But what if there was a way to speed this up without needing new types of advanced technology?

Now, in a new study, cosmologist Marcelo de Oliveira has put forward a potential solution - one that essentially makes smarter use of orbital mechanics to get to Mars a lot quicker.Because spacecraft follow curved trajectories shaped by gravity, their paths can be subtly adjusted by careful timing and routing. By choosing specific launch windows and optimizing the spacecraft's route through space, it may be possible to significantly reduce the travel time.

One way to achieve this is to use asteroids as gravitational assists, slightly changing the spacecraft's speed and direction without extra fuel. When combined with other trajectory adjustments, these small changes can help produce a faster overall route to Mars.

Taking all this into account, a really well optimized route could knock several months off the travel time, though at the cost of additional navigational complexity and technical challenges.

Even so, such optimizations could one day make a manned mission to Mars a lot more achievable.
