If you count the atmosphere as part of the Earth, then the fastest speed would be either the X-15 rocket plane whose official top speed is 2905 mph (set in 1961 and may be considered at least partially a spacecraft ), or the Russian Mikoyan MiG 25 "Foxbat B" which has a top speed of 2385 mph. . Guiness accepts the MiG as the fastest operational combat jet. The fastest car, according to Guiness book of world records is 763.055mph on Oct 15 1997 by Andy Green of the UK. The car was the jet powered Thrust SSC. The wheels were passive. For a wheel driven car the record is by Don Vesco in the Vesco Turbinator in Oct 2001. The speed was 458.546 mph.

I believe the land speed record is 763 mph.
However, if you are talking about within the atmosphere of Earth, the space shuttle travels around 17,000 mph (Mach 23+/-) upon re-entry and slows from there.

It is 15,000 mph(25 times the speed of sound).And with the use of a space shuttle.But outside earth's orbit,i think its the saturn rocket used to go to the Moon.Used by the Apollo Missions.

Richard R.: The top speed of the X-15 was mach 6.7, or 4,520 mph, set on October 3rd, 1967.
And the SR-71 has a top speed faster than mach 3.2, however it's official top speed has never been declassified.

what occurs is that the gap station is pulled down by technique of earth's gravity. it remains the position it is because it is inertia motives it to bypass ahead far sufficient to easily stability the falling in route of the earth. in case you imagine about it, because it is going a million/4 of how around the earth, the earth's gravity has led to it to bypass from 0 mph to 17,500 mph, in a sparkling route. (at accurate perspective to the route it became going a million/4 revolution in the past.) it is 220 miles up because it is far sufficient that there's no significant air resistance, even if the gap go back and forth can nonetheless attain it. if it were better, it would take better gas to achieve it, which may shrink the payload that the go back and forth might want to carry as a lot because it. curiously, as you bypass better, it takes better means to get there. even if the speed you bypass isn't as severe. the means that it took to get there is kept as means means, fairly of dynamic means. geosynchronous satellites look to stay in a unmarried spot above the earth. they're 22,000 miles above the earth, yet basically go back and forth about 3,000 mph. the gap go back and forth might want to not in any respect get that prime, even if, if i keep in mind properly, the gap go back and forth has taken one of those satellite tv for pc (and booster rocket) up, then released it, alongside with the booster rocket, to positioned a satellite tv for pc as a lot as an orbit that go back and forth might want to not attain.

18.6 MPH.
Or... did you mean in some sort of vehicle?
