Traveling at approximately 29,000 km/h (18,000 mph) the shuttle orbits Earth every 90 minutes. By using current technology and a spacecraft powered by chemical rocket engines, a trip to Mars could take between six to nine months.
How fast can we humanly possibly go in space? I was just reading the news about the launch of the probe to space heading to Pluto about 36,000 mph. Can we go faster if we can push the momentum to let say 100,000 or 1,000,000 mph? Can the humans withstand that type of speed in space? After all I see astronauts in earth's orbit doing spacewalk going about what 8,000 miles per hour? I forgot so anybody can help correct me.
