был бы очень благодарен за предоставленое на "пощупать любым органом чувств" "честное слово американцев о побывании на Луне" в любом употребимом виде, скане газеты типа нашего "ТАСС уполномочен заявить" с адекватными подписями, теле или радиопередачи с прямой речью о побывании американцев на Луне лица- облеченного властью и доверием.
Surveyor 3 and a sister ship Surveyor 7 actually dug into the Moon and measured how hard their drive motors had to work to scoop, press, and scrape the soil. To interpret those measurements more than 40 years later, however, Wilkinson's team needs to know the dimensions of the Surveyor scoops. Unfortunately, they learned, the blueprints had been lost! Only a scoop itself could provide the answer.
That sent Wilkinson to Hutchinson, Kansas, in April 2007 to borrow the Surveyor 3 scoop from the Kansas State Cosmosphere in order to make detailed measurements.
Measuring the scoop, however, would prove to be no simple matter. You can't just lay a ruler along the scoop and read off the dimensions. Indeed, you can't touch it at all. The Surveyor 3 scoop is in an airtight triangular container, and NASA curators do not wish the scoop to be removed because handling in air will degrade the historical fidelity of the unique artifact.
So the Glenn team borrowed photogrammetry apparatus from the Kennedy Space Center. Photogrammetry is a technique of measuring objects strictly from photographs. They have a photographic studio setup with a white background. GRC team member Juan Agui, an expert in digging force experiments, photographed the scoop in its container next to a standard photogrammetry cube, which has a precise checkerboard pattern on it. Then, using software, Robert Mueller of the Kennedy Space Center extracted dimensions using mathematical triangulation, measuring from points on the scoop to points where corners of dark checks meet on the cube. The software was developed for the Columbia Accident Investigation Board activity.
"Photogrammetry is pretty good," Agui remarks. "We got measurements of the scoop accurate to 0.030 or 0.040 inch (~1 mm)."
