Vande Hei posted this majestic image to social media on Dec. 17 saying, "Hello Little Rock, Memphis, Jackson, New Orleans, Birmingham, Miami, and many places in between! #SpaceIsCloserThanYouThink" Currently, there are six people living and working on the space station. They are not only conducting cutting-edge research aboard the orbital laboratory; their images of Earth help monitor conditions on our planet, and also showcase its beauty.

Rhea is a heavily-cratered, airless world, while Titan’s nitrogen-rich atmosphere is even thicker than Earth’s. This natural color image was taken in visible light by the Cassini spacecraft on Nov. 19, 2009, at a distance of approximately 713,300 miles (1,148,000 kilometers) from Rhea. After a nearly 20-year mission that overflowed with discoveries, the Cassini spacecraft ended its mission on Sept. 15, 2017. Credit: NASA/JPL-Caltech/Space Science Institute
What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
