Fake of Fake Moon Part-4

If the sun is the only source of light on the moon, why do lots of the photos, like this one, show shadows at different angles and lengths? Doesn't this show the use of spot lights?







You can see in this photograph that the astronaut on the right is much longer and at a different angle to the one on the left. This isn't at all strange if you consider the slopes on the landscape. There is a dip in the surface between the two figures. The shadow on the right is sloping downhill, the shadow on the left uphill.

These diagrams represent what is happening in the photograph.
The angle of the sun is identical in both diagrams, yet because of the angle of the ground the shadow on the right is almost double the length of the one on the left.






You might also want to ask; if they was more than one light source because spotlights were used, then why do we not see more than one shadow on everything? Surely this would be impossible to avoid, yet no photograph ever shows it happening

Fake of Fake moon Part 3


Why can we see the astronaut in this picture when he is in the shadow of the lander? Shouldn't he be in the dark?




This is a question posed about a lot of the photos taken on the moon. What needs to be realised is that the sun, while being the only source of direct light, was not the only light source. Light reflects off everything around the astronauts and because this is very bright light, the reflected light can be very significant.
So the answer to all these questions is reflected light. In the photograph above the astronaut is significantly above the ground and is lit by reflected light off the surrounding lunar landscape. The fact he is wearing a pristine white spacesuit also helps, as it reflects most of that light again. So he really shows up against the shadow on the ground below him.
The highly reflective white spacesuits also explain some of the light in individual pictures of the astronauts. These were taken with the sun's light reflecting off the photographer, providing a great deal of infill on the astronaut being photographed. Remember that the photographer would be reflecting a lot of light, think of a snowy landscape on a bright winter's day. This is a very common trick also used by photographers on Earth. They get someone to hold up a large sheet of white card or cloth. This reflects the sunlight back across the shadows on the person being photographed, providing a natural infill to any harsh shadows.

Fake of Fake Moon- Part 2


This photograph of Buzz Aldrin was taken by Armstrong on the moon's surface. The camera he was carrying was mounted on his chest pack. So why does the picture appear to have been taken from above Aldrin and we can see the top of his head?





The answer to this question is quite straight-forward. The ground they are standing on is not flat. Armstrong was further up an incline, so he was higher than Aldrin.

Fake of Fake Moon- Part 1



Why does the dust clump together like wet sand? Everybody's seen the pictures of the astronauts' footprints, but should the dust have left any trace of the footprints? Wouldn't they have disappeared like footprints in dry sand dunes?














The lunar dust is not anything like sand. The particles are smaller and much more irregular. Sand on Earth is the result of weathering and has been rounded and smoothed by wind, water and oxidation, but dust on the moon are minuscule shards of broken rock from asteroid collisions. Consequently their surface at a molecular level is a jagged mass that won't get smoothed off and don't have any weathering to smooth them off. This means that when compressed, say by a boot, the dust particles will grip with each other very readily, using and retain the shape. All without any water.

A "Star" gone forever....

Posted by Picasa
"Grand Father of kannada science literature is no more"
"He inhaled Science and Exhaled Science"
"He died with the pen in his hands & science in his heart..."
I was really shocked when I heard that G.T.N(G.T.Narayanarao) is no more.
Oh Dear!
How can I believe that the person because of whom I am introduced to the beauty and glory of this cosmos is no more!!
I am unable to digest this fact!!
I met him two years ago in Mysore University, where I participated in a state level popular science writers workshop...
I still remember what he said to me personally..
"Mr Hariprasad, If you want to explore the beauty of cosmos more deeply than what you are experiencing till now you must look in to the universe through the eyes of mathematics...."
We could hardly find a kannada science writer who never read G.T.N Books.
What was so special about his books?
1. His exceptional Command Over the subject and language...
2. The uninturrupted rythm of science....
He was recipient of various awards, including Kannada Rajyotsava Award-2007, Karnataka Sahitya Parishat and Kannada Vijnana Parishat Award. He authored 60 books in Kannada and English, covering science, travelogues, translations of technical publications, astronomy, biographies of famous scientists. Many of his books were text books at University level.
His books were masterpieces...
They opened the beauty & glory of this universe to karnataka people...
Really a "Star" is dissappeared physically forever here on the earth..
But still we could experience his greatness through his books...
In that sense..
He is immortal in the hearts of every science lover..
