A Long March 3B rocket carrying a lunar probe blasted off at 2:23 a.m. from the Xichang Satellite Launch Center in Sichuan Province in southwestern China, the official Xinhua News Agency said.
With its Chang'e 4 mission, China hopes to be the first country to make a soft landing, which is a landing of a spacecraft during which no serious damage is incurred. The moon's far side is also known as the dark side because it faces away from Earth and remains comparatively unknown. It has a different composition than sites on the near side, where previous missions have landed.
If successful, the mission would propel the Chinese space program to a leading position in one of the most important areas of lunar exploration.
