About how long will it take to travel a trillion miles in todays most advance spaceship?

Well, the voyager probes launched back in the 60s or 70s have only gotten like a billion or so miles out from Earth(estimating). But using today's technology, we could probably catch up to the voyager probes in say a decade if we gave it all we had. You have to remember that there is not any oxygen in space to burn, so we have to use other forms of propulsion that do not require O2. What we could (or even should) do is create a huge rail gun out in space, and magnetically propel satellites out to where we need them around other planets and such. It would use MUCH less fuel to get them there probably due to having virtually no friction or resistance to motion when out in space.

The fastest space craft ever is the New Horizons unmanned space craft now on its way to Pluto. In a few years is will pass Pluto at 27,000 MPH, which is 7.5 miles per second. At that speed it would take 4,228 years to go one trillion miles.

The fastest space ships we have at this moment (do not include the Mars Mission or the up coming Lunar Mission - those space ships are not built yet) travel between 25,000 and 50,000 Miles Per Hour. 1.000,000,000,000 Miles Divided by 25,000 Miles per hour = 40,000,000 Hours or 1,666,666 Days or 4,566 Years Traveling at 50,000 Miles Per Hour, the time would be half as much or 20,000,000 Hours or 833,333 days or 2,283 Years Regards, Zah

Voyager II, launched in August 1997, is currently the fastest man-made object. Voyager II was still capable of sending data back to earth after recently punching through the heliopause (the boundary of our Solar System). Speed was calculated at 700 kilometers per second. And, it took ten years to accelerate from 166,000 mph -- geo-stationary earth orbit, or 1500 meters per second.

We can accelerate small probes to about 25km/s. We could probably reach close to 100km/s two generations of ion drives down the road when we couple them to a thermionic generators or small nuclear reactors. So that's 10^12miles/60miles/s=528 years. Bon Voyage!

The fastest know spacecraft to man is Voyager 1, traveling at around 17.4 km/s, converted to mph is 37800. A trillion divided by 37800 = 26455026.4455 hours or 3019 years phurface

I am sorry to cut the conversation short, but the amount of fuel needed to travel that fast would be so immense. It doesn't exist, and would weigh down any craft so much that it would never leave the earth.

gg is correct. We have no technology that would allow humans to travel a trillion miles. Not even close. The fuel requirements would probably be in the millions of supertankers range.
