from your own link:
"The initial sortie missions will last up to seven
days, performing science investigations,
resource utilization experiments and technology
demonstrations on the surface, before safely
returning the crew to Earth."
upto 7 days on the lunar surface..
NASA has never put 3 men on the lunar surface at a time and never more than 75 hours.. if constellation was planning to put 3/4 astronauts on the lunar surface at a time for upto 7 days.. straight away they dont have that capability... from 2 men to 4, its not just an extra 75kg/150kg of mass of the astronaut its not that simple..
you have all the mass of the consumables to support the two extra astronauts (food, air, water etc), the extra mass from the added living space, the extra fuel required to support the extra mass to return everyone to lunar orbit, proper waste management for 4 astronauts (not adult diapers for two astronauts)..
but anyway your article is more or less talking about lunar surface operations and you are using that as explaination of the missing technology..
so im guessing that you are trying to tell everyone that the missing technology is the lunar module or capability to soft land on the moon??

and what of it??? your hand-waving doesnt deny the facts..
do you know of any lunar module that is capable of landing more than 2 people on the lunar surface and launching back to lunar orbit???
you take engineers for granted.. thats your problem.. you have no understanding of the complexities of designing and building
a cessna 152 carries 2 people.. to design it to carry 4 people will be to nearly completely re-engineer/design the entire craft..

Do you ever check anything? Ever?
www.nasa.gov...
You might also want to look at how Orion planned to get to the moon, and see if it's the same as how Apollo got there.
Any time you want to tell us which technology didn't exist in the 1960's would be just fine.

You need to ask WHY it is not being done the same way as Apollo.
You say we have the technology to land man on the moon. The LM technology would be THE FOUNDATION in our development of advanced lunar landers.
Grumman built the LM. Forty years later, Grumman holds lunar lander contests?!?
Come on, man!

Yes, a Cessna cannot carry 4 people.
How might they go about developing a new plane, to carry 4 people?
Would they need to develop all-new technology from scratch, or use the Cessna technology as a base point?
Wright Brothers plane led to better planes. New planes were not being developed from scratch, with all-new technologies. Each was based on the previous planes.
Same as computers, etc. are not developed from scratch.
The LM should be used as a base point, for developing an advanced lunar lander.
So they ignore the LM, and have 'lunar lander contests'?
Now, do you get the problem?

This is why you fail consistently at this discussion: you do not have any understanding of what is involved.
Because they need to deliver larger payloads. They need larger payloads because of the different mission objectives.. The Saturn V rocket is still the biggest rocket ever made to get the Apollo equipment to the moon. The practicalities of this makes it very difficult to do in the same way the Apollo missions were done. Orion is also intended to provide a launch platform for different types of mission, not just lunar landings. Th Saturn V was much more a single purpose rocket intended to get the CSM & LM out of Earth orbit to the moon. If you'd like to prove that isn't what it was designed for, or wasn't capable of doing it, then you just go right ahead and prove it to us all. That would be just super.

Who says it isnn't the foundation? The Model T is the foundation of my car, but my car still needed a separate development programme to build it.

Furthermore, not do I not only say we both have and had the technology, I can prove it. How about your contention that the technology wasn't up to it? Can you prove that? I can wait for you to do that or I can go ahead and raise a family in the hope that you'll have the answer ready in time for my great-grandkids.

Second, the Ford Motor Company didn't need to stage annual "Build Us a New Automobile" contests, and give million-dollar prizes for vehicles that don't even work.
Ford and Lawrence Tech University (LTU) have again teamed up for a design competition asking prospecting students to reinterpret the Ford Cortina for the year 2030. The prizes include over $100,000 in scholarships.

They were planning to ADD other vehicles as it progressed, but the Saturn V was planned to be used throughout the entire program.
The Saturn V was (supposedly) designed for extended missions, and for building permanent moon bases.
You want to compare the LM to the Model T?
First of all, they didn't stop developing any cars for over 40 years (and counting).

Show me where they've used the LM technology as the foundation for developing new lunar landers... because I've never seen it.
You can prove we have the technology? Go right ahead, then.
To prove we DON'T have the technology is like proving flying pink elephants DON'T exist.
The claim is yours, so you need to prove your claim. It is not up to me to disprove your claim, if it's even possible.
If the technology existed, as claimed, and they went to the moon, as claimed, and wanted to return to the moon, as claimed, and planned to have similar missions to Apollo, as claimed, and planned to emphasize Apollo's "heritage technology" for those missions, as claimed....it would not have failed.
Not 'smoking-gun' proof, but it sure makes a convincing argument. And it beats your case, hands down.

That's right and after permanent moon bases they were going to build a fleet of Saturn V for Mars in the 1980's. Both Wernher von Braun and Vice President Spiro Agnew were talking about it during the Apollo program. But the dream was cancelled by Nixon and
NASA was ordered to stay in low earth orbit for 40+ years with the space shuttle decision (a decision very much influenced by Howard Hughes and his Mormon entourage, NASA administrator James Fletcher.)
Every US president has since upheld the restriction.
The Russians won't send a human being over 475km space altitude because they know the radiation will kill a human being or a monkey, any mammal, in fact, it is a Glass Ceiling.
Like all things that happened during Richard Nixon's first term we should remember the sage advice,
appearances can be deceiving.
It's not really possible to understand the meaning of "Apollo" without also considering the political will of president Nixon.
Sure, it was Kennedy who set the goal, Johnson who set up the circumstances for scoring the goal but it was Nixon who actually scored it, six or seven times in a row. No other world leader had such great luck in space exploration. If we included the successful return of the Apollo 13 crew then - this highly unusual sequence of success is as unlikely as seven consecutive royal flushes in a Las Vegas high stakes poker game.
Conversely, Skylab 1 & 2 were nearly-deathtraps for astronauts.
That was in Nixon's second term which is rarely, if ever, discussed on ATS.

Because no one cares.
