They would not need to borrow a lot of money until they are ready to fly test missions (which would be when the big bucks start to be spent fairly rapidly), and by then they would presumably have sufficiently established their technical, commercial and financial viability to the banks that they should be able to secure any loans they might need.

See? So if they went bankrupt on a $7.5B loan, the bank could have the gold reserve for half a cent on the dollar.
If the falcon heavy can send a red dragon to mars and land one tonne on the surface, why can't it send a dragon on a lunar flyby?It is stated in the Aaia paper that a small propulsion module would be needed. Is this because the authors of the paper discounted the performance by 10%?
This if true bothers me because it indicates a non-inhouse integrator company that hires other companies to do all the development and hardware manufacture. There are inherint costs increases to hiring out of ~30% more in costs. So if this is an indication of thier business structure it has some significant managerial and contracting challenges.In other words this would be like a NASA surrogate organization streamlined for a narrow focus and goal. It would not represent the cheapest this could be done for with a new space policy of "we do the concept and build the hardware ourselves" vs an old space policy of "we do the concept someone else buids the hardware".

Even if they removed the crew and replaced it with samples.No, it's actually not. Moonrise was a JPL proposed New Frontiers-class mission at about $1 billion, and would only have returned 1 kg of lunar material. And that would have been a random grab sample of gravel wherever it happened to land. Hand-collected samples of interest are much more valuable, which why certain Apollo samples are much more in demand than the rarer Soviet Luna samples.$1.5 billion for 50 kg of samples and the deployment of a surface station (Stern's "GoLDSTP") is a bargain compared to what JPL would charge to do it robotically.http://www.planetaryprobe.eu/IPPW7/proceedings/IPPW7%20Proceedings/Presentations/Session7B/pr516.pdf

This was the approach taken by Kistler, with their contractors eating their lunch (launch :-). If I had $1.4B lying around, I wouldn't pay another company to launch me to the Moon. I would start my own company, SpaceX style, and hire engineers to design and construct the needed elements. The carrot of working on a Lunar landing program would induce a lot of good engineers to come work for you (including pinching a lot of engineers from existing aerospace companies). This means I won't pay $100M for Lunar spacesuits and systems. I would pay $10M or less for suits and systems we made ourselves.

That is exactly how to do it.The launchers are expected to exist by the time they plan on launching, so no need to design that part. However they should look into designing their own lander ( could buy off the shelf parts for it ).
The transfer stage will either require a modified Centaur or a clean sheet cryo LOX + either LH2 or LNG. I think single-engine Centaurs can be adapted for about $200M, requiring mainly a tank stretch or the add-on tank that has been discussed. You'd have to make sure that LM didn't overcharge for the modifications, and that would be tricky. (AFAIK, LM/CLS and not ULA would have to provide the Centaurs, since ULA can only sell to the gov't, not to commercial firms.)
If you stick with storables for the lander, I am certain it can be done for < $300M.
Quote from: HMXHMX on 12/09/2012 03:59 amIf you stick with storables for the lander, I am certain it can be done for < $300M.And that also gives you the option to refuel, which takes care of all launch vehicle and transfer stage size issues, ....
The propellant combination used in the fully storable lander studies (conducted by lead author James French) was constrained to use earth‐storable propellants (for operational simplicity) and to use existing propulsion hardware that could be adapted with minimum development. After looking at a variety of options, the concepts which produced a viable result were twostagevehicles using a lander stage and an ascent stage. Each stage used a solid propellant rocket motor supplemented by liquid propellant rocket engines now available.
You can't refuel a disposable descent stage.
And with the added complexity of 2 stages and mixing storables with solid rocket fuel, it's hard to see how the development costs are going to be that much cheaper....
Isn't this exactly how NASA is doing it: designing SLS, Orion, SEV, undetermined-lander-in-the-future "in house"?
