According to Mars One, an organisation that has been calling for applicants to make such a journey in 10 years' time, more than 150,000 people would be willing to make the one-way trip.
But one of the biggest barriers to visiting Mars is that it's not getting there that's hard, it's coming back.
Humans could have visited Mars or Venus in the '70s or '80s using variations of the Apollo spacecraft that went to the Moon. The catch was that they couldn't land.
Mars Direct, is a scheme championed by US engineer Robert Zubrin, which pulls a cunning trick proposing to sending two spacecraft to land on Mars, the Sydney Morning Herald reported.
The spacecraft the astronauts will fly home in goes first, empty and unfuelled.
Once it lands it automatically converts chemicals in the Martian atmosphere into rocket fuel that will power its ascent from the surface and voyage back to Earth.
