(Okay, we'll try to stop saying Benjamin.) For the results, Kayak looked at both domestic and international round-trip flights in economy class; evaluating search dates between July 1, 2016 and June 30, 2017 for travel dates in that same period. Of course, What are the cheapest days to fly? is a complicated question.
A Russian Soyuz capsule usually takes at least two days to rendezvous with the ISS, because of the carefully timed dance of manoeuvres that must take place for a spaceship to safely meet the orbiting laboratory. Using a new launch process, three astronauts have now made the trip in just under 6 hours.
How long does it take to travel to Mars? The trip takes around seven months; a bit longer than astronauts currently stay on the International Space Station. The precise duration of each journey depends on when it is taken. Because both Mars and Earth's orbits are not perfectly circular, the time it takes to travel between them varies from six to eight months.
