Even Phoenix is playing with Doug's nerves
I start to think the WE may be right BTW, I didn't understand the same as Marcel. I think they said that the arm cannot get to the ice like feature. -------------------- |

With the benefit of the first look under the vehicle clearly showing that several cms of surface cover have been blown clear by the thrusters, I think the recently emplaced dust is visible where it fell across the work volume - a sort of pseudo ejecta blanket. Here's a crude doodle over Doug's stitch. It looks like the bottom four-fifths of the image, the grayer material, was blasted there. (It's harder to make out on the left-hand image, the colours change at the seam line - a lighting effect presumably.)
I also doodled arrows where the rolling rock appears to have, er, rolled. Those three knobbly blue-green/white-ish "pebbles" just above the roller's path look different from the rocks others, don't they? -------------------- --

Those three knobbly blue-green/white-ish "pebbles" just above the roller's path look different from the rocks others, don't they? Yeah, they do. Speaking as an utter ignoramus concerning color composition/gamma/etc., are surface tones exaggerated here? (I know that the "true color" of Mars surface pics are about ten light-years beyond problematic.) Anything greenish-whitish in this area might well be an ice candidate. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I've been having a lot of trouble getting onto the University of Arizona Phoenix website (http://phoenix.lpl.arizona.edu/). Are Phoenix related sites really under denial of service attacks? Who would do that? What would be the point?

Well,I hope this guy is proud of himself. I guess we have one advantage over him.
Every morning when we look in the mirror we don't see "Vital" looking back at us. -------------------- |

Well,I hope this guy is proud of himself. It doesn't even look like much of a hack - he's managed to add (or modify) a news item, but that's it. No new files uploaded or anything - sounds like he's only managed to access the database. Not exactly 'owning' the server... 'Vital', you're rubbish! And annoying. Especially as there could be loads of new, interesting raw images appearing around now. Sigh... |

Back on the stone issue. The more little stones seams clearly blown away.
Now, what about the big stone large enough,the underneath would touch the ice so it would have slided on the ice. That could be consistent with the long trajectory with respect to its size. -------------------- |

Pardon all the typos in the below, it's my notes from part of the press briefing, Uwe Keller talking about the image. Will post more later today but wanted you guys to see this before Europe goes to bed
QUOTE It's like you go down and look through your legs, so the image when it came back was upside down. What we see is astounding, because looking south we see illuminated surface of soil, you can see shadow of leg struts on surface, and in foreground you see dark shadowed ground underneath the lander in shadow. A large part of the surface is uncovered by the exhaust of the thrusters. It is tabular, shiny, and smooth, and this is a strong indication that we are looking at the icy table just covered by a few centimeters of soil. The thrusters during the landing uncovered this part. And you can see some down grade from the foot to the center of the image. The purpose of this image was to look at the third leg. If you follow the shadows of the legs, you can see that the shadow is bent, strongly indicating the gradient in the surface, the soil is several centimeters higher than the smooth whitish surface. Clearly indicating that the surface is uncovered by the thrusters. The fact that you see relatively large parts being flat indicates a table of ice. So wherever we will be digging, we will hit ice after uncovering a few centimeters of soil. At top of image you can see three thrusters which were used during the landing. Peter: We're doing 60 Mb per pass, 2 Odyssey passes per day, twice as much as we were offered. Starting to compress images less and take more filters. Even with non-use of MRO, we're still data rich. King of Hearts is way to the left, just ot the left of national park line, for next 2 or 3 days we'll be doing digging operations. We brought down web page to fix problem, but didn't lose anything. Uwe: try to look for changes. We already repeated observation, but we don't expect to see differences on short interval. The sublimation rate may be a few microns per day. This depends on model you take, whether you add some ice or you lose some ice. It depends on wind velocity Observation for today, high priority we introduce some additional observations of first leg, where we saw patch we now think is ice. This patch we can get close enough so that we can use color LEDs and can produce an RGB image which means we can produce a color image. We can tell albedo of a particular patch and give us much more confidence in decision whether this is really ice or not. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
