RE: [meteorite-list] 'Serious Anomaly' Silences Mars Spirit Rover
Wouldn't it be funny if it has fallen into a puddle... I did notice that around the time spirit went down, the Magnetometer networks were showing increased local activity, i.e solar auroral activity. Looking at www.spaceweather.com it appears that there have been a couple of decent sized flares/CME (Coronal mass ejections) recently, maybe this is what damaged Spirit?

[meteorite-list] Mars Express Sees Its First Water - Scientific Results
http://www.esa.int/export/SPECIALS/Mars_Express/SEM8ZB474OD_0.html N° 06-2004 - Paris, 23 January 2004 Mars Express sees its first water - scientific results European Space Agency Mars Express, ESA's first mission to Mars, will reach its final orbit on 28 January. It has already been producing stunning results since its first instrument was switched on, on 5 January. The significance of the first data was emphasised by the scientists at a European press conference today at ESA's Space Operations Centre, Darmstadt, Germany. I did not expect to be able to gather together - just one month after the Mars Orbit Insertion on 25 December - so many happy scientists eager to present their first results, said Professor David Southwood, ESA Director of Science. One of the main targets of the Mars Express mission is to discover the presence of water in one of its chemical states. Through the initial mapping of the south polar cap on 18 January, OMEGA, the combined camera and infrared spectrometer, has already revealed the presence of water ice and carbon dioxide ice. This information was confirmed by the PFS, a new high-resolution spectrometer of unprecedented accuracy. The first PFS data also show that the carbon oxide distribution is different in the northern and southern hemispheres of Mars. The MaRS instrument, a sophisticated radio transmitter and receiver, emitted a first signal successfully on 21 January that was received on Earth through a 70-metre antenna in Australia after it was reflected and scattered from the surface of Mars. This new measurement technique allows the detection of the chemical composition of the Mars atmosphere, ionosphere and surface. ASPERA, a plasma and energetic neutral atoms analyser, is aiming to answer the fundamental question of whether solar wind erosion led to the present lack of water on Mars. The preliminary results show a difference in the characteristics between the impact of the solar wind area and the measurement made in the tail of Mars. Another exciting experiment was run by the SPICAM instrument (an ultraviolet and infrared spectrometer) during the first star occultation ever made at Mars. It has simultaneously measured the distribution of ozone and water vapour, which has never been done before, revealing that there is more water vapour where there is less ozone. ESA also presented astonishing pictures produced with the High Resolution Stereo Camera (HRSC) . They represent the outcome of 1.87 million km2 of Martian surface coverage, and about 100 gigabytes of processed data. This camera was also able to make the longest swath (up to 4000 km) and largest area in combination with high resolution ever taken in the exploration of the Solar System. This made it possible to create an impressive picture 24 metres long by 1.3 metre high, which was carried through the conference room at the end of the press event by a group of 10-year-old children. Mrs Edelgard Bulmahn, German Minister for Research and Education, who is also chair of the ESA Council at ministerial level, said at the press conference: Europe can be proud of this mission: Mars Express is an enormous success for the European space programme.

