How far is the flight to Mars?

Mars is on average 225 million kilometers from Earth, depending on the planet’s rotation around the Sun. An unmanned spacecraft flying to Mars would cover the distance in 128-333 days to reach the Red Planet.

Mars One said their projected flight would take seven to eight months. Currently, astronauts rarely spend more than six months on the ISS.

A flight to Mars would take more than six months, and astronauts would spend all that time in a highly confined space, deprived of many comforts. They won’t be able to bathe, eat canned food, and hear the constant noise from the fans.

Most likely, this flight will be a one-way trip, so great challenge for future “marsonauts”.
