interesting: if I correctly understand this abstract (the full paper is in Chinese), solar sailing attitude control was tested when CE-2 was stationed at L2http://zgkj.cast.cn/EN/abstract/abstract10662.shtmlQuoteMomentum Management of Chang'e-2 Satellite on L2 PointDAI Ju-Feng1, XU Hong-Bing2, CUI Yan2, XUE Rui1AbstractSince Chang'e-2 (CE-2) satellite entered the Lissajous orbit surrounding the Earth-Sun Lagrange point L2,the effect of jet uninstall was studied. A momentum management method by light pressure was given. The in orbit test shows that the Solar light pressure is strong enough to unload the momentum of CE-2 satellite, which is surrounding the L2 point. This method can substantially reduce the number of jet uninstall, and benefit the orbit maintenance of CE-2 satellite.

Anyone knows if this probe is still active?
China's Chang'e-2 a success: expert.
It has completed over 200 million kilometers flight and will continue to fly, returning somewhere closer to the earth around 2029
