Paul Wooster – SpaceX’s Plans for Mars – 21st Annual International Mars Society Convention

Paul Wooster – SpaceX’s Plans for Mars – 21st Annual International Mars Society Convention

And that brings us to our next speaker which is Paul Wooster from SpaceX he’s the principal Mars development engineer there and we’re very excited to hear his talk on SpaceX’s plans for Mars Please welcome Set that up there Thank you very much for for having me here I’m I’ve been actually kind of started my interest in Mars, you know back when I was about I guess nineteen years ago. So the Mars society is about you know 20 years old now I missed the the first couple of conventions but fairly quickly gotten involved in that I met Robert Zubrin And really was inspired overall by this vision for Expanding humanity outwards into the solar system, you know having having people living and working on Mars SpaceX as a whole is also, you know very much motivated by those types of Objectives. I’ve been there for 11 years working on a variety of different programs in support of this but really excited now to be quite Focused towards the Mars aspects of things So in terms of some of the things that SpaceX has been doing One of the quite recent things back in in February this year is we had the first launch of Falcon Heavy this is the largest operational launch vehicle and Offers a lot of capabilities in terms of enabling future robotic missions to Mars and elsewhere (So, it’s kind of a overview here)
It’s a god-awful small affair To the girl with the mousy hair But her mummy is yelling, “No!”
And her daddy has told her to go But her friend is nowhere to be seen Now she walks through her sunken dream To the seats with the clearest view And she’s hooked to the silver screen But the film is a saddening bore For she’s lived it ten times or more She could spit in the eyes of fools As they ask her to focus on Sailors fighting in the dance hall Oh man! Look at those cavemen go It’s the freakiest show Take a look at the lawman Beating up the wrong guy Oh man! Wonder if he’ll ever know He’s in the best selling show Is there life on Mars? All right, so Obviously a very very inspirational day. We’re all quite excited by that and you know, not just the launch but having our first payload Flying out past the orbit of Mars This is Starman here in the, uh you know, Elon’s red Tesla Roadster it’s now out past the orbit of Mars now and Gonna be sailing around through the solar system Until it, I guess eventually, you know Disintegrates or you know, it gets gets ejected or what-have-you, but will be out there for millions of years. I Obviously a very very iconic shot of the Falcon Heavy demo flight But you know in terms of overall accomplishments this too is also, you know quite impressive SpaceX we’ve got started with the idea of really reducing the cost of Launch and enabling much more activity to happen in space by decreasing that cost and very much fundamental to that is the reusability of our vehicles so What’s one of the things that’s impressive here is not only are these these two stages coming down and landing But both of those stages had been used previously so This is not not their first flight but a second flight and now with Falcon 9 With the latest upgrade to that we’re gonna be seeing even even increase Reuse on those vehicles Another key aspect of this is it enables the types of technologies that we’ll need to land very large payloads on Mars So in order to do that, we’ll be be performing propulsive landing and and using an even larger Vehicle when we’re talking about human scale missions there so that that brings us to the Work that I’m doing now focused towards BFR or the big Falcon rocket which has You know, even even larger payload capability as compared to falcon heavy and not only that is fully reusable So not only is the first stage Reused be performing, you know similar maneuvers to what what we do with Falcon Currently having it boost back to the launch site. But also the second stage what we call the the ship will also Be reused both For missions to Earth orbit and then out beyond that We’re making use of a number of lessons learned from Falcon but then also rolling in new techniques in terms of the ways way in which we’re Manufacturing the vehicle the propellants that we’re using we’re gonna be using methane oxygen across the board on this Which is again something that will help enable reduction in cost Improve reuse and of course in the context of Mars also allow us to make use of propellants that we can generate on the surface Overall, the vehicle has 31 engines on the the first stage the booster and then seven on the on the upper stage the ship and we’ve designed this this vehicle to not only be able to Fly to Mars but also address a wide variety of additional markets that can really help out Spreading the cost of having this system brought across many customers Zooming in on the ship down the bottom left. There’s a small little person there for first scale. But basically this is the integrated second stage combined with payload section So we have the propellant tanks the engines and then the payload area what we’re showing here is a configuration with a number of cabins in it for for transporting large numbers of people to Mars we also though have large cargo doors on the vehicle and the ability to Get payload back down both from the rear cargo compartments on it along with Capabilities in the front we have other configurations