There is a low bandwidth ODY pass that will happen in about 10 minutes that may have a couple new HazCams. Does anyone know when the first MARDI images are expected to be downlinked? I saw that 18 had been assigned a (relatively) high priority, but the JPL Ustream was just saying that the current pass would have only a HazCam or two.

Something could come down in this pass (thumbnails) but it could get bumped by higher-priority EDL data. Might have to wait for tomorrow morning's passes. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

If we see someone from Malin Space Science Systems on the panel at the next scheduled mission conference, then we can at least expect a solid update on Mardi; at most an actual peek at the data products.

Hi all,
Still sleepy (need nap), but I got an early glimpse of the planned MARDI thumbs. Worth staying up for. Oh so cool. I can hardly wait for the movie. We will all get a feel for just what a wild ride this really is. Mike Malin and his gang really know how to do this. So really, I am ok about sending a robot through it (even one that has been fawned over by thousands of hands), but sending a person through these harrowing adventures is really not something I could stomach. I will leave that to the next gen. POk so HGA deploy is later this sol. It is still only 7:20 am LST (3 pm PDT) and the rover won't wake for a couple of hours. (She has had a big day yesterday) I think this is the rough plan for this sol morning - but don't hold me to it - all times are LST: 09:46 Wake-up 10:00 LGA DFE (direct command from earth) 10:50 LGA Beep (our first x band signal from the rover to earth !) 11:45 HGA Deploy (its pyros have already been fired but this is the first time we will have moved it and it is the first use of the RMCA) (RMCA = rover motor control assembly ... a big box o FETs, FPGAs, RISC and other circuits with lots of wires coming out) More adventures to come. -Rob Manning |

just to be clear I do not know if the MARDI images will be shown at the 4 pm PDT press conf. They were very raw.

Those are the best kind, though the IMAX movie will be cool too. An IMAX film will be made with the MARDI footage? I guess this should make up for the zoom lens not being installed on Curiosity.

I think Mr. Malin stated the exact coordinates "to within a meter." Did anyone catch that?

It was the dust-blowing sequence that really blew me away. The rockets really kicked up a little maelstrom, there. I hope they weren't assuming that the body of the rover would protect the mast cams from blowing dust, cause it looks like Curiosity descended into a rather energetically blowing cloud of dust there at the end.

I hope they weren't assuming that the body of the rover would protect the mast cams from blowing dust... The Mastcams are pointed toward the deck when the RSM is stowed, there's a protective lip on the deck all the way around the RSM instruments, and there are long sunshades in front of the lenses, so I think we're good. More dust than I was expecting, though, at least visually. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

He also said they can map it's position to with cm using the full res MARDI pictures. Though like he said there is really no reason to do that (other than to show off ) -------------------- |

Seems like the thrusters cleared out the area under the rover. I would expect the ground texture outside the landing zone to be different, probably a finer dust with the larger pebbles just underneath the dust or slightly protruding.

That's really cool Doug! Once the powered flight starts you can really see the pitch down to get separation, then the pitch back up to null the rates, and then rock steady all the way down. Thanks!

Jennifer said the wheels are all aligned in the same direction, I believe she was mistaken in that small detail. She possibly had not really taken in the image the reporter was referring to and slightly misunderstood the question. If you look at the last images from the MARDI, I think you see the left front wheel toed in "40ish" degrees. It looks a little more, but I'm guessing there are fish-eye effects. |

Here's a HiRISE/MARDI comparison. I was short on time, hence the sloppiness!
If you doubt the final guess at the three small craters just near the landing site, download the YouTube video of the descent sequence and scrub (play forward and reverse many times) that final sequence and you can't miss those three craters that stand out in triangle formation. The crater marking the top point of the triangle is where the initial blast of the thrusters hit. Then a few moments later the rover seems to hover just a bit just to the right of the crater marking the lower right point of the triangle. After which the crater quickly slips up and out of view just before touchdown. What a blast! North is approx. to the left. EDIT: replaced original image with this corrected one: |

Walfy, your first image is mismatched (possibly throwing off the ones that follow, as well). Here's a correction:

Regarding the amount of dust kicked up by the descent thrusters.. It seems to me more than expected. Or am I just "preconditioned" by the non-thruster-landings of Sojourner and MER A/B; which resulted in initial sterile-looking appearances. Did the amount surprise the folks back at MC?

