What kind of spacecrafts are they huh? Are you saying that we have spacecrafts like those from the Star Wars movies????? And how does they monitor all the natural satellites in this solar system? Guess what, YOU DON'T KNOW THAT!!!!!!!!!!!!!!!!
Let me remind you of that until radar observations in 1965 proved otherwise, it was THOUGHT that Mercury was tidally locked with the Sun... Which means that the "tidally locked" interpretations about Mercury was based on theories, but these theories about Mercury showed to be WRONG when radar observations in 1965 proved that Mercury is definitely NOT tidally locked to the Sun at all...
How did the scientists find out that these other Moons also are tidally locked to their planet?

You really do need to read it again and more carefully.
Moduli says that the Moon does rotate.

Visual observations led astronomers to believe that Mercury's rotational period was equal to its orbital period. This turned out to be an illusion...
Astronomers have long known that Iapetus is tidally locked to Saturn because its albedo variations made its rotation easy to observe even over such a great distance.
Iapetus has been imaged multiple times from moderate distances by the Cassini orbiter. However, its great distance from Saturn makes close observation difficult. There has been one close targeted flyby, at a minimum range of 1227 km, on September 10, 2007; no additional close flybys are planned. One viewing opportunity is possible in 2015.

Yes Ladies and Gentlemen, pay attention and read how foolish someone like 'DJW001', 'Gibborium' and 'sra' make themselves look like and how they try to destroy the debates on this thread...
I want you to read it carefully again there, as you can see, 'Moduli' actually did say >>without rotating

You're doing a fine job at that all by yourself.
His second sentence is a question directed towards you, not a statement, so their is no contradiction.

Do you know what your problem is? You're acting like a bad loser because YOU refuse to FACE the FACT that the Moon does not rotate on it's axis in relation to the Earth...
Moon: Appearance from Earth
The Moon is in synchronous rotation: it rotates about its axis in about the same time it takes to orbit the Earth. This results in it nearly always keeping the same face turned towards the Earth.
Does the Moon rotate
Well, the Moon does rotate. In fact, the Moon takes 27.3 days to turn once on its axis. But the Moon also takes 27.3 days to complete one orbit around the Earth. Because the Moon’s rotation time is exactly the same amount of time it takes to complete an orbit, it always presents the same face to the Earth, and one face away.
Spinning the Moon
The Moon does not appear to rotate in the reference frame where the Earth-Moon line is fixed in direction, but it does rotate as seen by an outside observer.
Nice to see RIGHT THERE that you FINALLY admit that the Moon does NOT rotate in relation to the Earth.
And that's also what Alex Collier mean when he said that the Moon doesn't rotate on it's axis then he means in relation to the Earth, he just didn't think it was necessary to mention "in relation to the Earth"...

So, no comment on my graphics that show the tidally locked object rotating as it moves around the parent object?

...So that's my comment on your graphics... Ah, let me guess, YOU are STRUGGLING trying to understand my above comments to your question...
