SpaceX Intends To Send a Red Dragon To Mars As Early As 2018 (blastingnews.com) 119

Reader MarkWhittington writes: SpaceX has announced that it intends to send a version of its Dragon spacecraft, called "Red Dragon," to Mars as early as 2018. The mission, to be launched on top of a Falcon Heavy rocket, would be the first to another planet conducted by a commercial enterprise. The flight of the Red Dragon would be the beginning of SpaceX CEO Elon Musk's long-term dream of building a settlement on Mars.Ars Technica reports: According to the company, these initial test missions will help demonstrate the technologies needed to land large payloads propulsively on Mars. This series of missions, to be launched on the company's not-yet-completed Falcon Heavy rocket, will provide key data for SpaceX as the company develops an overall plan to send humans to the Red Planet to colonize Mars. One of the biggest challenges in landing on Mars is the fact that its atmosphere is so thin it provides little braking capacity. To land the 900kg Curiosity rover on Mars, NASA had to devise the complicated sky crane system that led to its "Seven Minutes of Terror." A Dragon would weigh much more, perhaps about 6,000kg. To solve this problem, SpaceX plans to use an upgraded spacecraft, a Dragon2 powered by eight SuperDraco engines, to land using propulsion.

    So they're pretty much guaranteed to meet their goal.
  • forget delays, forget budget overruns, forget subsidies, forget failures, forget others, just focus on hype and dreams!

    at this rate musk will land on mars using hype alone. and fanboys will take that for the real thing.

      and fanboys will take that for the real thing.

      also note if you post something critical of SpaceX, they will flame your butt. One person who continually posted critical remarks (or negative as some saw it) about the New Space crowd in many space forums and was banned from all of them except one (comments in Spudis lunar blog). He had reasons, whether people agreed or not but he did raise some interesting points such as if going beyond earth orbit need LH2/LOX and also raised caution of Ayd Rand policies for space programs.

        Sounds like there was a good justification for the flaming. I've run into people who care about the danger that there might be libertarians or objectivists in space. These people are to a man dumb.

        Why should we worry more about libertarians in space than progressives in space? Well, aside from the former being more likely to be in space? Har har har.

        Also, a lot of the criticism of New Space, SpaceX, and similar topics is rather dumb (you might see a theme here). I don't admire the ability to ignore 60

    I think he is off to a good start. Don't know about the time table. He has successfully shown that he can perform this type of lift and landing. He's not demonstrated reliability just yet, but he has been successful and this looks to be the beginning of a pattern. He has shown that he can perform second stage upper orbit capabilities so this one should just require the larger rocket. It's a little behind schedule, but barring any major setbacks, he and his crew should be able to perform a limited landing in the near future. Less than two years? Hopeful but not optimistic.

      The Falcon Heavy hasn't flown, he's never been beyond LEO (the difference in thermal environment is of particular concern here), and no Dragon of any kind has ever landed propulsively. (Though there have been some short test hops IIRC.) Or, to put it another way, pretty much none of the precursors to this mission have been demonstrated, let alone

        Seriously, are Musk fanboys just completely clueless when it come to space technology, or are their blinders that thick?

        I guess you missed SpaceX landing the Stage 1 boosters on land (Florida) and at sea recently after accomplishing their missions, in both cases using propulsion. Expanding that for the additional stages should actually be an *easier* task than what they've already done.

        • Landing the second stage will be the most difficult because it will be traveling at orbital speed.

            Not really that big of an issue compared to what comes after the slow down.

          You're the second clueless fuckwit with the reading comprehension of used bubble gum that doesn't seem to grasp that a Dragon isn't a Falcon, and Mars isn't Earth.

          • Landing Dragon should be *WAY* easier than landing a Falcon 9 first stage. You're coming in from higher and faster, but you have a heat shield, parachutes, redundant engines designed to operate at the scale of a landing craft (rather than a first-stage booster), far more structural integrity than a booster with depressurized tanks, no bending moment to speak of, engines places around your center of mass rather than at a single point below it, throttle capability sufficient to hover at least in Earth gravity

            As cbhacking kindly pointed out, those are not as big an issue. SpaceX has already demonstrated hovering capabilities (see videos for the Falcon9 for their testing - with propulsive take-off and subsequent landing on Earth). Yes, they may not be slowing down from orbital velocity, but that's not a huge issue - a far bigger issue is what to do when you slow down enough and get close enough to the ground that you have to deal with both (a) slow movement and (b) time to impact - SpaceX has demonstrated knowled

        Who is "he"? As far as I know Musk hasn't been in space at all, I don't know if Dragon has ever been outside LEO but SpaceX have delivered several satellites to GEO and one to L1, so certainly the rockets can reach Mars. And he hasn't landed a Dragon propulsively, but a huge shell of a rocket with wind or waves to deal with actually seems harder than Mars, except you don't get a paved landing pad. Isn't that more similar to what NASA did in the 60s than what SpaceX did just recently? That said I do expect a

    • SpaceX will be the first entity to place humans on Mars.

      And even after that upset is in the history books, there will still be some people who cling to the fantasy that government does things more efficiently than private enterprise.

