The strongest argument that we actually did land men on the moon is that the Soviet Union did not say anything negative about it. Because of the on-going space race and the Cold War atmosphere of the time, you know they would have put up a tremendous protest about it if they suspected we had faked it.

"Surprisingly, the Moon is a moderately bright gamma-ray source. The only part of the electromagnetic spectrum where the Moon is brighter than the Sun is gamma rays. The surface of the Moon is baldly exposed to cosmic rays and solar flares. When cosmic rays hit the ground, they produce a dangerous spray of secondary particles right at your feet, and trigger little nuclear reactions that release yet more radiation in the form of neutrons. The lunar surface itself is radioactive!"

PN, how can you be such an idiot?

PN: Just look at any of the photos taken from the Shuttle or ISS when it's on the day side — you just see a starless black sky.

Here's the deal: You could adjust the exposure on the camera so that you can see the stars during daytime in orbit, but everything else in the frame that's being hit by sunlight would bloom into a big featureless white blob.

Green and red airglow across the constellation Orion (three Belt stars at center right) photographed by space shuttle astronaut Don Pettit from orbit. Credit: NASA


The green airglow light shows up beautifully from orbit in this time exposure photograph. The blurred lights in the foreground are cities. Credit: NASA



Astronauts get the best view of all of the phenomenon. As they peer out the windows of the International Space Station and space shuttle, the glow reveals itself as a thin green band enveloping the Earth. In a wonderful coincidence of nature, the color of light emitted by excited oxygen is the same as the plants that produce it in the first place: green.

After some failed attempts in the previous days, I managed to capture star trails while the docked ISS and Space Shuttle Endeavour (STS-127) were passing "close" to the celestial pole.

The real reason for no visible flame is that the Moon has NO ATMOSPHERE , and the Lunar surface is extremely bright and reflective due to being naked in the harsh light of the Sun...Many fuels burn with little or no visible flame , but the harsh lighting is sure to dim even 'visible' flames...

For the Apollo lunar ascent and descent module single main engine and sixteen attitude control thrusters, the fuel and oxidizer were, respectively, hydrazine and nitrogen tetroxide. The space shuttle orbiter also uses hydrazine and nitrogen tetroxide in its Orbital Maneuvering Subsystem and Reaction Control System.

In Entering Space, Allen describes the shuttle thrusters: "The forward primary thrusters sound like exploding cannons at thrust onset; and during their firing, jets of flame shoot out from the orbiter's nose. ...The orbiter reacts to the primaries' shove by shaking slightly and moving very noticeably. For the crew on board, a series of attitude changes using primaries resembles a World War I sea battle, with cannons and mortars firing, flashes of flame shooting in all directions, and the ship's shuddering and shaking in reaction to the salvos."

Images from a surface camera pan the lunar ascent module as it lifts off the surface. The background is a pitch black sky. In this image showing the Apollo 17 lunar ascent module "Challenger" supposedly lifting off from the Taurus-Littrow landing site there is no flame, exhaust, or even engine exhaust shroud visible from the bottom of the lunar ascent module.

The lunar ascent module engine had a 15000 N (3500 lb) thrust. The attitude control thrusters for the Apollo C/SM and LM (which had four sets of quadruple thrusters) had 490 N (110 lb) of thrust each. In comparison, the 38 thrusters for shuttle orbit control each have a nominal thrust of 3870 N (880 lb), with a range from 3114 N to 5338 N. Why is the exhaust visible from the 3870 N shuttle thruster but not from the 15000 N lunar ascent module engine?

I have been unable to find any images or video footage of any visible flame or exhaust coming from any of the four quadruple clusters used for attitude control of the lunar module, or from the main engines of the ascent and descent modules. However, official NASA artists' drawings do show a considerable amount of flame and exhaust emanating from the main engine.

In the films To The Edge And Back covering Apollo 13 and Apollo 13, animation shows the LM main engine emitting a bright flame for the various burns between the earth and the moon. In Apollo 13, animation shows visible flame from the LM thrusters during SM separation from the CM and LM.
