Seasonal changes redistribute enough water around Earth to shift the planet’s center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations because Earth’s center of mass is a crucial reference point for satellite navigation and elevation measurements.
For over 50 years, the Landsat program has provided the longest continuous satellite record of Earth's land surface from space. Landsat 9, launched in 2021, is the latest mission in this remarkable legacy.
New infrared surveys of silicates and related minerals provide insights for geological research, renewable energy, and rare Earth mineral exploration.
