    • When Eric Trump said during Tuesday night’s RNC “and soon under my father’s leadership, it will send Americans to Mars,” I burst out laughing because of how ridiculously absurd of a claim it is. I’m not even joking. I literally burst out laughing. 

      For starters, the last time a human set foot on the Moon was December 14, 1972 during the Apollo 17 mission. We haven’t gone back since then. To think we’re gonna leapfrog the Moon in the next four years and send humans to Mars in and of itself seems far-fetched to say the least. 

      Secondly, there’s the dangers and risks of sending humans to Mars. We’re not even sure if it can be done. And if it is to be done, we’ll first start by going back to the Moon and experimenting with having astronauts live on the Moon for extended periods of time. Starting with maybe a month long mission, then two months, and then finally three months, which is the estimated amount of time astronauts are expected to stay on Mars if such a mission were ever to be pulled off. 

      The major challenge on this front is having enough food, water, clothes, and oxygen such that survival is possible. Then, there is the question of what prolonged time in space has on the human body. The Apollo missions to the Moon were 2-3 weeks at the very longest. The longest time a human has been in space is 437 days and 18 hours (Valeri Polyakov aboard the Mir space station from January 8, 1994 to March 22, 1995). In the case of Polyakov, he was in a station that hovered close above the Earth. That's not the same thing as being on the Moon or Mars for over a year. Before we send humans to Mars, we must first get a real understanding of what several months in space does to the human body. Especially on the Moon first.

      As a matter of fact, a manned mission to Mars would require astronauts to spend close to two years in space. Nine months going to Mars, three months on Mars, and nine months going back. The reason for three months on Mars is because you can’t launch to Mars and then launch back to Earth whenever you feel like it. You need to make sure the planets are aligned in the right way. 21 months in space is a long, long time for a human to be in space. Without sound knowledge on how that would affect the human body and doing clinical trials on prolonged Moon missions, a manned mission to Mars during a second Trump term or a first Biden term, would be irresponsible. 

      So, in case you furrowed your brow about Americans going to Mars in a second Trump term, your suspicions are more than warranted. They would be right. A manned mission to Mars will not happen in the next four years and based on my estimations, we’re probably at least a decade away if not more from such a mission. If such a mission is ever even attempted. 

    • Hey now, Mr. Science Denier. Matt Damon has already been there. I read about it in a Facebook group.

      In all seriousness, I would have said putting a man on the moon in 1969 with the tech we had then was clearly impossible. But we had a thing then that we don’t have now: a president who revered scientists. Think of this amazing dinner and the message it sent:

    • Yeah, that didn’t happen. Bush did touch on something important, though. Namely that before we attempt a mission to Mars, we need to experiment with extended periods of time spent on the Moon.

    • I haven't heard Elon say anything about going to the moon, have you??

      He only talks about going to Mars- or did I miss a chapter or something?

      The moon seems like a much more feasible goal and a goal with more immediate returns for citizens of Earth who will have to fund the missions -

      Mars is far enough we're not going to trade with Mars without a major new way to travel in space than we have right now. And as has been mentioned, we need to understand the changes in human physiology with extended time in space and zero G.

      Going to Mars is cool and exciting, but not very practical at the present state of technology.

      It might help answer questions about the origins of life and the history of the solar system, but those are not questions needing urgent answers at this time.

    • I haven't heard Elon say anything about going to the moon, have you??

      No, his 'plan' seems to be, and I'll admit I only skim read it, to skip the moon and go straight from earth orbit to Mars.

      Sending cargo ships first followed by multiple crewed ships which would all wait in earth orbit for a window and then fly to Mars at the same time.

      I think I read somewhere that his vision for monetising the whole thing is not from mining or trade between there and Earth but licensing and selling tech created on and for Mars.

      It's a bold plan and I'm not saying that it is achievable in anything like the time frame that Elon is talking about, but I'd be more willing to put money on something led by Musk getting there than something led by Trump.

    • Politicians come and go, moreover in the grand scheme of things, each of us have only one turn at living. When we drive, we look for close obstacle avoidance, while keeping in mind a safe arrival at a desired destination. We don't usually depart NYC hoping to arrive in Buenos Aires. Politicians have the ability to disregard any reality while promising literally the moon. It costs them nothing.

    • I have a lot of faith in Elon, I have been a stockholder in TSLA since last June, so I'm quite happy with its performance.

      Space X's perfomance in launching and re-landing launch vehicles is quite impressive as well. If it were public, I would be an investor at a reasonable price, if offered.

      I look forward to seeing successful exploration of the red planet - whether done by bipedal humans or quadripedal or wheeled robots.

      I just think that Mars is gonna be a one way trip for a long time - kind of like Australia was in the 18th century.

    • Really interesting video, but Terraforming will/may be carried out over many human generations - literally hundreds or thousands of years.

      And creating a stable orbital magnetoshield is even further in the future I submit.

      Will the folks living on Mars still be typical Earth humans then??

      Interesting questions to ponder, but we won't know the answers in our lifetime I suspect.

    • I think any talk of humans actually colonizing Mars is nutty stuff. I'm not saying it's impossible for certain, but it just feels like something out of a science fiction movie.

      As for people walking on Mars like they did on the Moon, I think it's highly unlikely, but certainly within the realms of possibility.

    • Btw, I feel like telling those who say colonizing Mars could save humanity that we need to start with saving our Earth and taking better care of it. That's our best bet.
