NASA's Big Moon Announcement

 The major announcement about the moon that NASA has been teasing is, indeed, a big one.

SOFIA, a telescope attached to a modified Boeing 747, has confirmed that not only is there water on the moon but yes, it is water, H2O, not any related molecule.

By flying at 43,000 feet it eliminates false positives created by water vapor in the atmosphere...going above the clouds removes most of this. Water has a very distinct molecular signature.

The weird thing is this water is sitting around on the lunar surface (there's not a lot of it), where we thought water wouldn't stay stable.

The moon is still a desert, but it's a bit wetter than we thought.
