With current technology, a one-way trip to Mars takes about 7 to 9 months depending on the alignment of Earth and Mars.

Estimated Duration: 219 days

Traveling to Mars depends on the positions of Earth and Mars in their orbits, known as the Hohmann transfer orbit, which occurs roughly every 26 months. Current propulsion systems, like chemical rockets, require about 7 to 9 months for the journey. Future advancements in propulsion, such as nuclear or ion drives, could reduce this time. Factors like fuel efficiency, spacecraft speed, and mission design also influence the duration. NASA and SpaceX are actively working on improving transit times for crewed missions.
