24-Mare Humorum-1.jpgMare Humorum (1)81 visiteThis sequence of images, taken by the advanced Moon Imaging Experiment (AMIE) on board ESA's SMART-1 spacecraft, shows an area on the near side of the Moon, at the edge of the Mare Humorum basin.
AMIE obtained these raw images on January, 13th, 2006 from a distance ranging between 1031 and 1107 Km from the surface, with a ground resolution between 93 and 100 mt per pixel.
The imaged area is located at Longitude 45,7º West and Latitude between 30,5º and 24,5º South. The field of view of each single image is about 50 Km.

24-Mare Humorum-2.jpgMare Humorum (2)70 visite...La voglia di commentare questi poveri frames (poveri da svariati punti di vista...) messi a disposizione dall'ESA è forte ma, dato che il commento, in casi come questo, diventerebbe prima ironia e poi sarcasmo, riteniamo più giusto e saggio tacere.
Anzi no, una cosa va detta: se questi frames (assieme ai pochi altri messi a disposizione del Pubblico da parte dell'Agenzia Spaziale Europea in questi mesi) sono il risultato reale del mapping iper-dettagliato della Luna che SMART-1 avrebbe dovuto eseguire, allora ci tocca dire e ribadire che l'ESA ha ancora tantissima strada da percorrere prima di arrivare a produrre qualcosa di decente.
Se invece questi miseri frames sono solo una porzione del lavoro svolto da SMART-1 (come noi riteniamo), ci piacerebbe allora sapere come mai anche la "pacifica ed indipendente" Agenzia Spaziale Europea "gioca a nascondino" con le immagini che arrivano dallo Spazio.

32-MareHumorum.jpgMare Humorum61 visiteThis mosaic of three images, taken by the advanced Moon Imaging Experiment (AMIE) on board ESA's SMART-1 spacecraft, shows Mare Humorum on the Moon.
AMIE obtained the top frame on 1 January 2006, from a distance of 1087 kilometres from the surface, with a ground resolution of 98 metres per pixel. The remaining two frames were taken on 13 January 2006, from a distance of about 1069 (centre) and 1050 kilometres (bottom) from the surface, with a ground resolution of 97 and 95 metres per pixel, respectively.
The area shown in the top image is centred at a latitude of 40.2º South and longitude 25.9º West; the centre image is centred at a latitude of 40.2º South and longitude 27.3º West; the bottom image is centred at a latitude of 40.2º South and longitude 28.8º West.
Mare Humorum, or 'Sea of Moisture', is a small circular mare on the lunar nearside, about 825 kilometres across. The mountains surrounding it mark the edge of an old impact basin which has been flooded and filled by mare lavas. These lavas also extend past the basin rim in several places. In the upper right are several such flows which extend northwest into southern Oceanus Procellarum.
Mare Humorum was not sampled by the Apollo program, so its precise age could not been determined yet. However, geologic mapping indicates that its age is in between that of the Imbrium and the Nectaris basins, suggesting an age of about 3.9 thousand million years (with an uncertainty of 500 million years).
Humorum is filled with a thick layer of mare basalt, believed to exceed 3 kilometres in thickness at the centre of the basin. On the north edge of Mare Humorum is the large crater Gassendi, which was considered as a possible landing site for Apollo 17.
Mare Humorum is a scientifically interesting area because it allows the study of the relationships among lunar mare filling, mare basin tectonics, and global thermal evolution to the major mascon maria – regions of the moon's crust which contain a large amount of material denser than average for that area (Solomon, Head, 1980).
Past studies (Budney, Lucey) revealed that craters in the mare Humorum sometimes excavate highland material, allowing to estimate the thickness from below the mare cover. Thanks to this, it was also possible to determine that the ‘multiring’ structure of the Humorum basin has a diameter of 425 kilometres (results based on the US Clementine global topography data).
In general, the chronology of lunar volcanism is based on the analysis of landing site samples from the Apollo and Luna missions, from the study of the relationship between the stratigraphy (layering of deposits) in different regions, and from the analysis of lunar craters – how they degraded over time and how their distribution in number and size varies over the Moon’s surface. From crater statistics, in the year 2000 Hiesinger and colleagues found that in Humorum there was a peak of eruptions at about 3.3-3.5 thousand million years ago.

APOLLO 17 AS 17-2444.jpgAS 17-2444 - Mare Imbrium & Copernicus Crater53 visiteThis oblique view across southern Mare Imbrium looks toward Copernicus, the large crater near the horizon. The distance from the lower edge of the picture to the center of Copernicus is 400 km. The mountains at the edge of Mare Imbrium are the Montes Carpatus, and the large crater near the center of the picture is Pytheas, almost 19 km in diameter. Copernicus is one of the youngest of the Moon's large craters. It is visible from Earth, even without the aid of a telescope because of its bright ejecta blanket and its extensive bright rays. The many chains and clusters of small irregular craters and the many bright streaks or rays extending across Mare Imbrium are caused by the secondary impact of debris ejected from Copernicus. The viewing angle accentuates the radial pattern of the secondary impact features. The Sun angle is sufficiently low to show their relief, but high enough to show the contrast between the bright streaks and the normal dark mare surface. As in figure 124, herringbone ridges point toward the primary crater, and the flaring sides of the secondary craters point away from it. The arrow midway between Copernicus and the left edge of the photograph points to a less common pattern of secondary craters; these are concentric to Copernicus.
