What are space probes?


Space probes are unmanned spacecrafts equipped and designed to retrieve scientific information about the solar system. This information is transmitted by radio back to earth. It includes data regarding the atmosphere, temperatures and surface conditions of planets.

Space probes are designed to conduct scientific experiments and explore the solar system. Most space probes are designed not to return to planet Earth and many have landed on various planets in the solar system. Some space probes take pictures of a planet as they fly past, which assist scientists in gaining a better understanding of the positions of different types of planets in our solar system.

Certain space probes orbit a specific planet for long-term observation. The information retrieved from these space probes is essential to scientists who study the changes in weather patterns that exist on other planets in the Earth’s solar system. This type of information is vital in assisting with plans for space missions such as those to Saturn and Mars.

The space probe known as the Cassini is the most expensive and biggest probe ever used for scientific exploration. It was launched in July 2004 to study Saturn and to observe the planet's many moons and ring systems.
