Channels-Inverted_Channels_in_Arabia_Terra-PIA03643-02.jpgInverted channels of Arabia Terra (2 - Original NASA/MGS/MSSS b/w Frame)61 visiteOriginal caption:"This MGS-MOC image shows a somewhat sinuous, nearly flat-topped Ridge, located in Eastern Arabia Terra. The ridgetop was once the Floor of a Valley, perhaps carved by running water. The Valley Floor, or material that covered the Floor, was more resistant to erosion than the surrounding rock into which the Valley was cut. Thus, over time, the Valley disappeared and its Floor was left standing high as a Ridge. Inverted Valleys are common on Mars, but they also occur on Earth".
Location near: 10,8° North Lat. and 313,2° West Long.

Channels-Bahram_Vallis-M1000914-00.jpgBahram Vallis' River and Landslides: the Area (Original NASA/MGS/MSSS b/w CTX Frame)55 visiteUn rapido avvicinamento ad una curiosa 'valanga di fango' che ha molto ben visibilmente alterato una modesta sezione del letto di questo antico fiume Marziano.
Nessuna Anomalia, solo una serie di tre bellissime immagini.

Channels-Uzboi_Vallis-A-M1100709.jpgChannels's Network in Uzboi Vallis (1 - CTX Frame)57 visiteSe provate a riguardare le immagini ESA relative alla Sonda Huygens mentre scende verso la superficie di Titano, troverete senz'altro delle analogie con questo frame.
Quali?
Una fitta rete di "canali", per esempio. Una rete di canali in tutto e per tutto simile a quanto vediamo in questo frame, ripreso - come al solito - da un'altezza di circa 370 Km.
I "Canali di Titano" hanno fatto subito notizia e sia l'ESA, sia la NASA hanno immediatamente parlato di 'chiara analogia' fra Titano e la Terra, così come essa era ai suoi albori.
Questi "Canali", invece, non solo non hanno fatto notizia: essi non sono stati neppure visti!
Ma Voi ci credete a questa "miopìa planetaria"? Noi no. Noi pensiamo che sia più facile far viaggiare l'immaginazione delle persone (tenendole, nel contempo, tranquille...) allorchè si parla di Mondi lontani e, in apparenza, inospitali come Titano.
Quanto più le analogie con la Terra sono lontane ed improbabili, tanto più facile è evitare che vengano poste domande indiscrete...

Fienga - Lunexit Team)145 visiteCaption NASA:"This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a cracked Plain in Western Utopia Planitia. The three circular crack patterns indicate the location of three buried Unnamed Impact Craters. These landforms are located near 41,9° North Lat. and 275,9° West Long. The image covers an area approximately 3 km (about 1,9 mi) across. Sunlight illuminates this scene from the lower left".MareKromium
