For more than 20 years, astronauts have been shooting photographs of Earth from the International Space Station (ISS). Here’s a chance for you to vote for your favorite. This year, the NASA Earth Observatory’s annual Tournament Earth contest features photos of our planet taken by astronauts aboard the ISS. Over the next five weeks, you can vote in each round, until the final winner is decided in April. Voting in round 1 started on Monday (March 8) and will end on March 15 at noon U.S. Eastern Time. Go here to participate.

The contest photos are divided into four groups: Unity, Cupola, Destiny, and Tranquility, named after four key modules/parts of the ISS. The Unity and Cupola groups include images chosen by ISS astronauts and the Earth Science and Remote Sensing team that trains and supports them. The photos in the Destiny and Tranquility groups were chosen by readers like you.
