📸🌏Two views of Earth—more than 50 years apart.

Apollo gave us the Blue Marble. Artemis II offers a fresh perspective. And in between, the Landsat Program has steadily kept watch.

Since 1972, Landsat’s repeat coverage has built the world’s longest continuous record of Earth’s land surface, with millions of images available to everyone.

Today, Landsat 8 and Landsat 9 revisit most places on Earth every 8 days, turning snapshots into science and action.

This long-term record supports efforts to improve agriculture, manage water resources, monitor land-use change, respond to natural disasters, and deepen our understanding of our dynamic planet.

The Landsat program is a long-standing partnership between @USGS and @NASA.

Earthrise (Artemis II’s version)

The Artemis II crew took this photo of Earthrise—when Earth appears to rise from behind the lunar horizon—as the crew flew around the far side of the Moon on April 6, 2026. In this view, Earth looks like a crescent and the Moon is on the right. https://t.co/QiMMpLXeAy

🌊 Coastal cities may experience larger, more intense floods in the future.

✍️ New research looked into the future of flooding in Shanghai and showed that by 2100 the floods of Shanghai could increase in extent by 80% - and be much deeper.

Do you see that dark smudge-like shape moving across the top of this morning's Pacific view from @NOAA's #GOESWest (#GOES18) 🛰️?

You're seeing a satellite eclipse! Twice a year, around the equinoxes, the GOES satellites pass through Earth’s shadow and can pick up stray sunlight—creating brief streaks or glitches like this. Don't worry, it's normal.
