China completed the first soft landing on the moon’s surface in 37 years Saturday, becoming only the third country to pull off the feat.

State television showed scientists in white and pale-blue coats applauding, shaking hands and congratulating each other after the craft, Chang’e 3, landed safely at 9:12 p.m. local time. It also showed photographs of the moon’s surface beamed back from the craft.

The landing marked a significant advance in China’s space program and a step toward its ambitions of one day following the United States in mounting a manned lunar mission.

On Sunday, a six-wheeled rover named Yutu, or Jade Rabbit, is scheduled to emerge from the landing vehicle and begin a three-month-long mission to explore the moon’s surface.

The moon lander, which weighs more than a ton, landed in the right eye of the lunar feature dubbed the Man in the Moon, in a large and relatively flat volcanic crater known as the Sinus Iridum, or Bay of Rainbows. Its rockets shut off when it was about four yards above the surface, and the craft fell the remaining distance.

The landing craft, which is designed to remain in place and operate for a year, carries a telescope that will survey space from the moon’s surface and an ultraviolet camera that will observe the Earth and the plasmasphere surrounding it.

The rover, which will roam around for three months, will not only analyze the topsoil in a previously unexplored region of the moon but also will collect through its radar system information about the lunar surface to a depth of 100 yards.

Dean Cheng, a senior research fellow at the Heritage Foundation in Washington, said the radar system, in particular, would yield useful data.“China has said that to be a global power, you do have to contribute to the global pool of scientific knowledge,” he said. “The moon, for all that it is our closest celestial neighbor, is rather unexplored. . . . China is, in fact, contributing to the pool of lunar knowledge.”

The rover will be powered by solar panels during the lunar day, and atomic energy storage batteries will keep it warm and prevent its electronic systems from freezing during the lunar night, which lasts the equivalent of two weeks on Earth and can see temperatures as low as 180 degrees below zero Celsius, the equivalent of 292 degrees below zero Fahrenheit.

“Compared to the last century’s space race between the United States and the former Soviet Union, mankind’s current return to the moon is more based on curiosity and exploration of the unknown universe,” Sun Huixian, the project’s deputy chief engineer told the official Xinhua News Agency. “China’s lunar program is an important component of mankind’s activities to explore the peaceful use of space.”

The lander and the rover are named for a Chinese myth about a woman named Chang’e who swallowed magic pills and took her pet rabbit, Yutu, to the moon, where she has lived as a goddess ever since.

“Though people have discovered that the moon is bleached and desolate, it doesn’t change its splendid role in Chinese traditional culture,” Zhang Yiwu, a professor at Beijing’s Peking University, told Xinhua.

China hopes to mount another mission to the moon in 2017 that would collect rock and soil samples. It also hopes to launch a space station by about 2023 and eventually, perhaps, establish lunar bases and send missions into deep space. Its space program has the advantage of consistent funding and top-level political support, and the successful moon landing will ensure that continues, Cheng said.

“This was a big step,” said Joan Johnson-Freese of the U.S. Naval War College in Newport, R.I. “It makes [a manned mission] far more feasible.”China’s space program has established itself as a significant player globally, Johnson-Freese said. “It wants to work with developed countries to show it is a major space nation,” she said, adding that China’s program has also encouraged other countries, such as India, to invest more in space exploration to show they are not falling behind in the technological race.The program is a source of deep national pride and was widely celebrated Saturday by users of the weibo microblogging sites.

“At this moment my eyes are full of tears, I’m proud of my motherland, I’m proud that I’m Chinese,” wrote Huanranbingshi2000.

I hope China can continue the exploration of the moon for science.
The USA stopped doing that about the time former president Reagan finished closing the deal to
sell the USA to a few ultra rich capitalists. Since that time privatization has left the US to concentrate
on finding ways to sell tickets to the moon to the ultra rich for their amusement.
If capitalism promotes innovation and creativity then why aren't scientists and artists the richest people in a capitalist nation?

Well done for the Chinese space program
Stan, you're holding a gun to God's head. I can't think of a metaphor that's better than this.

So does that make the moon an integral part of China since ancient times now ?
Spreading magic around the world since 2007.
