This I believe is true. There are valuable natural resources on both, that is true enough. The recovery costs at current technology levels don’t justify the means though by a long shot. It is too expensive to launch space vehicles from the ground and then you don’t have enough fuel to get to the moon (let alone Mars) anyway.

Yup. If we knew of a spot on the moon where gold bars were lined up - mined, refined, ready to pick up - the cost of retrieval still wouldn't make the trip worthwhile.

...And if we were rational human beings, I am sure you are correct.

However, governments all across the world spend money on projects which do not make sense financially - in spite of there being some committee or oversight group trying to make sure they spend wisely.

Technology or knowledge is far more important than gold bars. It can be used in the future to advance your country and give you the edge in warfare.

Are you positive? Because I'm not so sure... it sounds sensible to me, but wouldn't mouse ships be too small to see?

No because the friction causes them to glow brightly at they return ot he atmosphere with a load of cheese. . Or maybe it is their photon drive unit. Perhaps they just left the lights on in their ship. That happens all the time. I find lights on, holler about it and am told "It must have been a mouse, wan't me" They are really bad about leaving lights on.

Whatever the reasons those super fast moving objects people see in the night sky are always glowing brightly.

Not disagreeing there. But for those who see the Moon as a commercial base, that's the cost factor we're up against.

I like a cup of coffee. If we go with ballpark figures, a Falcon Heavy in non-recoverable configuration costs about 150 million and can launch 20 metric tons to trans-lunar injection orbit. Assuming, very generously, that we can make a low-cost soft lunar landing vehicle expending only 50% of the mass on vehicle and fuel, that's $15,000 per kilogram on the lunar surface. There are 2.2 pounds to the kilogram and a pound of coffee makes about 48 cups.

Lifting the beans alone - not counting the water and the energy spent in boiling the water or the entire apparatus needed to brew the coffee - adds about $142 to the price of a cup of coffee on the Moon's surface.

During your cup of coffee I ask you to consider what I said in Post #67. In spite of some people (Coldjensens) , attempting to mock what I said, it IS a valid point and it seems we (and other countries) MUST have this advanced technology already. It has been seen over Russia, over Europe, over China and over the USA.

Why do you continue to think in terms of rockets and jets?

There was a lot of technology that came from Space Exploration.

NASA's Spin Off website contains all the innovations that we use today that came from Space Exploration starting in the 60's.

Welcome to NASA Spinoff

Have you ever wondered how space exploration impacts your daily life?

Just imagine what discoveries and innovations would come about from a trip to Mars?

To be blunt, I don't believe the advanced technology that you postulate exists. Sorry.

No problem. I do not mean to be disrespectful in what I have said below.

However, enough people have reported it to make it more than likely that this technology exists.

Of course, you do not have to believe the newspapers which report it or the people who have witnessed it, but I wonder what kind of evidence you might need to believe anything. I completely agree that newspapers are not a good place to start when looking for 'evidence' of new technology, but when the military may be using it, it does not get reported in the same way as other science.

Scientists often disagree with each other and we often have 2 or more versions of how something came about, so how do you decide which one to believe and which one not to believe?

So finally, rather than reposting these links again here, here is a thread which gives some more details on this technology, newspaper articles about them, witnesses who have seen them, reported them to MUFON, and there is even a space.com website article.
