@willoughbykrenzteinburg Год назад
I don't know why this always bugs me so much, but when people talk about going to the moon and saying that the craft needs to leave the Earth's orbit, they are mistaken. At no point on any lunar mission did any craft leave the orbit of Earth. Think about it. The MOON is in Earth orbit. You don't LEAVE Earth orbit to go to the moon; you're just put on a highly elliptical orbit until you make another burn to orbit the moon. You're still orbiting the Earth though. You and your orbit around the moon are collectively in orbit around the Earth. You never leave Earth's orbit.
@willoughbykrenzteinburg
@willoughbykrenzteinburg Год назад
@@colinsouthern This is incorrect. The TLI burn from Earth that sent them to the moon put them on a trajectory known as "free return" - - meaning if they did nothing else, they would circle around the backside of the moon and be slung around and return to Earth. At some point on the way to the moon, once various systems checks were performed, they altered this trajectory that would allow them to be captured by the moon. At no point in time where they ANYWHERE NEAR a trajectory that would escape the Earth's gravitational influence. As for the ISS, the whole "centripetal force" explanation is a gross overcomplication. It doesn't matter how strong the gravitational field you are in is. If you are in free fall, you will be/feel weightless. Many people conflate this with the absence of gravity - which it most definitely is not. The notion that you leave Earth's orbit simply because you are experiencing weightlessness is erroneous logic. You can ride a free-fall type roller coaster right here on the surface of the Earth and experience literally the same state as a spacecraft in space. It's the same weightlessness, and it is not caused by any alterations in the gravitational field, but rather the result of being in free fall WITHIN that gravitational field - - which was the case for the vast majority of the trip to and from the moon. They are simply coasting. A free fall ride here on Earth just lasts a fraction of a second as opposed to the days Apollo astronauts experience en route to and from the moon / and in orbit.

@colinsouthern no. They far surpassed escape velocity. They aren't even orbiting the sun. They have reached escape velocity of the entire solar system. Challenge me all you want. I know what I'm talking about.
@willoughbykrenzteinburg
@willoughbykrenzteinburg Год назад
@@colinsouthern No. STEP ONE : Launch STEP TWO : Get into Earth orbit STEP THREE : Translunar Injection - - AKA, send them to the moon. THIS trajectory was a free return. STEP FOUR : Midcourse (between Earth and moon - AFTER systems checks, etc.) taken off of a free return to a trajectory that would allow them to get into lunar orbit STEP FIVE : Get into lunar orbit. For example - the Apollo 13 explosion occurred during a point in the mission that they had already performed the maneuver that would take them OFF the free-return trajectory and on one that would allow them to perform a lunar insertion burn once arriving. They actually had to perform another burn to put the BACK onto a free-return trajectory and return. I feel like none of this is going to make sense to you.
