One of the most important goals of planetary missions is the dissemination of data to the scientific community. To this end, standardized digital archives are needed to allow access to diverse datasets. In addition, software is needed to process data from the raw level to the map projected level. These software systems are called Geographic Information Systems, and are a popular choice among planetary scientists. These systems allow scientists to store, analyze, and retrieve Earth-based environmental geodata in the most efficient way possible.
The NASA Hubs address a wide range of issues pertaining to the environment. By integrating the outputs, the Hubs provide governments, emergency response agencies, and decision makers with a comprehensive picture of the environment and how it is changing. As a result, NASA Hubs are an important component of Earth-based environmental science.
Earth-Based Environmental Science uses a variety of disciplines to understand the Earth. The major disciplines include physics, chemistry, biology, and chronology. Throughout this process, scientists build a quantitative and qualitative understanding of the Earth. In addition, Earth-based Environmental Science is used to develop environmental ethics.
The Earth’s atmosphere plays a pivotal role in maintaining the planetary ecosystem. It is a thin layer of gases that is held in place by the planet’s gravity. This layer contains 78% nitrogen, 21% oxygen, and 1% argon and other inert gases. The air also contains trace amounts of many chemical compounds and water vapor.
