NASA | Space Geodesy Profile: Chopo Ma

The video discusses NASA's involvement in space geodesy, focusing on the development of precise terrestrial reference frames. Initially, the field explored questions about continental movement, such as the North American and European plates. Today, the emphasis is on creating accurate metrics to understand Earth's spatial relationships over time. This precision is crucial for measuring phenomena like sea level rise and ensuring the reliability of scientific interpretations.
