API

Free access to NASA's space imagery and scientific data

Overview

The NASA API offers RESTful access to a vast array of space-related data, including the Astronomy Picture of the Day (APOD), Mars Rover photos, Earth observation imagery, asteroid tracking, and celestial object details. Responses are in JSON format. Use cases include building educational tools for students, creating space-themed apps for enthusiasts, integrating high-res imagery into media projects, or researching asteroids and planetary data. Key endpoints like /planetary/apod deliver daily curated images with explanations, while /mars-photos/api/v1/rovers/curiosity/photos provides snapshots from Mars missions. A free API key is required for authentication.

Example Integration (JavaScript)

script.js JS


fetch('https://api.nasa.gov')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
