Chang'e 3 is a lunar exploration mission operated by the China National Space Administration (CNSA), incorporating a robotic lander and China's first lunar rover. It was launched in December 2013 as part of the second phase of the Chinese Lunar Exploration Program.
The spacecraft was named after Chang'e, the goddess of the Moon in Chinese mythology, and is a follow-up to the Chang'e 1 and Chang'e 2 lunar orbiters. The rover was named Yutu following an online poll, after the mythological rabbit that lives on the Moon as a pet of the Moon goddess.
Welcome to Earth! It's a planet having an iron core, with two-thirds of its surface covered by water. Earth orbits a local star called the Sun, the light of which generates the food supply for all the millions of species of life on earth. The dominant species on Earth is the human being, and you're one of the six billion of them! Humans have iron in their blood, and their bodies are composed of two-thirds water, just like the planet they live on. The physical composition of the Earth, its people and everything on it contains an electro-magnetic field which is not yet fully understood. Theories and legends about the origin of Earth, people and life itself abound, however they are not commonly discussed. The bulk of earth's people spend their time immersed in daily activities, leaving the big questions for later. "Who are we? Where did we come from? Where are we going? How will we get there?" Many religions and philosophies have attempted to answer these questions over the years, but so far none has given an answer that everyone on the planet can accept. In contrast to all the disagreement, the similarities among people on earth are far, far greater than any differences. Welcome again to Earth! Enjoy your stay, and try to stay calm.
