Locations of the Orion cameras and details about its new startracker: https://www.nasa.gov/feature/nasa-s-art ... earth-moon

This site says they have lost their signal so no camera views. The mission view works, sort of, on my Linux machine, maybe better using Windows?

I think we will have the same procedure as with Apollo 8. Any camera views will be of a receding Earth and we will not see the Moon until the orbiter arrivies there or is close to it. Once there any images of the Moon will be using the cameras with that 'extended red' capability. Even the Bayer filtered units have sensitivity to the near IR.NASA knows exactly what it is doing.

The field of view of each camera has been optimized to look at the spacecraft, not deep space..

Nothing to see in deep space of course, according to those who have been there.

Yes, no information yet about he camera spectral sensitivity as it's unknown if they have replaced the stock IR/UV cutoff filters by their own. In these cameras the sensor spectral sensitivity is known and goes into IR like with any modern CMOS but as they replaced the stock lenses where the IR cutoff filter is attached to, nothing is known yet.

You are right. That was today confirmed on the press briefing https://www.nasa.gov/press-release/nasa ... moon-flyby . Well, confirmed in the way that high resolution movies won't be taken before the distant lunar orbit insertion burn 6 days after launch on Tuesday. About still images they didn't say much, just that data bandwidth is narrow and mostly used for engineering data currently.

Interesting detail: Both startrackers set 90° apart on the service module rear were dazzled by the attitude thruster plumes and lost orientation temporarily. They expect to see the same effect continuously during the ongoing mission now but also expect it to be reduced with further distance from Earth. Why the Earth distance matters wasn't explained, maybe less frequent firing could be due doe reduced gravity influence.

The optical navigation cameras which are separate from the startrackers are some new system and designed for deep space navigation. If those were also affected wasn't said.

Also: the triple junction solar cells produced 13kW, more than the 11.2kW expected, so 22% efficiency compared to 19%.

GaryN - what would be the motivation for this deception by NASA that you believe in?

An example what's possible today with commercial cameras without a mechanism to track the visual sky movement, photographed from a commercial flight cockpit: https://www.beyondclouds.ch/2017/04/05/ ... g-at-night

technical details: Sony A7s, Canon 35mm f/1.4 lens, ISO6400, 2.5 seconds exposure for each movie frame, f/2.5

The camera reaches 15 stops dynamics which is about the maximum today available as commercial product. For viewing the Moon surface in sunlight and the brightest star at the same time slightly more than 11 stops are needed.

Half way to the Moon and there seems to be lots of light. Where is Earth though? During the Apollo 8 mission the Earth registered 320 lumens from the half way point, so is the illumination just from the Earth?

Nice to see the first highres video now published!
320lm for Earth at that distance would be equivalent to a 15W halogen lamp, good to know as comparison. That temporary bright diffuse light appears to be reflection from the solar cells while they rotate to move the camera pointing direction. The constant bright light causing the shadows should be the Sun or what speaks against that?

The GoPro Hero 4 which recorded the video reaches about 9 stops dynamics so won't be able to show Moon details and stars at the same time. But it should be capable to see stars with the Moon then overexposed if they can switch it to longer exposure times.

For me at least, or anyone else, what is a stop dynamic? /;

It's terminology common for photography and just means how much light the photographic optics can collect to the film or sensor. Decreasing the f-stop number by 1 doubles the amount of light and is usually the clicks you have on the dial to adjust the aperture on the lens. Mathematically: light amount := 2^fstop
That means for 15 the difference in light amount between darkest and brightest object is 2^15 = 32768.
The human vision can capture differences of about 100 million, which is about 2^27 that is why we can see the moon surface and stars clearly at the same time. Best commercial camera I see is currently one with 22 f-stop i.e. 2^22 about 4 million.

Small correction to my previous reply about the f-stop number:

Increasing or decreasing the f-stop number means a step on the following scale printed on the lens:
1.8, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 64

The difference in light amount you get through the lens when switching the setting by 8 f-stops from 1.8 to 22 is the ratio of 2ˆ8 to 1, 256 fold. The same scale is also used for measuring the contrast dynamic capabilities of a digital camera sensor.

About the thread topic, here an interesting new video showing the propulsion stage separation after the trans-lunar trajector injection burn. It shows much more light in the shadow of the solar cell wing than a 15W halogen bulb which is the Earth shine equivalent half way to the Moon, but here the location is still near Earth in low Earth orbit:

I wonder if a previous link I posted a Lucy Earth-Moon image that may add some support to your question.

https://www.nasa.gov/sites/default/file ... h_moon.png

As you had noted to me before the sunlight was from the opposite direction. So it seems the moon is extremely dim with a distance greater than 890000 miles, if it was in a part of its orbit that allowed it to fit in the image frame with the Earth.

So I'm thinking any earth shine element would be greatly diminished. So only the Sun's illumination would dominate.

So if this is reasonable, at the midpoint of Artemis's moon voyage, the opposite might be and the earthlight might be the dominant factor.

I remember in the old Boring Sun thread you once used some analogy that concluded EarthLight would be enough to read a newspaper on the moon's surface.

Modified image to demonstrate the real high contrast conditions between the almost 100% light reflecting spacecraft surface and the 12% reflectance of the Moon, of course only if really visual light is reflected from the surface:
https://twitter.com/areoinfo/status/1594747815762067456

The Moon is adjusted to sRGB intensity values of about 38% which would match 12% light reflectance on the linear scale. https://en.wikipedia.org/wiki/SRGB

My reasoning is that the Sun is not what we are told it is, so what is it? I now believe that the ancient civilisations knew of its spiritual attributes and its intimate connection with our consciousness and the apparent realities we create in the aetheric Matrix.
That no space capable nation has shown us the Sun (or stars) from space using the same type of camera equipment and exposure settings that we use to do so from Earth indicates a collusion at levels of control above those we believe to be running the show. "All the models collapse if the stars can not be seen from space". ALL of them. It was Eric Dollard who set me on this path of investigation, of both the physical and spiritual properties of our Sun, but mainstream science will never accept the spiritual aspects. Some individual scientists certainly do and more certainly would if it could be shown scientifically that the Sun is not what we are told. The experiments are simple, cheap and quick to perform, all that's needed is the unfettered access to space.
The RC church and the others who derived from it do not want us to know what the Sun really is either, even though the RCs were originally Sun worshipers.

So the big question for me is, who is really in running the show?

Thanks for the links Holger. I like your adjusted image on Twitter but wonder how the extended red capabilities of the sensor play into your adjustments. I THINK this is the sensor in question, though it seems the sensor is used by more than one company and may have been modified to suit the needs of the intended usage. A light meter is beyond the NASA budget for the project of course.
