Lunar Rover

[Industrial Toys]

Didn't know whether to put this in this heading or Rural. Is the moon considered Rural?

Does anybody know how the Lunar Rover was stored on the LEM?

I googled some pictures, but it doesn't make any sense. The only picture I found looks like one of those cases when you try and load something that is way too big. Half of it is sticking out and you come to the conclusion, it aint gonna fit!

My Post 4001! Obviously some kind of space odd-yssey.

Pretty sure the dealer delivered it to them so it was waiting for them when they got there. I think somebody mentioned something about how good Subaru is, Rover is even better!!!

COOL! Thanks for that.

I see some wrapped up chain. What are these guys, farmers? They look more like cooks. And they appear quite unimpressed with their engineering. Comments on the one video are quite interesting.

Anyone read 'Artemis' by Andy Weir ? he also wrote 'The Martian'

Lots of "rover" activity as the story is set in the near future with a virtual city on the moon...it's not near as intriguing or profound (slightly hamish) as The Martian but the tech, history and science is there as well as the humor...

I bet the POD charges were killer.....................

Knowing NASA, they probably paid double just to use up their budget so they can ask for more next year!!

Here's one from the moon.

Here's one from the moon.

If interested check out (Moon machines) a good tech series with LOTS of Vintage footage

Each show deals with individual machines that made Going to the moon possible.

Just a few seconds after the vid you posted ends...
Dave Scott got a big surprise when the front steering didn't work- luckily it was designed with 4 wheel steering so they just drove it like a fork lift. 34:00 minutes is where they start unloading it.

What does a rocket push against in the vaccume of space?

I saw a great video of some excursion in their buggy, maybe 5 KM to some crater. There was a lot of video of the two of them, in proper focus, properly framed and zoomed. I am curious how they managed that. It (the camera) would have had to be remote controlled, but from where and how with such real time precision? A camera man standing there holding the camera could not have done a better job.

For every action, there is an equal and opposite reaction. The burning fuel goes one way, the rocket goes the other. It doesn't need any air to push against.

I'm having a hard time understanding that. If I push my hand out quickly into the air, I don't go anywhere. Push it against a wall and different story. Same with a jet ski. Feed it some water when the jet isn't submerged and it won't have (much) forward movement.

basically, rockets are only needed to get to space (through the atmospheres)...once in space (vacuum w/no gravity) for simple movement all that is required is a boost...once boosted an object will move basically forever in whatever direction the object was shoved etc...to stop or slow down would require a calculated boost or shove in the opposite direction...

Basically if you could live in a vacuum with no gravity a fart would propel you...

When you push your hand into the air you didn't eject any mass and the air moved around your hand. Some small actual thrust was generated by your hand pushing mechanically against the air molecules.. When you pushed into the immovable object, you still didn't eject any mass you used your muscles contractacting to mechanically move your self. The examples you gave have nothing to do with mass ejection as a method of propulsion in space. Nothing. You are trying to draw and inference and there is none. To move yourself in space you must eject something out the "back". That mass could even be a small ion stream. That would be enough. Until you get the warp drive working.

You say "I didn't go anywhere" I say you did. It is just so small you didn't notice it.

What a rocket exhaust pushes against is the rocket. Same as a blown up and released balloon.

And there is gravity in space. It just isn't felt when in orbit. If a satellite stopped moving in its orbit, it would fall.

True for LEO (Low Earth Orbiters) but not true for satellites out past the La Grange points. These satellites are influenced by the weak gravity from the Sun and Moon. In deep space there are no gravitational forces.

Technically that's correct but there are places in space that are very far from objects that create gravity so the effect is minimal...may not be total
"zero gravity" but it can come close... FWIW the moon's gravity is 1/6th of the Earths's

So if the exhaust pushes against the rocket, doesn't there have to be the other half of that equasion, the thrust pushing against atmosphere?


If you had a room with a vaccume and released an air filled balloon or lest say a co2 cartridge with a hole poked in the end, would it propel itself?

For sure...did you happen to see the movie 'The Martian'?
