A Chinese spacecraft successfully entered a stable lunar orbit on Monday, according to government sources. The unmanned service lab is in an eight-hour orbit around the moon, which brings it within 125 miles of the lunar surface at its closest point, and as far out as 3,293 miles at its furthest away point.
China’s moon mission first arrived in orbit a couple of months ago. The orbiter flew back to Earth in November, and the service module was moved into a position in into sync with Earth’s orbit.