as well for even larger Payloads being delivering into orbit or elsewhere on the in this solar system the vehicle also You know for scale as said it there was the person there now here it is relative to a Tesla Model 3 This is the tool that we’re using to build barrel sections on the vehicle You know somewhat locally down here in San Pedro the You know, that’s me you You have the video great the Another another key element beyond building the structures is the methane oxygen propulsion as I was saying, this is one of several You know, we’ve been doing a lot of testing with our Raptor methane oxygen engines This is one one example of that there you can see the nice clean flame from that and also just a demonstration that you know sort of the type of capability we have to do long duration firings on that engine. To go from a fully reusable Vehicle and then and use that to extend outwards into the solar system. One of the key things we’re doing is propellant transfer So we’re basically refilling the vehicle with propellant that allows us to effectively Reset the rocket equation. So we go from getting a hundred tons or more into low-earth orbit then refill and we can take that payload Pretty much anywhere including, you know, surface of Mars surface of the moon or elsewhere To do that we’re taking an approach that we see as being you know relatively low risk early on where we’re Performing active settling such that the propellant can stay over the outlets and and transfer it over more easily And just generally speaking Taking advantage of some of the experience we’ve had with Falcon in terms of having liquid oxygen on board and long-duration Coast along with all of our experience with Dragon for rendezvous and docking and then, you know other work that’s that’s happened to understand these types of behaviors and Because we’re able to fill out the tanks again That can allow us to do all sorts of different missions so we can deploy Large satellites, whether they’re in low Earth orbit or elsewhere at the Lagrange points and so on I think that’ll have a number of opportunities in terms of you know Future telescopes and other missions having a 9 metre diameter fairing is quite helpful there We’re able to support Various on-orbit activities as well. You know, it’s a cargo and crew transport and then The way we’re developing this system is its able to you know? Not only go to Mars, but also the surface of the Moon and that’s where their common vehicle So it’s not something where we need to develop something that’s dedicated to one destination or the other but we can take advantage of all that work and achieve many different missions That said I think the primary interest of people here in this room is down the bottom-right for landing landing on Mars So the way in which we do that is we fill the vehicle up with propellant after we’ve launched it on Into orbit, we can basically get all that propellant up there with through a series of tanker flights Those are very similar to the ship that will be carrying cargo or people but just taking up propellant to fill up the vehicle But once that ship is filled up it would it would fly to Mars performs a narrow capture or direct entry Lands, and then we use in situ propellant production. So using local resources water from the ground co2 from the atmosphere combined with power to achieve the Process of making the oxygen and methane propellant for return of the vehicle. Ah s- this is kind of a pretty busy chart but it lists out a number of the key features of how we’ve been able to focus on an architecture that allows us to get to Mars with a low cost and Really to minimize the amount of development needed to make that happen So the full reuse is certainly, you know, critical to allow this decrease in cost But similarly we’re also minimizing the number of elements that we need to develop in order to make early missions happen You know as we go forward there may be you know future efficiency improvements that we’ll make but we’re very much focused on getting to Mars as quickly as possible and getting You know set up with a robust surface presence there So that’s how we we get to Mars That said you know while we SpaceX are very much focused on the transportation you know everything that’s gonna happen on the surface is quite important too. Okay, so In terms of what what will be needed on Mars. This is an area where SpaceX is quite interested in the capabilities here, but also something where I think a lot of people beyond just SpaceX can really contribute to these types of capabilities One of the critical things you’ll have to decide before you you go is where do you want to live? You know you what you want to have a place that you can land in safely so that really gets to a number of the hazards and Whatnot that you have to address there That’s how once you’re there you want to have useful things. So the types of resources that you’ll have available to you early on Water most likely in the form of ice is a pretty critical one, but then you know other other resources as you move forward and then just other things that will affect you there in terms of temperature and and And dust and other mobility considerations along with probably just having interesting things to do as well So we should certainly heard the number of you know things going on with Rovers and quite exciting as people get there as well. So Some some of the things that we’re looking at in terms of You know