Alternative Orion Missions Proposed

skywatcher2501 writes "Lockheed Martin, the company producing NASA's new Orion spacecraft, published three videos (news article in German) showing alternative Orion missions. Great efforts are made to show Orion's flexibility as a space transportation system beyond the goals of the Constellation program." The three videos, respectively, illustrate ISS missions with cargo in low-Earth orbit; autonomous use of the service module; and maintenance missions from low-earth orbit to geosynchronous orbit.

      Its a little more complicated than that. The reason you use a lot more fuel to get out of the atmosphere than you use once you make orbit, even on interplanetary missions, is that you've got to carry all that fuel with you out of the atmosphere.

      Spacecraft sizing is like a Russian nesting doll. If you required a 4:1 ratio of propellant to spacecraft mass to get to the moon, and you were able to reduce it to 2:1 propellant ratio, you could get away with about half the launch vehicle because you don't need to launch all that propellant. The equations defining this (Tsiolkovsky's rocket equation) are all exponential with Delta-V.

      Now as you can imagine, doing a return trip is even harder... imagine a Mars sample return mission. You have to have enough fuel in Martian orbit to get your sample and re-entry vehicle from there back to Earth. You have to have enough fuel on the surface to get that fuel and the sample into orbit. This means you have to send all of that fuel to the surface in the first place (requiring more for the entry burns), and of course this defines the amount of fuel required to leave Earth and get to Mars, which in turn defines the size of the initial launch vehicle. Minimizing one of the steps is enough to fit the mission onto a much smaller LV. This is why concepts like using ion engines, leaving return vehicles in orbit (like in Apollo), and extracting fuel from the target (ISRU) are so important, even though the amounts of propellant are small compared to the initial LV.

      Mission planning-wise, I wouldn't say that the two are very comparable either. An ion drive has a specific impulse of around 4000s, and something like VASMIR will give you 15000s (if I remember correctly, haven't looked in a long time).

    As I've mentioned in other comments, even if it isn't particularly sexy, I really believe the way you structure your procurement contracts makes a huge difference. From what I understand, most NASA procurement tends to be cost-plus monopolistic single-contractor contracts, where the cost-plus profit multiplier is just as high for development as it is for the actual product, so there's much less incentive to be efficient or finish the product early; I'm sure the engineers work just as hard regardless of what type of contract they're working under, but it makes a big impact on the way a project is managed. You also have to deal with substantially more red tape on a cost-plus contract.

    Things would be much improved by going for fixed-cost milestone-based contracts, sourced to multiple competing contractors. In that scenario management structures projects to be competitive and nimble, and if a company is underperforming, suffering overbloated costs, or not meeting its milestones, you just switch to one of its competitors. Of course, the problem is that you don't necessarily know beforehand which congressional district will be getting the funds, so that could make things more problematic from a political perspective (heck, just look at Sen. Shelby's opposition to diverting a miniscule fraction of some of the Constellation funding to COTS).
