For Earth orbit you need much faster flight than you would need to
stay in orbit around the moon, but nevertheless it is quite fast. On
Earth it took a Saturn V rocket, to lift the craft into orbit. On
the
Moon it would take less fuel, but way more, than the few gallons,
they
had in the lander.

Ok, let's see your math.

I mean if you know they needed more, then clearly you have calculated
all this out and know exactly how much they would need and whether
they
could have that much on the lander.

So let's see your work.

---- Insert mathematical proof here.

Here I will even aid you with the specifications for the mass,
amount of
fuel, type of fuel, specific impulse, thrust provided, available
delta-V, and so on.

Well, I'm a little too lazy, but a rough calculation is possible:

There is the Tsiolkovsky rocket equation
velocity_final=v_exhaust* ln(mass_start/mass_finish)

V_end= 2200 m/s * ln (4547 kg/(4547-2353) kg)

that is :
v_end approx. 1603 m/s

this is an estimated calculation without gravity.

the final velocity is reduced by
delta v = g_moon * (time of engine running)

Don't know that number (time_ engine)

Maybe 100 seconds (???)

makes:
delta v = 1.6 m/s²*100 s=160 m/s

What gives a rough estimate for the final velocity of the landers
ascending stage of
v_end = 1440 m/s.

Now the orbital velocity had to be compared. But I don't have the data
and actually I'm too lazy to find them out. But usual orbits should be
a little less than escape velocity, what is
v_orbit_escape = 2380 m/s.

V_end is a rough estimate ('thumb times pi'). For better calculations
someone with more experience in rocket science is needed.

I cannot even tell you, if the ascent stage is fast enough or not. But
my intuition tells me, it is not.


IOW, you don't know what the hell you're talking about, and you're too
lazy to do the work needed to find out if what you think actually has
merit or is simply bat **** crazy.


I haven't claimed to be a rocket scientist. I'm totally happy with an
rough estimate. I could do it better, for sure, but do not want.

What you have isn't even a rought estimate that applies. You simply
threw some stuff up there, came up with some answers, but didn't use the
data from the apollo program, which it should be noted I was even nice
enough to lead you to by the hand, much less show that the results
produced proved that a landing and take-off physically could not occur
given those conditions. You simply flopped around trying to put together
an argument.

Free hint: If you're going to say someone else is lying, then you need
to make sure you have your ducks in a row and can PROVE IT.

All you've shown is that you are an empty headed conspiracy theorist,
with lots of notions, but no facts, no proof, and from all evidence
absolutely NO desire to find out what the facts really are.

You are absolutely wrong!

Then let's see your proof. Not some bull**** hack job you threw together,
but conclusive factual objective mathematical PROOF.....

Otherwise, I'm right.


The rocket equation is a method to calculate the final velocity of a
single staged rocket.

The ascent stage would fit to 'rocket', even if doesn't look like. It
had - of course - only one stage.

The rocket equation ignores gravity. The moon has low gravity, what makes
this equation even more usable.

The precise orbit of the orbiter I could figure out, but that would be
'work', while typing stuff into the UseNet qualifies as 'leisure'.

See what I mean.....no desire to find/figure out the actual facts.

So I decided, I don't want to do that.

IOW, screw figuring out the facts.

This decision is absolutely my right

Absolutely, you have every right to be as stupid and ignorant as you
chose....but don't confuse that with being informed.


and nobody could hold me responsible, because I refuse to calculate the
orbit of the command module of Apollo 11.

So basically, you've got a lot of hot air....but nothing to support it.

Typical conspiracy theorist....long on talk, short on facts.

OK. You seem to insist on something more profound ;-(.

As I said, that needs some sort of work. So I relocate from sofa to
desktop and try to figure that out. But - please - a few days are
necessary, what is certainly possible ?

Sofa to desktop? Doggy's couch (sofa) is my WebTV comfort zone.
