A feather falls just like a rock...on Earth:
Apollo 17 lunar ascent module supposedly "blasting off" from the "moon" but there's no flame, exhaust, or even engine exhaust shroud visible

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...

Reaction Control System thruster firing on the space shuttle, Joseph P. Allen's book Entering Space (see stars)
Quote:
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.

Funny thing how this never happened during Apollo:
Save exact fuel as the Apollo Command Module and LEM...
And here's the same fuel during launch at night, just like the Apollo LEM on the "moon":

John, man, your flimsy understanding of photography & physics has convinced me! It WAS all a hoax after all!
In fact, I think we all finally believe you on this matter.
So, you can stop posting this stuff now, okay?
I'm sure everyone, like me, is gonna put on Capricorn One to watch asap.