Walfy, your first image is mismatched (possibly throwing off the ones that follow, as well). Wow, that was sloppy! Thanks for spotting that, and for the nice way of comparing all of it in B&W. I've changed the image, updated my previous post. I'm still pretty sure the lower right crater in the triangle was the one which was nearly hovered over momentarily. |

Hello, I hope this is the correct thread - am posting in this one as I noticed previous discussion of the descent sequence imagery here. I'm wondering how much info could be derived about the MSL's hazard avoidance strategies from the sequence? I would suppose quite a lot - even as a non-expert I can see some horizontal motion ... wondering specifically about MSL's ability to choose the best landing spot. I realize the terrain is pretty benign already, but closer to the surface there must have must been some hazard avoidance? - BTW elsewhere, someone has also asked about the video indicating the descent stage shifting away from the parachute after separation, but I'm assuming the camera was only turned on after that separation?
Thanks and regards, Daniel -------------------- Daniel

No, MSL had no ability to perform hazard avoidance for surface features. The only hazard avoidance manoeuvre was just after release from the backshell when a horizontal manoeuvre was performed to remove any risk of recontacting the backshell/parachute.

Thanks James - so then, would any horizontal motions in the video be from other causes, for instance the descent stage moving to stabilize the rover? (compensating for pendulum motion for instance?) -------------------- Daniel

No, MSL had no ability to perform hazard avoidance for surface features. During the landing the EDL commentator said "we found a nice flat place, we're coming in ready for skycrane" (around 28:17 in this video). I wonder what he meant by that--that they just passively found a nice flat place? By what means did they get a measure of the flatness? -------------------- |

Daniel No the MARDI (Descent Imager) began taking pictures just before the heat shield was jettisoned during the parachute phase of the descent. See http://www.planetary.org/blogs/emily-lakda...and-part-2.html and the other resources linked in the FAQ thread at the top of this forum for a complete timeline of EDL events. I can't really tell which motion in the descent image video is caused by the divert maneuver. The noticeable movement at about 18 seconds into the video seems more twisting than anything else. |

I would have preferred a version at the correct speed. This one shows the last 2 and a half minutes of descent, yet lasts only about one minute. Looking forward to the full-size version with perhaps even some interpolated, generated images. |

Unless I'm missing something, we can use the MARDI image timestamps to resolve the question of when the first haz images were taken relative to touchdown:
http://mars.jpl.nasa.gov/msl/multimedia/ra...I1_DXXX&s=0 looks like about the first MARDI on the ground at 05:18:16 The haz images with the putative impact cloud are at 05:18:38 Seems about right to me. |

In all fairness, there's only so much you can do with the thumbnails.... That sounds like a challenge to me You're right, of course. But the little things we can do are interesting, until we get the big ones. Play with how they nest; try out a "real-time" animation; fiddle with colors/contrast; etc. Has anybody overlaid the MARDI frames on a CTX image yet? -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

For "just thumbnails," some of the MARDI mages are nonetheless jaw-dropping. E.g.: I'm having trouble processing how much better the full images will be.

TTT: That one (and only that one) is full-resolution. Thanks Emily! Glad to have my prior post corrected, because thinking of that image as a thumbnail was throwing my sense of scale way off. TTT (Also kicking myself a bit. Curious whether the image was in fact a thumbnail, and mindful of Forum Rules 2.2 & 2.3, I did, prior to posting, do a quick scan of the Sol 0 index page for Raw MARDI images. I concluded that, since I hadn't noticed any image that wasn't labeled "thumbnail," the image in question must be a thumbnail. The checking procedure is now exposed as defective both in design and in execution; I'll try harder next time.) |

A very simple elaboration Think if you drop a line straight down from the heat shield almost to the bottom of the image and then go a little bit to the right, that's where the landing site is. This is your image cropped to that area and rotated so north is (approximately) up: That puts the landing site just inside the left-hand edge of the image toward the middle. Compare the HiRISE image: In both of them there's a depressed area with a seed/diamond-shaped crater in it to the northeast, and Curiosity is just a little southwest of that. |

Tried matching up the full MARDI frame that was available and the HiRise image of the landing/impact sites with a larger context image of the overall landing/exploration area.