different regions on Mars. We’re very much For these missions looking for things that will have significant quantities of water ice. We we’ve looked at a number of different locations in support of that. There is very strong evidence for Quite significant quantities of water in the mid-latitudes. We basically, you know, there’s definitely ice up in the near the poles but balancing that against power and thermal Considerations and just general operational aspects would try to get you down closer to the equator But there are a number of regions where between morphological evidence radar measurements and then even in some cases Being able to directly image ice following a fresh impact crater We’re able to really determine that there is large quantities of ice and in these areas that said there will also be opportunities to further define that going forward and then of course some of these other considerations For what will be needed there on the surface including the safe landing aspect which again can you know rule out a site that was otherwise Looking great from resources and other considerations So once you Have a site in mind you would start start sending missions there. We we’re looking in terms of our overall Plan for this. Now, the timeline here is you know, a very sort of aspirational Version of things but as early as 2022 sending initial set of cargo flights We have the system set up such that we can send multiple vehicles per opportunity, so Normally sending at least two cargo missions. They would be you know, in terms of some of the objectives there is really: confirm water resources and the locations that you’re interested in and then determine any hazards for future missions and then start to put in place some of the infrastructure that you’ll need Subsequently in the following opportunities. So basically the opportunities to go to Mars are about every two years 26 months just based on the relative motion of the planets I would send two more cargo ships and then also two two ships with the first people to go to Mars where they would be really focused on getting the initial outpost set up get going on all the resource work that will be needed to Both provide propellant along with expand the base for future activities there in terms of some of the questions about resources understanding that both vertical and Horizontal distribution is quite important when you get there knowing if you know you’re dealing with relatively pure ice or something. That’s a mix of regolith and ice or what other things you have to deal with will be certainly quite important But then, you know beyond those resources for the infrastructure the Thing we want to look at. This is not just something that will be useful early on it’s something that can expand out and allow you to Go from probably living out of the ships to begin with then building out habitation and landing pads and so on These these are things we’re having a very significant cargo mass and volume that that the bfr provides we believe will be quite helpful and Something where having that type of capability can also simplify the development that you’ll need to get going at the beginning So You know with that the idea would be to expand out you know, start off not just with an outpost but grow into a larger You know, base or, you know, really get to sort of something, you know, that that’s not just a base like there are in Antarctica but really, you know, a village or town growing into a city and then multiple cities on Mars So the types of capabilities that you’ll need there early on there’ll be things like resource extraction, getting surface power established Developing, you know, construction, you know, setting up landing pads habitats greenhouses and so on And then, you know, all the capabilities you’ll need to have a growing population on the surface, so You know, other, other things that will be necessary. Things like more additional life support both using local resources along with recycling And having things like surface mobility you can see here You know, a pressurized Rover but there’s also, you know, some people there on the surface operating You know, in surface suits, you know, beyond just a spacesuit but, you know, something that can work really well down on the surface another critical item to have moving forward with this And then, you know, there’s also questions just about what will, what will people be doing there? You know, what will they How will they be living and working? And we heard some about all the type of science The Rovers have been doing on Mars. Having the people there will really greatly expand, expand those Learn more about the history of Mars geology climate and so on and then really dive in You know, quite deeply, in some cases literally in, you know, in terms of going subsurface For looking at questions, like, you know, did life ever arise on Mars is there life there currently and so on So these types of things are really opportunities for, you know, pretty much anyone in the broader you know Mars related community to engage in. SpaceX is really focused on getting the transportation architecture set up and achieving that as quickly as we can. It’s really to enable all these types of activities there as well. So I’d certainly Encourage people who are able to contribute there to do so. So with that, I’m happy to take any questions Thank you Think we gonna have the mic come around or You know, just speak speak loudly and