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.
Originally Answered: How long does it take a spaceship to travel one light year? The fastest spaceship ever relative to the Earth was the Juno probe at 265,000 km/hour. A light-year is 9.461 Ã 10^12 kilometers, so it would take the Juno craft 4072 years and 240 days to travel that far.