A larger version here 9.4mb This is awesome! Thanks! And thank you to all the rest for posting these incredible new images! |

I'm surprised the MARDI frame is so far over the dunes & mountain. I guess that's because the rover was still descending at an angle when those first frames were taken, right? -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Where did you wget them from? It looks like all the images are not yet showing up on the Sol 0 raws page. But you can get them by going here and adding 1 to the number ending at "I1_DXXX.jpg" edit: looks like it doesn't start getting interesting until frame 26, just to save anyone time who wants to do this. |

As I've done with past missions, I'm planning to produce some web pages that will help me and you browse these data sets better. I do this through manipulating the source html of the web pages in Excel, a process that would no doubt cause all the real programmers here to cackle with derision. Anyway, I'm wondering what form these pages should take that would be most useful for people.
As a start, here's an Excel file containing URLs and timestamps of all MARDI frames downlinked to date, including the 18 full res ones. (Note: change the extension from .zip to .xlsx in order to open)

Where did you wget them from? From here: http://mars.jpl.nasa.gov/msl/multimedia/raw/?s=0 (scroll to bottom). When I was downloading them they all were loaded on the server but not linked. Now I can see that they linked most of the files. The file name goes from 0000MD9999000001I1_DXXX.jpg to at least (did not check max number) 0000MD9999001442I1_DXXX.jpg -------------------- Polish space portal covering up-to-date space news: www.kosmonauta.net

It looks like the combination of Bayer issues and jpeg compression is producing artifacts, or something like that. google for "interline image sensor smear". Only likely to be an issue for very short exposure times. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

I was going to wait until the full frame images to do this, but here is my take on the MARDI thumbnail video. The audio timing with the MARDI images is pretty crude, but I think I got pretty close .

As more and more MARDI images come down I keep seeing this bright patch come and go. At first I thought it might be some random artifact or something of processing but it moves, disappears and reappears in many of the frames. Anyone have any ideas? High altitude ice particles reflecting the sun? Strangely, it seems to follow the heat shield as it falls away, then it disappears out of frame and comes back after the heat shield is no longer resolvable. Strange.
Lastly, I just want to say how great the color images are looking. Maybe it is just my imagination but the soil here looks far more intriguing than elsewhere we've seen insofar. -------------------- |

Been meaning to de-lurk for a few days now just to say how awesome this all is, but to be honest I'm still pretty speechless.
Anyway, here is my humble contribution MARDI image (http://mars.jpl.nasa.gov/msl-raw-images/msss/00000/mrdi/0000MD9999000512E1_DXXX.jpg), processed to bring out the landing site features a bit better. The rover is shown roughly to scale by the green rectangle in the centre. Looks like there might be an area of exposed layered 'bedrock' about 100m to the south. |

As others have pointed out this is the opposition highlight and in fact it is also obvious in images obtained on the ground. It's particularly obvious in the Navcam panorama - the brightest parts of the panorama are near the mast's shadow. |

Does it make sense that the sun would be behind the downward-pointing camera? -------------------- |

Well, MARDI has a wide field of view (90 degrees) and wasn't always pointed exactly down (Curiosity dangling a bit below the parachute plus the fact that it wasn't falling straight down - there was a horizontal component as well). |

On the chute the spacecraft (and the camera) wasn't pointing down, it was pointing more or less in the anti-sun direction. It only goes vertical later in the descent. The MARDI FOV is 71x53 degrees. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

