SMART-1 is approaching its operational orbit. ESA has released some images of the Moon on this page:

Preliminary impact data including a site - on the far side, but they say it might be changed so they can monitor it.
Phil Perilune of 0 km * Date = 2006/08/17 ~11:00 (uncertainty ~ 1 day) * Radius of perilune = 1738 km * Radius of apolune = 5096 km * Inclination = 91.4° * Right ascension of ascending node = 239.7° * Argument of perilune = 217.5° * Sun-moon-perilune angle = 87.0° * Earth-moon-perilune angle = 134.4° * Longitude of perilune = 174.4° * Latitude of perilune = -37.5° * +X to Earth angle when +Z to velocity at perilune = 105.0° * Velocity at perilune = 2.051 km/s * Perilune radius change per orbit -1.888 km/rev It should be noted that the impact date of 17 August 2006 assumes no further changes are made to the spacecraft orbit. It is possible that this date will change to accomodate specific requests to enable monitoring of the impact from Earth. -------------------- ... because the Solar System ain't gonna map itself.

I, too, thought that the ESA Press Release was a classic bit of ESA-Speak, but as Phil points out it was - strictly - true. Well, apart from the 'push-frame' vs 'push-broom' question, anyway! I wonder when, if SMART-1 reaches a perilune of 0km in mid 2006, ESA will actually announce EOM? 2007? Perhaps they'll claim a new record for *surface* push-broom operations... ...it's said to be quite dusty down there!
On a less silly note, I'm intrigued by the commencement of this new imaging mode at what is by any standards a late stage of the mission. Reading the ESA PR, it looks to me like push-broom/frame is actually quite hard on the imaging system - am I right in this?
