The state was unusually dry for much of 2025, but the intensity of the drought has ratcheted up since January 2026.
On April 4, 2026, NASA astronaut and Artemis II Commander Reid Wiseman peers out of one of the Orion spacecraft’s main cabin windows, looking back at Earth, as the crew travels towards the Moon. The Artemis II astronauts – Wiseman and fellow NASA astronauts Christina Koch and Victor Glover, and CSA (Canadian Space Agency) astronaut […]
NASA astronaut and Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft’s window after completing the translunar injection burn. There are two auroras (top right and bottom left) and zodiacal light (bottom right) is visible as the Earth eclipses the Sun. This and another photo of Earth are the first […]
In two recent studies, researchers used Landsat data to fill key gaps in our knowledge of reservoir structure and dynamics.
For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million square kilometers), very close to the 2025 peak of 5.53 million square miles (14.31 million […]
Seattle and Portland, Oregon, are among the cloudiest cities in the United States. But that infamous cloud cover is no match for the U.S.-Indian Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar), which is designed to peer straight through clouds. Doing so allows scientists to study the Pacific Northwest’s natural landmarks and bustling port cities like […]
A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move.. The animation breaks down a real-life […]
Explore how rivers move, change, and sustain life across the planet with SWOT data.
Plains around the San Andreas Fault and across Carrizo Plain National Monument are awash with yellow as wildflowers bloom.
A NASA laser reflecting technology that will aid Global Positioning System (GPS) accuracy is now operational as of March 9. The instrument, known as a laser retroreflector array, or LRA, launched aboard GPS III SV-09, the ninth of U.S. Space Force’s Block III Global Positioning System satellites, on Jan. 27. LRAs are sets of mirrors […]
