What was discovered about the far-side of the Moon when it was first mapped in 1959?

• it was even more heavily cratered with no major maria

• pyramids were first seen

• the far-side was about the same as the near-side

• there were very few mountains

Interplanetary debris (usually micro-meteoroid bombardment) affects the lunar surface by

• reshaping it completely.

• causing more large craters to form.

• eroding the rocks into dust & soil ("regolith").

• adding more water-ice everywhere.

Why was the discovery of water-ice at the Moon's poles so significant?

• there could be a possibility of life there

• permanent human outposts can now (eventually) be established

• water can be used to power lunar rovers

• new crops can easily grow in lunar soil (regolith)

"On September 27, 2015, a rare total lunar eclipse of a supermoon occurred. A supermoon occurs when the entire lighted half of the Moon faces Earth [full Moon phase] and the Moon is at its closest point to Earth in its orbit. At this time, the Moon will appear 14% larger and 30% brighter than normal. Supermoon events are rare, but a total lunar eclipse during a supermoon is even more rare. There have been only six total supermoon lunar eclipses since 1900. The next one will not happen until 2033. "

Supermoon total lunar eclipses are celestial events that

• are random occurrences

• will never happen again after 2033

• are predictable

• will happen every full Moon

The Moon has more surface craters than Earth does because the Moon has

• a smaller diameter than Earth

• no significant atmosphere

• a surface more sensitive to impacts

• a stronger gravitational force

The passage of the Moon into Earth's shadow causes a

• lunar eclipse

• New Moon

• solar eclipse

• Full Moon
