What is the fastest speed ever acheived by any man-made veichle?

Answer 1

The space shuttle has an top speed of Mac 28 (28x the speed of sound), and its the most complicated vechile built EVER

Answer 2

Depends on what you mean by vehicle.

If you mean anything, you could say the molecules we can launch at speeds near the speed of light. If by vehicle, you mean anything carrying a human, that would probably be the Saturn V, the rocket that took astronauts to the moon. It had over a billion horsepower.

The man above me is wrong, however; the Space Shuttle doesn't go fast enough to break Earth orbit, a speed broken by the Saturn V, the Saturn 1B, and a number of passengerless rockets.

Answer 3

Since a vehicle is something designed to transport passengers, the Saturn V rocket leaving earth orbit would be fastest - about 24,500 mph. The Space Shuttle, not designed to leave orbit, reaches only about 17,400 mph.

There are unmanned spacecraft which have achieved significantly higher speeds. The record for any man-made object goes to the Helios 2 spacecraft, which reached a velocity close to 150,000 mph.

Answer 4

This was the fastest I could find
"the Galileo Probe''s approach to Jupiter in 1995, "The Probe was the fastest man-made object ever. Decelerating from 106,000 to 250 mph in four minutes"

Answer 5

New Horizons at 56,000mph. Helios doesn't go that fast relative to the Earth. You can claim your going 68,000mph just standing on Earth if you want to. Galileo never went anywhere near 106,000mph and if it had decelerated to 250mph it would have crashed into Jupiter.
