I’m just wondering if there’s a way to use Earth’s rotation to help leave orbit, without such large booster rockets?
Conceptually speaking, if you could go straight up, while the Earth rotates below, you’d eventually could go into space.
Rockets already use the Earth’s rotation. That is why they preferably launch to the East rather than to the West.
Take a class in Newtonian physics and get back to me.
Well if you could just stand still you would quickly be in space as the Earth continued in its orbit..
Electrically, rail guns and coil guns. The problem here is the rate of acceleration would turn most organisms into pancakes unless employing a VERy long rail/tube. These methods, esp. rail guns, require massive amounts of current, on the order of mega-amperes.
A hybrid of conventional jet turbine engine technology, scram jet, and rocket could get one to space starting from an airport.
Lighter-than-air solutions (balloons/dirigibles) could conceivably play a role. Imagine a lighter-than-air airport at 50,000 feet ASL.
More futuristic modes like macro wave galaxies and teleportation are beyond our 21st century horizons but may someday be feasible.
Yes, there are indeed MANY options besides the "obvious" booster rocket approach; commercialization of space exploration brings the creativity of the free market to bear (in sharp contradistinction to the President's position that "it takes government" to accomplish such feats).
Kudos for your creativity and alacrity to think outside the box.
That’s why you lauch a rocket from as close to the equator as possible. The Soviets had to build heavier lift rockets than the US, since we could launch from much closer to the equator.
This is what is done now. Launch sites tend to be near the equator where rotational speed is greatest (about 1,000 miles per hour at the equator) and launches are toward the east to take advantage of the rotation of the Earth.
L.P.
“I’m just wondering if there’s a way to use Earth’s rotation to help leave orbit, without such large booster rockets?”
They do that now by launching from florida and launching to the east.
The earth’s rotation is used for a boost, which is why they launch as close to the equator as possible on an eastbound trajectory.
