Onboard the SpaceX Starship 2.0 in Detail - What it takes to go to Mars | Detailed Breakdown

The layout of the ship follows two guiding functional necessities, zero-G environment, and low gravity. Logically each floor must be designed to accommodate these necessities plus, survival, and psychological needs of the astronauts. Naturally all life support systems will be located at the lower levels along with all hardware, tools among other crucial gear for the space journey and living on mars.
The top floors are for living areas and the flight deck.
A good starship design needs to follow simple rules. Easy to use and fix.
Problems that might arise throughout the journey need to be identified quickly and be simple to solve by anybody on board. If complex problems arise, crew anxiety and stress may lead into further problems risking the mission.
Lastly, everything on the ship must be monitored with visual information available on all floors, especially CO2 levels. User interface must be clear and simple to understand.

I am pretty sure they will not build a one-fits-all solution. Cargo will be send to mars ahead of time. The human transport configuration will only hold the supplies that are needed for the transfer. Also i do not expect to have a full flight control deck for all crew members. I imagine something similar in size to an airplane cockpit. Why would the system do need a lot of human interaction, if the starship is designed to fly without crew and carry cargo on its own anyway?

I was under the impression that the supply ships would be sent first, so the starship carrying the astronauts would not need everything for the full 5-year mission. Just for the journey to get them to Mars lightening the load.

This was fantastic. It is exactly the sort of info a sci-fi writer wants to have.

Nuclear power for the win.
Thanks for making this, I love it when airy speculation gets broken down into details that make sense.

You can reclaim oxygen, recovering 75% of it, and reduce the O2 requirements by several factors. Also, you can achieve over 90% water reclemation reducing the water requirements by 8-10x. this reduces the consuables of O2 to just 250gms / day / person, and water to less then a liter / day / person. even with a water budjet of 20L / day, 1 cubic meter of water / person would be enough water for 18months. 1 cubic meter of liquid O2 would be enough for 1 person for 12 years. The rest of your numbers seem to be close to the mark, and the production quality is realy spot on! good work

You also have to consider the EVA suits of each astronaut, if you plan on them going outside on Mars

Crew can also workout in gym room to create energy, in other word turning foods into storage energy, for various electric necessity in the ship.

That's really a good try at estimation, it highlights how difficult space can be, great insight.
Looking forward to seeing the following episodes..
Thanks.

One small thing I noticed- the chairs on the flight deck are oriented poorly for bellyflop reentry.

I was thinking, "They're going to need nuclear power", all the way through the second half of the video. Hydrogen cells, solar and batteries are never going to work on such a lengthy mission. Over time, hydrogen leaks through of all known materials. I would be very nervous about hydrogen tanks that were meant to last five years, or even six months, without serious leakage problems.

With nuclear, there will enough power to spare to split CO² back into carbon and oxygen. This means far less oxygen will need to be transported since it can be recycled from CO². With sufficient energy available, water can also be split into hydrogen and oxygen. In this scenario, the hydrogen doesn't need to be stored for long periods, minimising the leakage losses.

Recycling everything combined with utilisation of resources found on Mars will be the key to manned journeys to Mars.

I really love the quality of this video! And the topic too. Awesome work, Thank you!

[MichaelKubler-kublermdk]

This is awesome and very much what I've been thinking about. I've written 100+ pages of content about going to Mars and living there and just some of the technical challenges. The getting there bit is a big one that I don't think enough people have thought about. This is the greatest detail I've seen on the topic

[jamespayne]

Hey brother love your videos and I'm always excited every time I see a notification from you. Thank you for all you do and you keep making these videos and I'll keep watching!!!!

[cheesesvideosstorage]

I love this! Especially the final point at the end of the video. Sums it up nicely.

[RofelRolf]

As a 3d and Render Artist I´m thrilled by this dramatic illumination. Man, good job!

[brandonberchtold]

Great video! They likely would be able to tap oxygen directly from the main oxygen propellant tank though, so that would save a lot of mass from the oxygen tanks you factored in.

[SuperJompaVideos]

I love your space videos! Please make more of them!

[dackel]

I love these kinds of theory crafting and technology/number comparison! Paired with great graphics and voice over, this video really was absolutely incredible!

[fistpunder]

I'm starting to like your videos.This is the second one I have watched and I like your narration style along with the humorous comments you throw in for fun.
Nice work.

[LG-qzom]

Best technical details I've ever seen. Very informative.
