Terra’s twenty years of data continue to contribute to how we understand Earth and how we respond when disasters strike. Terra’s five sensors help us understand out changing planet and provide critical data used in applications from food security, volcanic monitoring, wildfire safety, public health, and climate modeling.

With no maneuvers planned to sustain Terra’s altitude and crossing time, Terra will slowly get closer and closer to Earth – crossing the equator earlier and earlier as time passes. What’s Next?Īfter more than 20 years orbiting at 705 km above Earth’s surface and routinely crossing the equator at approximately the same time every day, Terra is now drifting.
