I've made a new video!!! smile This time about a boulder on the Moon.



The other day I discussed whith a conspiracy theorist friend about the Moon. I showed to him that there are not only 4 or 5 photos that NASA has released but hundreds. In fact they have released so much that in the case they want to photoshop/draw them they would need a lot of people doing that. Too much people. He stated that all images where fake (yeah, not only the landings) and that "we have to believe" like indoctrinated people that the far side of the moon look just like NASA says (yeah and then also Roscosmos, ESA and JAXA need to be in the same shit).

Just de LRO mission sends us 1000 images per day (200 MB each) that are publicly avaiable. He refused to admit that this was interesting enought to change his mind about the "lies" of NASA about the moon (even if what I said means that every two minutes NASA draws a gigapixel random image that probably no more than ten guys will ever search on the archive), but I liked the conversation because it inspired me to make this simple video. Why anyone would make such a simple and elegant consistent panorama of the moon with such detail? Here you have a boulder rolled down the hill. Quite poetic for an astrophysics student like me biggrin

FastFourierTransform, that's a beautiful video. I'd never known of that boulder, and probably wouldn't have if you didn't share it, so I'm thankful. :)

Pity about the dimness that is conspiracy-theorist thinking though.

Interesting to see that rock. And there are many rocks that have rolled, or judging from the image, bounced downhill in that area. I wonder what triggered them to tip over.

And when. These tracks could be thousands of years old.




Don't forget to look here.

A nice 360 degree view right now from our meteor station in Harestua, 30km north of Oslo. And a chance to test the equipment in cold weather. Big image, zoom in to get details.

I aprreciate that smile thanks. Very elegant

Yes, that's insteresting. Considering the fact that there are not atmospheric erosive processes (as to cut a block and make one part roll down), no eruptions and no tectonics I can only imagine some kind of quake due to an impact in the area.

The image I used is this
http://wms.lroc.asu.edu/lroc....89691LE

You can see the boulder in the upper-central part of the strip (rotated 180 degrees with respect to the youtube video).
As you can see, the track of the boulder starts in a boulder field and ends, logically, at the boulder itself. There are other rolled boulders in this image (this is the bigger one) but two of them have have tracks that start at some part of the track of the big boulder. I think that those smaller boulders where kicked by the bigger one when it was falling and made their own trayectory like a small avalanche.

Thats also something that troubbles me. You can clearly see at the near the end of the boulde track an impact crater more or less as big as the boulder itself. This impact have been made after the boulder rolled. There are also tiny craters of 2 and 3 meters superimpossed over the track (just a few, three or four I can count), this means that the boulder rolled quite a long time ago. You can also use the craters that overlap the track of the smaller boulder (send to the upper part of the strip) because both have occured probably at the same time in history due to the fact that the smaller boulder was probably kicked by the bigger one. You can also see the overlapping of small craters.

I don't know precisely how old this event was but probably it was so long ago that we can talk of geologic timescales (at least millions of years). Some boulder tracks have been dated like that thanks to the MoonZoo project.

You can also see some boulders bouncing making discontinuos tracks (lunar weaker gravity explains that maybe).

That was my first thought, too. But, there are great temperature changes on the Moon - 2-300 degrees C difference over a month. And if that causes only a few grains of lunar dust to move slightly every time, that would accumulate into large changes of the lunar soil if the cycle is repeated a million times. If you made a timelapse video that compresses 100.000 years into a minute, I could easily imagine the surface as something appearing very volatile even if we could exclude new dust due to impacts.

Some mother of pearl clouds yesterday. Not a big display, but the first this winter. I was expecting these after the hurricane that hit Norway this weekend.

I've been making improvements off and on to my galaxy generator. Unlike SE's, it's fully procedural, i.e. there's no galaxy image used, only cloud sprite images; and it animates in real-time (although much faster than real speed wink ):

It can also simulate polar jets, for use in accretion disks:
