I watched it live on NASA TV but did not see any flash on impact. Instead the Apollo 14 rocket which was crashed on the Moon has produces a big crater now seen and photographed by the Moon Recon Orbiter. Maybe the Centaur rocket was less heavy than the big Apollo launcher.

How´╗┐ deep were the impacts? Anybody know?

I can't saw a sign of a debris cloud.

What happened to the debris cloud?

The scientists said the blast caused will be strong enough to fly the pieces of the lunar surface. Fragments will be observed from Earth through a telescope measuring 10 to 12 inches or greater than that. And this 'fly the pieces of lunar surface' we call it as the debris cloud.

As Master Tullio said, we did not see any flash on impact. Looks like nothing was happened in Cabeus crater.

Was interesting until impact horizon, sort of expected a bigger "poof" or "plume" of a debris cloud - but having never witnessed a lunar impact by telescope, maybe that's all there is to it for low-speed high-mass objects.

Wonder why they picked that crater - plenty of others with sun-shadows and deep enough that would have been more visible - but I suppose it wasn't about public entertainment.

Am curious if someone can translate the last bits of verbal communications going on - the transition from 1hz to 1mhz, for example (cameras?)

I believe they chose the crater they did because the strongest indications of possible water ice were from there. I've heard that 1 MegaHertz referred to the bandwidth of the signal. 1 Hertz apparently means one image sent per second. They were reportedly tinkering with the image rate so as to cope with unexpectedly large data files they were receiving, just before impact. In order to get all of the information in each image they would have had to compensate for larger than expected amounts of data, by slowing the rate at which the image was refreshed. Michael