[meteorite-list] Russell's meteorites - presentation
Hi all, Firstly, apologies for not telling you all about this sooner; it's just been a crazy week with all the drama on and around Mars, my phone's never stopped ringing with schools asking me to give them talks featuring all the latest news from Beagle, Spirit, Opportunity and Mars Express. But finally, a week after the big day, I have a chance to tell you about the presentation to Russell of his meteorites last Friday afternoon. It was a wonderful afternoon. Armed with a bag bulging full of meteorites from the people on this List I arrived at the school an hour before the arranged 1pm visit of local press reporter and photographer, and who was the first person I saw in the school lobby? Russell himself. And it was quite a shock. Last time I saw him, in November, he looked very ill indeed - pale skin, slumped, very ill looking... but the *new* Russell is a picture of health in comparison - much healthier complexion, eyes much brighter and, best of all, a huge, beaming smile :-) Still in his wheelchair, but much, much happier, and he greeted me with a cheery hello and big grin when he saw the bag slung over my shoulder. We had a quick chat, then I went to wait in the staff room with the teachers. All twelve teachers in the school are female, so it wasn't too much of an ordeal waiting... :-) Eventually the photographer arrived, and we did a photo-shoot for the local papers - the school, and Russell's parents, having been very keen to get Russell in the paper as part of his therapy, cheering him up and encouraging his recovery etc - which went very, very well. Russell was a real trouper, holding up meteorites for the camera and beaming proudly and happily even tho he was getting rather tired by the end of it. The photographer actually had him *laughing* as he took his pics, joined by myself for a couple, then a couple of his friends, and finally the Head Teacher (US = Principal) who was literally having to hold back tears she was so moved by it all, and by Russell's changed spirit. Then my reporter friend Andrea arrived, and interviewed Russell for ten minutes or so - and all the time he refused to put down the meteorites, I'm sure he's still holding them right now... With all the media stuff done, we - that's myself, Russell, the head teacher and other teachers - went up the corridor and into a large nearby classroom so I could speak to the rest of the kids in the school, explaining to them how all these amazing meteorites had come in for Russell from all around the world. He sat on the sidelines, still smiling, still clutching his precious gifts, and at the end all the other kids gave him a huge round of applause and crowded round him to look at his new treasures, leaving one of the red-eyed teachers to mouth me a silent "thank you"... ...but that thank you was appropriate for all the people who sent meteorites to Russell, not for me, all I did was take in the mail. So, thanks guys, good job. In the past week, Russell's story has been featured in several local papers, which has, I'm told, cheered him up and energised him even more. If anyone would like to see a copy of the photo (just excuse my ugly mug in it, I asked them NOT to use one of me, keep it just about Russell, but I don't know, maybe the others didn't come out or something... ) and the article which accompanied it, please email me and I'll send copies as attachments. I can't put them on my website because it's playing up, but I'll happily pass on scans to anyone who wants to see them. The head teacher has asked me to pass on her personal thanks and best wishes to everyone who was so generous with their time and meteorite collections, too. I passed on the letters to Russell too, and I know he is planning to write to everyone who sent him something, but don't hold your breath, he's still ill and his days are rather full with various treatments, therapies etc... Just keep an eye on your (e) mail boxes, one day there'll be a note there, you'll see. So, there you go. Russell has his meteorites, and everyone who sent one should feel very, very proud that they helped make a very sick little boy smile again. Thanks everyone, Stu P.S. On a more personal note, people who've generously sent me samples and specimens for my own Outreach work will, I hope, be pleased to hear that they are all on display in a local museum right now, as build-up publicity for my astronomical society's huge "MARS DAY" exhibition event next Saturday.

[meteorite-list] SwRI Suborbital Science Payload Gets The Goods on Mercury, Searches for Vulcanoids
