fastest speed reached by man?

[Glaucus]

Just been watching days that shook the world, this one was about the first supersonic flight.
It just got me thinking what's the highest speed that someone has traveled at.
I assume it's on the shuttle or another rocket. Any one know who it was which rocket and what speed they reached.

Found the fastest women

Highest Speed Reached By A Woman
Kathryn Sullivan (USA) achieved a women�s record speed of 28,582 km./h. (17,761 m.p.h.) on April 29, 1990, at the start of re-entry at the end of the STS-31 Discovery shuttle mission.

Which i just over mach 23

Who can beat my lacking google skills.

Apollo 10 was the fastest re-entry of all the Apollo missions.

As it hit the top of the earth's atmosphere and started slowing down, Apollo 10's command module, with astronauts Thomas Stafford, John Young, and Eugene Cernan inside, was traveling at about 11.1 km/sec, which works out to 6.9 miles/sec, or 24,830 miles per hour.

That's 39,960km/h or Mach 37.6

Thanks . that's in sane 6.9miles/s what's the stopping distance on that .

I hope by the time I become an OAP space travel is cheap.

Depends what you're measuring it relative to, you could argue we have all travelled at the fastest speed of 552 km/s, the speed of our galaxy relative to the CMB.

True but I was thinking more man made speed.

relativity tbh

So do I. I would love to travel in space, just to feel true zero-mavity if nothing else.

That's the fastest speed I can find ever travelled by a human.

If you're interested, a spacecraft called 'Helios 2' holds the record for the fastest manmade object @ roughly 150,000 mph.

It makes you appreciate the speed of light

The record for the fastest spacecraft of all is held by the twin Helios probes that were placed in orbit around the Sun. Both these vehicles reached top speeds of around 150,000 mph (250,000 km/h) at closest approach to the Sun in their highly elliptical orbits, Helios 2 being marginally the swifter.

What's that about 1.4% speed of light.

Light travels at 3x10^8 meters a second, so nowhere near 1.4%

Damn this reminds of a picture I saw someone took of a news report on US tv.

After the Columbia disaster a News station reported that before breaking up the shuttle was travelling at 18 times the speed of light guess anyone with high school physics was taking the day off!

opps I tried working it out withy miles/s and mph doh'

was that fox news by any chance?

How feasible is a rail gun to launch payloads into space?
Or does it require to much electricity atm to make it plausible.

that + imagine the g forces you'd put on something accelerating it to escape velocity in such a small distance, would turn most people to jelly, and wreck equipment i think.

Also theres the trouble with getting that many capacitors really close together and close to the gun (wires cause inductance which screws up the firing apparently)

people yes but not sure about equipment. I would imagine it be a relative cheap way to launch large masses into space.

To put it another way, whats the fastest speed a human could survive?

 

[Glaucus]

rofl how the hell did they get that so wrong.

To put it another way, whats the fastest speed a human could survive?

speed of light, as long as the acceleration isn't to hard.

 

[Tefal]

well as long as you accelerate slowly enough over a long time then, any speed up to light speed (assuming light speed is attainable/non lethal). Speed isn;t a problem it;s g forces/acceleration.
