Question by : Space craft fuel help?
Is it possible to get a 747 sized space ship to space using VASIMR engines’ The ability to fly up 60 000ft’ And light weight.
Only using 10 million dollars of fuel
Answer by Morningfox
Do you mean the ability to fly to space from 60,000 feet, or to reach 60,000 feet from the ground? I think that 60,000 feet is a long way from outer space. The accepted point is 328,000 feet. A 747 sized ship would need about 2,000,000 newtons of thrust, or maybe twice that if it was heavy loaded.
Current and near future VASIMR engines would produce less than 1000 N thrust. They would need to be 2000 times more powerful to get a space ship from ground to orbit. Even starting from 60,000 feet and 1000 km/hr would save only 5% or 10% of the total energy.
It *might* be possible to get something as big and heavy as a 747 to orbit with only million of fuel. The Space Shuttle costs about million per launch / landing, but that includes a lot more than just the fuel.
Space Shuttle payload = about 30,000 kg.
747 payload = about 113,000 kg, about 3.8 times more.
