52-ST_image_23-08-06_10_42UTC_H.jpg"Satellite Craters"62 visiteCaption ESA originale:"This image of the Lunar Surface was taken on 23 August at 12:42 CEST (10:42 UT), by the star tracker (attitude camera) on board ESA’s SMART-1, from a distance of 165 Km above the Moon Surface. SMART-1 was travelling at a speed of 1,93 Km/sec.
The two craters visible on the image are 'satellite' craters to the Neumayer Crater. Satellite craters are identified by the name of their parent crater and an additional letter.
On the star tracker image the crater with the sharp rim is called Neumayer "M" (located at a Latitude of 71,6° South and a Longitude of 78,5° East) and the one with the smooth rim is called Neumayer "N" (at a Latitude of 70,4° South and a Longitude of 78,7° East).
The image is slightly smeared as the spacecraft is moving at high speed and at low altitude. This image was taken as a test, which means the spacecraft pointing was not optimised for taking images with the star tracker".

50-Smart-1_25_August_1348UTC_H.jpgLunar Limb and Stars64 visiteCaption ESA originale:"This image of the Lunar Surface was taken on 25 August 2006 at 15:48 CEST (13:48 UT) by the star tracker (attitude camera) on board ESA's SMART-1, from a distance of 744 Km above the Moon surface.
The spacecraft was travelling at a speed of 1,6 Km/sec..
Remarkably, at the time the image was taken the star tracker was still producing valid attitude samples based on the few stars that are visible in the image.
This image was taken as a test, meaning that the spacecraft pointing was not optimised for star tracker imaging.
The Moon features on the photo still have to be identified".

41-Mezentzev Crater.jpgCraters Mezentsev, Niepce and Merril60 visiteThis image was taken by the Advanced Moon Imaging Experiment (AMIE) on 16 May 2006. The imaged area is centred at a Latitude of 73° North and a Longitude of 124° West, on the Far-Side of the Moon.
Normally, the AMIE camera is pointed straight down at the Lunar Surface, in the Nadir pointing mode. In this image, AMIE was pointed towards the horizon, showing the Lunar Surface in an oblique view.
The largest craters in this image are Mezentsev, Niepce and Merrill. Mezentsev is an eroded crater 89 Km in diameter and centred at 72,1° N, and 128,7° W.
A smaller cup-shaped crater resides inside Mezentsev. Niepce and Merrill both have a diameter of 57 Km and are located at 72,7° N-119,1° W and 75,2° N and 116,3° W, respectively.
Mezentsev Crater is named after Yourij Mezentsev, a Soviet engineer (1929 - 1965) who was one of the first people to design rocket launchers, while Joseph Niepce was the French inventor of photography (1765 - 1833); Paul Merrill was an American astronomer (1887 - 1961).

40-Jacobi Crater.jpgJacobi Crater (HR)57 visiteThis HR image was taken by the advanced Moon Imaging Experiment (AMIE) on 18 March 2006 from a distance of about 578 Km from the Moon's surface, with a ground resolution of 52 mt per pixel. It shows part of crater Jacobi in the Moon's Southern Hemisphere. The western crater rim can be seen on the left edge of the image. The imaged area is centred at a Latitude of 56,5° South and a Longitude of 10,9° East, with a field of view of 27 Km. North is up.
Crater Jacobi itself is much larger than this image - 68 Km in diameter - with the imaged area only showing about 1/5th of the crater floor area. The crater is centred at a Latitude of 56,7° South and a Longitude of 11,4° East. The single prominent crater to the upper left of the image centre is Jacobi "W", with a diameter of only 7 Km.
Peculiar surface structure can be seen in the lower left part of the image, and indicates several heavily eroded big-sized craters.
SMART-1 resolution at high solar elevation angle allows for the detection of eroded structures buried under more recent layers, giving a window on the past evolution of the Moon.
The crater is named after the German mathematician Karl Gustav Jacob Jacobi (1804 - 1851), who worked on elliptic functions and was active in the field of celestial mechanics

35-Lomonosov Crater-AMI_EAE3_001856_00042_00038.jpgLomonosov Crater79 visiteCaption ESA originale:"This image, taken by the Advanced Moon Imaging Experiment (AMIE) on board ESA’s SMART-1 spacecraft, shows crater Lomonosov, on the Moon’s Far (or "Dark") Side.
AMIE obtained the image on 30 January 2006 from a distance of about 2100 Km from the surface, with a ground resolution of 190 mt per pixel. The imaged area is centred at a Latitude of 27,8º North and a Longitude of 98,6º East.
Crater Lomonosov is a nice example for a large crater (92 Km of diameter) which was filled by lava after the impact, thus exhibiting a flat floor. The terraced walls indicate 'slumping', that is sliding of the rocks downwards due to gravity after the end of the impact. The small craters inside Lomonosov are the result of impacts into this lava floor which happened after the formation of Lomonosov".

