Sol 309 - Another "un-popped" bubble? Was checking out a few frames from Sol 309's navcam shots in stereo and noticed this. The raw image is here. It's clearly not the same one seen in this area before from Sol 121 (from FredK's Post, and then one of mine), but interestingly, it appears to have a similar knot or "nipple" at the top. There's another slight "hump" in the rock just below it too, and though not as clearly defined as a true "bubble", it has the possible look of one of the elongated or egg-shaped variety. The location is close to the right side of MSL as seen from the Sol 309 Navcam shots, in what would be off and just beyond the extreme lower left of Damia's excellent mosaic a few post's ago above. It'd sure be interesting to "pop" one of these things open and examine the undisturbed material inside... Anaglyph View: Cross-eye view: |

We stopped near one of those 'bubbles' between our locations on sols 122 and 123. Yup - and these things are sure interesting... Sol 307 "Bubble" in stereo - & looking just as enigmatic as before... A Cross-Eye version... ~ AND ~ The missing MC frames from the Sol 298 and Sol 302 stereo panoramas are finally in, offering some Nice Big anaglyphs. Links to the 2-D versions are below too... Sol 302 - Point Lake Anaglyph - (2-D version here) Sol 298 - Overhanging Outcrops Near Sheepsbed - (2-D version here) BTW very nice imagery from everyone of late, it's so great to be rolling again... |

A Few Anaglyphs of recent activities... Sol 292 - Cumberland drill hole night shot MC34/MC100 pairing- The MC34 image was unrecoverably overexposed where hotly illuminated but it still makes for a pretty nice stereo view.... Sol 297 - Animated GIF of MSL drive movements from front hazcam - total of four frames (at different positions) with a 3 seconds pause for each... Sol 297 - Navcam panorama from the new location after the short drive... It's great to be moving again... even if just a few meters for now... |

Sol 279 - Close-up anaglyph of the drill hole. Seems to my eyes they offset MAHLI just enough for a good human eye separation value. Lots of detail in here. The anaglyph at least feels like kneeling just above the site. And there's a New JPL Video (May 16th, 2013) about drill sample processing. Gives a good idea of the drill size when Avi Okon is holding it in his hand... Here's a cross-eye view for those without anaglyph specs.... |

With the four Sol 275 MC-34's now in, here's an anaglyph of the recent area of focus. The yellow rectangle outlines the patch being scrutinized by MAHLI imagery of late. The left side of this rectangle is the top in the MAHLI images. And BTW Jan... beautiful work on the Navcam pano with the integration of Mt. Sharp. Nicely done! |

Thanks Emily. From reviewing several "comic ray hits" on other space images from around the web I'd say you nailed it. They seem to take a wide different forms too, not dissimilar to the one I referenced, as in this MSL night image from sol 113. Very similar in pixel spread and appearance. It's placement low over Mt. Sharp is what threw me. |

Kind of off topic, but does anyone know if the left and right front hazcams actually take their respective stereo images at exactly the same time? The time stamps usually appear as identical with left and right pairs, but is their a slight difference in the actual imaging time of a few milliseconds? I ask because while scrolling through the 14 images taken on Sol 276 (the entire sequence is here), I noticed a bright "smear" in the sky above Mt. Sharp that appears only on one particular right hazcam image of the sequence. The corresponding left image, lacks this anomaly, as well as all the others in the sequence. The JPL raw image page time stamps both left and right images at "2013-05-16 16:45:59 UTC" Is this a processing anomaly or a lens glint? If it's a glint then from what? The cameras appear to be in full shadow. Upon closer inspection it seems to almost have a "nucleus" of sorts, (one very bright pixel) and even a wispy looking "tail" associated with it. It certainly seems highly improbable this could be daytime meteor trail, but it almost has that kind of look. If the hazcams take their frames at precisely the same moment then of course it's not or it'd appear on the left image too, correct? . Just wondering what might have caused this because I don't recall seeing many distinct single frame hazcam anomalies (like this one anyway) very often, and it doesn't have a 'digital glitch' look at all due it's wispy nature. Most likely a sun-dog on the lens then? Caused by what though? A reflection off the turret? ... same image with levels tweaked to bring out details: |

