The harvest moon--which came a couple weeks late this year, on Oct. 4--has long allowed farmers to gather their crops late into the night, using moonlight as a beacon.
Someday, the moon might yield a harvest of its own, thanks to a natural supply of water. A NASA probe is set to crash into the moon this week in search of that potential bounty. Here's how you can watch it from here on Earth.
In the 1960 cartoon "Hits and Missiles," Popeye the Sailor Man accidentally crashes a rocket into a moon made of cheese.
Popeye soon realizes he needs more fuel, "so we can gets back to Oyth," and he goes looking for help.
When a group of NASA scientists deliberately crashes a rocket into the moon this summer, they'll be looking for fuel, too -- in a way.
