And as I said, I never did qualify myself as a rocket scientist. You did.

From where have you and STOMPK attained your degrees and for whom do you work at present?

NASA?

See, you were the one saying I am a rocket scientist. lol

Well, let me ask you this....do you think that a rocket motor operates by pushing against air, like a fan, or through the ejection of matter?

Well...all of this has been about you attacking me for correcting the guy on his physics understanding, so I am assuming you must have a position on it. Do YOU think that the whole ISS/space shuttle thing is a hoax?

Right, you just said that I was unqualified to post any info on how rocketry works because I am not a "Rocket Scientist". Funny. Do you ever contribute any substantive rebuttals in any of your postings?

Kind of pointless seeing as you cant see "any benefits from the space station". Such short-sightedness is alarming. Perhaps you should google their press kit sometime. Well, goodnight, I am off to do some thing more productive....like my girlfriend.

Newton's Third Law of Motion states that every action has an equal and opposite reaction.

Contained within the Third Law is also the law of the conservation of momentum.

As exhaust is thrust out of the back of the rocket this exhaust has a momentum which is equal to its mass multiplied by the exhaust velocity. It follows from this that the higher the exhaust velocity the greater the momentum of the rocket exhaust and hence the greater the thrust.

Because of Newton's Third Law half of the momentum of this rocket exhaust will be used to push the rocket in the opposite direction.

If you know the rocket's mass, the amount of fuel burnt per second and the exhaust velocity then you can calculate the rocket's gain in velocity per second interval which is also therefore equal to its acceleration.

Does this clear the issue up for you?

If you cant understand that simple, clear explaination then you have no room criticizing.

Good job Galax!

I have a small observatory at home - can tell you that the ISS is a certainty.

You can see the ozone in pictures recorded by NASA from the shuttle.

What you have to also remember that cameras cannot determine light in the same way in space because light behaves different.

I the same sense a picture on the moon will not reveal any stars and if you try to take a picture of the night sky on earth with a standard camera - you will get nothing but black!
