They need a lander that can either land about 10klb cargo on the Lunar surface or bring two crew with some payload ( 1,050lb total from their PDF ) from LLO to Lunar surface and back to LLO with a single stage. With one type of lander this would give them the flexibility to offer crew or cargo to the Lunar surface. Having the lander large enough to send the crew in a pressurized cabin ( SEV ) would be better, it could be built later. And that would probable be a reusable using Lunar made LH2/LOX or CH4/LOX.Edit:SEP could be used to bring the lander from LEO to LLO.SEP could be used to bring a tanker ( refuel lander ) and cargo for lander, SEP could have robotic arms to help with the docking and transfer of cargo, plus with crew missions when a crew capsule arrives. SEP would then return to LEO for reuse.NASA is looking into SEP. Others might find uses for such a SEP system. GS could be the broker/travel agent not the designer of a SEP system, just a customer.Quote from: HMXHMX on 01/04/2013 04:21 amThere's not a living human at NGC who worked on the original LM, and none that worked on the LMDE, far as I know.This move is a reprise of Kistler hiring Northrop, or Teledesic hiring Motorola and Boeing, because some Wall Street firm told them to do so. It will end the same way.It will end the same way.Why? If there is enough funding then why would Northrop not be able to build the lander? True the people of Apollo are all probable retired by now, however can't the new generation rebuild the lander with modern tech?Is there that much bad politics to not go to the moon?If GS hired their own people to design and build the lander how would that be any different? Some young crowd.If GS hired their own team, it would cost them a fraction of what NGC will likely charge them. Northrop spent something like a quarter of Kistler's money and managed to produce a handful of composite airframe components, no more. Scaled (as one example) could have probably done the same for 10% of the cost (at that time, late 1990s).Legacy aerospace has little to no incentive to reduce development costs from what they charge gov't customers. To do so is very risky, since it calls into question why the price differential? I don't say it impossible that legacy aerospace can meet GS budget targets, but I'll bet GS never manages to raise the money. A multibillion dollar GS effort is doomed to failure, just as happened to Teledesic.I've seen this movie before.

Those numbers wont change in a hurry - they are most likely real world figures. People often agitate for cheaper manned spaceflight, especially Lunar missions. But they fail to understand that things cost what they cost; wishing them cheaper wont make it so. It will certainly take billions to set up the mission hardware and management infrastructure and the initial mission costs will be at least $1.5 billion each. In time, they may come down relatively speaking - but perhaps not if you factor in inflation.You might be right, but there might be ways: e.g., if you really want a legacy aerospace firm to build your lander, why not go with McDonnell-Douglas? They built the DC-X in 1991 for $60M, which is about $100M in today's dollars. Dust off blueprints for that, slap on a pressurized capsule, and you're good to go. Meanwhile, GSC is allocating $500M to develop their little lander. Divide that by 3, you get $167M, which compared to the DC-X cost is reasonable.Similarly, they allocate $500M for a Lunar capable Dragon. Why should it cost that much? What do you really have to do to the existing Dragon that's going to cost half a billion USD? The $1.5B per mission price is approaching the cost of a flagship robotic probe. Granted, having human field geologists onboard is a force multiplier in terms of the functionality delivered, so it's actually worth it from a scientific POV. The problem is, you don't see these foreign space agencies launching a lot of flagship missions. They send discovery-class missions for $500M or less. Getting the price down to $500M would be a much easier sell for these agencies IMHO, and it would get it much more affordable for private individuals to hire a mission.Is $500M/mission reasonable? Well, if they went with an all reusable architecture, their main recurring cost is the launch costs. Even if it still took 2 FH's at $125M/each, that's $250M, leaving a 100% margin over their recurring costs.

Well, Grumman doesn't have a lot of cryo experience--correct me if I'm wrong. Does this entail that they will most likely go for the 2-stage hypergolic lander?
I'll repeat. Correct me if I misinterpreted. I feel like we are watching different screens at the same drive-in theater.I don't see their announcement as a commitment to have them build a lander or any hardware. They are buying a tranferrable set of guidelines from a reputable group. The cost could be rather minimal, and it's one of several 'architecture' study contracts with several groups. My assumption, when I first read the release, was that, data in hand from this, they would have a competitive process for companies who want to make the hardware. The hardware will likely meet requirements noted by this and other studies.
Ok, written it up, and made it a bit meatier with the NASA side of things:http://www.nasaspaceflight.com/2013/01/golden-spike-northrop-grumman-lunar-lander/

I am encouraged by the news if only because it means they are really spending a little money on the project. I agree with HMXHMX that picking someone like NG is likely to increase their costs compared to doing it themselves or picking someone else. Even so, if they can rope NG into sort of investing in the project, it may not be a bad deal. I'd prefer hardware, of course.
Oh whatever, the only thing the same is the brand! Everyone involved with the project is gone. And the most important relevant data is public domain right now. I'd go with someone with recent interplanetary unmanned lander experience if I'm going to look for demonstrated capability. Whoever built skycrane or Phoenix would be far ahead of experience four decades out of date and with no relevant employees.

Might as well say only Italians can explore another world, because Christopher Columbus was born in (what is today) Italy.Any customer who is aware that NG built the lander would know enough that they did so last 40 years ago! Anyone with near-term lander experience would win in the customer's mind.
What is better marketing hype than that your company just landed a nuclear Cooper Mini on Mars? This is a pointless argument.
