This article is a reflection on the past 36 years of NASA's Earth Observing System (EOS) and its various missions, highlighting some of the most significant achievements and milestones in the field of Earth science. The article is published by "The Earth Observer," a newsletter that has been chronicling NASA's EOS efforts since 1989.
The article covers a range of topics, including:
1. Soil Moisture Active Passive (SMAP) mission: Launched in 2015, SMAP measures soil moisture and freeze-thaw state, providing critical data on the water cycle and its impact on climate.
2. Global Ecosystem Dynamics Investigation (GEDI) mission: Launched in 2018, GEDI uses laser pulses to measure forest canopy height and vertical structure, advancing our understanding of carbon and water cycling processes.
3. ECOSTRESS mission: Launched in 2018, ECOSTRESS monitors evapotranspiration, the combined process of plant water loss through transpiration and evaporation from the soil surface.
4. NASA-ISRO Synthetic Aperture Radar (NISAR) mission: Launched in 2025, NISAR offers high-resolution observations of Earth's land and ice with unmatched precision, providing real-time insights into earthquakes, floods, and climate shifts.
The article also reflects on the evolution of "The Earth Observer" newsletter over the past three-and-a-half decades, highlighting its commitment to delivering high-quality content to the NASA Earth Science community.
Key points from the article include:
* The EOS has revolutionized society's knowledge of our home planet and how humans are altering it.
* Continuous global observations have improved our understanding of the Earth's systems and processes.
* NASA's Earth science missions have made significant contributions to climate change research, ecosystem management, and disaster response.
* "The Earth Observer" newsletter has chronicled the progress of these missions over the years, providing a valuable resource for the NASA Earth Science community.
Overall, this article is a tribute to the achievements of NASA's EOS and its various missions, highlighting their importance in advancing our understanding of the Earth's systems and processes.
