Reykjavik, Iceland | ESA
The European Space Agency's Copernicus Sentinel-2A satellite takes us over the capital of Iceland, Reykjavik. As a volcanic island famous for its volcanoes, glaciers, lakes, lava and hot springs, Iceland attracts tourists all year round with its vast array of natural wonders.

This true color image shows us the small city of Reykjavik, home to around 120, 000 people, and seen in the lower central part of the image. The port town of Akranes, 20 km north of the capital, is also shown in grey in the center of the image. In between the two lies Mount Esja, standing just over 900 meters tall, and providing a dramatic backdrop to the capital.

In the upper left part of the image, ‘kettle holes’ are visible as small dark green dots scattered across the reddish brown area. Kettle holes are formed when blocks of ice break away from glaciers and then become buried in outwash. When these buried blocks of glacier ice melt away they leave behind holes, which become filled with water and turn into kettle hole lakes. They are often found in areas that were covered in ice during the last ice age, which ended around 12,000 years ago. Kettle holes are common in Michigan in the United States, as well as in parts of Germany, Austria and the UK.

The Sentinel-2 mission is tasked with monitoring our changing lands. Designed specifically to monitor vegetation, it can also detect differences in sparsely vegetated areas, as well as the mineral composition of soil, as found in Iceland.

This image, which was captured on November 1, 2017, is also featured on the "Earth from Space" video program.

NASA Insight: German Scientist to Take Mars' Temperature
Insight Lands on Mars in November 2018 | NASA 360
August 2, 2018: The German Aerospace Center (DLR) developed and built an instrument to fly on NASA's InSight mission that will measure the heat coming out of the interior of Mars. The instrument's principal investigator, Tilman Spohn, is looking forward to studying the internal heat of the mysterious Red Planet.

Landing in November 2018, NASA's InSight will probe beneath the surface of Mars, study the planet's interior and shed light on how rocky planets—inside and outside our solar system—form.

InSight is part of NASA's Discovery Program of competitively selected solar system exploration missions with highly focused scientific goals. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Discovery Program for the agency's Science Mission Directorate in Washington. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages InSight for the NASA Science Mission Directorate.