It may provide a certain feeling of a push/release action of the rover arm on the presumed new drill target; the action seems to tilt the rover a bit. Thumbing through at the Hazcam sequence from sol 276, I noticed that little "camera jump" too Gerald. The drill was down at the time, and there appears to be a distinct dark diagonal scar in the MAHLI close up of that area on Sol 276 that wasn't there on Sol 275. The contact looks to have been focused on one of the raised nodules. The original raw images are here: Sol 275 & Sol 276 |

Animated GIF - anaglygh version - of the Sol 268 "Moving Shadows" sequence. This one is comprised of 15 frames at 7/10ths a second per frame. I left it at native resolution (cropped to the R-L overlap at 784x1020 pixels - and at 8.38Mb in size) so it may take several seconds to completely download before the animation starts re-looping at that rate. |

Once your eyes lock into stereo that's a great Navcam animation Gerald. And you were spot on with your 3 frame GIF a few posts back about the drifting evident in front of the rover. I hadn't noticed it at first - but yup it's there - especially in the area a bit to the left of the drill site, and even more detail now very clearly illustrated in your color GIF above. I was hoping to render an anaglyph version of it but there was no MC 34 counterpart on Sol 234. Shucks. But here's an (non-animated) anaglyph view of the Sol 267 MC34/MC100 pairing of the drill holes. |

Back to the new pics: here are a pair of hazcam comparisons, between sols 215 and 262. Lots of differences in the foreground, with dust shifting in the wind and tracks degrading. Indeed. Here are a set of ANIMATED GIF's that toggle Sol 215 and Sol 262 every 2 seconds (in both 2D and Anaglyph versions) from both the rear and front hazcams. There's certainly some drifting evident in the vicinity of the tracks in the rear hazcam views, especially in the little hollows on the bare light colored rock face at center left, just left of the MSL shadow. The tracks themselves seem to differ in various aspects as well, though less obvious as to the nature of the changes. In contrast, the front hazcam shows little difference anywhere except the drill site debris. I suppose it's a logical assumption to speculate that where the soil has been disturbed by the wheels, the newly loosened soil is thus more easily dispersed by the wind. Perhaps everything else is slightly encrusted enough to resist much wind drift under normal conditions. Good to know I suppose, if obtaining an otherwise "clean" surface sample anywhere near wheel tracks is the goal, especially if a few weeks of time have passed.

Sol 225. Morning anaglyph views from both Front and Rear Hazcams. Of particular interest in the front view is the brightly illuminated vein catching the sun just between the wheels, and the nice range of depth - from the underbelly all the way to Mt. Sharp. Rear view offers a good views of the wheel tracks behind the rover. |

Does this mean that RAD will not be operational? Too bad; such measurements would be very interesting. There's a Dr. John Bridges of the Department of Physics and Astronomy at the University of Leicester (UK) who states on his MSL blog (dated today) : QUOTE "Data from our Radiation Asssessment Detector (RAD) instrument will help document the intensity of this solar storm...." If he's really a person "in the know" on this particular point - RAD is recording the storm data... They've also today announced a 10 a.m. PDT (1 p.m. EDT), Tuesday, March 12, News Conference to discuss the first sample of rock powder. Looks like this one is to be broadcast not only on Ustream but NASA TV as well. |

Ken Herkenhoff's USGS Blog today, March 6th, 2013: QUOTE "Rather than continue with recovery efforts, MSL will be shut down due to intense solar activity. A big "coronal mass ejection" is predicted to hit Mars on Sol 207, so the rover will be commanded to go to sleep to avoid problems like the Sol 200 anomaly. Space weather can by nasty!"

Mike, I first noticed the three 34mm spots a few weeks ago when proofing a large anaglyph. They're hard to see in 2D against the surface because of the jumbled noise in the terrain but pop out subtly as 'floaters" when viewed in stereo if not cleaned before anaglyphing. The four frame animated GIF below (from the raw Sol 184 set) points these three culprits against the relative smoothness of an out of focus robotic arm... Your post made me curious as to how long they've actually been there, and to my surprise it looks like they've been present since the first good 34mm shots came down on Sol 3. You can see them in the same positions (as in the GIF above) at the center of this full frame series from Sol 3: http://mars.jpl.nasa.gov/msl-raw-images/ms...5000E1_DXXX.jpg. Now knowing now where to look for these - especially easy to spot if one flips rapidly in an image viewer at any large 34mm set - and yup, they're there. |
