How long does it take to get to Mars?

If you wanted to travel to Mars, how long would it take? The answer depends on several factors, ranging from the position of the planets to the technology that would propel you there. 

According to NASA, a one-way trip to Mars would take about nine months. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.