then I’ll That’s loud Um We’ve heard a lot this week about what SpaceX can do for us how is SpaceX benefiting from the work that the Mars Society is doing and What can we do further to contribute to what SpaceX is doing? Well, yeah, I mean the mars society as a whole Over the 20 years. I think it’s done a lot in terms of helping inspire people to you know Do what will be needed to get to Mars. As I said it’s been inspirational to me From a technical perspective. It’s always interesting to see all the different work that you know various people are doing to Help out with or determine various ways to do things on Mars. Certainly the all the analog work that the Mars Society Has done is also an area that can help inform What types of things you’d want to be doing while you’re on the surface? How you would operate in a remote Environment and with, you know, significant latency in terms of communication with Earth. There’s a lot of potential there Hi, yeah, I have a couple questions about the bfr spaceship first question is how long do you think eventually it will take to be able to turn that around and send it back to earth because I think Musk had originally announced that he would Have the plan of returning these spacecraft during the same synodic cycle So you can reuse it for the next launch window and my other question is Can you give us an update on how many tanker flights are needed to refill the BFS in orbit in order to get it on? Its way to Mars Alright, so yeah, the the overall approach with with these ships is, you know early on they’re very valuable on the surface of Mars so you likely would be actually having most most of the ships stay you’d be operating out of them using the various systems on them to for the activities there and then You know really extend your returning ships. It would be in the case that you’re bringing people back and Using them for those purposes. So yeah, very very much early on they’d be staying there, you know indefinitely As you move forward to further reduce the cost It is advantageous to be able to use those ships multiple times after Basically the value of bringing them back to earth and and flying them there exceeds the the value that they have on the surface So it’ll be something where that reuse interval think will and reuse fraction will shift over time But even more importantly just the full reuse here at Earth and doing things like the propellant transfer vastly reduces the cost versus trying to do this all in a single launch or in a more expendable fashion in terms of the number of tanker flights is really I Curved between the Delta V and payload that you’d want to have on that that there’s actually a whole slew of information up on our website at that will provide some information there and then the trade Becomes number of tanker flights versus amount of payload and how quickly you you want to travel there. I I may have missed this, but did you say or can you say how much mass? Can we get to the surface of Mars? I mean I know you just talked about payload versus fuel (right!) but what would be the mass capacity of one of these rockets to get? Cargo and people to Mars and can you compare that for reference? To say the Curiosity rover, which is the largest thing we’ve landed there. Sure yes, so the vehicle is being designed to deliver at least 100 tons of useful Payload, so that’s in addition to the ship and all of its systems to the surface of Mars. So, you know that’s in comparison to curiosity, which is around One ton You know, this this vehicle is really something that’s geared towards I’m not just you know doing science missions or even a small You know human human mission, but you know something that will enable, you know hundreds thousands and so on people to eventually get there Have heard they’re getting ready to start Doing some second stage testing at South Texas is wonder if there was any progress on those plans So we’re gonna have something that’s actually like a second stage or just a framework with some tanks and engines on it yes, overall the plan there is that we’re going to focus in on the the ship that second stage, get that going because that really is the critical item, having that fully reausable vehicle and we’re looking to do some hot testing it, you know it down in South Texas as you’re mentioning so similar to what we did as we were learning about Recovery on the first stage of Falcon we’re gonna do somewhat similar things and then build up our experience there with the ship Thank you for coming sir our government is currently looking at spending five billion a year to put in orbit around the moon a Station that will be used one month out of a year the spacex considered Testing the space worthiness of this by landing one on the moon and renting it out for maybe two billion a year. I Mean I think they’re there many capabilities this vehicle will offer, you know, whether it’s supporting on-orbit activities or activities on the surface of the moon Overall, I mean having a base on the surface would be quite quite valuable, you know It can be you know similar to what what stan done in antarctica having a you know permanent research capability there and then also enabling Opportunities for people to fly, you know to and from the moon Would certainly be interesting and the way we’re developing this system It’s something where we don’t need to, you know, choose either the moon or mars we can do both Okay, I think we’re out of time. Thank you

