, etc.), techniques, protocols, standardization/calibration, and samples make it difficult to usefully share data in a standard way with other researchers. Open data sets in cosmochemistry, meteoritics, and astromaterials are more scarce. Open data setsР’В also facilitate a РІР‚Сљfirst lookРІР‚Сњ into an interesting scientific question, with more in-depth studies that follow. These open data setsР’В allow for greater transparency of published work and exploration of data in novel ways by people outside of the main community. Many astronomy and planetary science data sets are available for any interested scientist to analyze. In recent years there have been increased efforts to make raw scientific data publicly available online.
