  1. As already mentioned, no molten core so no magnetosphere. No magnetosphere plus the reduced gravity means no atmosphere as the solar wind will blow any away created by man. Without an atmosphere with an ozone layer and UV will cause cancer (as was said on Earth justifying the elimination of ozone depleting refrigerants), What does that all mean? Life on Mars will require space suits and shelters. What will humans breath? Where will the oxygen come from? Where will the exhaled CO2 go. If converting CO2 to O2 is so easy then great, do it on Earth and climate change is solved!

    Bottom line – this is a ridiculous fantasy.

  2. I'd say the clouds of Venus have become infinitely more attractive for a potential Human settlement than Mars will ever be based on the technology we currently have or reasonably could have in the near future to make an off-Earth/Moon settlement feasible. The launch window for Mars is too infrequent; the transit times are far too long; Mars' gravity is much too weak for Human Beings; Mars is completely irradiated with no magnetosphere or dense enough atmosphere to provide any shielding, requiring habitats to be heavily shielded either by burrowing underground or bringing prefabricated radiation shielding from Earth along with. Mars is covered in its own regolith not unlike the moon except it has large dust storms that blanket the entire planet reducing access to overall solar power beyond the reduction due to Mars' overall distance further out from the Sun…(?) & That doesn't even take into consideration the losses of entire missions Humanity has collectively experienced in the pursuit of studying Mars — the Soviet Union struggled with Mars so much, they eventually accused the United States of sabotage. The US has lost projects sent to Mars. Even Elon missed trying to put a Tesla into Mars orbit!

    Venus, however, is right there — our sister planet! Sure, on first appearances she's ugly as sin, but we've mostly always been looking from the wrong angle. But if you look at the atmosphere, you find the most Earth-like conditions that we know of (except on Earth) in the entire solar system. Mars is an irradiated dusty cold wasteland; Venus has the most Earth-like conditions that we know of in the SS…(?) Why is Mars even being considered…?!! We should re-orient all efforts to focus on Venus & not Mars ASAP!!

  3. Robotics can survive on Mars and build out a Mars colony for humans. This is more realistic than sending humans to build a colony.

  4. The quest to find another planet in not one of scientific exploration, it's a desperate attempt to escape Judgement Day. Scientist are atheist, they know they believe there will be a reconning and are planning accordingly. They hope by leaving they can escape the wrath of God

  5. You all can have that. As bad as you think the earth is for climate change (the myth) it’s 1000 times better than Mars. You go ahead. I’ll wait here and watch it on YouTube.

  6. Edomites have not yet made it to Mars and already making a mess. Polluting space with earth junk, and here now polluting the Red planet with failed after failed landers. SMH. Esau is the end of earth and Mars. 😂

  7. Mars is a money pit. Bacterial life exist everywhere in the universe. We arent special. Please leave others alone. We have already failed as environmental stewards. Let god sort them out

  8. No we aren’t. We’ll never make it off Earth. Interstellar travel is impossible and even if it was we would never be able to find a suitable planet to colonize. We’re stuck here until a mass extinction event happens that wipes us out.

  9. We can explore there. That's all. There is no magnetosphere; never will be… ever. Therefore no atmosphere, ever. Therefore no colonization, ever. Ironic we are doing a bang-up job of destroying the one thing keeping us alive here, only to hope to go where there will never ever be a radiation defense. As long as we believe like lemmings, we shall die like them. Period, the end.

  10. Everyone saying we won’t go there? We have the ship design and everything we just need to get the cost per ton of cargo wayyy down, because you have to bring the whole colony at once instead of bits a pieces. The sole reason we haven’t gone yet is because we are trying to get the cost per ton down which is estimated to take 10-15 years. Elon said it himself technology isn’t the problem it’s that it’s 1 billion dollars per ton of cargo, and you need many many many tons of cargo 😂

  11. to surrect planets is how to live in a universe – mars belongs to life

    melt large amonts of ice with reflectors, water absorbs dust and radiation as heat, boiloff be greenhouse insulation and atmospheric pressure – once it rains fish can survive mars nature

  12. Instead of spending billions of dollars on Mars and waste a lot of precious time to renovate this red planet and say, "We don't have much time", why not just spend billions of dollars for saving this precious planet while we have a chance??

  13. Like Elon had saying to the twitter employee you need to be hardcore, like those bacteria and worms that lives inside our annuses, eating shit and breathing farts,if you don't like that you can always resign, but don't forget the air isn't free on Mars also the ride back to earth, so prepare for another 20th years of indeture servitude if you want to have a chance of being a poor and homeless person back on earth.

  14. Low gravity is the least of the problems. Soil for agriculture would have to be sourced locally. Unfortunately, the regolith contains enormous amounts of perchlorates, which are impossible to separate and toxic to life, human and plant. Suitable food crops would have to be designed to be tolerant of these chemicals and to exclude them from the portions designed to be eaten.
