First-ever pics of lunar polar crater interiors released A NASA radar instrument aboard India's Chandrayaan-1 Moon orbiter has sent back the first ever images of hidden crater interiors at the lunar poles. Space boffins hope to use such pictures to discover deposits of water ice, which could be invaluable for future Moonbase astronauts. NASA overlay of Mini-SAR imagery from …
It is an ordinary optical image (Earth-based, Arecibo Observatory radar telescope image), except for the strip from the new sensor. I assume that the strip was overlain on the existing image to give context and a before/after comparison. In that strip, you can see the crater floor that is black in the legacy image. The implication is that further strips will follow, filling out the remaining shadow.
The Aricibo radar has the same view as an optical telescope looking from Earth. It can't see the polar regions well either, so my guess is that the large area photo is from one of the earlier lunar orbiters, not the Aricibo radar. Besides, it has the look of an optical image from the Apollo era. You'd expect the crater interiors to be dark since the sun can't shine into them, which is why selenologists think they might have icy bottoms.
That's because it is an ordinary picture. If you read the caption (why do people not read!!) you find that the big wide rectangular thingy is an overlay from the SAR imaging onto a bog-standard optical telescope image of the moon. It's so you can go 'oh, it's the moon - I get where that is' rather than being shown some SAR image that you can't quite figure out what the hell is because you're clearly a retard!!.

"Scientists believe that tying in ... will find anything of value ..."
Not just scientists! Only connect > "... built by the US Naval Air Warfare Center ..." Intriguing, given that on the Moon there is no war, no air, and not much of the USA.
Well, well, well. (And I'm not referring to water). Do you suppose the USN is looking for somewhere to float their boat?
If the USN has such expertise in synthetic aperture radar, why hand it on a plate to an alien government (no slur intended on Indians) which already has the technology (BrahMos) to blow entire carrier groups to fine powder. A little bit of blackmail? Perish the thought. More likely the USN has cottoned on to the CIA's game of ex parte deus ex machina, and decided that's what sauce for a loony goose is sauce for a saner gander. All of which is peripheral to the question - how will water on the Moon float the USN's boat - or are they lining up the rubber ducks for the next turkey shoot? (To take place on either a New Moon or a Full Moon).
"Can't miss it, straight lines and everything!"
There are more than 180 angles in any direction that a meteorite can hit the moon as it has a curved surface.
Of all the angles it can be hit at, there is only one 90 degree one. There are three hundred and sixty directions for every other angle.
So why are the majority of craters symmetrical? That can only happen if they are hit at 90 degrees.
And there are considerably more than 360 angles in a circle. 21,240 minutes for a start. Still only one perpendicular though.
That is proof there is either water or life on the moon. The trick is to make sure the British don't get there and start managing it.