28-Zucchius-2.jpgThe Central "Peak" of Zucchius Crater (HR - extra detail mgnf)98 visiteQuesto extreme detail mgnf del rilievo anomalo di Zucchius non aggiunge molto alle nostre considerazioni e ne siamo consapevoli; tuttavia, per chi ha un "occhio" uso alle Stranezze Lunari (e non solo...), la regolarità sostanziale della forma più chiara (che possiamo chiamare "basamento") ed il rilievo circolare che lo sovrasta - se si osserva con attenzione - non Vi potranno sfuggire.
Certo, da qui a dire che si tratta di un rilievo "artificiale" ce ne passa e, credeteci, nessuno di noi sta inferendo nulla del genere. L'unico dettaglio che desideriamo sottoporre al vaglio critico dei Lettori attiene la curiosa (ed apparente) "regolarità" del rilievo ripreso e la costante "deficienza" (nel senso di "mancanza", ovviamente...) delle Agenzie Spaziali le quali, tutte le volte in cui ci si imbatte in una possibile Anomalìa (da Cydonia, a Giapeto a Zucchius etc.), producono immagini di qualità indecente.
Ecco: perdonateci l'ironia, ma forse quest'ultima riflessione costituisce la vera - e la più grande - "stranezza" di qualsiasi Programma Spaziale!

28-Zucchius-1.jpgThe Central "Peak" of Zucchius Crater (HR)112 visiteL'immagine, nonostante gli sforzi dell'ESA e nonostante l'Alta Risoluzione, resta mediocremente sfuocata. Tuttavia, sebbene la certezza non la si può avere, riteniamo di poter dire, con un discreto margine di certezza, che esiste un oggetto anomalo proprio sulla sommità (o nei suoi pressi) di una delle collinette che caratterizzano l'area centrale del Cratere Zucchius. L'oggetto (se seguissimo la Scuola di Hoagland potremmo già parlare di "costruzione") pare avere una base rettangolare e, su questa base (e leggermente alla Sx dell'Osservatore) pare esserci un ulteriore rilievo di forma circolare.
Un'immagine brutta, ripetiamo, ma intrigante ed enigmatica. Da studiare.

22-ReinerGamma-Maps.jpgReiner Gamma: a Moon "Magnetic Anomaly" (1)122 visiteCaption ESA originale:"The bright albedo feature called Reiner Gamma, is located in the Oceanus Procellarum on the near side of the Moon.
From ground-based observations, this feature was first mis-identified as a crater. Spacecraft orbiting the Moon, however, revealed its true nature: Reiner Gamma is totally flat and consists of much brighter material than the surrounding dark mare. Only three features like this exist on the Moon. Apart from Reiner Gamma on the lunar near side, there are two more on the lunar far side, not visible from the Earth. The last two features are exactly opposite of the large impact sites which created Mare Imbrium and Mare Orientale. It is assumed that these features formed due to the reflection of the shock wave of these impacts on the opposite side of the Moon.
The area also coincides with a strong magnetic anomaly".

15-Bond&Mayer Craters.jpgBond-Mayer Crater96 visiteAn image of craters Bond - after an American Astronomer - (large feature marked by two smaller crater on left of image) and Mayer - after a Czech Astronomer (large isloated crater on lower right) located in Northern Central Region of the Moon, near Mare Frigoris. The image is a composite of 5 AMIE images acquired on 5/6 February 2006, from altitudes ranging between 2685 (bottom of the composite) and 2709 Km (top). Each individual snapshot, taken with the AMIE clear filter, is a square of side about 135 Km. The whole composite covers approximately 270 Km. The outer rim of the original Bond Crater has been eroded and reshaped, and now it basically consists of an outline of hills and mounts.
The interior floor is relatively flat in comparison with the rim region, although there are sections of rough terrain near the northern rim. In the centre of the walled plain is a rille that runs toward East.
To the southeast of this formation is Bond-B, a circular, simple bowl-shaped crater.
