NASA's Image and Video Library: A Visual Archive of Space Exploration

NASA's Image and Video Library is one of the most comprehensive public archives of space imagery in the world, containing over 140,000 images, videos, and audio recordings spanning more than six decades of space exploration. From the earliest Mercury and Gemini missions through the Apollo Moon landings, the Space Shuttle era, and today's cutting-edge observations from the James Webb Space Telescope, this collection documents humanity's journey into the cosmos.

The library includes imagery from diverse sources: telescopes like Hubble and Webb that capture deep-space nebulae, galaxies, and exoplanets; planetary missions like the Mars rovers ( browse Mars photos) and Cassini at Saturn; Earth observation satellites ( see EPIC imagery); astronaut photography from the ISS; and documentation of rocket launches, spacecraft assembly, and ground testing. Most NASA images are in the public domain and free to download at full resolution for educational, editorial, and personal use.

Use the search bar above to find specific subjects — try queries like "Apollo 11," "Hubble Deep Field," "Mars surface," or "astronaut EVA." You can also filter by media type (image, video, or audio). For a daily curated experience, visit the Astronomy Picture of the Day.

NASA image: KENNEDY SPACE CENTER, FLA. - Nine-year-old Sofi Collis poses proudly with a banner displaying the names she selected for the Mars Exploration Rovers -- "Spirit" and "Opportunity" -- during a press conference. Participating in the press conference are, from left, Brad Justus, LEGO Co. senior vice president; Sofi Collis, third grade student from Arizona; Dr. John Marburger, science advisor to the President and director of the Office of Science and Technology Policy; and NASA Administrator Sean O'Keefe. The names Sofi suggested were selected from more than 10,000 student entries in an essay contest managed for NASA by the LEGO Company. NASA's twin Mars Exploration Rovers are designed to study the history of water on Mars. These robotic geologists are equipped with a robotic arm, a drilling tool, three spectrometers, and four pairs of cameras that allow them to have a human-like, 3D view of the terrain. Each rover could travel as far as 100 meters in one day to act as Mars scientists' eyes and hands, exploring an environment where humans are not yet able to go. MER-A, with the rover Spirit aboard, is scheduled to launch on June 8 at 2:06 p.m. EDT, with two launch opportunities each day during a launch period that closes on June 24.
