First Images of Russian-European Manned Spacecraft 191

oliderid writes "The first official image of a Russian-European manned spacecraft has been unveiled. It is designed to replace the Soyuz vehicle currently in use by Russia and will allow Europe to participate directly in crew transportation.The reusable ship was conceived to carry four people towards the Moon, rivaling the US Ares/Orion system. This project is the Plan A for the European Space agency. The plan B is an evolution of the ATV proposed by a consortium of European companies led by Astrium."

        You could never, ever see the Apollo flags on the moon through a telescope. Partly it's because they are very, very small. But, mostly it's because they were not left behind. What is left behind on the moon are the LEM descent modules, plus miscellaneous equipment like those rover buggies from the later missions. Those are still too small to be seen from a telescope. However, once the Lunar Reconnaissance Orbiter launches later this year, it's LROC camera (a close cousin of the HIRISE camera on the Mars Reconnaissance Orbiter) should be able to see evidence of the Apollo missions.

        Indeed. I always thought space elevators seemed so fantastic as to be beyond belief but damned if that might become practical before the seemingly less-challenging Buck Rogers rockets.

        I always liked the idea for the old Orion drive ships. "We're not going to be building these things like dainty tinfoil creations, they'll be welded together in drydocks like navy destroyers and weigh about as much. Float 'em out to see, light off the a-bombs, they can handle the weight." Now I don't think even Dick Cheney could go along with the idea of a bomb-powered ship but I wonder if anti-matter would be a suitable replacement charge? Aside from the issue of not being able to manufacture it in any sort of significant quantity, I'm wondering how bad the gamma flashes would be. Would it be safe if we towed launch vehicles out in the middle of the ocean? How much ocean water would it take to block the rays? Would there be any ionizing radiation to produce fallout?

        I've heard some other crazy ideas for non-chemical rockets. One design has pellets of deuterium dropped into a chamber where they are precisely hit by multiple lasers and causes a tiny fusion explosion that is forced out the bottom of the ship, giving a far better bang for the buck than conventional propellants.

        It just seems like we're rehashing the way things were done before instead of coming up with something new. Is it that the technology is so bleedin' difficult to invent, is it a lack of money and political will, or would the danger of the technology be so great that there's no way in hell anyone would sign off on it? I mean, we could have built Orion in the 50's, we could crash-build one of those things in the event of some planetary emergency (i.e. needing to get Bruce Willis up to an asteroid to blow up), but nothing short of that would convince people to use nukes for go-juice.

              The blast is deceptive, it is generated by the released gamma radiation being absorbed by surrounding matter rather than by the contents of the bomb absorbing energy. On Earth nuclear explosions have a big blast because their is plenty of atmosphere to absorb the gamma, radiate less energetic photons, and expand, a nuclear burst in the water is much less effective blast-wise than an airburst and a in-ground blast is down-right disappointing. In space there is no practically atmosphere so there is little to expand due to the energy release except for the ablative coatings in the engines themselves. Eventually we'll be pushing asteroids around by detonating nuc's near them which will vaporize the surface facing the release and generating the expanding reaction mass.

            Obviously, you have never designed a rocket. Fortunately I have!

            Here are the real equations:

            delta-v = 9.8 * Isp * ln(launch_mass/orbit_mass)

            delta-v to orbit is about 9000 m/s

            Isp is an engine parameter. Simple Lox/Kerosene engines come in around 350s, complex lox/hydrogen engines come in around 450s. (Rocket engines do not run stochiometric, they run fuel rich - the reasons are complex, but essentially hydrogen is better at converting heat into thrust than water.)

            OK, so let's do some numbers:

            9000 = 9.8 * 350 * ln(launch_mass/orbit_mass)

            ln(launch_mass/orbit_mass) = 2.62
            launch_mass/orbit_mass = 14

            So you need 14 pounds of propellant for every pound of orbited mass. of that 14 pounds of propellant, about 3/4 are LOX - which is essentially free (pennies per pound in large quantities). So really you are paying for 10 pounds of kerosene, about $5 or so.

            Now, for real rockets it ends up closer to $20 per pound, because 1) rockets tend to use more expensive liquid hydrogen, and 2) rockets stage, which is slightly fuel inefficient.

            But my original numbers are correct. Yours are wrong - or at least misrepresented. 5.5 kg of propellant, 3/4 of which is LOX would not get you to orbit, but would cost about $1.

          The electric potentials on Earth often get pretty extreme during an electrical storm and carbon nanotube are conductive. I've seen videos of carbon nanotubes exploding when irradiated with a flash of light, that's a bad combination! If they shoot rockets [wikipedia.org] into the sky to bring down lightening trailing a thin conductive wire or even a conductive contrail [wikipedia.org] imagine what something massive like a space elevator cable will do!

        There's just no way to cheaply lift payload to orbit using our current rockets.

        Sure there is. High launch frequency and reusable vehicles. Rocket propellant isn't expensive.

    • We've been at it for decades and the latest and greatest the Ruskies and Americans come up with looks like pretty much the same shit we've been doing for years

      I wouldn't expect it to look like anything else. Like airliners or submarines the design is driven mainly by aerodynamics (hydrodynamics) and engineering constraints, not by the need to 'look' different in order to be fashionable or meet the expectations of someone who expects it to look.. I don't know, modern? Science fiction-y?

    • Actually, I think it bears an uncanny resemblance to E.V.E. [google.com]

    • If it ain't broke, don't fix it. As long as we are stuck using chemical rockets launched from the Earth's surface the basic capsule design works.

