PSP_006742_2050.jpgExtremely unusually-looking Surface Features in Mawrth Vallis (Natural Colors; credits: Dr M. Faccin & Lunar Explorer Italia)83 visitePer gli Appassionati di autentiche "Stranezze Marziane", un frame MRO selezionato dal Dr Faccin - e colorizzato in possibili Colori Naturali - ci mostra qualcosa di DAVVERO ESOTICO (se non altro a nostro parere...) nei pressi del probabile Collapse Pit che vedete in alto - nel ctx frame - e supermagnificato a Sx (crop dalla versione JP2000 del frame PSP_006742_2050).
Si potrebbe trattare di "orme" (o di "tracce", se volete restare pragmatici) di qualcosa che si è diretta verso il pozzo da subsidenza sul cui fondo sembra giacere una melma grigio-verdastra dalla texture assolutamente indefinibile - ma che ben potrebbe essere semi-liquida?
Forse.
O forse no.
Comunque, fantasia per fantasia, a noi piace di più osservare questo tipo di features, piuttosto che cercare "città" e "piramidi" ad ogni angolo del Pianeta...MareKromium

PSP_007820_1505_RED_abrowse-05.jpgThis IS SOMETHING! (context frame - credits: Dr M. Faccin)63 visiteGrazie all'occhio del Dr Faccin, un (probabilmente AUTENTICO Mistero Marziano; anzi...forse addirittura due!).
Andate a vedere che cosa si nasconde nella zona indicata dalla croce...MareKromium

Northern_Regions-Utopia_Planitia-Dust_Storm_and_Clouds-PIA15959.jpgDust Storm over Utopia Planitia157 visiteThis close-up image of a Dust Storm on Mars was acquired by the Mars Color Imager instrument onboard NASA's Mars Reconnaissance Orbiter on Nov. 7, 2007, around 15:00 Local Time on Mars. Scientists working with NASA's Curiosity Rover, which is set to land on Mars on Aug. 5 PDT (Aug. 6 EDT), are monitoring Mars each day for similar small Storms that could either drift over the Landing Site or stir up dust that moves as haze over the Site.
This image is centered on Utopia Planitia (53,6° North Latitude and 147,9° East Longitude), along the North Seasonal Polar Cap Edge as it is in late Northern Winter.
When NASA's Curiosity Rover lands on Mars, it will be late Southern Winter. Scientists are looking at similar small storms that form near the South Seasonal Polar Cap Edge. The Dust Storm pictured here was short-lived, lasting less than 24 hours. The image also shows the Seasonal North Polar Cap (at the top of the frame) and gravity-wave Water-Ice Clouds coming off of Mie Crater, just South of the Storm.
Gravity-Wave Clouds, also called "Lee-Wave Clouds", are Clouds that result from changes in Atmospheric Pressure, Temperature and height because of "Vertical Displacement", such as when Wind blows over a Mountain or a (huge) Crater Wall.
The projection of the image is Polar Stereographic and the image has a resolution of about 0,6 miles (1 Km) per pixel. North is indicated with an arrow in this image. The white scale bar is 93 miles (approx. 150 kilometers).MareKromium
