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

More images:

Is it me or does our Moon seem somewhat boring compared to Jupiter and Saturn's oddballs?

I am not sure. Some aspects of it seem really interesting...the volcanic domes for instance. I think a lot of it is the old saying "familiarity breeds contempt." The moon is the world we are most used to (other than the Earth). We have had higher resolution images of half of its surface for decades (and if you could seeing as much detail visually for over two centuries) than we have of most of the surfaces of most outer planet satellites. And of course we didn't have "from space" view of earth until half way through this century. So the moon, viewed from above, is the most familar thing to us. I think as a result of this, we think of it as defining normal or ordinary. Really, I can't think of another world like it.

What kind of resolution can we expect?

"The camera itself has a medium field of view of 5.3 degrees by 5.3 degrees and provides a high-resolution image at 27 metres per pixel from an altitude of 300 kilometres. The image measures 1024 x 1024 pixels. "

Overall I have been unimpressed with the resolution of the SMART-1 images. I know an amateur astronomer who is literally taking higher-resolution images from his backyard with a C8.

What I meant to say was not so much that the actual resolution was higher but just that they look much sharper. This guy processes the heck out of his images and gets resolutions fairly to close to his theoretical maximum. The SMART-1 images just look a bit fuzzy to me. -------------------- ----------------------------------------------

It may be the use of compression. It has 1024x1024 CCDs, and I have yet to see an image released at that resolution. So it is also possible the releases are degraded, or that these are pre-mapping images that have been binned. Whatever the case, at 27 m/pixel, there should eventually be some spectacular mosaics.

"Unfortunately, on starting the calibration program, an anomaly occurred on board. On the night of 28 February the EP engine unexpectedly fired for about 11 hours. The cause was later traced to a recent change in the software and was subsequently corrected. The consequence of this error is a delay in the completion of the instrument lunar commissioning of a couple of weeks. On 12 March, the ESOC Flight dynamics team commanded the spacecraft to perform an equivalent burn to compensate the unintentional one. By the start of April all the instruments should be tested and calibrated and ready to start collecting valuable science data. " Ouch, hopefully this will not shorten the extended mission. |

Anyone know where are promised HR images of LEM sites? SMART should have taken them many weeks ago...

There's something on the ESA website about planned imaging of the sites later, at v.low altitude I believe I thought the same thing as you at first. Doug |
