Neat, where did you hear about this lake?
Q: That translates to what in volume?
A: We were very conservative in the press release, but if you take basically 100 square kilometers by roughly 50 feet, you get a volume of something like a quarter of a cubic mile, I think it's on that order. It's a considerable amount, but it's not a huge glacier or anything like that.
Q: Can you compare that with something you know?
A: It's a lake. A small lake.

I've always wondered about water. How did water arrive on earth? Has it always been there?
And then we have comets.
These are icy bodies that occasionally careen into the inner solar solar system from a massive area of space around the sun called the oort cloud.. But this is an enigma.
Where did such a massive amount of liquid water come from to create these objects? How did these comets form? All of that ice just seems to be lingering out in space for no good reason. But there must be some kind of explanation that makes sense.
Now, I can understand the possibility of comets raining down on the planets of our solar system and delivering water like a milkman would deliver milk. But these would also be massively destructive events as we saw when comet Shoemaker-Levy9 slammed into Jupiter a decade ago. And that was even after it was fragmented by Jupiter's gravity.
I can also understand how comets would probably have been more numerous around the time the solar system was formed. Hence, there would have been many more smaller-sized comets capable of hitting earth without destroying it which would have also brought water to our planets (and other planets). But where did all that water really come from? Was it part of the body that would later become our sun? Has our solar system simply ensnared the leftovers of ancient planetary "debris" with it's gravity over time? Alot of important questions to consider. But the important thing to remember is.. Nobody knows.
I guess, personally, I'm just not convinced about comets bringing water to the planets. Whatever created the water that ended up forming comets out in the oort cloud could just as easily be responsible for putting water on earth and the other planets. And since we don't know how that all happened, we don't know what possibilities are out there which might also explain how water got here on earth.

So they've found this massive frozen lake on the moon. . . Well please explain why NASA want to blow the bejesus out of it when this frozen water would be usable for future astronauts stationed on the moon? It just doesn't make any sense. The best NASA can do the day after they blow it up is say, There's water on the moon! Well, there was water on the moon, but we've just blown it all into space and possibly contaminated whats left!
The Moon doesn't rotate, not like the Earth does,
Sidereal rotation period 27.321 582 d (synchronous)
Equatorial rotation velocity 4.627 m/s

Sun spots show us that inside Sun is "black".

Another one:
Earth stole water from Moon. Ever since Moon is trying to retrieve its water, but cannot. Creating tides and affecting reproductive cycles of females is all it can do. Now, NASA is trying to find water on the Moon, but I'm afraid we took it all long time ago.
Mars was hit by a water planet (like Europa, Jupiter's moon, for instance). If you look at Mars you will see that one big part of it seems to be "washed" with a giant splash. The remains of that water planet are now comets. This splash also removed atmosphere and other things from Mars.

Most scientists currently belive the earth is around 3.8 billion years old.. Mainly, we get this date from radiometric dating of rocks (sometimes called radiocactive dating). All based on the never-changing decay rates of radioactive isotopes.
It now appears that MOST of the moon rocks retrieved during the apollo missions are, indeed, around 4.5 billion years old. Wikipedia sais some of basaltic type samples retrived from the lunar Maria have been dated to around 3.16 billion years.
This doesn't mean that the moon wasn't initially part of an earth "twin". One of the unresolved issues of this theory deals with the fact that there isn't alot of evidence suggesting the earth ever had a "magma ocean" which it undoubtedly would have had after such a violent collision. Everything points to a collision of some magnitude creating the moon as the geology all suggests the moon was once completely molten. But that doesn't necessarily mean it had to be with earth. Scientists have dubbed this mars-sized impactor "Theia" and I think only reason they think it was "mars-sized" is because all the calculations and computer models best suggest a body of this size would have been needed to expel enough material to accrete and form a moon of this size.
But if rogue planets were just flying around hitting other planets, how many planets were really out there prior to all these collisions? How many collisions really took place? It's quite feasible that "Theia" actually collided with an earth-sized planet with an orbit close to 1 AU (but not exactly). The compositions of earth and its twin would have been extremely similar due to both planets forming in the same area of the proto-planetary disk of the early solar system. The collision takes place, the moon is created, but it, inevitably, gets slung out with an oblique orbital pattern until it becomes captured by earth's gravitaty field. This would explain ALOT
It would explain the moon's high angular momentum.
It would explain why the moon shows evidence of a magma ocean but not the earth.
It would explain why the composition of the moon is very close to that of earth with slight differences.
It would explain why most of the moon rock samples are almost a billion years older than earth.
(radioactive dating doesn't really lie).
The Moon doesn't rotate on an axis like the Earth does, our rotation is what gives us our day and night.
An experiment, begun when Apollo 11 astronauts Neil Armstrong and Buzz Aldrin left a mirror on the lunar surface 40 years ago to allow Earth-based astronomers to fire lasers at it, has been ended by American science chiefs.
The National Science Foundation (NSF) last week wrote to scientists working at the McDonald Laser ranging station at Fort Davis in Texas to tell them the annual $125,000 funding for their research project was going be terminated following a review of its scientific merits.
I believe this has happend in the 1980ths all ready
