According to moondaily.com China plans a (unmanned) moonlanding for 2013.
The article contains an image of a sample-return probe taking off from the moon which indeed looks a lot like a (Soviet) Y8E derived vehicle. If this is true, my earlier remark here that this landingsite might be selected for its option to fly a direct ascent trajectory back to earth seems to make sense, they might indeed be planning to attempt a sample-return mission with a moonlanding in the vicinity of the present crash-site. Regards, Geert. |

Does anyone have any insights into the rover deployment sequence?
Early drawings showed it mounted on the side of the lander (LRV-style) and pivoting onto the trackway about 75 cm from the surface, with a shallow incline. A presentation last year by CLEP chief scientist Ouyang Ziyuan seemed to show a fork-lift truck type lift assembly to deliver the rover from atop the lander to the surface. A report last weekend on CNTV showed the rover "walking the plank" Wile E. Coyote-style, with the trackway suspended 2 meters above the surface and ending in mid-air. Clearly, not all depictions are to be trusted! However, the final configuration seems to have the rover mounted atop a circa. 2-meter-tall main bus, with a vertiginous trackway descending in only one direction. Does this not break at least two cardinal rules of rover delivery? 1) Keep your centre of mass low. 2) Give yourself an alternative exit route in case a boulder blocks one pathway. |

Does anyone have any insights into the rover deployment sequence? This video, posted today to YouTube, shows a good view of the set-up at 0:30. The way I understand it, the tracks on the side of the lander extend out and unfold in such a way where the rover will be able to drive off the top. https://www.youtube.com/watch?v=dEd0TljENBc -------------------- -- Hungry4info (Sirius_Alpha)
