APOLLO 14 AS 14 66-9338 HR.jpgAS 14-66-9338 - Flag and tracks (HR)94 visiteEd Mitchell took this splendid picture after he and Shepard jettisoned the PLSSs in preparation for launch. Of particular interest are the tracks made by the crew and the MET during the traverse to the ALSEP deployment site and during the return to the LM. The ALSEP Central Station is about 180mt from the LM. Note the excursions the crew made around the rimless crater in the foreground and the large depression in the middle distance that they traversed in both directions. Without the visual clues provided by the tracks, the depression is not easy to pick out in this down-Sun photo. Note that the flag is now pointing on an azimuth of about 335 and undoubtedly moved from it prior pointing of about 120 as a result of the cabin depressurization done for the jettison. Journal Contributor Jim Scotti notes that we "can see the impact 'crater' and roll marks made by the PLSS farthest from the LM. It rolled on it's side and you can see a fair bit of detail in the hoses and straps on the righthand side of it".

Luna17-Horz02.jpgTracks on the Moon279 visiteAs with many Soviet space images, generation loss prevents us from seeing the original quality. Most Lunokhod images are derived from scanning printed images or second-generation film copies.
Each stage of photography, printing and scanning introduces noise, nonlinear brighness mapping, and (worst of all) clamping to white or black.
As a matter of fact, all these images only hint at the appearance of the original video signal.
Nota: oltre le tecnicalità sulla fotografia, guardate attentamente il "nido" e le "tracce" lasciate dal Rover Lunokhod-1. Eravamo nel 1970, in piena Era Apollo, lontanissimi dai giorni di Spirit ed Opportunity eppure...eppure la tecnologia di Spirit ed Opportunity c'era già: davanti a noi, in queste immagini, e sulla Luna.
Le considerazioni - inevitabili - che seguono, già le conoscete...

Luna17-Horz03-b.jpgThe "Tracks" - again - of Lunokhod-1179 visiteLuna 17 was launched from an Earth parking orbit towards the Moon and entered lunar orbit on November 15, 1970. The spacecraft soft landed on the Moon in the Sea of Rains. The spacecraft had dual ramps by which the payload, Lunokhod-1, descended to the Lunar Surface. Lunokhod-1 was a lunar vehicle formed of a tub-like compartment with a large convex lid on eight independently powered wheels. Lunokhod-1 was equipped with a cone-shaped antenna, a highly directional helical antenna, 4 tv cameras and special extendable device to impact the lunar soil for soil density and mechanical property tests. An X-Ray spectrometer, an X-Ray telescope, cosmic-ray detectors and a laser device were also included. The vehicle was powered by a solar cell array mounted on the underside of the lid. Lunokhod-1 was intended to operate through 3 Lunar Days but actually operated for 11! The operations of Lunokhod-1 officially ceased on October, 4, 1971, the anniversary of Sputnik 1. Lunokhod1- traveled 10,54 Km and transmitted more than 20,000 TV pictures and more than 200 TV panoramas. It had also conducted more than 500 lunar soil tests.

Luna17-Horz09-b.jpgLarge depression and Rover tracks167 visiteUn'immagine molto importante poichè ci mostra, in maniera più che discreta, sullo sfondo verso la Vostra Dx, le tracce lasciate dal Rover Lunokhod-1.
Esse, oltre a dimostrare che il Rover si mosse in lungo ed in largo sulla superficie di questa zona del Mare Imbrium, ci dicono pure che questo antenato di Spirit ed Opportunity riuscì, diremmo senza difficoltà, ad attraversare una sensibile depressione del terreno: una prova ulteriore dell'elevata qualità del Rover, dei suoi sistemi di guida remota e delle sue notevolissime capacità di movimento.
Se Vi chiedeste come facciamo a dire che Lunokhod-1 non ebbe problemi ad attraversare la depressione lunare che si vede in questo frame, Vi diciamo che lo abbiamo dedotto dalla linearità delle tracce da esso lasciate sul terreno. Tracce che ci suggeriscono una guida spedita e per nulla indecisa. Le zone più "smosse" della Superficie Lunare, invece, ci indicano, i punti di stazionamento, di (eventuale) slittamento e di sosta per l'esecuzione di esperimenti del Rover.

Luna17-Horz27.jpgLunokhod-1 rolls inside a small crater (1)117 visiteLe tracce lasciate dal Rover Sovietico Lunokhod-1 sono chiare: il piccolo robot è riuscito non solo a giungere sul bordo del piccolo cratere senza nome che abbiamo visto nel frame precedente, ma ci è anche entrato dentro, senza particolari problemi.
Il Lunokhod-1 è entrato ed è uscito dal cratere e, probabilmente, è anche riuscito a prelevare campioni ed a fare esperimenti: non c'è male per una tecnologia bistrattata come quella della fu-Unione Sovietica.
Una tecnologia, per giunta, vecchia di 36 anni...
