Earthset

The Artemis II crew captured this view of Earth setting on April 6, 2026, as they flew around the Moon. As the astronauts flew over the Moon’s far side, the crew photographed and described terrain features including impact craters, ancient lava flows, and surface cracks and ridges formed as the Moon slowly evolved over time.

Thinking of You, Earth

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 […]

Hello, World

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 […]

Arctic Winter Sea Ice Ties Record Low, NASA, NSIDC Scientists Find

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 […]

NASA-ISRO Satellite Captures Pacific Northwest Through Clouds

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 […]

See NASA’s GUARDIAN Catch a Tsunami

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 […]