  • It's much warmer there, and with all that energy and thick atmosphere, there is a lot more to work with. It is comparatively alive compared to Mars.

    • It's also far more hostile to equipment, and there's zero chance of a manned mission there in any foreseeable future. Mars has potential for human habitation. Venus does not.

      • That hostility has to be exploited, not avoided. It's free energy. And all those chemicals, what couldn't DuPont and Monsanto do with them? Fertilizers and catalysts galore! A hot tasty primordial soup just waiting to be served. I believe the Genesis Project has a much better chance on Venus, and would ultimately require much less human effort.

        • Oh god, that is literally the entire plot to the first 2/3 of The Expanse series.

        • The problem with Venus, as with Mars, is the lack of a decent magnetosphere. Earth's magnetosphere is it's "Secret Sauce." It's difficult to get a decent biome going when every medium-sized gamma burst from the sun bombards the planet's surface. You could build lead-lined underground bunkers and grow everything using redirected light from sonotubes, but then you might as well just colonize the moon.

          • Yeah, the moon should be first choice anyway as a base camp for building, testing and launching the long distance stuff. I don't understand the lack of interest in that phase. Along with the food and water, you just gotta get or build a smelter up there and mechanize the process as much as possible. Easy, right? A lot easier than doing it on Mars, that's for sure. You don't need extra lead for the radiation, a thick layer of moon dirt is sufficient.

      • Actually the upper bounds of the atmosphere on Venus is relatively habitable. The catch is you need a floating structure that can maintain a certain height from the ground for long periods of time (potentially decades or more). It's the lower levels of Venus which would require serious effort to manage do to pressure, temperature, and atmospheric content. This by the way is why you can google Aerostats.

        Btw: https://en.wikipedia.org/wiki/... [wikipedia.org]

    • The only problem is that out of control capitalism and the Venusian Oil Cartel has led to a runaway global warming on Venus, the locals there screwed the planet up before we could get to it. They should have used Solar Power, I hear it was quite efficient there. ;)

  • I really hope this is a success, this would demonstrate the viability of the private industry moving humanity into space. We as a race need to see this happen.

  • I wonder how many impact craters he will create until he gets one right?
    • In engineering progress, if you're not breaking something, you're not pushing against the limits hard enough. This is kinda the opposite the mentality of 'failure is not an option'.
  • Seriously, once the first one goes, it should be possible to land 2-4 tonnes on Mars. And with it being enclosed, it should be easy to control the HVAC for various instruments. The real problem is, how to get things out of there. Probes. Landers. Etc.
    Regardless, if SpaceX is successful, which I would be shocked if they are not, then it will dramatically change how we study Mars.
    Best of all, this will costs a fraction of what the other missions have costs. Heck, we should be able to send a red dragon AND
  • One thing good about the dragon heavy is the capacity. The best thing they could do is maximize every launch by taking more raw resources into space and leaving them up there in storage. Imagine if they created storage depots both in front of and behind space stations. That would minimize risk to manned space stations due to space garbage.

    We seriously need to build fuel storage depots up there along with junkyards where metal can be recycled so we can start building in space.

    Are we privy to a great becoming?
  • The missing ingredient here is a sponsor. Having said that, this could be a pretty cheap mission as these things go. NASA would be nice, but the cost would be low enough for various private industry or research groups to be involved. Perhaps several could band together and split the costs.

    Since Red Dragons are Chaotic Evil, it seems that they might lose control of it. They should send a Gold Dragon instead, since they're Lawful Good.

  • I've speculated before on /. about how much effort/cost it would be for SpaceX to do a manned moon mission.

    If they can do this Mars mission (landing on Mars but not returning), exactly the same hardware can do a lunar landing and return. From here [wikipedia.org] we see for Mars mission:
    Delta-v LEO to Mars transfer typical value 4.3 km/s
    Transfer orbit to Mars capture orbit 0.9 km/s
    Capture orbit to low orbit 1.4 km/s
    Low orbit to surface 4.1 km/s
    Total delta-v from LEO: 10.7 km/s

    Lunar mission:
    LEO to low lunar orbit: 1.3 km/s

    • Oops, some 'less than' signs got eaten by HTML.
      LLO to Earth intercept: < 1.3km/s (then you can aerobrake and re-enter)
      Total delta-v from LEO: < 6.4 km/s

  • This mission seems very hard to justify from a commercial view point.

    Wikipedia [wikipedia.org] says
    "As of May 2012, SpaceX had operated on total funding of approximately $1 billion in its first ten years of operation. Of this, private equity provided about $200M, with Musk investing approximately $100M and other investors having put in about $100M."

    So (as of four years ago) Musk only owns about 50% of SpaceX, so it isn't his plaything to do with as he wishes. How is this squared with the other investors?

      I don't know the exact percentage of share ownership in SpaceX, but my understanding is that Musk owns a lot more than 50% of it and can pretty much call the shots. Just because the investors put in the same amount of money doesn't mean they got the same amount of equity as he did.

      Musk has been quoted more than once saying how much harder it would be to run a company where he was answerable to shareholders.

      In any case, he has been open about his goal of getting to Mars even since before he started SpaceX, s