    The choice of words "towards the moon" is very well done. Article states this is capable of bring six people into Terran orbit, and four into Lunar orbit. I understand the difficulty in getting down to the moon and back up, but if you're capable of getting there and back with four people, odds are you can get down to the surface. Why not just go for broke? At the very least it'd be a huge PR coup.

      Not a bit of it. It's a question of fuel.

      Having reached the Moon, you have to fire engines to slow down into orbit. Otherwise you loop around the back and head straight back to Earth like Apollo 13. So you need to carry fuel for this.

      So now you're circling the Moon like Apollo 8. Good. To come home, you need to fire engines again to speed back up. More fuel.

      But wait, you want to visit the surface? Then you need a lander. Those things are heavy. And it needs fuel: fuel to land, and fuel to take off again.

      That's the trouble with spaceflight. It's all about fuel. Every manoeuvre burns fuel. Every kilogram of fuel means you need even more fuel at the start, just to carry that fuel into space with you. It's why the Saturn V rocket was the size of a skyscraper, but only carried something the size of a minibus to the moon, and brought only a tiny capsule home to Earth. All the rest? Fuel tanks.

      • It's why the Saturn V rocket was the size of a skyscraper, but only carried something the size of a minibus to the moon, and brought only a tiny capsule home to Earth.

        As you so correctly state, fuel is the key. Except, the Saturn V only got them to the moon. Getting into orbit, landing, coming back up, and getting back to earth was the job of your minibus and tiny capsule. Clearly, it is quite possible to pull off the whole shebang by throwing a huge rocket at the back of it to get it off the planet (by far the hardest part). Using a system like the Saturn V or current boosters is by no means a far reach for them. It sure as hell wouldn't be easy, but if they're a

          Saturn V got Apollo to the Moon, with the fuel and equipment necessary to stop and land there and to come home again.

          Let's see: the service module, the lunar excursion module, all the fuel for both of them... that's got to be three or four times the mass of the command module, which was all that got back to Earth (I haven't looked it up so this is probably well off). A rocket whose sole purpose was to send a crew around the Moon, but not to land, could have been a whole lot smaller than Saturn V.

          Look at it this way: suppose that bringing along a lander and fuel supplies for a Moon landing doubles the mass of your spacecraft at the Moon. Then clearly, that must require that you at least double the size of the rocket on the pad.

          I don't actually know what the plan would be for a Moon landing with this vehicle. The fact that it has its own thrusters for landing suggests to me that it might have a direct-ascent mission profile: no separate lander, just bring down the whole ship. NASA considered this approach when planning Apollo: it has the benefit of simplicity, but would have needed a more powerful rocket even than Saturn V to bring enough fuel. Perhaps with modern materials and engineering it could be done this way: but as the article says, no rocket powerful enough currently exists.

          • by Urkki ( 668283 )

            Alternative: have ability to refuel on orbit, so you can send the fuel with separate rocket or two, and fuel the landing capsule on lunar orbit (probably twice, once for landing and takeoff from the Moon, second time for the trip home).

            Then you can cope with much smaller rockets. But of course refueling in lunar orbit is probably quite a complicated operation, and fatal if something goes wrong, and might be very hard with some rocket fuels... I guess all these complications are why it wasn't done with Apoll

            • Yeah, that's definitely the ticket. I think what you actually want to have is sufficient fuel to make it to lunar orbit and back again, so if anything goes wrong with the refueling, you're not stranded. Other possibilities include refueling in LEO, at the space station, say; since getting to orbit at all is by far the biggest fuel cost, this could work pretty well.

              Of course, at that point you're talking about establishing infrastructure in lunar orbit, so the next step is to establish infrastructure on

    I'm not sure I'd be too happy if I was being put in that, the booster landing thing sounds like its asking for trouble if you get low on fuel, or they get knocked out of alignment or a floating point error messes up their servo controllers....

    At least with a parachute or wings you know that so long as they are they they will work. Also I imagine that it will require a huge amount of fuel to turn it around and then slow it.

    Or have I got the wrong idea and they're going to parachute in and then just use these at the end at which point again you have to ask - why bother?

    Why land on a planet with a thick atnosphere like earth using thrusters causing you to have to waste spcae and launch weight on alot of propelant. I understand that this thing is also meant to land on the moon so requires some landing thrusters (no atnosphere) but the moon has a mere fraction of the earths gravitic attraction and so if the capsuale use parachutes aswell as thrusters there would still be a weight saving. Even probes that land on mars usualy use parachutes aswell as thrusters even though it
    • Almost certainly, they are thinking mars and the moon. But I consider this a backwards step. It seems that all of the initial steps should be specialized rather than generalized in the same fashion that the shuttle was. The Orion and Dragon are highly specialized. I suspect that we will see other countries heading in the right direction, by specializing rather than making it the end-all.

    The reusable ship was conceived to carry four people towards the Moon

    Apparently the ESA / Russia are ushering in a new age of "close enough" space exploration.

    News Report, 2021:Today astronauts from the ESA will begin a new chapter of space exploration by first going up really high, and then kinda drifting off in sort of a that way direction. The mission captain was interviewed recently concerning the importance of today's historic flight.

    "We are confident that the up portion of the mission will go smoothly. We then plan to transfer to the next stage where, God willing, we will be the among the first humans to end up somewhere over toward the Moon." He commented, waving vaguely off toward the sky.
