The Chang'e-3, named after a Chinese goddess, is China's first spacecraft to make a soft landing on the moon. It includes a lander and a moon rover  called Yutu. The Chang'e-3 spacecraft is the second phase  China's lunar rogramme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang'e-1 and Chang'e-2 spacecraft in 2007 and 2010. The launch of Chang'e-3 was successful. The Chang'e-3 is one of the most difficult tasks in China's space programme, the news says. The news adds that exploring the universe  and seeking peaceful use of space are dreams of Chinese for thousands of years. With a lander and the moon rover Yutu, Chang'e-3 soft-landed  on the moon at 9:11 p.m. Saturday. Yutu later separated  from the lander and ran to the moon surface earlier Sunday. China has chosen the name Yutu for its first moon rover, after a worldwide online vote  attracted people to come up with names. In Chinese folk tale, Yutu is the white pet rabbit of Chang'e, the moon goddess. Chang'e took her pet and flew towards the moon. She became a goddess and has lived there with the white animal ever since. From this passage, how many spacecraft have flown to the moon successfully.
