From beaches and salt marshes, to the open ocean, sea ice, and the sea floor, Earth’s oceans are dynamic. This challenge category will ask you to use NASA data to better understand and protect Earth’s oceans.

Across human history, our moon has been a faithful beacon to observers of the Earth’s sky. Challenges in this category will ask you to think creatively about our nearest neighbor, and to interpret NASA data and concepts to find solutions.

From our neighboring planets to those only visible through the most powerful telescopes, other planetary bodies have long fascinated scientists, artists, and explorers. This challenge category will ask you to use NASA data to explore the systems of other planets, near and far.

Whether your interests lie in our solar system or beyond, outer space provides seemingly endless opportunity for study, exploration, and inspiration. Challenges in this category will invite you to think hard and be creative about space science and exploration, whether your viewpoint is scientific, technologic, artistic – or all three!

The Earth is composed of complicated systems – land, water, air, living things, and the planet itself. Understanding how these systems work together is important. Challenges in this category will ask you to craft solutions using NASA data – a story, a game, a video, any product of your design – that capture what it’s like to live on Earth.

Pose your own challenge, and create a solution of your own choosing! Reminder: Solutions in this category are wonderful, but they are not eligible for global judging or awards from NASA.
