massive-hidden-structures-deep-inside-earth-may-explain-how-life-began

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle prevented the planet from developing strong chemical layers afterContinue Reading

landsat-calibration-&-validation

Calibration & Validation Closely calibrated and validated data are a hallmark of the Landsat Program. For medium-resolution satellite data, Landsat is considered the “gold standard” because of the program’s tradition of rigorous, independently verified calibration that is diligently reported and documented in peer-reviewed literature. This level of calibration takes considerable effortContinue Reading
