A Manned Mission to Mars Is Closer to Reality Than Ever: NASA Chief. Such work should inform planning for crewed Red Planet missions, which could take astronauts away from Earth for 500 days or more, NASA officials have said.
Another SLS liftoff would then send NASA’s Orion capsule and a crew of four up to meet this preplaced gear, which would help take the astronauts to Mars orbit in a journey lasting 200 to 250 days.

SpaceX says it will put humans on Mars by 2026, almost 10 years ahead of NASA. Actually getting humans to Mars isn’t all that difficult. Yes, the journey is quite long (around 200 days) and there’s a risk of radiation exposure, but these are fairly small problems compared to a) landing on Mars, b) surviving on Mars, and c) getting back to Earth.
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 …
So with the shuttle, it would take six years just to get the supplies into space. For this reason, you would probably need to develop a launch system that could lift more than 50,000 pounds into space. Even with a better launch vehicle, it is unlikely that you could launch the Mars mission all at once.

NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.

Jul 19, 2009 · How long would a manned mission take to travel to Mars? And what is the biggest reason for the mission not taking place in the near future. We sent men to the moon 40 years ago so obviously the technology is there to travel to deep space.
