I stated this the other day on the site formally known as TDW.
Imagine you are at a friends house hanging out one night and their 4 year old son comes running down the stairs crying about the Boogie Man being under his bed.
Now normally you would expect your friend and his wife to console the child telling him there is no such thing as the Boogie Man.
Now imagine instead of consoling the child the mom grabs some lighter fluid and the dad grabs a gun. They run upstairs light the bed on fire and shoot 10 rounds in to it. That would make most wonder what the hell do they know about the Boogie Man that I do not.
Now this is what I am seeing form the left on Q. They are lighting the bed and shooting over and over.
The thrusters are not running/burning fuel during the entire trip. Only need thrusters to get going to a set speed and then cut them off for 99.9% of the trip. The Saturn V rocket launched into orbit and then started the journey to the moon before detaching. The trip to the moon took 3 days without any fuel being burned during that time. The Columbia command module was the only part to return from the moon and required very little fuel to get to speed heading to earth.
So, you can fire rockets in a vacuum? Interesting. And you can also propel in one? More interesting.
Yes. The burning fuel / expanding gas provides the propulsion in the opposite direction the rocket travels.
Also, there’s no drag (wind resistance) in a vacuum like there is when flying through the atmosphere.
Odd, they haven't been able to duplicate that in a vacuum chamber.