SwRI suborbital science payload gets the goods on Mercury, searches for Vulcanoids Southwest Research Institute January 23, 2004 A new major scientific payload flew in space last week after launching aboard a NASA suborbital Black Brant rocket. The payload, consisting of a telescope/spectrometer combination and an image-intensified imaging system, successfully explored the ultraviolet spectrum of the planet Mercury and also searched for the long-sought belt of small bodies called Vulcanoids that may lie even closer to the Sun than Mercury. Southwest Research Institute (SwRI) provided the payload and is responsible for data analysis. The rocket flew a textbook flight and got the goods on our calibration star (Zeta Ophiuchus), Mercury and the Moon -- everything in the flight plan, says Dr. Alan Stern, mission principal investigator and director of the SwRI Space Studies Department. The secondary payload, the so-called VULCAM (Vulcanoid camera) imager, also worked like a champ, searching for Vulcanoids while the spectrograph studied Mercury itself. The payload's main instrument is a large (almost 500 pound), highly sensitive, ultraviolet spectrograph designed to observe objects too close to the Sun for the Hubble Space Telescope and other orbital instruments to view. The new SwRI instrument has been dubbed Big Dog by its inventors, owing to the large size of the payload. We built Big Dog specifically to fill a niche -- exploring objects in the deep inner solar system, explains SwRI's Dr. David Slater, project scientist for the instrument and leader of the field team that took the payload to White Sands for the launch preparations and flight. This flight proves we can now examine objects -- like Venus, Mercury and bright comets close to the Sun -- that are normally lost in the Sun's glare to orbiting telescopes, on a routine basis. This is a real asset for planetary astronomy and for certain kinds of astrophysics as well. VULCAM scientist Dr. Dan Durda, also of SwRI, added, VULCAM is a derivative of an imaging instrument we have flown many times on F-18 aircraft, but which has the potential to become an even more powerful tool for searching for Vulcanoids from 260+ kilometer (165+ mile) altitudes that NASA suborbital missions can reach. VULCAM also performed flawlessly. Never before in history has it been possible to obtain an ultraviolet spectrum of Mercury, says Stern. With the data gathered last week, we expect to reveal new details about this mysterious inner planet's surface composition and, hopefully, to help the upcoming NASA MESSENGER mission to Mercury plan its ultraviolet observations. Primary funding for this mission came from NASA, with supplemental support from The Planetary Society. The NASA Wallops Island Flight Facility managed the mission and provided both the launch vehicle and the pointing, telemetry and recovery systems required to support the flight. The Center for Astrophysics and Space Astronomy at the University of Colorado at Boulder also collaborated on the mission. Vulcanoids are a hypothesized population of small asteroids that is exceedingly difficult to observe from the ground because of its proximity to the Sun. Researchers have made previous ground-based searches for Vulcanoids during total solar eclipses, during the brief twilight period after sunset before the Vulcanoids themselves set or just before sunrise after the Vulcanoids have peaked above the horizon.

[meteorite-list] The Sky Is The Limit
http://marsrovers.jpl.nasa.gov/spotlight/spirit/a10_20040120.html The Sky Is The Limit Jet Propulsion Laboratory January 20, 2004 Believe it or not, some of the scientists on the Mars Exploration Rover Science team don't really care too much about rocks - or for that matter anything on the surface of Mars. They have higher ambitions. Their passion lies in the skies - the martian skies - and, from the hazy glow of the atmosphere, they pull precious pieces of information. Two of these sky gazers are Mike Wolff and Mike Smith. They are brimming with energy because, in the next few sols, Spirit will be doing more atmospheric study than she's done since landing. It's a bit of a running joke that the atmospheric team gets left out, laughs the jovial pair. Let's be honest, this is predominantly a geology mission - water and rocks. The atmospheric team is also a little outnumbered, There are very few of us atmospheric scientists who want to spend Spirit's time looking at the sky. The vast majority of the team wants to look at the ground. All the joking aside, Mike and Mike know the importance of good atmospheric data, explaining that it is crucial for ground-lookers to know what they are seeing. For instance, scientists study the light that is reflected from each surface to determine what minerals are in the rocks on Mars. In order to make accurate calculations, they must understand the atmosphere through which the light traveled before reaching the rocks and reflecting back. They DO need us, smiles Wolff. Our team provides information about the amount of dust and water vapor in the atmosphere, allowing other teams to make sense of what they're seeing. Beyond a supportive role, the atmospheric team is trying to answer big questions about the climate on Mars that will help all future Mars exploration. We need a complete understanding of the environment we're working with - what conditions do we need to prep for? How much dust is there, and will it interfere with machinery? What