APOLLO 15 AS 15-2405.jpgAS 15-2405 - Craters Messier and Messier "A"55 visiteMessier (1) and Messier A (2) are a pair of unusual craters in North-Western Mare Fecunditatis. Messier is elliptical and has bright walls and light rays of ejecta extending at right angles to its long axis (approx. 16,5 Km). Messier A is a doublet crater having two very long rays or filaments of ejecta extending Westward from it. The east part of the doublet has steep, bright walls, whereas the west part is dark and appears mantled. Differences between the two parts are more clearly shown in this oblique view of Messier A (see AS 16-4471). Both craters resemble some small experimental impact craters produced in sand by projectiles following shallow trajectories (4° or less from the horizontal) at velocities of approximately 1,7 Km/s. In separate experiments using single projectiles, both elliptical craters with lateral ejecta lobes and doublet craters have been produced. Thus, it can be inferred that these lunar craters were produced by high velocity projectiles following shallow trajectories. By further analogy with the experiments, the projectiles that formed Messier and Messier A apparently traveled from east to west".

Nota: un caso - davvero spettacolare ed eclatante (nonchè, ad oggi, inspiegato) - di Lunar "Wind-Streaks". Provate a verificare questo (double) streak con l'ampia trama di streaks che circonda una buona metà del Cratere Menelaus.

Sagittarius_M-8_and_M-20.jpgSagittarius Region111 visite"In order for Life to have appeared spontaneously on Earth, there first had to be hundreds of millions of protein molecules wandering in the Universe. The Ninth Configuration.
But given the size of the planet Earth, and the one of the Universe, do you know how long it would have taken for just one of these protein molecules to appear entirely by chance?
Roughly ten to the two hundred and forty-third power billions of years. And I find that far, far more fantastic than simply believing in God".MareKromium
