The Far Side of the Moon - And All the Way Around
3.11.11 - Because the moon is tidally locked (meaning the same
side always faces Earth), it was not until 1959 that the farside
was first imaged by the Soviet Luna 3 spacecraft. And what a
surprise - unlike the widespread maria on the nearside, basaltic
volcanism was restricted to a relatively few, smaller regions on
the farside, and the battered highlands crust dominated. A
different world from what we saw from Earth.
Of course, the cause of the farside/nearside asymmetry is an
interesting scientific question. Past studies have shown that the
crust on the farside is thicker, likely making it more difficult for
magmas to erupt on the surface, limiting the amount of farside
mare basalts. Why is the farside crust thicker? That is still up for
debate, and in fact several presentations at this week's Lunar
and Planetary Science Conference attempt to answer this
question.
