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

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.

The best solution, as was mentioned, is to have unmanned construction machines go to Mars, have them build a base, preferably carved inside a rock cliff of a lava tube, and have multiple ships, each carrying a small number of people. Also, an amazing amount of materials could be gotten in-situ on Mars, oxygen, carbon dioxide, etc., and water could be made from those, assuming lots and lots of frozen water doesn't already exist there

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

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

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

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

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

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.

Fascinating yet so scary, I cant imagine living in a pod for 7 months, weightless, and with very risky components and possibilities. Much respect to the brave astronauts

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.

That was absolutely fascinating to watch!

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!!!!

Perhaps someone else has pointed this out: this is not Starship 2.0 that you are discussing; it is Starship version 1.0. Starship 2.0 is only a concept on paper. 2.0 will have double the height of version 1.0 and double the width to 18 meters (roughly 60 feet in diameter). It’s carrying capacity will be roughly 9x that of version 1.0. And there’s no way the development of Starship 2.0 will seriously start within the next 5 years. Otherwise, I agree with most of what you state about using starship (now 1.0) on a trip to Mars. However, there are known work arounds to some of the problems you mention, including unmanned robotic cargo missions to go to Mars ahead of time to set up a base for Astronauts to later arrive. 14 crew members on first trip to Mars sounds about right. But as the base is established and quirks are worked thru and fixed. The number of people on Starship can drastically be increased (not nearly as much as Elon would lead us to believe).

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

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

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

Very happy to see someone else doing this. However that said, I'd like to give some constructive criticism. (1) Don't do zero-G all the way to Mars--at a minimum connect two starships by the nose and rotate; (2) Don't need that much exercise equipment--they will share; (3) The flight deck could be reconfigurable for multiple uses--I suggest a classroom, lots to study en route; (4) Forget dehydrated food--use MREs + hydroponics; 1 MRE is 3-4K calories so one per person per day; (5) Obviously, you are going to recycle air and water--Mars has at least 1 liters of water ice per 1 cubic meter of regolith; (6) 600 grams of algae can exchange enough CO2 to Oxygen for an average adult, it can also clean ammonia and metals, a moss wall can do similar but directly from air as where algae will require spraying through air to capture it in water; (7) I don't think its going to need nearly as much electricity as the ISS, unless it's conducting numerous experiments and such; (8) water and plastics are great radiation insulators, yes. Also, foam the plastic and use as insulation. I suggest PVC, which will give similar radiation shielding and better insulation. Metals help block radiation but release secondary particles even more dangerous. That said, the plastic and water will block it.

You worked out many constraints. Very good! The "belly flop" reentry phase means that seats need to swivel from down-toward-the-bottom-of-starship to down-toward-the-belly and back in a few seconds. This constrains the configuration of landing seats.
