  Fill in the blank(s) with correct word

Question 2

Observing Galilean moons: The Galileo spacecraft launched towards Jupiter carried a small telescope (about 25 cm diameter) for collecting visible light images.
 
  Explain why these collect images with much better spatial resolution than even the largest Earth-bound telescopes (for example, the 10 meter Keck telescopes).

Answer to Question 1

faulting and deformation, or tectonic activity

Answer to Question 2

While they have much worse angular resolution due to their small size, these telescopes are so much closer to the moons as to compensate. The physical size of a resolved feature is a function of both the angular resolution and the distance to the feature.
