Item 11 - Transmission quality





The video is very good, as one would expect from the technology that comes out of the Far East, however only the audio recorded on the surface appears to be pretty good quality. Astronaut comms aren't that good, but they have a very good background noise supression system. A rather labored point, perhaps trying to demonstrate the clarity was because it was on Earth, when they could simply have added some video distortion to the picture, had they deemed it necessary. Bunkum.


Item 12 - Pre launch document released early

Somebody put out the press release early. The actual dialogue quoted appears to be fairly standard, and obviously something rehearsed in their genuine underwater facilites. Embarrassing for China, but hardly a unique event to have a pre-prepared press release in news reporting of big events.


Item 13 - China faked the Chang'e photographs




It was actually just one picture that sent tongues wagging. Completely wrong, the Chinese picture is taken at a different angle, and actually has a newly formed crater on its picture that can easily be verified. If this find had any credence, it would have had all the mad conspiracy theorists scrambling for more evidence. None was found, just this one picture. A leap of faith logical fallacy argument based on a single photograph.

Here is the picture against the NASA one:-



































Item 14 - The arc of the Earth

He compares the relative Earth arcs of the Shenzhou spacewalk with other footage, and says Earth's arc is different!

The Chinese spacewalk is closer footage than the example given and has a wider angled lens.


Item 15 - The clouds are speeding up





This is more bunkum to explain both the motion of the flag and the space debris. He uses a short passage where the cloud cover appears to brighten up very quickly. This is light striking the solid cloud and diffusing it. The camera is set for near field operation so sees it over exposed. The craft as stated is orbiting at 17,000mph.


Item 16 - The floating cables

He says the astronauts air is provided in the tether cables!! He then says the astronaut is holding it down to stop it floating up!

The tethers have shape memory caused by them being wound on drums during manufacture. The only tendency the cable has in an unrestricted vacuum is to assume that curled position from being wound around a large drum. There are numerous examples where it makes this same movement in a horizontal vector in relation to the camera. Bunkum.


Item 17 - The "missing" outer atmosphere halo

He talks about the blue halo missing from the footage showing the outer part of the Earth's atmosphere that scatters blue light.

The halo is visible under most, but not all conditions, as shown by the examples below. The camera for Shenzhou 7 was set to expose for sharp nearfield and in digital quality, the Earth in the background is consequently over exposed and a little out of focus.























Watch 10 seconds of this video from the time marker 13:21. The first view has no halo, the second has a huge halo:-

Item 18 - The Earth moves

Says the earth moves up and down a tiny bit, and questions how does that happen in space.
The craft follows an elliptical orbit, it has very small corrections made at intervals to its forward orb-rate rotation. Perhaps he should have asked this basic question before adding it into his video?


Item 19 - The change in degrees towards the Sun

He talks of a 120 degree sun angle change in the 15 minutes we see the craft!!

A standard 90 minute orbit makes a 60 degree orbital change in 15 minutes not 120 degrees. However, the craft is following a 42 degree orbit so that equates to nearer 40 degrees. Just really bad math and ignorance of the orbital path.


Item 20 - The supposedly lit piece of the craft

He says the Sun angle never changes on both cameras, then indicates that it lights up part of the craft and then back off again. He says it is impossible, especially at 90 minutes per orbit.

If we assume that the area he highlights as being lit is done so by the Sun, when the light recedes, one would expect the top part to be still illuminated last of all. But it isn't as this screenshot indicates:-





























The screenshots show the light is coming from the opposite direction, the Earth, as the bottom part is lit last of all! Simple attitude control would account for this, as previously explained. In addition, 10 minutes later on during the space walk, we see the Sun angle has changed accordingly, representing what we would expect to see:-





















Item 21 - The extra astronaut

He says there are 4 distinct voices and only 3 astronauts.

This is just speculation. He begs the question, then plays some different clips, all labelled up for the viewer. Basically he is just clutching at straws. The voices are all varied volume inflection and clarity. To me, voice 2 is the same as voice 4, just closer to the mike(ie. face not turned to the side maybe), or speaking softer on some of the clips he plays.


So this is your idea of a credibility test is it!?

Only those with the same ignorance and gullibility as yourself, ie. no reasoning ability, nor any motivation at all to verify that what is said is actually complete Bullshit........actually pass the test.

Meh!!!

Here is part of the Chinese Spacewalk Footage:-

http://www.youtube.com/watch?gl=ES&hl=es&v=gMxQEHfU6hM

Before I begin debunking this, the user who made this, freely admits he has been given a "good run for his money" and concedes in this video that many of his points have been debunked.

http://www.youtube.com/watch?v=U54siu8cEe0

I will pay particular attention to those that he insists have not.

Underwater Footage

During underwater footage in weightless training, the surface will reflect the light and cause shimmering lights on all surfaces.
A good example of this is the cylindrical object in this video, shimmering as light is refracted all around it:-

http://www.youtube.com/watch?feature=player_detailpage&v=tTU8U7y0CUI#t=25s

There is no evidence of this in the entire Chinese spacewalk. They would have had to have used a sealed chamber painted black to avoid all light reflection and surface wave refraction.


