Earth: September 2021

Shane Kimbrough @astro_kimbrough Can you find Grand Prismatic Spring in this pic? The 300-foot wide hot spring has its famous rainbow-colored edges.

Thomas Pesquet: Impressive fires in Canada. We were chatting this week and we realised that we have missed a whole summer on Earth now.

For decades, scientists have assumed that losses in Arctic sea ice cover allow for the formation of more clouds near the ocean's surface.

Sea ice in the Arctic appears to have hit its annual minimum extent on Sept. 16, after waning in the 2021 Northern Hemisphere spring and summer. The summertime extent is the 12th-lowest in the satellite record, according to scientists at the NASA-supported National Snow and Ice Data Center and NASA.

Thomas Pesquet: Andes again. This area, between Peru, Chile, Bolivia, is an infinite source of magical shapes and striking colours. Do you prefer a burgundy red lake, or a neon blue amphitheatre?

Thomas Pesquet: Framing is everything, the Syr Darya river at two zoom levels: the winding rivers remind me of wisps of smoke. At the borders of the river you can see the #CropArt where humans have naturally started growing food using the life-giving water a river brings.

The Copernicus Sentinel-2 mission takes us over the Danube Delta - the second largest river delta in Europe.

For centuries, explorers have tested the icy waters of the Arctic, looking for sea routes through the cluster of islands north of mainland Canada.

Thomas Pesquet: The Galápagos Islands are famous for their wildlife and Charles Darwin who studied the area, as well being a poster for bio-diversity 🐢.

Thomas Pesquet: A sight we see often while flying over our planet: peas in the desert, a Pacman invasion, or Earth's record collection?

Millions of people suffer from food insecurity around the globe. With the help of Earth-observing satellites, the NASA-USAID SERVIR project is hoping to reduce that number.

The Earth is heating up. The effects of human-caused global climate change are becoming more and more apparent as we see more record-breaking heat waves, intense droughts, shifts in rainfall patterns and a rise in average temperatures. And these environmental changes touch every part of crop production.
