Data from the Beijing Space Flight Control Center show that on the 28th, Chang'e-1's satellite equipment is working properly. It is in orbit 200 km away from the Moon, with orbital accuracy only slightly different (.0003) from the theoretical figure.
In addition, Director Tang Ge, from Beijing Space Flight Control Center, said in an interview on January 28th that the tracking data from Chang'e-1 indicate that China's deep space exploration flight control capabilities have made a breakthrough.
The Moon is a very irregular sphere, and satellites in orbit around different locations of the Moon experience relatively different gravitational pulls. A chapter has been written on China's flight control of lunar exploration satellites where there was once a blank page.