    So how many orbital ship refuelings via tanker will be needed to set off on a Mars mission?
    He said check the website… the website is no help.

    is it me or is Paul hard to understand? I mean phonetically. He does't seem to have some heavy accent yet I'm struggling here.

  • Peter Houle says:

    13:03 what happens when we get to Mars, as far as keeping people alive? "that's an area where people beyond SpaceX can contribute" = "that's not our problem"

  • Tabula Rasa says:

    So subtitles were edited, but cannot be posted?

  • James Karamath says:

    Last question was brilliant!

  • Pete Kuhns says:

    Six tankers to get this baby refueled for the Mars journey? Seven perfect performances including the mother ship with 31 engines each? That's 217 perfect full-thrust-duration engines. Gulp… surely SpaceX will experiment with a "simple" trip to the Moon first, right?

  • tobi foong says:

    To Paul Wooster, To get people to help build systems for a landed infrastructure .. we need interface specifications. Eg what is the maximum sizes for cargo units. Can someone send 100 tons in a complete unit(habitat)? probably not, how will it get off a landed cargo ship !! eg Most of the current 3d printed habitat machines being presented for the NASA challenges cant fit into the BFS Cargo or be safely extracted from the cargo area. So it would be good to have these specifications and methodology to disembark provided ASAP.

  • Nick Cullen says:

    Good Q at the end of renting out a landed BFS on the Moon to NASA at a discount compared to what they want to spend for a Lunar orbiting station.

  • Dumble Door says:

    Hmm, I had hoped for some more exiting news. This was a boring talk, filled with old information and old graphics 🙁

  • Bill Seidel says:

    There will always be the arm chair rocket /space travel naysayers, let them do so… When there's a successful Mars colony, they will be the most silent… until someone suggests colonizing a different world… Mar will be colonized.. It's inevitable.

  • edward murzin says:

    GO ELON! GO!!!

  • ann onn says:

    Astonishing; they can launch a car to Mars, but can't manage a decent microphone volume.

  • MrGlenspace says:

    Nice timeline however, like falcon heavy this BFR will also be delayed. 2022 and 2024 add 5-7 years minimum. Too many hurdles. As much as I love spacex and their enthusiasm, always add delays seen and unforeseen.

  • MrGlenspace says:

    Still way too many unanswered questions. If more than a few people how are they protected from radiation? How do you take care of the waste of many people. How do you take care of enough food? Do people have room to exercise and move around to stay in shape etc. these plans look good but way to many important details not even mentioned. To the moon it makes sense but Mars is going to be so tough. I see so many obstacles with this type of big vehicle to even mention for novice explorers.

  • MrGlenspace says:

    Something that tall could even tip over, than what? If achieved in actual time frame then this group should go down in history as legendary individuals.

  • Allan Brotchie says:

    need a better speaker, he is not so good.

  • Lake J22 says:

    I made it to 6:45 before I could no longer take his …um I guess um it was um his um stammer maybe um.

  • MaximumDistortion2 says:

    Is this the update elon was talking about on twitter?

  • MrGlenspace says:

    I know winds are very very weak. However, terrain might be overly rocky or prove unstable. Just saying so many variables that going to the moon is more important first learning step. Plus it woukd be nice upon the death of leading moon expert and proponent Paul spudis.

  • ADreviews76 says:

    still get boners from those two falcons landing

  • BAKERSMAN says:

    Too much time at work. Not enough time to go to Toastmasters meetings result in monotonal awkward speaking style that challenges the audience to focus on the subject as apposed to zoning out.  Very interested in the subject but there has to be a higher quality method of presentation than this.

  • leigh pierce says:

    Although the content of this presentation was interesting the speaker was quite uninspiring, boring with a flat voice – in my opinion. I could not bare to listern the whole way thru as he's voice irritated me.

  • David says:

    Nice Job, Paul. I don't think anyone could make something so exciting so boring.

  • Bo McGillacutty says:

    It will be fascinating for us watching from Earth but it's going to be hellish on Mars for quite some time to come IMO.

  • All My Hobbies says:

    who’s going to pay for all this pointless exploring.

  • Borce Ivanovski says:

    CO2 artificial decomposition is complete solution for life support environment to go and colonize the planet Mars #

  • Aurelius Tratos says:

    this es basicly the exact same speech that elon gave in australia last year.

  • Adam Wilkinson says:

    he was pretty coy about their lunar plans! …..bit of a sly smile too, wonder if theres a surprise coming??!!!