are the temperature extremes that can interfere with the successful operation of instruments? The more we understand the weather on Mars, the more likely it is that a Mars mission will have success, explains Smith in a serious moment. The term weather on Mars can mean a lot of different things, but the atmospheric team is harvesting hypotheses from four main elements: air temperature, water-ice clouds, water vapor, and dust. Air Temperature Using the Mini-TES instrument, the atmospheric team can determine the temperature of the Martian atmosphere at various heights from the surface to about two kilometers (about 1.2 miles) above the surface. Orbiters and previous landed missions could not provide this near-surface information as precisely as Mini-TES can, and both Mikes are excited to have it. All the major weather systems on Mars are affected by this lower area, so it's really fantastic to be seeing this detailed data, says Smith. These temperature readings assist engineers as they assess the rovers' heath. Engineers need to know if things are heating up on Mars so that they can prepare to keep the rover cool. Water Vapor Water-vapor is a fancy atmospheric term for humidity, jokes Wolff. If you've ever been in the south in the summer, you know what water vapor is. Mars does have some water vapor, but not much. In fact, Earth has about 10,000 times more water in its atmosphere than Mars does. The amount of water vapor in the atmosphere is important to scientists because it is a key part of the current climate and potentially gives clues about the distribution of water under the surface. Water-Ice Clouds Like the high, wispy, cirrus clouds we see here on earth, water vapor in Mars' atmosphere freezes and forms into cirrus-like clouds on Mars. By studying the quantity, location, and longevity of these clouds, scientists can better understand how water is exchanged between the martian surface and atmosphere. While orbiters have provided us with many great images of cloud-cover on Mars, they are limited by the time of day of their orbit and can only reveal what the clouds look like in a particular spot at a particular time. With Spirit and Opportunity we can watch the clouds throughout the day and monitor how they change, explains Wolff. Dust Scientists operating a rover on the surface of Mars have one major concern when it comes to dust: accumulation. The planet is covered in the fine, powder-like material and daily winds blow it across the planet forming dunes and ripples. Too much of this dust on the solar panels could cause them to work less efficiently. The atmospheric team monitors how much dust is in the atmosphere and helps the engineering team evaluate the performance of Spirit's solar panels. During the mission, Spirit will point its Panoramic camera and Mini-TES instruments towards the sky, giving the atmospheric team another chance to shine. Most of the

[meteorite-list] Opportunity Closes in on the Red Planet
http://space.com/missionlaunches/opportunity_update_040123.html Opportunity Closes in on the Red Planet By Leonard David space.com 23 January 2004 PASADENA, Calif. -- Early Jan. 25, at about 12:05 a.m. EST, NASA's second Mars Exploration Rover -- Opportunity -- will arrive on Mars. It's headed for a region known as Meridiani Planum, halfway around the planet from where its sister robot, the Spirit rover now resides. What Opportunity might find at that landing site could be the geological mother lode at Mars that scientists seek -- a type of mineral that cries out: Water was here! As was the case three weeks ago, engineers are again faced with risk, worry, and high anxiety in getting another robot successfully down on Mars. One thing for sure: It doesn't get any easier the second time around. Good dose of edginess I am almost as nervous as I was for Spirit, admitted Rob Manning, Mars Exploration Rover (MER) Entry, Descent and Landing Lead at JPL. Even though Meridiani is an easier landing site in some respects - less winds, less slopes, and the rocks aren't as bad. I'm going to be almost as nervous, he told SPACE.com . In reconstructing how Spirit made it down at Gusev Crater, Manning has reason to retain a good dose of edginess. We had a wild day in landing Spirit, Manning said. An unexpectedly large wind gust played havoc with the spacecraft's approach and touchdown at Gusev. That burst of wind pushed Spirit's parachute and other landing gear in a horizontal direction toward a crater. An inertial measurement unit, computer software, special camera gear, and small rockets onboard Spirit worked in concert to counter what could have been a deadly drift into the walls of the crater -- all within a handful of seconds, Manning noted. I don't know if we would have been toast. On the other hand, it's an experiment I don't think I would want to perform, Manning added. Once cut free from its parachute, retro-rocket engines, and long bridle, the set of airbags with the Spirit rover tucked inside fell onto Mars from a height of about 31 feet (9.5 meters). The