Luna-03.jpgThe Yutu-2 Rover from LRO77 visiteI dati sino ad ora in nostro possesso sono stati raccolti nel Cratere Von Kármán a partire dal 3 gennaio 2019 quando la navicella spaziale cinese Chang'e 4 è atterrata al suo interno, così diventando la prima Navicella Spaziale ad atterrare dolcemente sul lato (a noi) "nascosto" della Luna . Il Sito ha un valore simbolico oltre che scientifico. Theodore von Kármán (1881-1963) è stato il consigliere di dottorato di Qian Xuesen , il fondatore del Programma Spaziale Cinese.
Il 4 febbraio 2019, la IAU ha approvato il nome del sito di atterraggio come Statio Tianhe . Il picco centrale del Crater Von Kármán, a nord-ovest del Sito di atterraggio, è stato chiamato Mons Tai . Sono stati anche nominati tre piccoli crateri: Hegu, a sud del Landing Site, Zhinyu a Ovest e Tianjin a Nord-Est.MareKromium

Luna-00.jpgVon Kármán Crater79 visiteThe Chinese "Chang'E-4" (CE-4) spacecraft achieved the first successful soft landing on the Floor of the Von Kármán Impact Crater located in the Nort-Eastern portion of the South Pole-Aitken (SPA) Basin on the Moon (Far-Side). Here, through analysis and processing of the dual-channel Lunar Penetrating Radar (LPR) data, the shallow regolith structure and deep Geological Strata below the Landing Site are exposed. The high-frequency data (CH-2, 500 MHz) show that the Von Kármán Crater underwent remodeling because of ejecta from multiple craters within a thickness of about 40 meters.
Nota: questa Galleria è dedicata agli Appassionati dell'Esplorazione Spaziale (ivi: Lunare) e non intende essere un "tributo" alla Cina ed alla sua Agenzia di Bandiera. Il motivo è semplice: i risultati delle Missioni Spaziali Cinesi sono sempre avvolti in coltri di fitta nebbia, le immagini sono difficili da reperire e quelle "(diciamo) pubbliche" sono scadenti e sostanzialmente insignificanti. Probabilmente anche la "Propaganda" ha dei limiti...palesi.
Note: this Gallery is dedicated to the Space (here: Lunar) Exploration "lovers" and does not mean at all to be a "tribute" whatsoever to the Republic of China and its Space Agency (CSA). The reason of this premise is very simple: the results of the Missions carried out by the CSA are always wrapped in a thick cloud of fog; the images (frames) are hard to find (unless the CSA releases them "willingly"...) and the ones, let's say, "public" are shoddy and meaningless. We therefore believe that even the "propaganda" must have its own undisguised limits...MareKromium

Kaguya-035-Lunar_Terrain-tc_035_1_l.jpgFrom Light to Darkness: Lunar Terrain255 visiteCaption JAXA:"This image was obtained using TC cameras of the Kaguya Probe about 10 minutes prior to the KAGUYA's controlled impact on the Moon. Observation location was between Craters Drygalski and Ashbrook (approx. 83° South and 260° East); the probe's altitude was about 18.500 meters".MareKromium

Kaguya-037-Marius_Hill-tc_039.jpgMarius' Hills Region: possible Skylight288 visiteCaption JAXA:"Images of a possible 65 mt diameter Lunar Lava Tube Skylight in the Marius Hills District taken by SELENE Terrain Camera (TC) and Multi-band Imager (MI).
(Upper left frame) Overview of the Region (TC, 20 May 2008; 12,9 to 14,4° North Latitude and 55,7 to 57° West Longitude - approx. 35 x 45 Km.
(Upper right frame) The Skylight (a.k.a.: the "Marius Hills' Hole"; MHH) at 303,3° East and 14,2° North, in a Rille ("Rille A").
(Lower four frames) Enlarged TC and MI images of MHH (1st and 2nd frame from the left are TC images from 20 May 2008 and 21 January 2009; 3rd and 4th are MI images from 17 March 2009 and 13 April 2009).
Arrows indicate the directions of Solar Illumination (I) and the view vector from the camera (V).
The depth of MHH has been estimated to be 80 to 88 meters. If there exists a Lava Tube under MHH, its maximum width can be wider than a few hundred meters".MareKromium

LRO-2501-Oceanus_Procellarum.jpgLunar Landslide in an Unnamed Crater of Oceanus Procellarum66 visiteA key part of the LROC science investigation is the imaging and analysis of fresh, Copernican-aged Craters (such as Craters younger than 1,1 Billion Years), like this small (6-Km diameter) example at the edge of Oceanus Procellarum, West of Balboa Crater.
The LROC team has seen a variety of landforms related to these important lunar features. For example, a Landslide on the Crater wall partially covers the solidified impact melts on the floor. The Landslide clearly happened after the Crater initially formed; the materials were likely dislodged by seismic shaking from nearby smaller impacts.
These young, fresh craters preserve an vital record of the impact process.
Where does ejecta come from? How much impact melt is produced? How thick is ejecta? What is the importance of self-secondary impacts?
These are only some of the important scientific questions that lunar scientists can address by studying these craters.
As geologic time progresses, the pristine features in fresh craters are worn down by impacts of all sizes. Understanding young craters help geologists piece together the history of ancient degraded craters, an understanding particularly useful for planning future human missions to the Moon. The best way to explore fresh craters like this one, of course, would be with Astronauts.
However, until humans return to the Moon, lunar geologists will analyze images like this for clues, as well as comparing the landforms like the one visible here with other craters on the Moon, Mars, and impact structures on Earth.MareKromium