The full EDL data is only going to come down in a few weeks, but since I'm impatient, I decided to try to map the field of view shown in the MARDI thumbnails to the underlying Martian terrain. This is very, very rough and there are numerous problems with it, but I suppose someone might find it mildly interesting.
The thumbnails were obtained from the raw images section of the NASA-JPL site and have not been corrected either for distortion or projection. Looking back I suppose I could have tried to split out the video that was released with distortion-corrected frames, though those would have additional compression artifacts. There's a lot of jitter in the frames. At one point I tried to smooth out the movement of features, but this just resulted in ugly systematic errors creeping in, so I decided it was more honest to leave the jitter as an expression of the uncertainty involved. This mapping shows the field of view of the camera, so cannot be directly related to the vehicle's position without the IMU data and some of the movement seen will be the result of attitude adjustments. We can clearly see the final stage of Wrist Control Mode (the large turn made in the beginning). The movement to the east at 1:00 might be related to backshell separation, and I think the divert manouevre probably starts at 1:15. I'm not sure what caused the final movement beginning around 1:38, possibly an attitude adjustment. This, of course, is all speculation. www.youtube.com/watch?v=gnUGUBzEO5Q |

I'm interested to know which frame of MARDI video would be the most urgent to download from Curiosity in order to help planning the begining of the route.
The frames can be blured by the movments during descent but pending they are looking strait down and the max definition is achieved, I was thinking of the following: 1- when quality equal HirIse (2 kms altitude) 2- twice better (1.320 km altitude) 3- 3 times better (660m altitude) I then calculate the FOV and get this: 1- 2400m x 1800m (it's what I found here: http://msl-scicorner.jpl.nasa.gov/Instruments/MARDI/) 2- 1584m x 1188m 3- 792m x 984m I'm wondering what do you think about this? My opinion is that, with such FOV, the terrain around where we landed look so benign that I don't think MARDI pictures will be of any (real) help for route planning to get to the base of Mt Sharp. Nevertheless MARDI will help for, say, the first 500m. -------------------- |

Nevertheless MARDI will help for, say, the first 500m. You can gauge which MARDI image has the spatial resolution you are looking for by comparing easily discernible features and compare their size to HiRISE. There might be some distortion due to vehicle attitude, but you should be mostly OK. Looking at HiRISE and MARDI I could not find anything weird except a tiny, easily avoidable, scarp at about 200 m to the east of the rover. Slopes are pretty benign in this neighborhood as well.

So, they said they're going to get the rest of the full-res MARDI pictures back this Sol? I'm really, really looking forward to seeing the entire descent film in high-res.
One thing, though. At least in the thumbnail version of the film, it was not extremely obvious what camera movements corresponded with major events, such as release from backshell, avoidance maneuver, etc. Does anyone have any ideas on how the full-res movie could be annotated to indicate these landmarks? -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Well, seeing a few full-res frames showing up in the MARDI collection from Sol 0 on the raw images pages. I checked last night and only found the one full-res image, of the heat shield shortly after release, that's been there for about a week. I just found two more full-res images, and more seem to be posting as we speak (after I found the first new one, I refreshed and the positions of the images changed, showing addition of new images, and then I found a second new one).
-the other Doug Quick edit -- now there are at least four new full-res pics, more coming in. Links to a few of them: http://mars.jpl.nasa.gov/msl-raw-images/ms...0124E1_DXXX.jpg http://mars.jpl.nasa.gov/msl-raw-images/ms...0200E1_DXXX.jpg http://mars.jpl.nasa.gov/msl-raw-images/ms...0256E1_DXXX.jpg -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

That's what I thought Mike Malin said, too, but what I *thought* I heard early in the telecon was "we're going to be getting the rest of those pictures out of the camera today." I definitely could have mis-heard, or the speaker could have mis-spoken. But I do note that high-res MARDI images are beginning to flow into the raw images page. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Out of the camera doesn't mean on the ground. They have to be pulled from the cameras own memory to the rover before getting downlinked.
And are you sure they were talking about MARDI and not the rest of the MastCam mosaic? |