airbags bounced 28 times across the martian landscape before coming to a full stop. Glue gun and duct tape At the end of the day, Spirit's safe and sound landing comes down to one engineering rule of thumb: margin. Margin equates to elbow room. There is a delicate balance between margins and how close-to-the-edge engineers feel is tolerable. But then add in the vagaries of the Mars environment, well, those uncertainties can give you a bad day. From what I see, we have a lot of margin. We are confident that we made the right design choices in our rover landing system to make it reliable, Manning said. But you never know. If I could land a thousand of these things, then I could tell you. We're still in the infant stages of this stuff. Lessons learned from getting Spirit down and dirty on Mars are being applied to the landing of Opportunity. For example, Opportunity's parachute is to be deployed higher and five seconds earlier than planned over Meridiani Planum. Secondly, gas generators to inflate the airbag landing system have been tweaked to reduce their warm-up time during the plummet toward Mars' surface. Opportunity's landing system is good to go, Manning said. Our mission is not to do engineering, although it's fun, exciting, and a lot of work. It doesn't matter if you took a glue gun and duct tape to get to Mars. As long as you get there safely - and we get good science for the mission - that's the most important thing, he explained. Colorful territory At Meridiani Planum, the Opportunity rover becomes a stranger in a strange land. This site will truly be an alien landscape. It will not look like anywhere we have been before on Mars, said James Rice, a Mars Exploration Rover scientist from the Arizona State University in Tempe. Rice said he expects Opportunity to drop into colorful territory, perhaps a deeper, darker reddish brown with splashes of gray. All that pesky bright dust that we are familiar with will be absent, Rice told SPACE.com . The chances of encountering fantastic layered sediments will be much higher in Meridiani than at Gusev Crater, he explained. These layers may be visible in small mesas and buttes. Moreover, the landscape appears to have been stripped by the wind. There will also be far fewer rocks than at Gusev, roughly half the rock abundance seen in the images returned by Spirit, Rice said. We may also see dune forms and small impact craters depending on where we put down in the landing ellipse, Rice added. Gray hematite Opportunity's targeted landing area is an ellipse about 53 miles (85 kilometers) long and 6.8 miles (11 kilometers) wide. This zone is within a large region near the planet's arbitrarily designated prime meridian, or line of zero longitude. Planum means plains. So the name suits the territory. Meridiani Planum is one of the smoothest, flattest places

[meteorite-list] Spirit Remains In 'Critical' Condition
http://www.spaceflightnow.com/mars/mera/040123recovery.html Spirit remains in 'critical' condition BY WILLIAM HARWOOD STORY WRITTEN FOR CBS NEWS SPACE PLACE USED WITH PERMISSION January 23, 2004 The crippled Spirit rover remains in critical condition on the surface of Mars, engineers said today, the victim of ongoing electronic seizures that have caused its central computer to reboot itself more than 60 times over the past two days. Engineers successfully coaxed the rover to beam back limited engineering data during two brief communications sessions and they were relieved to discover the spacecraft's power system was providing the necessary life support. But Spirit's state of mind was clearly - and unusually - different in both sessions, ruling out any simple explanations for what might have gone wrong. We have a serious problem, said project manager Pete Theisinger. The fact that we've got a vehicle that we believe is stable for an extensive period of time will give us time to work that problem. We can command it to talk to us and even though we get perhaps limited information, we do get good information and that helps us work through the problem. I expect that we will get functionality back out of this rover. I think the chances that it will be perfect again, I would think, are not good. The chances that it will not work at all, I think are also low. I think we're somewhere in that broad middle and we need to understand the problem to find out exactly where we are. Spirit went on the blink Wednesday as it was carrying out a procedure to calibrate drive motors used by its thermal emission spectrometer. Prior to that moment, everything was operating normally. But some event, possibly a hardware failure of some sort, threw the rover's electronic brain for a loop. Since then, the spacecraft has been in a state of limbo, responding in unusual fashion to anxious flight controllers. This morning, we sent an early beep to the spacecraft and did not get a response, Theisinger said. As we were preparing to send a second, the spacecraft talked to us. We got very fractional frames and then moved very quickly to ask it to speak