How long would it take to get to Mars?
Data as of July 2026
6.9 yearsby jet, without stopping
Mars comes within 55 million km of Earth at closest approach. In a straight line at airliner speed that's 6.9 years of continuous flight. The fastest spacecraft ever launched would need 39 days.

The honest timetable
Family car (100 km/h)
62 years
Jet airliner (900 km/h)
6.9 years
New Horizons: fastest launch ever (58,500 km/h)
39 days
Light (299,792 km/s)
3.0 minutes
Those are straight-line times at the moment of closest approach: the absolute best case. Real spacecraft can't fly straight there: they follow long curved transfer orbits, sling around planets for free speed, and have to slow down at the other end. Real Mars missions take about seven months: Perseverance flew for 203 days in 2020–21.
Olympus Mons rises ~22 km, about 2.5× Everest, on a planet half Earth’s width with a third of its gravity.
