Actually, this question should not be asked at all. At the moment only those do, I’ll be quite frank, who just want to put on a big show, or simply away, are professionally untrained… or even more simply put, the brain cups are no longer completely there.
There is no means of transport that could survive this journey, and the destination is simply too far away. For it is a journey within the solar system.
As a reminder to those who have heard about it or have been on it themselves. (On TV or radio) to the moon one still flew with a small capsule…..there and back a few days.
To Mars you need real spaceships with an appropriate rocket propulsion and the journey takes a few months, about 6 of them…minimum.
Furthermore you need equipment to keep the crew alive. Simply said „a giant spaceship“ !!!
Now to some additional dangers for a possible crew.
There are some super small rocks that fly around a lot. If there is such a mini chunk with only a few thousand „second kilometers“ on a fast spaceship, I dare not describe what will happen.
„The outer hull of the spaceship would be destroyed.“
But let’s turn away from this case and say… it’s not happening.
Ever heard of cosmic rays? When the sun explodes, something like that is released. Extremely dangerous for the crew of such a spaceship.
But go on to say „It’s not happening“ ?
Let’s talk about the psychological problems that arise on such a long journey! No, I don’t want to talk about it, I’m not an expert : …but the problems are guaranteed.
Now let’s just say they have landed. But now we are facing something much more catastrophic. Mars has no magnetic field!!!!!!
That means that cosmic rays are coming unchecked to the people who travel with them. It comes to mutations, better „cancer“. So I suggest to use people who are at least 60 years old, the frequency of the expected mutations is then minimally lower.
In summary I say, one must not only build a suitable device to bridge the insanely long distance, but a greater consideration must be the equipment for an enormously good life expectancy of the space crew during such a journey.
As perhaps every reader has noticed, I am not a friend of such ridiculous stories!
Quite by chance something else at the times of such flights ………..!
If we assume that we could soon start a manned mission to the planet Mars from Earth, the shortest route would be open in a time window of about two years; about every two years Earth and Mars are especially close to each other. Since both Earth and Mars move on elliptical orbits, Mars is not always equidistant from Earth. The distance to Mars therefore varies between 56 and 401 million km. This is why ESA and NASA always launch their Mars missions when Earth and Mars are closest to each other.
How long do the missions take to reach Mars?“……let’s go a little further !
The Mars rovers Spirit and Opportunity needed just under seven months for the 2003 route – just like the ESA Mars Express Mars probe. The polar lander Phoenix which started in 2007 took almost ten months. Now to a „manned“ spacecraft, the flight time to Mars would be between 14 and 16 months or 420 and 490 days.
… to an assumed return flight to Earth from Mars
Should a manned flight to Mars take place, the question naturally arises: When can you return?
As with the flight to Mars, on the return flight one would have to wait until the distance between Mars and Earth is at its shortest to return to Earth. A stay of about 16 months on Mars or in an assumed orbit around Mars would therefore have to be planned. The total journey would therefore last about 1000 days….
………a really „ridiculous time“ …..was not ????_
