Deimos transiting the sun (sunspots also apparently visible)

If you look closely, to the right of the Sun there's a faint grey dot... I wonder what that is.


Dust speck on the lens or a lens artifact.

Something in the camera (notice how it doesn't move) Curiosity's Mastcams have image defects in every shot, these will be visible unless processed out (which they won't be on most non-NASA image products).

I wouldn't be surprised if a bit of dust got in during landing since it kicked up lots of small pebbles onto Curiositys back.

Phobos seen during the day



I definitely squealed when I saw this image biggrin

EDIT: I cropped the picture and edited to reduce compression artifacts

EDIT 2: I enhanced the contrast to make it easier to see the effect of "Mars-shine", the illumination of the dark side of Phobos by the light from Mars:





For comparison, here is the same shot in SpaceEngine (same time, resolution, and orientation)


Here is a closeup


Also, the picture was not exactly taken during the "day". It was taken at dusk, a few minutes after sunset.

*delete this, I guess? Sorry for making things a bit confusing since I had moved the post before Harb said I didn't need to*

(just a quick thought, maybe we can remove the countdown from the thread title? not that it's needed anymore).

http://www.space.com/18626-n....on.html Some speculation stuff and also a caution on overhyping. At the end, it says that none of the team said anything about earthshattering or anything like that Still, to have it be 'top secret' like this means that they want to be really sure that they are seeing what they think they are seeing before they make it public and that they think it's something big.

And there is no sense in speculating further about it. Everything that can be discussed about it already has been. The reason they are waiting to announce it might be because it is very important, but also because it takes time to confirm the data. They need to analyze multiple samples and interpret the results and that takes a lot of time. If they announce something before properly confirming it - like they almost did with methane earlier in the mission - then it might turn out to be wrong and that would be pretty embarrassing.


I was just putting it out there, and yeah, like I was saying, they want to be sure that the discovery is what it is and interpreted properly before they announce it publically. I just kind of said that in a shorter way.

Hey guys, NASA is revealing the Curiosity findings today! Along with voyager findings, but that's unrelated to this post.

Edit: lol harb, you're fast. Or is this a new thing with the forum?

Edit2: Oh yeah, the announcement will be in about 1 hour1, 20 minutes at 12 p.m. EST (1700 GMT).

Oh, I had copied from the Space.com page, but thanks for the correction.

That one seems to have gone to video file for some reason, http://www.ustream.tv/nasajpl should do it. Too bad it doesn't have captions :P

Edit: I wish I could instantly filter the crap out of the chat sidebar because there is tons of i, which unfortunately, is 99% of that chat. :P At least until the moderators got things under control.

Edit2: So, basically the big discovery is that they found water and lots of it at rocknest, with lots of heavy water? Going by the images here.....

Edit3: Inferring from what I got off the chat over there, the big discovery (I'm assuiming) is that they found carbon compounds (with chlorine), but they don't know if it's native or foriegn.

Edit4: Space.com has an article up for it: http://www.space.com/18741-mars-rover-curiosity-discovery.html

The MRO spacecraft has photographed the parachute changing shape over time due to being moved by wind.

It just wants to be free!

Edit: Actually, that'd be an interesting low-cost rover... pretty much just an artificial tumbleweed with a collection of instruments on it.

Edit2: What sol was that phobos image taken on?
