What will it really take for a Mars human mission? - SpaceX's Mars Plan

Have a great week everyone! For those interested in the presented Curiosity Stream episode, you can check it out at Curiosity Stream at curiositystream.com/marcushouse If you already have it, the direct link to the episode is curiositystream.com/video/1144.

“Being socially isolated for months or years” introverts, “I’ve been training my whole little for this!”

I’m always looking forward to watching your videos Marcus, every Saturday I pick up my phone and wait for your videos, but then there’s the unexpected mid week video! Can express the appreciation enough for the extra effort.

I was 4 years old when Man went to the Moon for the 1st. time, and I remember running outside after they landed and looking up at the moon and knowing they were there was such a trip.

I find the issue of eye problems induced by long term zero G an interesting one. Not like any Mars colonists can see an optometrist or ophthalmologist out there, I think there's a very real risk of several Mars dwellers getting intractable vision loss or even blindness on a Mars mission

As usual, a magnificently assembled plethora of intellectual ideas and information. You sir, have once again, along with your crew, outdone yourself. Thankyou

It is worth noting that although artificial gravity solutions will exist at some point (I assume) which spin to create that centrifugal pressure, it is simply not practical with Starship. I imagine you would nee nuclear propulsion on a massive rotating transfer vehicle that simply travels between Low Earth Orbit, To Low Mars Orbit and return to LEO to be refilled. This is something humans won't tackle for a lot longer. Certainly not within the next decade (would be nice if I was wrong about that).

Hello Marcus. I was, at 17 in 1969 the youngest accredited journalist to view the Apollo 11 Saturn V liftoff at the Cape. Truth is I was a high-school student in California who had a friend and whose father was Editor of the local newspaper and who gifted me an introductory 'he's a journalist' letter for NASA. I live in Florida now and am the father of an 8-year old who loves to spend her spare time checking out Galaxies and Black holes and who will, hopefully, get to witness many StarShip launches. Marcus I think you do a great job. My entire life has been literally praying for what is currently happening regarding space and Mars and I wanna see us go to Mars before I die. Keep up the great work. Regards, Bruce

It's worth mentioning that you estimate 1000 mSv over 30 months for a mars trip, and that yes that is far higher than humans on Earth get on *average*, but citizens of Ramsar Iran might receive up to 650 mSv in that same amount of time. So the differences there may not be as dramatic as the "65x the average on earth" statistic makes it out to be.

Well done on this special mid-week video. I’ve watched it several times and learn new things each time. Great research, production and delivery.

I particularly enjoy how Marcus makes positive remarks about all the rocket activities of different companies, even the ( how should I say ) interestingly unexpected functionality outside the optimally intended design objectives, which yield valuable data for evolving the next iteration. After all, rocketry is not easy. :)

In-depth on each aspect of this episode would be great! Thank you so much for your hard work!!

Let's hope he can do it in his lifetime, people walking on the moon and mars would be another awesome milestone for this century.

Love the Midweek content Marcus, I was hoping you would do it as a lot of channels have been going that route with Documentary style Vlogs and I am enjoying yours, from South Africa. Thanks for all the informative and engaging content.

Great video, as always. Whenever I hear of "difficulties of space travel/colonizing Mars", etc., I remember the quote from Jim Lovell: "It wasn't a miracle that we landed on the Moon. We simply decided to go." We as a species decide on what are important challenges. Once we make up our minds and focus our efforts, we can probably eventually do just about anything.

Hallelujah! Bonus Marcus! Thank you.

I learned so much from this video, Marcus! Thanks for the bonus mid-week video and as always love your weekly videos, too!

I love seeing your program normally, but this one with the plunge into the possible problems that we can count on the travelling and stay in Mars is really well don, congrats 👏🏻👏🏻👏🏻👏🏻👍🏻

Dear Marcus, thanks so much for offering such thoughtful space updates every weekend; this video is a great reminder of what it will take to design and engineer human missions to mars. Let's hope development of necessary capabilities turns out successful in the next decade or so! Best regards from a space follower from the Netherlands- Stefan.

You failed to mention how robots would need to arrive first and build habitats first which would take years. Sending humans to an unprotected surface on Mars is a death sentence and it will never happen that way. There would be no way home without a launch pad.
