| Vodcast/ Podcast | NASA Connect -- Ancient Observatories: Timeless Knowledge | The first video segment explains the foundations of astronomy, the seasons and the how the Earth moves relative to the Sun. The second segment explains how the height of the Sun relates to the growing seasons and the length of daylight, and how ancient Egyptian and Greek cultures used astronomy in their lives. The third segment shows how the Navajo used structures to track the Sun in the sky. The fourth segment describes the ancient Mayan civilization and their accomplishments. |
| Animation | Hubble Space Telescope Slews | The Hubble Space Telescope is pointing north at a blank patch of sky above the Big Dipper. Next, shown in orbit, Hubble is slewing to point at the southern skies in the direction of the constellation Tucana, near the south celestial pole. This is an artist's conception, and not a view from the Hubble Space Telescope. |

| Interactives | Build Your Own Space Mission | This online game allows students to design their explorer, build their spacecraft and study a planet or moon in our solar system. It blends kid-friendly graphics with real space images. |
| Animation | A Day on Mercury | Since Mercury rotates exactly three times for every two orbits, a day on Mercury would be quite different from a typical Earth day. In this animation you can experience this typical Mercurian day. |
| Animation | The Sun on Mercury | Because Mercury is the closest planet to the Sun, the Sun would appear much larger than it does on Earth. In addition, Mercury's elliptical orbit is more elongated than that of Earth, so the planet's distance from the Sun changes dramatically over the course of each orbit; the Sun would appear to grow larger as Mercury gets closer to it, and to shrink as the planet moves farther away. |
| Network | Solar System Ambassadors | The Solar System Ambassadors is a nation-wide network of volunteers who are trained to communicate the excitement of NASA's space exploration missions and recent discoveries to people in their local communities. |
