摘要

THE ONGOING CE-4 MISSION NSR:How is the current condition of the CE-4 lander and Yutu-2? Wu:Their condition is rather good.The design lifetime of the CE-4 lander and Yutu-2 (the rover) is six and three lunar days,respectively.(A lunar day lasts for about 28 Earth days,including a lunar night of about 14 Earth days.) Now they are beginning their fifth lunar day of work,which means that Yutu-2 has already exceeded its design life and the lander is approaching its design life.Yutu-2 has travelled on the moon for about 180 m.The instruments on the lander and Yutu-2 are operating well and collecting data about the topography,geological structure,mineral composition and space environment of the far-side of the Moon.
