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. |

Separation is really spectacular, even though I suspect that, initially, the glare is due to a solar reflection and not to the probe thrusters! ![]() I don't think that intense brightness is solar flare. The craft apparently has 8 x 150N thrusters in addition to the small attitude control thrusters of 10N each, plus the main descent engine. " These eight 150N thrusters are likely used for smaller Trajectory Correction Manoeuvres during the Earth-Moon transfer and small orbital adjustments (& possibly during LOI and landing). " Chang'e 3 technical description I think the flare is us seeing those intermediate thrusters ensuring adequate separation of the probe from the rocket stage. |

I think the flare is us seeing those intermediate thrusters ensuring adequate separation of the probe from the rocket stage. No - the way the flare appeared - from the one, sunlit side of the spacecraft as both spacecraft and third stage entered into sunrise - it was lens-flare of a specular reflecting on gold MLI. |
