Expedition 73 Flight Engineers Jonny Kim and Zena Cardman, both NASA astronauts, practice Canadarm2 robotic maneuvers at the robotics workstation inside the International Space Station’s cupola. The duo was preparing for the robotic capture of the Northrop Grumman Cygnus XL cargo spacecraft that launched on Sept. 14, 2025, and arrivedContinue Reading
California air regulators adopted new rules designed to reduce methane leaks and better respond to disastrous underground fires at landfills statewide.Continue Reading
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
As climate talks in Belém enter their final stretch, negotiators are working on three fronts: technical details, ministerial consultations, and Presidency-led discussions. Behind the jargon and complex frameworks lie fundamental choices for more than 190 countries – choices that could shape how the Paris Agreement, signed in 2015, is turnedContinue Reading
With the clock ticking on climate negotiations in Belém, UN Secretary-General António Guterres and Brazil’s President Luiz Inácio Lula da Silva, speaking separately, delivered a united message: the world is watching, and compromise cannot wait.Continue Reading

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
