Replying to: <DIV CLASS='Discussion_PostQuote'>Does anybody know what those weird raw images are? They look overexposed or something. Are they calibration images? Posted by lucaspf</DIV>Good images that went bad during Phoenix -> orbiter (Odyssey or MRO) transmission, maybe? Depending on the compression technique, a few bad bytes might render the image unrecognizable.

Replying to: <DIV CLASS='Discussion_PostQuote'>Probably because:1) Many years ago, Phoenix was designed to land at the equator.</DIV>No.  While the base spacecraft was originally a near-equatorial lander (probably Meridiani) this was based on the MPL spacecraft, which was designed to land near the south pole.  The point was the MPL, Mars Sureyor were designed to be cheap RTG, this rules out an RTG.  They were also designed to achieve their goals in a short period of time, making an RTG unnecessary.  Since then we have learned that solar panels are self cleaning over the long term on Mars, rendering RTGs unnecessary for some longer missions as well.Replying to: <DIV CLASS='Discussion_PostQuote'>2) American public is scared of the word "nuclear."

Scribblenotes: Dwayne (moderator) with more kudos to the U of Az LPL about great job. He's over the top, it's getting old fast. Peter Smith (Science PI): Sol 4. 360 degree panorama finished earlier than planned. Showed full pan in fisheye and sweep view. Digging Scene (National Park; i.e. area they won't touch in beginning) and area they will experiment with shown with rock sizes and labels for Features. Names based on Fairy Tales and Folk Legends. Features at left are Humpty Dumpty (and associated charachters and features). Toward center of workspace is "Sleepy Hollow", one of the between polygon troughs. (One of the right rocks is Ichabod, cool for me since I once was Ichabod Crane as a youthful trick or treater-MW)(Sleepy Hollow could be an early target? -MW) Matt Robinson, Robotic Arm SW Lead. Arm is unstowed, all 4 joints had to work for that to happen, so first part of checkout is good. All the readings look like the arm is performing as expected. Next few days further testing each joint. Animations and photos of undock process. Early priority before moving the arm a lot is asessing Vehicle stability. So far, only one pad has been photo'd, arm will do the rest. One image will have to be from under Phoenix, and at this point they don't even know if there's a rock under there. So methodical is how we do things. Jim from Canada (Meteorological Instruments) 2 days Hi -30C (-22F) Lo -80C (-112F) Pressure still 8.5 mb. Described how wind sensor works ("Wind sock shaped cylinder hanging by a thin thread. It aligns and deflects from verticle, allowing Wind measurements. Wind data not collected, instead measurements of dust in atmosphere, Dust is being lifted to 3 km. Barry Goldstein: Talked about anomoly's (including MRO UHF issue). We keep you informed of everything, but it has gone much smoother than expected. None of these events have stressed the team at all, better than expected. (implied: So don't panic at every little glitch. They're expected-MW) Lots of praise for folks that have uprooted themselves to Arizona for the duration of the mission. Now in Charachterization phase. Engineering (Solar, Arm, Cameras, etc) all look good. Next is full payload checkout. Questions (almost half were from The Planetary Society, one in person and the other on phone). First target (from TPS). A: Peter: no not yet. Matt, TEGA is first destination for surface materials. Q: (from TPS) Source of local rocks? A: (Peter) {chuckle} right now we're working on where they are. And maybe why are they where they are. Does the ground circulate (like polar landscapes on earth that produce polygons) and does that leave a pattern in location? (Sky and Tel) A: (Peter)Rocks seem to be flat, and brighter than the surface. Make of that what you will for now. There was an SDC question... What time is it on Mars. A: currently about 2 hours later than Tucson time. MW <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters. Monsters from the Id.

I’m a bit intrigued about that little weather sensor.  I’d assume an anemometer would be less effective as the air pressure is so low and there is little means of calibrating it once it gets to the surface.    The windsock is pretty neat; more like an anemoscope.  Not only will it tell you the wind direction but, via deflection, the wind speed.  I have to assume you’d need to know the barometric pressure at the time of measurement?  You’d certainly have to know the density of the air to imply its speed via deflection?

efron_24 · May 29, 2008

It would be nice if we knew the temperatures at the sites of the Rovers.So we could compare.Btw Is 3km for the dust a surprise, or is it what they expected  <div class="Discussion_UserSignature"> </div>

It's nice to get some scale perception on those rocks, they are smaller than I would have assumed.Posted by lucaspf</DIV>Replying to: <DIV CLASS='Discussion_PostQuote'>Greetinsg from a fellow rock head!  What do yous ee in thee images?On the scale issue, the panorama has marked on it degrees above and below the horizontaal.  It's worth remembering that objects at -10 degrees are 10 m away, -20 ~5 m, -30 ~3 m, -45 ~2 m.Those rocks really are small,  Pebbles, mostly.Jon Posted by jonclarke</DIV>Hi Jon & Lucas,Image below (also posted several pages back now).http://www.photodump.com/Anonymous http://www.photodump.com/Anonymous/Various%20rocks%20sol%202.html <img src="http://sitelife.space.com/ver1.0/Content/images/store/0/12/50bbffbe-349a-4b83-bc11-5da0d7477a60.Medium.jpg" alt="" /> I'm not too sure about the statement about the lack of insight into some of the rocks.Above are at least two pieces of basalt, complete with vesicles & are grey. Obvious in the extreme, in my eye. There is one in the Phoenix image above that is quite similar to one I have here decorating the top of the television, I bought back from Tenerife, Canary Islands. Same type of rock, but from very different places & planets.My question is this. The flat topped rocks, many appear to display layering & are lighter toned. To me at the moment, they appear sedimentary, though they could be very low silica lavas (less the 50%, making the original very fluid), but their colours seem to rule that out.Hopefully the MRO HiRISE will case out the entire area, including Heimdall Crater & the high resolution Phoenix Lander colour images of the southern horizon with the hills, will certainly help. 1). Is Hiemdall Crater the result of an impact on either volcanic or sedimentary rock?2). Are the hills on the southern horizon as seen by Phoenix volcanic or sedimentary?3). What is the source of the basalt at the Phoenix Landing site?Lots & lots & lots of questions. Only got between 90 to 150 sols though, before Phoenix freezes up in the cryonically cold & increasingly dark conditions at that location.Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world. It was extremely large with respect to the overall size of Io and crescent shaped. It seemed unbelievable that something that big had not been visible before". Linda Morabito on discovering that the Jupiter moon Io was volcanically active.
