Answer to Question 1

Mars is small, and most of the time so distant from Earth that amateur telescopes have a problem seeing anything but an orange disk. But when the Earth overtakes Mars every 2.2 years, Mars gets close enough to us to appear much larger and to show a good deal of surface features and atmospheric clouds, polar caps, and dust storms.

Answer to Question 2

E
