Fill Out Your Bracket for Tournament Earth 2021 (Astronaut Photography Edition)

March 9th, 2021 by NASA Earth Observatory

It is that time of year again…Tournament Earth is back! This time, the theme is astronaut photography. For more than 20 years, astronauts have been shooting stunning photos of Earth from the International Space Station that highlight the planet’s beauty, complexity, and vulnerabilities.

So which are the most unforgettable photographs of Earth taken from the space station? Over the next five weeks (March 8-April 13), you can help decide.

The first round has already begun. Cast your vote here:

While you wait for the Round 1 results, download the bracket here and challenge your friends. After you fill out that bracket, post your predictions in the comment thread for which four photos will make the semifinals and which one will be crowned champion. We can’t offer prize money or a trip to the Moon, but bragging rights are forever if you can guess the eventual champion.

Also, bookmark this space. We will provide updates later in the tournament and highlight some of your predictions, commentary, and insights lower in the post. Just remember to use the hashtag #TournamentEarth and tag @NASAEarth on social media (we’re on Twitter, Facebook and Instagram) or we might not see your post.

If you are curious about the team behind the photos you see in Tournament Earth, check out our Picturing Earth video series.

Happy voting!
