The pioneering Chinese lunar orbiter crashed onto the lunar surface at 0813 GMT on March 1, 2009. Its impact was in northeastern Mare Fecunditatis near the small crater Messier J (bottom right margin of image). There was apparently no advance warning and thus no chance for observers to look for an impact flash or plume. This would have been more than just an exciting event because imaging a collisional flash from a projectile of known mass, velocity and impact point would have provided a calibration for the ongoing imaging of meteorite impact flashes on the Moon, and possibly be of use to planners preparing for the impact of LCROSS in a polar crater. The Chang'e-1 mission demonstrated that China can build and successfully fly a spacecraft to the Moon, but the paucity of scientific results, so far at least, makes me wonder if it was just an engineering test. I hope the Chinese will ultimately release thousands of images, high resolution topographic charts and all the other data their instruments collected.