Item 1 - The "Bubbles"







These are not bubbles. It is a combination of small loose assorted items, pieces of paper and frozen condensation. Many times in space, the introduction of a vacuum causes parts of the various coatings on the interior to freeze and break away.
Here is a video showing them exiting the hatch and always at different angles:-

http://www.youtube.com/watch?v=kG4Z_r38ZDE

The statement about there being zero gravity is just plain wrong. Zero-g means zero g-forces not zero gravity. This whole idea about accelerating objects is so easy to explain. The gravitational force at that altitude is circa 9 metres per second squared. Any object expelled towards the Earth, will still have orbital velocity, but as it now has slight downward velocity, it will accelerate very slightly as a result.The object that has caused most of a flap amongst hoax claimants, is merely a piece of debris that has moved diagonally towards the camera, in itself adding to what looks like even more acceleration. We can deduce this quite easily from it's apparent change in size which does not comport with a small depth change for a so called bubble.
The idea that objects should not exit the hatch after 10 minutes is invalid. He implies that it is due only to the very slight pressure release(usually residual air pressure) that the objects are expelled in the first place, when it is also that in moving about inside the craft, they have impacted the inside and deflected through the hatch. As seen in the video above, even the paper accelerates - wet sodden paper does not float!
It must also be pointed out that due to the way a wide angled lens shows movement at its edge, it naturally appears to move slightly quicker.

Adding this video to show the "bubble" that is a flat piece of tape:-



And this one to isolate the salient clip:-




Item 2 - Wave Blowers





Complete hogwash! Neutral buoyancy is established using weights.

http://en.wikipedia.org/wiki/Neutral_Buoyancy_Laboratory

"The principle of neutral buoyancy is used to simulate the weightless environment of space. First the suited astronauts or equipment is lowered into the pool using an overhead crane. Once this is done the suited astronauts weighted in the water by support divers so that they experience no buoyant force and no rotational moment about their center of mass."

http://en.wikipedia.org/wiki/Neutral_buoyancy

"Neutral buoyancy is a condition in which a physical body's mass equals the mass it displaces in a surrounding medium. This offsets the force of gravity that would otherwise cause the object to sink. An object that has neutral buoyancy will neither sink nor rise."

This video demonstrates that very principle:-

http://www.youtube.com/watch?v=cZDSFi5y_nk

This video shows tether cables with no tendency to rise and also demonstrates always in every example, the bubbles rise vertically:-

http://www.youtube.com/watch?v=tvQEbP1s4pc

Further, a waveblower would set up a continuous current and would not magically disappear once it hits an object. if there were 2, one either side as suggested, there would now be cross currents. These in turn would cause significant instability of anything caught in its wake. There are no signs of turbulence you would expect from water movement, or no additional light refraction.

Wave blowers are introduced by the film maker to explain why the "bubbles" don't rise vertically, a logical fallacy and bunkum.


Item 3 - The Mission Commander "slip-up" 






Is the film maker saying there is no water inside the hatch then?! The communication is actually pretty garbled. The Mandarin word for water is pronounced "shuway" I can't hear that said.
But some comments on the video disagree with the film maker:-

















Item 4 - Odd row of lights 





They are located here:-
























Here is a short excerpt referring to them:-

http://news.xinhuanet.com/english/2008-09/28/content_10130548.htm

"Zhang Tao, a technician with the Shanghai Institute of Technical Physics under the Chinese Academy of Sciences, said the Shenzhou-7 mission's success marks China's space program has "entered a new stage." Zhang was in charge of developing the illumination lamp on the exterior of the Shenzhou-7 vessel."


Item 5 - The Markings on the Craft at take-off

He compares Shenzhou 1 launch with wider thruster displacement to Shenzhou 7. Shenzhou 1 has a noticeably more split triple exhaust, Shenzhou 7 is more combined - it has a bigger payload and more thrust. There is also a much bigger surface smoke cloud on the Shenzhou 1 launch. Here they are side by side with completely different plumes evident:-




















He says the photograph used by China Weekly shows different markings. It's just a low resolution version of the original. The markings are the same!




















Item 6 - What is lighting the craft?





Of course it's Earthlight! The Earth has an albedo of 35%, meaning it reflects that percentage of light cast upon it. We can clearly see it is daylight.


Item 7 - The flag moves like it does in water!






This is complete nonsense. A flat fabric will not move that way in a viscous medium. The drag co-efficient of water would simply not allow it to rotate unrestricted. The fabric would simply wrap around the small pole. The references to there being no noticeable movement of the astronauts hand, ignore any movement made by simply moving the finger and thumb. He indicates that the flag is moved by water movement which is simply bunkum, water doesn't rotate a flag like that, it is simply impossible. The movement was supposedly down to the mysterious wave blowers!


Item 8 - Astronauts always keep hold of the rails






Whenever astronauts let go in other space walks, they are either tethered, or have attitude control thrusters on their suits. Inexperienced astronauts could be forgiven for taking care. The narrator suggests they don't let go, because the water will sweep them upwards, yet it has no such effect on their position. If there was a mystery wave blower current, their legs would be swept upwards!


Item 9 - Supposedly static Earth position





For hours he says? How about 20 minutes maximum, as is the duration of this spacewalk.
The craft thrusters initiate a rotation about its horizontal axis that matches its orb-rate around the Earth. It is used on most satellites, as opposed to something like the Hubble which has a stellar inertial orbit.
Explained here:-

Item 10 - The fast moving clouds




I slapped my forehead at this statement! The clouds aren't moving!! The craft is orbiting at circa 17,000 mph on a 42 degree inclined orbit.