  • Zoutsteen from Holland says:

    100 metric tons. 1 ton is about 1 palette with 70 crates of 24 bottles of beer. … For those who need understandable size examples.
    From Earth to Mars takes about 150 days. So you've got 1120 bottles of beer to drink on your one way trip to Mars.
    Just saying: know your math! …

    And know you're allowed to trade metric tons for Air, Food, Equipment, Water.
    Just saying: Next to math, also know your science! … 😉

  • Franky Uk says:

    If you think rockets can work in space and fly to Mars, you do not understand Newton's 3rd law at all…

  • jeffrey exposito says:

    Once SpaceX lands the first astronauts in Mars I'm afraid the big tinfoil hat party will begin by all the haters and trolls who will claim that it is all fake and a Hollywood production. Jealousy has always bred contempt and hate and SpaceX is no exception.

  • Rob M says:

    SO the first crews will live inside the bfr on the surface for extended periods.. SInce building a habitat takes time.. This ,makes a lot of sense, except the massive doses of radiation they will be exposed to

  • taimer 86 says:

    uh..uh..uh…uh why is person speaking?

  • Lawrence Gatley says:

    So excited to see that space travel is being ignited again. I undrstand why the pause between the moon landing and now happened, and the reasearch done on the iss will be crucial for the next step, but man, this new adventure can't start soo enough!!!

  • SHOW MORE says:

    Proof that Al Gore was cloned

  • Til Merkan says:

    He really needs to get a grip about his "ahm"-Problem

  • R D says:

    1- There needs to be a user friendly web platform where people can see a list of the needs on Mars and required technologies, with information on whos working on it if any, progress, contact info/suggestions, etc. So we can have an overview, see what needs have no university/agency/company working on it, better coordinate and make collaboration easier. This could be an open source type of endeavor.

    2- In addition, the failure of Biosphere 2 demonstrates the absolute imperative to simulate a Mars colony in a sealed environment here on Earth to test and solve critical issues without needlessly jeopardizing the lives of people sent to Mars.

  • MrGlenspace says:

    Mesomeonenew the radiation problem can be overcome. So can the others. Yet to launch many expletive at once presents many more challenges. I did not even think about the CO2 problem from many people which would require having lots of scrubbers for a long journey. Yes BFR is exciting but a step to the moon first would be wise to work out the many bugs, and problems seen and unforeseen.

    A trip directly to mars is so far that a very small crew would make sense. Sending any huge team now that ends in fatality would be a very big blow to any future explorers. It would definitely cause a long pause in any program. Many people are risk averse and that is why the moon is logical first step to return and stay.

  • Heraklit N. says:

    No question about how they progressed so far with the bfr? I mean he clearly used the same pictures with the "2 Ships in 2022, and 4 in 2024" that musk did a year ago, but he never mentioned if they're still working on this timeline? I mean most of us believe THAT it is gonna happen, we just wanna know WHEN. We all also know the 2022/2024 plans are very optimistic, and already more than one year old, so an update on this would be great imo.

  • Nathan James says:

    I wonder what kind of testing will be done on landing on unpaved/rocky/unstable surfaces. I can just imagine the lander tipping over on Mars.
    Also, landing two craft near each-other could throw rocks, damaging the the already landed spacecraft.
    So many things to worry about!

  • Quinn Von Kerman says:

    Another benefit of Methalox is that it's cheap. Liquid methane is essentially LNG (Liquid Natural Gas), and LOX can be taken out of the air or water.

  • Gerg C says:

    They'll definitely be boring underground. The diameter of the BFR is perfect for transporting the drill.

  • Gerg C says:

    Its seeming like if a man or woman wants brilliant children, they should date and eventually marry a stutterer.


    Any order for the car from Mars yet?

  • MrGlenspace says:

    Apex, BFR will in no way shape or form be simpler than falcon heavy. It is a completely new vehicle with new challenges. Have they learned certain things, absolutely. I stress again getting to mars and back safely is very very tough.

