One of the commentators identified that hotspot as sunshine hitting the crater rim. I thought it looked like an impact site myself - perhaps there is some confusion about that.

Every time I see the impact story on the news, the media tends to over play the impact.


Yeah, the CNN caption was "NASA Attacks the Moon."

That hotspot was visible before the impact - I think its just the crater rim

Some of us were doing an image sequence with a 0.9m telescope in Arizona, with the moon nearly at zenith. Nothing obvious in Cabaeus as we watched the data come in. I'm turning around now to try aligning and differencing the image to see whether we can tease out a more subtle plume signature.

Edit 40 minutes later - difference imaging shows no plume detection within limits from telescope shake and seeing (which can be improved but not in real time). That makes sense if the SSC only saw a subtle signature.

oh well, that was anticlimactic. As it's going to be hours at least before other images are released and with the news channels in full mediagasm mode over the prez' Nobel, I really don't expect any data until next week. g'nite!

I'm already dreading the headlines: "NASA Moon Bomb A Dud", etc. ad nauseum. Sure hope the science was a success; have to find out after work. G'night/G'morning everyone.

I'm very sorry you felt disappointed. I can understand why - no bright flash. But the real treasure could be coming to us.

That's my stance too. We haven't seen or heard from LRO or HST.

I recall hearing that science return aside, they would be quickly able to determine if the mission was a success or not. While I have very little doubt that LCROSS will return data, has there been any word from the LCROSS team itself?

From LCROSS shortly after Centaur impact...

Last frame from LCROSS video before it cutout...
Attached Image


....I think that the whole sequence was fantastic. cool.gif
Watching the Moon's surface rush towards us reminded me of the old footage of Ranger heading for impact.
The anticipation/tension of the whole thing was great.
Was anyone else leaning closer to their screen hoping to see something?...ANYTHING!

There's going to be more data here than we can see right now.
Let's wait for the press conference being held in about 90 minutes.

In a way, I'm glad there was no 'flash'....that might convince some media/public that it wasn't a bomb! wink.gif

Oh definitely, absence of the Centaur impact aside, I definitely enjoyed it. I, too, leaned closer =)

laugh.gif !, mchan!

Oh, I'm not disappointed personally, and of course the real gold will be in the properly acquired & calibrated data. In all likelihood the popular media's gonna be a bit snarky, though, and that's always not the best for NASA.

I was thinking that this would be a good trick to try on one of Mercury's poles someday, with the caveat that the chase spacecraft would have to do a grazing flyby--not an impact-- & survive at least long enough to play back the observations.
