An orbital sunrise reveals cloud tops above the Pacific Ocean northeast of New Zealand as the International Space Station orbited 260 miles above on Feb. 10, 2023. Astronauts aboard the space station see 16 sunrises and sunsets per day due to their high orbital velocity—17,500 miles per hour. In the more than 20 years that people have been living aboard, the station has circumnavigated Earth tens of thousands of times.

While the International Space Station orbited over the Gulf of Mexico on Sept. 19, 2022, NASA astronaut Bob Hines captured this image of South Padre Island, a barrier island along the coast of Texas. The island is part of the greater Padre Island, the longest barrier island in the world, which spans a length of 113 miles (182 kilometers). Barrier islands along the Gulf and East coasts of North America play a critical role protecting the mainland from the damaging effects of storms. They bear the brunt of large storm surges and reduce flooding on the mainland.
