The sun-centered solar system, whose sharp and vivid images have been provided by various space missions, has created daunting challenges for students, teachers, educators, and researchers in drawing up major solar system projects.

The main missions that provided the latest information about the solar system are Mariner 10, Viking 1 and 2, Voyager 1 and 2, Magellan, Galileo, Hubble, Space Shuttle, Mars Pathfinder, Mars Global Surveyor, Near Earth Asteroid Rendezvous, Cassini, and Apollo.

It is inevitable that Man, with his legendary inquisitiveness and resourcefulness, will break free of all earthly boundaries. As more information concerning the solar system becomes available, there will be an increase in armchair astronauts as well as budding space enthusiasts. Teachers inspire young minds; they express relative size and distance between the planets through virtual and visual projects, classroom projects, art projects, and models.

The wide variations between distances of planets from the sun and the sheer enormity of the solar system are best impressed upon young minds with the help of a walk-in model of the solar system. The motion of planets and other celestial bodies in their orbits is due to the force of gravitation of the sun on them.

The USGS Astrogeology Research Programme features planetary imagery and research and helps portray Earth and Space Sciences in a fun way, including information about space weather, global space physics, and a real-time movie of current solar activity.

Projects on the solar system, our neighborhood in our home galaxy, have been dovetailed in different angles of the trajectory and according to the disposition of the Sun, Mercury, Venus, Earth, Mars, Moon, Jupiter, Saturn, Uranus, Neptune, Pluto, comets, and asteroids. Such visual tours of the solar system provide a scintillating view of the Milky Way, including the solar system.

The various possibilities for interesting space projects grow by leaps and bounds as more secrets are unfolded by space missions.