to us for 30 minutes at 120 bits per second. We got 20 minutes of transmission in that occasion, which was a single frame of engineering data repeated. Then we repeated that full sequence of events and we got about 15 minutes of engineering data at 120 bits per second where the frames were updated for 15 minutes and then for the second 15 minutes we had nothing but fill data. He said Spirit has been in a processor reset loop of some type, mostly since Wednesday, we believe, where the processor wakes up, loads the flight software, uncovers a condition that would cause it to reset. But the processor doesn't do that immediately. It waits for a period of time - at the beginning of the day it waits for 15 minutes twice and then for the rest of the day it waits for an hour - and then it resets and comes back up. Complicating the work to track down the problem, the indications we have on two occasions is that the thing that causes the reset is not always perceived to be the same, Theisinger said. We are confused by that, but that's the facts as we presume them to be right now. The reset sequence, similar to repeatedly unplugging one's personal computer and forcing it to restart, began Wednesday morning on Mars when a calibration of the spectrometer motors ended prematurely. An anomaly team has been formed to study the telemetry and to decide what readings to request from Spirit to help narrow down the range of possible failures. I think we should expect that we will not be restoring functionality to Spirit for a significant period of time, Theisinger said, I think many days, perhaps a couple of weeks, even in the best of circumstances, from what we see today. In the meantime, he said, Spirit remains in critical condition. We do not know to what extent we can restore functionality to the system because we don't know what's broke, Theisinger said. We don't know what started this chain of events and I think, personally, that it's a sequence of things, and we don't know, therefore, the consequences of that. I think its difficult at this very preliminary stage to assume we did not have some type of hardware event that caused this to start and therefore, we don't know to what extent we can work around that hardware event and to what extent we can get the software to ignore that hardware event if that's what we eventually have to do. We've got a long way to go here with the patient in intensive care. But we have been able to establish that we can command it, and we have been able to establish that it can give us information and we have been able to establish that the power system is good and we're thermally OK and those are all very, very important pieces of information. We are a long, long way from being done here, but we do have serious problems and our ability to

I think we should expect that we will not be restoring functionality to Spirit for a significant period of time, Theisinger said, I think many days, perhaps a couple of weeks, even in the best of circumstances, from what we see today. In the meantime, he said, Spirit remains in critical condition. We do not know to what extent we can restore functionality to the system because we don't know what's broke, Theisinger said. We don't know what started this chain of events and I think, personally, that it's a sequence of things, and we don't know, therefore, the consequences of that. I think its difficult at this very preliminary stage to assume we did not have some type of hardware event that caused this to start and therefore, we don't know to what extent we can work around that hardware event and to what extent we can get the software to ignore that hardware event if that's what we
[meteorite-list] Mars Express Commissioning and Early Results
http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=34487 Mars Express Commissioning and Early Results European Space Agency 23 Jan 2004 Overall Mission Status The Mars Express orbiter was successfully inserted into orbit around Mars on 25 December 2003. Since then several manoeuvres have been performed using the spacecraft?s main engine (plane turn manoeuvre and apocentre reductions) and several further manoeuvres will be performed, using the on-board thrusters, until the mapping orbit is reached on 28 January 2004. The Mars Express spacecraft has continued to show nominal performance over the past week with the payload and subsystems operating as expected. The spacecraft's main engine has been isolated as it will not be used anymore. The Beagle-2 lander was separated from the Mars Express orbiter on 19 December and is assumed to have landed in Isidis Planitia on 25 December. However, attempts to communicate with the lander have so far been unsuccessful. Meanwhile, the orbiter scientific payload commissioning has started and the payload instruments started returning their first scientific measurements from Mars orbit. During this early phase, mostly dedicated to instrument checkout and calibration, high-resolution stereo and colour images and high-resolution spectral