SpaceX Shows Off 7-Man Dragon V2 Capsule 140

Posted by timothy from the yes-please dept.
As promised, SpaceX has unveiled its design for a 7-passenger space capsule, intended for carrying astronauts to the International Station or other missions. Writes the L.A. Times: "SpaceX's Dragon V2 spacecraft looks like a sleek, modern-day version of the Apollo capsules that astronauts used in trips to the moon in the 1960s. Those capsules splashed down in the ocean and couldn't be reused. SpaceX builds its Dragon capsules and Falcon 9 rockets in a vast complex in Hawthorne, where fuselage sections for Boeing's 747 jumbo jets once were built. The company is expanding its complex, near Los Angeles International Airport, and has more than 3,000 employees."

NBC News offers more pictures and description of what conditions aboard the Dragon would be like, while astronaut Chris Hadfield says that for all its good points, the Dragon won't eliminate the need for international cooperation in space: "The United States cannot fly to the Space Station without Russia, and Russia can't fly to the Space Station without the United States. It's a wonderful thing to have. If you look at the whole life of the Space Station, think of all the tumult, with the fall of the Soviet Union, and the devaluation of the Ruble in 1998, and other countries backing out of it, the Columbia accident, which would have left us completely helpless if we hadn't had the international commitment. It's easy to have a one-month attention span, but that's just not how you build spaceships, or how you explore the rest of the universe."

        Just one point about the summary, not just the 1960s, there were more trips to the moon using Apollo in the 1970s than in the 1960s:
        1960s Apollo moon trips: 8, 10, 11, 12 (2 landings 11, 12, and 2 circumnavigations)

        1970s: 13, 14, 15, 16,17 (4 landings, not Apollo 13 obviously)

          You also can't ignore the Skylab 2, 3, & 4 missions that all used Apollo hardware as well as the Apollo-Soyuz Test Project (something that arguably paved the way for the ISS in terms of cooperation between the Soviet Space Agency and NASA). All of those missions also flew in the 1970's.

          It is a pity that the manned mission to Venus never happened, which was also supposed to use Apollo hardware and something very similar to Skylab for extended mission resources. It could have happened for the price of a single shuttle mission too.

      Maybe the small matter of getting the thing into space using a rocket engine is why they still need the Russians.

      The most powerful rocket engines are made by the Russians... and the US buys several a year to launch its biggest payloads into space (http://www.washingtonpost.com/national/health-science/us-military-national-security-agencies-vexed-by-dependence-on-russian-rocket-engines/2014/05/30/19822e40-e6c0-11e3-8f90-73e071f3d637_story.html)

      SpaceX is developing some pretty powerful launchers, but until they can match the power and reliability of the Russian RD-180, I don't think that NASA or the Pentagon (who are the biggest buyers of the RD-180) will be turning their backs on Russian engines.

      From the linked article: "Long-term U.S. plans to produce a domestic cousin to the RD-180 never got off the ground. The aerospace sector discovered that it was comfortable with the workhorse Russian engines when it came time to launch sensitive missions like spy satellites. The Atlas V rocket has made more than 50 consecutive successful launches using the RD-180. NASA and other government agencies rely on the Atlas V for some of their scientific payloads."

      I have no doubt that the Dragon capsule will live up to its billing... So far, Elon Musk and SpaceX exceeded expectations on virtually everything. But, until then, the rickety, but dependable Russian Soyuz will continue to be the preferred choice of most astronauts for getting to and from the space station.

      However, the real reasons that astronauts like Chris Hadfield et al think that the Russian Soyuz will be hard to replace are hard to fit into a single post.

      • Consider, for instance, that the Soyuz TMA-M can hang around the space station for 6 months, and be ready for use to return astronauts safely back to Earth, without a maintenance crew having to go and check every nut and bolt - a feat that even the Space Shuttle could never muster (for the record, the Space Shuttle had a mission duration of about 12 days - a few Columbia missions went up to 16/17 days).
      • Another example is that it takes the Soyuz just 6 hours to go from launch to docking with the space station (for comparison, it took the space shuttle almost 3 days to reach the space station after launch).
      • There are many other little things like these that are not cool or sexy, but make the ruthless efficiency and effectiveness with which the Soyuz executes and fulfils its purpose is second to none. It will take a lot more than a larger tin-can and a more comfortable ride to convince astronauts to put their lives in SpaceX's hands.

        OK, keep in mind orbital parameters. The ISS's orbit was specifically placed the way it was to allow the Russians to get to it with ease. It's on a steep incline that takes orbital corrections to manuver to from any other launch site than Baikanour. It passes directly over Canaveral occasionally, but the delta-v required to do a one shot insertion orbit to ISS from Canaveral is expensive. That's why the Shuttle was downrated for ISS missions in payload and duration.

        Shuttle was also a hell of a lot more complicated than a Soyuz capsule. It's like comparing a Prius to a Model T. Soyuz was designed for no-frills get them to orbit. Shuttle was designed to get a shitpile of cargo to orbit along with the crew and the gear to operate independently of anything once there. Think of it more like a spacegoing Winnebago.

        • How hard would it be to move the ISS? It's obviously not going to endure any great acceleration, but it needs to occasionally accelerate to adjust for atmospheric drag anyway. Just reangle those and nudge it a little each time. You wouldn't want to take it all the way equatorial, but enough to reduce the requirements from somewhere more southerly.

        That's a human consumables issue. Nobody is living in those Soyuz during that time.
        They never tried something like this with the Shuttle, but just docking an empty one for

            That was MY point.

