If it's successful the price of moon rocks should plummet to something far less than the entire cost of the Luna 24 mission per 170 grams of moon rock returned.Before Chang'e-3, we hadn't sent any landers or rovers to the moon since 1976 and I'm glad China is doing these moon landings when it seems no one else will.
Hopefully they've protected the electronics better than Chang'e-3 against the harsh lunar night (assuming it's still operating by then.)EDIT: I didn't RTFA. I assumed this was the sample return mission but it's not landing on the moon and China won't do a lunar sample return until 2017.
