China's first lunar probe to land on the moon this weekend
China's first lunar rover is expected to land on the moon on Saturday, less than two weeks after it blasted off from Earth, CNN reported, citing Chinese media.
The landing will make China one of only three nations -- after the United States and the former Soviet Union -- to "soft-land" on the moon's surface, and the first to do so in more than three decades.
Chang'e-3, the unmanned spacecraft carrying the rover, is due to touch down on a lava plain named Sinus Iridum, or Bay of Rainbows, shortly after 3 p.m. GMT (10 a.m. ET) on December 14, according to the state-run Xinhua news agency.
On landing, Chang'e-3 will release Jade Rabbit (called Yutu in Chinese) -- a six-wheeled lunar rover equipped with at least four cameras and two mechanical legs that can dig up soil samples to a depth of 30 meters. The solar-powered rover will patrol the moon's surface, studying the structure of the lunar crust as well as soil and rocks, for at least three months.
The robot's name was decided by a public online poll and comes from a Chinese myth about the pet white rabbit of a goddess, Chang'e, who is said to live on the moon.
Weighing 140 kilograms, the slow-moving rover carries an optical telescope for astronomical observations and a powerful ultraviolet camera that will monitor how solar activity affects the various layers -- troposphere, stratosphere and ionosphere -- that make up the Earth's atmosphere, China's information technology ministry said in a statement.
The Jade Rabbit is also equipped with radioisotope heater units, allowing it to function during the cold lunar nights when temperatures plunge as low as -180°C (-292°F).
China has rapidly built up its space program since it first sent an astronaut into space in 2003. In 2012, the country conducted 18 space launches, according to the Pentagon.
