The Nvidia graphics card and the theory of the conspiracy of the Moon landing

Neil Armstrong and Buzz Aldrin arrived on the Moon in 1969, fulfilling the goal that had been proposed to the government of Kennedy in his time, which was that of putting a man on the Moon before I got the year 1970. There is a photo of the thousands that were taken, that is iconic, that is the following:

The photo, taken 45 years ago, shows Aldrin descending from the lunar module, where it gives you all the shade. It is a great photo and according to the conspiracy, too good to be real. The argument is this: “because the Sun is behind the lunar module, and Aldrin is in its shadow, the details of the astronaut would be less obvious precisely because there would be less light. This suggests that there is another auxiliary light source”, and the conspiracy added: “this is certainly one source of auxiliary light. Maybe in a studio, maybe in some part of The Angels.”

The doubt is reasonable, we must recognize it. But the people from Nvidia has a secret weapon: “Maxwell”, a microarchitecture which is based on your graphics card, which you can manage via the appropriate software, the most important challenges of visual computing. Maxwell is probably one of the microarchitectures most powerful in the market of computer graphics today.

Thanks to Maxwell, a team in Nvidia reconstructed the scene of the arrival to the Moon using Unreal Engine 4, a game engine developed by Epic Games. Simulated how came the rays of the Sun coming from behind the lunar module, as well as the suit of Neil Armstrong and Aldrin down out of the ship.

Mark Daly, who led this team of developers, said with satisfaction: “The men have lost part of their lives in the Apollo program, so it bothers me when people say that everything was fake”. The veteran of Nvidia, added: “people risked their lives to reach the Moon”.

To understand the work and the discovery of the team of Nvidia, they worked with one of the key elements of the system, the technology “Voxel-Based Global Illumination” (VXGI), which best represents how the light bounces off the objects even in real-time.

To do this, VGXI divides the geometry of the scene in many thousands of tiny boxes called “voxeles”, or pixels in 3D. Each of the six faces of each box is analysed to determine its opacity (i.e., how transparent it is), as well as the shape to emit the light (how much, what color, and even the light that is reflected from other objects in the scene).

The team then reconstructed the scene of Apollo 11 on the site of the lunar landing. All these boxes helped to capture the way the light bouncing off of an object to another. So, if an item is moved to the front of the light source, the illumination of the scene surely would change dramatically. This represents a major step forward in terms of graphics. There is No to add probably that all of this graphical environment dynamic is computationally very intense.

Maxwell accelerates the creation of voxeles (a process that is called “voxelatización”), with the support of the hardware by using a technology called “multi-projection”. The latter allows the GPU Maxwell render once for each face of each voxel.

So then, to recreate the Moon landing, the computer Nvidia collected as many details as he could. Investigated the lunar topography, the properties of the dust in the surface of our natural satellite, and measured the reflectivity of the material used in space suits. It was during this research that the programmers found a big clue: in a video in where you see Aldrin descending the lunar module, there was a bright pinto of light that moved each time you moved the camera.

The team then used Maxwell to simulate the conditions of the moon’s surface during the arrival of the module to the surface 45 years ago, revealing how Aldrin was illuminated by light reflected from the surface of the Moon and the space suit Armstrong. When they observed the brightness moving, Daly said: “my god, my God, what we have”…

How was it an artificial light or as suggested by an architect from Nvidia, the reflection of the brightness of the suit of Armstrong? In the first instance, Daly commented that this last idea about the suit of Armstrong’s illuminating Aldrin not seemed to be anything compelling. Daly said: “Imagine yourself. how much of a space suit can contribute to the light in the scene?”.

What’s remarkable is that the hardware, the Nvidia card, indicated that the intuition of Daly was erroneous, and the suit Armstrong was giving more light than expected. In fact, the team was able to reproduce how the light illuminated Aldrin at the exact moment in which the photo was taken. This did reflect to Daly in the sense that they had discovered evidence of having reached the Moon.

But this was not the only thing that they found to show that the conspiracy theories were wrong. For example, the photos from the site landed on the moon do not show stars in the background. And this was another argument of the conspiracy. How is it that you cannot see the stars in the background of the lunar landscape?

Maxwell found that the reason that the stars are not visible is that the cameras were placed to capture the scene inside the lunar surface. But are these stars. “our team was able to be able to distinguish between them by digitally changing the exposure of the photos and, therefore, will reveal the stars in the background. Thus, another argument of the conspiracy eliminated.

Show that you arrived on the Moon really has a host of other tests. NASA has photographed from their orbiters around the Moon, images of the remains of the missions that they came to stepping on the satellite of the Earth. But perhaps none of this will convince the conspiracy. This time is similar to the Holy Shroud, which is already being demonstrated, not covered the body of Christ because it is dated in the year 1400. But no matter what they say, the science, the particular fabric is saved with all suspicion by the Vatican, although in historical terms about the image of Christ covered after the crucifixion, is absolutely false.
