Using lasers to draw maps

LiDAR (Light Detection and Ranging) is a technology that uses laser light to measure distances and create detailed maps of surfaces. By calculating how long it takes for light to bounce back, scientists can determine the height and shape of objects, helping them map landscapes on Earth and even explore other planets.

Understanding satellite resolution

Satellite images are built from thousands (or millions!) of tiny squares called pixels, and each one adds a small piece of information to the overall picture. The more pixels an image has, the higher its resolution — allowing scientists to see finer details and better understand Earth’s surface.

Measuring air quality

Ozone Where We Live (OWWL) is a NASA project that helps scientists understand air quality in California’s San Joaquin Valley. Volunteers collect ozone and other air pollution data using simple sensors, which NASA researchers use to improve satellite measurements and air quality predictions.

Classify coral reefs

NeMO-Net is a single player iPad game where you help classify coral reefs by painting 2D and 3D images of coral. The data you collect in the game trains NASA’s neural network to study coral reef health around the world.