            But there was no justification in keeping the shuttle. Cancelling it was a wise and prudent decision, probably the best decision in the space program since 1969. Just for reference, all of SpaceX's achievements to date have been done with less money than a single shuttle launch.

            Cancelling it WHEN THERE WAS A REPLACEMENT AVAILABLE would have been a wise decision. Cancelling it before a replacement was just plain stupid. Now... don't get me wrong here: yes, it was old and worn out and too expensive. My point wasn't that it didn't need to be cancelled, but that a replacement should have been designed and flying before then.

Too costly and risky. 2) Pour money into private companies to do the same. The public would never go for it, and it would also be too risky. 3) Cancel the shuttle program and divert the leftover funds to private companies to design a new manned vehicle, and in the meanwhile send up astronauts (as part of ISS obligations) with Russian rockets.

      Escape sequence test later this year groundside.

      At least one more of those from atop a Falcon in flight,

      After that, they can put men it for further testing groundside (pretty much more escape sequence testing).

      Then they send some men up in the thing.

      Note that in parallel with that testing, there'll probably be at least one unmanned test to the ISS to test whether this thing can dock to ISS without the robot arm.

      After all that, it goes live. Note that Dragon V2 is expected to be man-rated by 2016, if you're trying to guesstimate how long any testing will take. Note further that "man-rated" does not necessarily mean "ready to dock with ISS"....

      • Want to bet on whether or not SpaceX convinces NASA to let them transition to sending up the DragonV2 on the supply runs as part of the testing? It would give the new capsule valuable flight data, and wouldn't cost NASA another cent contract wise.

          They're not really interchangeable. I'm pretty sure the berthing port is larger than the manned docking port, so that would limit the size of pressurized cargo because of the smaller door.

          Probably already in the pipeline for when they need to start testing the capsule in space. Unmanned cargo launches to see what it does, then go for the meatshots.

        • They have to alter the docking ring, something that's scheduled to happen later this year. That hardware will, IIRC, go up in one of the upcoming Dragon CRS flights. It's not needed for just the Dragon, either. Orion and all of the other capsules under development will also use it.

      • Awesome. I've been wondering about these details. You work for SpaceX or something?

      That's what incremental tests are for. Like the legs they tested out on the latest Falcon launch.

    Hadfield: "The United States cannot fly to the Space Station without Russia, and Russia can't fly to the Space Station without the United States."

    Really means: "As a starry-eyed utopist, I don't WANT the United States to be able to fly to the Space Station without Russia, and I don't WANT Russia to be able to fly to the Space Station without the United States."

    Why stop there, Hadfield? Why not make it impossible to do without the cooperation of China, India, Africa, South America and the other 90+% of the world, too? Because it doesn't just take a village; it takes a whole world to do anything.

    Poppycock. Russia doesn't need the US to enable it to do a damn thing. And if/once the US gets its head out of its ass, it won't be abjectly dependent on Russia either. And the EU is there too, albeit not manned capability yet, and China and India are coming along rapidly too. And that is a good thing. The less you depend on a single gigantic tower of babel to accomplish everything, the better. That doesn't mean a desire for conflict. It means a desire for a rich flowering variety of innovating independent enterprises, because that is how you get redundancy.

    The star trek universe of a brotherhood of peoples is a siren song of what we (some of us) believe can be, and want to be, But man, it is not held together by everyone believing they NEED everyone else to accomplish anything. It is held together by everyone WANTING to collaborate with everyone else to mutual benefit. The Earth guys still have their own starship design, as do the Klingons, the Cardassians, and yes, even the Ferengi and the Romulans. The only way you can get into the brotherhood is to first prove you're good enough to Do Stuff yourself.

    • Chris Hadfield is a Canadian. Of course he wants international cooperation, otherwise, how is any non-US or non-Russian governmental astronaut/cosmonaut supposed to hitch a ride up and get a berth in orbit?

        You're kidding, right?

        At the moment, Canada pays the US to pay the Russians to get us into orbit. In a couple years we'll pay the US to pay SpaceX to get us into orbit, or we'll just pay SpaceX directly, and save a bundle in the process. It doesn't make bit of difference to us whether or not the US and Russia are cooperating.

        Hadfield's pro-international-cooperation stance is purely a result of his own values and politics. Though I have a hunch most astronauts would voice similar feelings.

      No as a realist. If we wanted anything in the US to do the job well enough to reject the Russian's help NOW we would have had to put some effort in back from when Clinton was President. Since there is no other serious choice for a few years there's no option other than to accept reality, pay for seats on Soyuz, and give companies like SpaceX some help for a few years until they become a serious contender.

          No.
          Which is why there is an international effort that includes sites in the southern hemisphere as well.

                The only obvious error I see on my part is in overestimating the height of the ISS, which would on closer examination pose more of an issue for the inclined orbit. But this doesn't explain why i

                  One word you can already relate to - lag.
                  There are a variety of other issues that make it far less desirable than ground stations such as bandwith, directional antenna placement and it being a hell of a lot easier to put hardware on solid rock than orbit.

    • What? Believing that interdependence is good doesn't mean that you are a bleeding-heart one-love hippy. It just means that Hadfield is a realist and acknowledges all the expertise and capability of the Russians. And that he understands the fact that the ISS literally cannot survive without the Russian modules that perform critical functions.

      I'm not saying that scrapping our manned space capability before we had a replacement was a good idea, nor was it a good idea to design our workhorse military launch
