The correct estimate for traveling from Earth to Mars is approximately 6 to 9 months, depending on the specifics of the mission, including the relative positions of the planets and the spacecraft's speed. The most commonly referenced duration is around 6 months, which is achievable during a mission utilizing the Hohmann transfer orbit, the most efficient path that takes advantage of the orbital mechanics between Earth and Mars.

Traveling to Mars typically requires launch windows during which the two planets are optimally aligned, which occurs roughly every 26 months. For example, the journey of NASA's Perseverance rover took about 7 months, affirming the close approximation of 6 months.

While 10 months is on the upper end of the estimate for some missions, it is primarily related to slower spacecraft speeds or variations in paths taken rather than a standard expectation. Longer durations, like 1 year or 2 years, would not apply to conventional missions and would result from impractical trajectories or extended stay in orbit around Earth before embarking, which does not represent typical interplanetary travel.