  • replica says:

    Once it rains fish can survive Mars nature (waterlocks solves dust issues)

  • John Krug says:

    I can understand the enthusiasm for the BFR hardware…. To me though, it's a "must" to me that it be filled in with redundance and durability for the crews health, et al…. This first could be developed in Moon flights before going on to Mars….. As much as I'd like to wish for, unless there's a lot more resources provided up front, I don't think this can be assured in the suggested optimistic timeline of 4 to 6 years from now….. We'll see…

    Reading the comments- MAN YOU GUYS DON’T GET WHATS HAPPENING!!!! SpaceX is going to have 26 or more LAUNCHES THIS YEAR! There’s not a Country or private company that launches more than 6 per year. Next year SpaceX will do more launches than the rest of the world combined! If the BFR is successful SpaceX will be the gateway to Space and about 10-20yrs ahead of any competition! Paul is one of the brains that is behind SpaceX success!!! 🙂

  • Martin Zitter says:

    100t? What happened to 150t?

  • TheAtom says:

    Instead of wasting time & money & taking the risk of developing a propellant plant on the surface of mars, why not just send a BFR tanker ship & have it standing by in Mars orbit then just have the space tanker return for more fuel with the crew/cargo ship after refueling in Mars orbit? Seems like the least expensive & least risky method of returning a BFR crew/cargo ship. Although the BFR crew/cargo spaceship would need bigger fuel tanks to have some reserve take off fuel so it can meet up with the BFR tanker in Mars orbit.

    Why is no one talking about Aldrins Mars Conveyor. Also what about the lava tubes?

  • Robin says:

    Ya ya, the rockets are good, but humans CANNOT live comfortably on another planet, or even long-term space travel without gravity. You need to for example to launch in pairs and tether so as to fly through space like a bolo, to create gravitational effect as on earth. In tethered pairs you can live orbiting another planet and mine or replenish materials, but you CANNOT live on another planet's or moon's surface. Qualify my comment? I am just an ex-tech from Department of National Defence with a measured IQ of 144.

    There are no specifics here, no photos of new or completed launch hardware…this is just a rehash.

    Engineers should not give presentations…you know? Write the presentation, make the pretty pictorials, and then give it to someone who can speak in public without stumbling over the words. And when is SpaceX going to address the affects zero-G on passengers and crew during the 9 month journey to Mars? Mechanically, they've got their sh*t together. When it comes to human factors, not so much. Make the BFS capable to creating artificial gravity and many of the negative effects of zero-G can be ameliorated.

  • Damien Spectre says:

    Im curious – the month long dust storm on mars that effectively shut down the rover- is this latest martian "threat" being taken into account in plans to settle mars? i'm all for humans landing on mars by 2024 but kind of hoping we have backup plans on learnings from these (ie perhaps having to build backup storage that may last these dust storms if solar infrastructure fails during such super storms)

  • OldGamerNoob says:

    I wonder if the vacuum engines would end up being the most efficient ones to be used in martian ascent and descent with such low atmospheric pressure.

    That montage of the Falcon Heavy launch gave me goosebumps. Just to correct the host, the Tesla Roadster will not be out there until it disintegrates. It will be recovered and brought back to Earth (or perhaps Mars) one day to be put on display as a sacred artefact. Long live Elon Musk!

    No matter how much infrastructure you build, people will not go there unless there is some advantage to it, how will they make money? Artifacts, resources or freedom, those are the things that traditionally draw people.

    One thing they don't talk about for In Situ Resource Utilisation, specifically manufacturing propellant, is numbers. According to this reference ( generating 1 ton of fuel requires 17 MWh. To fully refuel a BFR requires 1100 tons of fuel.

    Assume you're only refuelling one BFR and are using the 16 month window between Earth Mars and Mars Earth Hohmann transfers. That's 480 days or 11520 hours, or 95 kg of propellants per hour. Call it 100kg to allow for (very low) handling and storage losses, and you still need a power input of 1.7 MW, or 170 10Kw Kilopower reactors at 226 kg each (38420 kg or 38.5 tons). The LANL Megapower reactor (35 to 45 tons, 2 MWe/5MWth) would work as well. The Sabatier reactor (based on scaling up the reference design) is another 5 tons.

    That's not including the mining equipment and or rovers you need to extract the needed water. Mini Excavators range between 2 and 8 tons. You need two for redundancy plus spare parts. So between 10 and 20 tons for mining equipment, though these will also be useful in setting up the installation as cranes or tractor units.

    Using worst case estimates, the total mass is 70 tons. So it could be done, but you're pretty much going to have to dedicate a Cargo BFR pretty much to ISRU components.
