1.   A quarter-century after the first moon landing, the lunar dust has yet to settle -- at least here on Earth.

2.   A week later, we see half a moon, what astronomers call the first quarter moon.

3.   But refinements and modifications continued almost until shortly before the first moon shot.

4.   He talked about how he himself had watched the first moon launch, on a black and white TV.

5.   Other measurements show that Ganymede generates a magnetic field, the first moon found to do so.

6.   The Galileo already has used the small antenna to send close-up pictures of two asteroids and the first moon ever discovered orbiting an asteroid.

7.   With the first quarter moon, and the last quarter moon, we see half the daytime part of the moon and half the nighttime part.

8.   If a futher analysis of the data proves Io does indeed have a magnetic field, it would be the first planetary moon shown to have one.

9.   This reinforces the hypothesis of the existence of a magnetic field near Io, which would make it the first moon to have such a field.
