At 99.999999999999999999999999% of the speed of light, just like everything else that has mass.
But also take in account acceleration, safely the fastest speed to accelerate is a constant 2g acceleration without killing your astronaunts.

Yuri Gagarin
A monkey is close to a human so it was to see how a human type system would react into space. Plus, if there had been an accident a monkey would have been lost and not a human. Monkeys can also be trained to do things that would be needed as well.
A space shuttle can travel at speeds of up to 17,500 miles per hour (28,160 kilometers per hour) in orbit around the Earth.
My answer is that space probes go 5,075 mph, when launched from Earth. Hope I helped you find your answer.
It depends on where in space they are but they often travel extremely fast, upwards of 11 km per second
That special gear that has been developed for human space travel was the space suits. The space suits kept human alive in the harsh environment of space, temperature extremes and vacuum.
Fast enough to cause a big spolosion

To see if it was safe for a human to travel into safe. If the monkey made it, a human might survive space travel. If the ape died, then it was not safe for a human to go into space. The chimp lived, so human beings were sent into outer space.
The best fictional way to travel through space fast without messing with time is teleportation.

They travel through space at the same speed that Saturn travels.
