56-Luna13 - Panorama-02.jpgLunik 13: Oceanus Procellarum (2)133 visiteThe Luna 13 spacecraft was launched toward the Moon from an Earth-orbiting platform and accomplished a soft landing on December 24, 1966, in the Region of "Oceanus Procellarum". The petal encasement of the spacecraft was opened, antennas were erected, and radio transmissions to Earth began 4 minutes after the landing. On December 25 and 26, 1966, the spacecraft television system transmitted panoramas of the nearby lunar landscape at different sun angles. Each panorama required approximately 100 minutes to transmit. The spacecraft was equipped with a mechanical soil-measuring penetrometer, a dynamograph, and a radiation densitometer for obtaining data on the mechanical and physical properties and the cosmic-ray reflectivity of the lunar surface. It is believed that transmissions from the spacecraft ceased before the end of December 1966.

57-Luna13 - Panorama-03.jpgLunik 13: Oceanus Procellarum (3)131 visiteNon comprendiamo bene che cosa si intenda con l'espressione "...it is believed..." che le trasmissioni si interruppero poco prima della fine del Dicembre 1966. Non pensiamo che esista un "si crede" in questo campo, ma prendiamo atto ed andiamo avanti. Quello che ci sembra importante dire e sottolineare, relativamente a questo frame, è che la sua qualità intrinseca è eccellente, la definizione buona ed i suoi contenuti - anche considerato che eravamo del 1966 - davvero strabilianti.
La superficie della Luna appare con grande chiarezza e, già dal tassello n. 2, si intravedono almeno 2 o 3 Star-Like Objects (dunque un elemento ricorrente nella fotografia lunare e NON solo riscontrato in frames "Made in USA"). Come ci danno evidenza le ombre delle antenne del Lander, il Sole è ancora piuttosto basso all'orizzonte; l'area circostante il Lander è alquanto accidentata - più pietrosa, si direbbe, che polverosa - ma non impervia. Intravediamo qualche cratere di modestissime dimensioni e, forse, un "hollow"...

Kaguya-003-20071107.jpgThe Western Side of the Oceanus Procellarum76 visiteCaption JAXA:"This is a still image taken out from the second moving image shooting when the KAGUYA Probe flew from the South to the North, on the Western Side of the "Oceanus Procellarum".
The dark part on the right of the above image is the Ocean and the light area on the left is called the "highland".
The moving image was taken at 05:51 a.m. on Oct. 31st, 2007 (JST) by eight-fold speed intermittent shooting (eight minutes is converged to one minute) from the KAGUYA, and the data was received at the JAXA Usuda Deep Space Center on the same day". MareKromium

Kaguya-005-20071107.jpgThe Western Side of the Oceanus Procellarum84 visiteCaption JAXA:"This is a still image taken out from the end part of the second moving image taking.
We can observe a crater called "Repsold," whose diameter is (about) 107 Km, at the center on the near side of this image. The channel that crosses this crater is called the "Repsold Valley", and its length is about 180 Km (equivalent to the distance between Tokyo and Shizuoka, on the Tokaido Line in Japan). The shooting time was 05:51, on October 31st, 2007.MareKromium

LRO-2501-Oceanus_Procellarum.jpgLunar Landslide in an Unnamed Crater of Oceanus Procellarum59 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

On December 25 and 26, 1966, the spacecraft television system transmitted panoramas of the nearby Lunar Landscape at different Sun angles and each panorama required approx. 100' to transmit. The spacecraft was equipped with a mechanical soil-measuring penetrometer, a dynamograph and a radiation densitometer for obtaining data on the mechanical/physical properties of the Lunar Surface as well as of and the cosmic-ray reflectivity.
Luna 13 transmitted 5 cycloramas over a period of 5/6 days.
It is believed that transmissions from the spacecraft ceased before the end of December 1966.
