If you launch the payload from space, it probably would take very much, would it?

Like I said, you have to get out of the Earth’s gravitational well (about 7000 mph above orbital speed) and then negate most of the earth’s orbital velocity (an additional 67,000 mph) for a total delta-V of **74,000 mph**. IOW, it’s 4 times harder to go from low earth orbit to the sun as it was to get to low earth orbit in the first place.
