Participate in the 50th anniversary of Earth Day by asking our experts anything about NASA’s role in Earth Science! 

This year marks the 50th anniversary of Earth Day, and to commemorate the big day we’re bringing you exclusive access our Acting Director of Earth Sciences, Sandra Cauffman, and Associate Administrator for the Science Mission Directorate, Dr. Thomas Zurbuchen! They will be teaming up to take your questions in an Answer Time session on Earth Day, April 22, from 12-1pm EDT here on NASA’s Tumblr! Make sure to ask your question now by visiting http://nasa.tumblr.com/ask!

Our investment in space – both the unique Earth science we conduct from orbit and the technology we’ve developed by living in space and exploring our solar system and universe – is returning benefits every day to people around the world, particularly those who are working on environmental issues. From documenting Earth’s changing climate to creating green technologies to save energy and natural resources, we’re working to help us all live more sustainably on our home planet and adapt to natural and human-caused changes. 

NASA Earth Science Fun Facts!

From space we study: dust storms, volcanoes, flooding, coral reefs, night lights, wildfires, urban growth, food production, mosquito tracking and other human health issues, precipitation across the world, hurricanes and typhoons, soil moisture, land and sea ice, and changes to the land and sea surfaces.

From airborne research planes we track: changes in polar ice, glaciers, sea level rise, cloud formation, storms, sea level rise and Earth’s changing landscape. 

Our Earth science focus areas include: Atmospheric Composition, Weather and Atmospheric Dynamics, Climate Variability and Change, Water and Energy Cycle, Carbon Cycle and Ecosystems, Earth Surface and Interior
