calculates a speed or velocity change based on how much of the rocket's total mass is fuel—the more fuel you have the faster you can go—and how fast it can burn this fuel. In fact, the equation is still used to this day.of altitude and horizontal velocity. To reach an orbit around the Earth you need two things. The first is to be traveling fast enough horizontally that you reach the curvature of the Earth before gravity pulls you to the ground.
To reach these speeds, you have to use very specific fuels and engine shapes, relying on the combustion of solids or liquids. As the fuel is heated and turned to gas it takes up a larger volume, and as such is pushed out the back of the engine, generating thrust. The more gas you can produce at higher temperatures, the faster your rocket goes.Hughes intends to use water as the fuel itself. The problem with water is that it does not boil quickly—it has a high specific heat capacity.
This is a very respectable height to reach on a homemade engine. But Mount Whitney, which is close to Hughes' launch site in California, has a peak of almost 4.5 kilometres . Neither altitude is anywhere close to the edge of space. It is not even high enough to see the curvature of the Earth, which requires a minimum height of about 10 kilometres .
This is no easy feat as it would require a fuel tank with a volume of 30 cubic metres, which is roughly the carrying capacity of two long wheel base vans. The increased size of the fuel tank and supporting structure would then increase the final weight, which in turn would require even more fuel. The engineering required to contain the internal pressure of this water and turn it instantly into steam may be very difficult.
ScienceChannel Not seeing anything capable of reaching escape velocity... 😆
ScienceChannel Será que um terraplanista vai ter um programa espacial melhor que o do Brasil? Ac Cardoso
ScienceChannel Who cares?
ScienceChannel No

Did the rocket launch happen yet? Can't find any news.
🤔He should aim for the end of the sky. That's right above the earth's edge. Once he passes the end he'll be in space. Less costly than burning all that fuel to go up.😏🙄
Stay tuned after these messages...👽
This loon is going to end up killing himself. If he really wants to see Earth's curvature, he could accomplish that in a balloon.
LOL
