They cannot orbit anything. They have to start from Earth/LEO/EPO, stop and restart at target (Moon, Mars, asteroid) and return and stop back on Earth and it is not possible. You cannot carry the fuel (energy) with you to do it and ... you are lost anyway. You don't know where you are in 3D space during the trip/trajectory.

Compare Earth where the light from the Sun must pass through 120 000 m of atmosphere full of atoms of all kind before hitting ground and sometimes with clouds in between. It is a big difference, i.e. the light conditions differ. IMO the Apollo 11 pictures were taken in atmosphere ... on Earth. But the photos show a gray surface. Gray surface of the Moon? Isn't it black? Or white? Or yellow? And Buzz used fill cards to light up the shady areas with Moon light 1969. As far as I am concerned Buzz is an alcoholic that sees everything a bit hazy.Which I explain at my popular website.However, the main reason that Apollo 11 never visited the Moon is the fuel! It didn't have enough fuel to do the trip. Another reason is the re-entry and landing in Earth. It is impossible! satellites never return safety. They always burn up!

quote: Op zondag 12 maart 2017 12:04 schreef Heiwa het volgende:[..]The speed after trans-Earth injection was maybe 2 640 m/s. But in what directions? Everything is unclear. The Moon was at this time still orbiting around the Earth at 1 023 m/s speed, so one way or another the CSM had to reduce that tangential speed in Moon orbit to 0. It would appear they got away from behind or aft side the Moon into the radial course towards Earth, while the Moon continued its circular, orbital course around Earth.Who knows? Evidently the CSM had to reduce the orbital/circular speed orbiting Earth at Moon altitude to 0 and just get a radial speed away from Moon towards location X in space and location B in orbit around Earth.
quote:It is quite complicated to navigate in space, when the islands or moons are moving all the time, and frankly speaking I do not understand how it is done in detail. Only 3D velocity records using Sun (fixed) as base and none are available.I sail ships, and always know my location with radar, triangulation and sextant. Also, ships sail on a 2D water surface, space craft is in 3D space! How the Apollo space craft knew its location in 3D space is unknown!
quote:The distance travelled during the 150 seconds trans-Earth injection - you have to get out of orbit around the Moon at exactly the right moment and location A and into a radial trajectory towards location X and then Earth overcoming Moon gravity force - was only 292 500 meter (assuming Moon didn't move but during 150 seconds the Moon evidently displaced 153 450 meters).You probably were at same altitude 115 000 m during the maneuver, but who knows and cares? During this time the Moon and Apollo 11 moved 365 722 meter sideways which you had to consider one way or another. If you had directed your rocket engine in the wrong direction, you would not have been in orbit around the Moon but going astray or crashed. Note that Apollo 11 has no fuel reserves or redundancy. One error and you are finished!
quote:The conversation of the asstroholes during the 6 minutes lunar orbit insertion, LOI, burn between 75 hrs 50 minutes and 75 hrs 56 minutes of the flight does not reveal anything dramatic ... except that they can see the Moon while braking backwards with the LM at the end of the spacecraft. How was it possible? Were the three (crazy?) assholes aboard piloting the spacecraft manually with compass/chart pushing the brake button or pedal in the process looking out through the window like on an airplane? How did they know what was up/down/right/left and the directions of velocity and the force.
