NASA Returns to Arctic Studying Summer Sea Ice Melt
What happens in the Arctic doesn’t stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth’s rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost part of…
NASA’s ICON Mission Ends with Several Ionospheric Breakthroughs
After contributing to many important findings on the boundary between Earth’s atmosphere and space — an area where space weather can interfere with both satellites and communications signals — NASA’s ICON (Ionospheric Connection Explorer) mission has come to an end.…
Watch Carbon Dioxide Move Through Earth’s Atmosphere
What we’re looking at This global map shows concentrations of carbon dioxide as the gas moved through Earth’s atmosphere from January through March 2020, driven by wind patterns and atmospheric circulation. Because of the model’s high resolution, you can zoom…
NASA-Funded Studies Explain How Climate Is Changing Earth’s Rotation
Researchers used more than 120 years of data to decipher how melting ice, dwindling groundwater, and rising seas are nudging the planet’s spin axis and lengthening days. Days on Earth are growing slightly longer, and that change is accelerating. The…
The Earth Observer Editor’s Corner: Summer 2024
NASA’s third EOS mission—AURA—marked 20 years in orbit on July 15, with two of its four instruments—MLS and OMI—still collecting quality datasets.
The Earth Observer’s 35th Anniversary
Welcome to a new era for The Earth Observer newsletter! Our 35th anniversary also marks the official public release of our new website. Over the past year and a half, The Earth Observer has migrated from a print publication (the last printed issue was November–December 2022)…
Summary of the 2023 Sun – Climate Symposium
Introduction Observations of the Sun and Earth from space continue to revolutionize our view and understanding of how solar variability and other natural and anthropogenic forcings impact Earth’s atmosphere and climate. For more than four decades (spanning four 11-year solar…
Science Activation’s PLACES Team Facilitates Second Professional Learning Institute
The NASA Science Activation Program’s Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES) team successfully led their second Professional Learning (PL) Summer Institute (SI) at Northern Arizona University (NAU) in Flagstaff, Arizona from June 11-13, 2024. The team led…
NASA Science Activation Teams Present at National Rural STEM Summit
NASA Science Activation (SciAct) teams participated in the National Rural STEM (Science, Technology, Engineering, & Mathematics) Summit held June 4-7, 2024 in Tucson, Arizona. Hosted by Kalman Mannis of the Rural Activation and Innovation Network (Arizona Science Center) and the…
NASA’s ECOSTRESS Maps Burn Risk Across Phoenix Streets
Roads and sidewalks in some areas get so hot that skin contact could result in second-degree burns. Researchers at NASA’s Jet Propulsion Laboratory in Southern California have mapped scorching pavement in Phoenix where contact with skin — from a fall,…