measurements of the planet are being acquired. The radio science experiment has been obtaining its first scientific data from Mars (bistatic radar measurements), and the MARSIS radar, which is scheduled for deployment at the end of April 2004, will soon be conducting further checkout activities. The early orbits of Mars Express, until about mid-February 2004, represent the best opportunity for optimised observing conditions (illumination, targets of interest, distance to the Sun, lack of eclipses) and, therefore, maximum science return. The planning of the next payload commissioning activities and science operations are progressing nominally. Payload activity timelines are being prepared for the next few weeks, with the goal of optimising the scientific return while keeping within the limits of the power budget. Science Results 19 January 2004 HRSC The first science result showed the Valles Marineris canyon system in stunning detail. Valles Marineris is a giant canyon system stretching 4000 km across the surface of the planet. At its start and end it is 2 km deep and in the middle it is 7 km deep and 600 km wide. 23 January 2004 OMEGA Analysis of data acquired over the southern polar cap on 18 January has revealed the existence of trapped water ice along with carbon dioxide ice. PFS PFS data has shown that there is an inbalance to the distribution of carbon dioxide on Mars. HRSC HRSC has now imaged an area of the Martian surface covering 1.87 million km2. This corresponds to 100 Gigabytes of data! The camera images a single track up to 4000 km in length (roughly the size of the United States from coast to coast). A series of stunning images have been released revealing river channels, dust falling over a cliff edge and erosion features. SPICAM A unique measurement was made with SPICAM. By observing a star twice, once through the atmosphere and once with no atmosphere present, it was possible to analize the Martian atmosphere. This has enabled measurements to be made on the distribution of the ozone and water vapour revealing that there is more water vapour where there is less ozone. Orbit and Surface Coverage Information The orbit of the Mars Express spacecraft is very stable. Several more apocentre reduction manoeuvres will be conducted in order to reach the selected mapping orbit on 28 January. The early scientific planning is driven by the opportunity to take images and spectral measurements of a number of targets of interest under excellent observing conditions. The current observations cover a variety of essential Martian surface features and targets of interest: volcanic terrains, chaotic terrains near Valles Marineris, Isidis Planitia with the Beagle-2 landing site, and the Spirit landing site (Gusev Crater). Later on, once the mapping orbit is achieved, the focus of science data acquisition will be extended to global coverage, mosaic and map construction, and high-resolution imaging and spectral mapping of selected local surface targets.

RE: [meteorite-list] Spirit Remains In 'Critical' Condition
Hehe. Personally, I think that this reboot-loop is caused by a short-circuit somewhere. BTW - one of the astonishing findings of ESA is that Mars seems to be much warmer than thought. They expected -120°C to -30°C, but instead they found the temperature is +4°C. Don't know where this temperature was encountered, but if it's true, it seems that we have a LOT to learn about Mars (and that conditions are more favorable to former (or existing?) life than thought. I read somewhere that the orbit of Mars is much more changing over time than that of earth, and that Mars could have been much warmer a long time ago because of that.

We should expect we will not be restoring functionality to Spirit for a significant amount of time -- many days, perhaps two weeks -- even in the best of circumstances, said Peter Theisinger, rover project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spirit transmitted data to Earth today for the first time since early Wednesday. The information about the rover's status arrived during three sessions lasting 10 minutes, 20 minutes and 15 minutes. Engineers will be examining it overnight and developing a plan for obtaining more on Saturday morning. Spirit's flight software is not functioning normally. It appears to have rebooted the rover's computer more than 60 times in the past three days. A motor that moves a mirror for the rover's infrared spectrometer was partway through an operation when the problem arose, so the possibility of a mechanical problem with that hardware will be one theory investigated. We believe, based on everything we know now, we can sustain the current state of the spacecraft from a health standpoint for an indefinite amount of time, Theisinger said. That will give the team time to work on the problem.

Opportunity's landing site is on plains called Meridiani Planum within an Oklahoma-sized outcropping of gray hematite, a mineral that usually forms in the presence of water. Scientists plan to use the research instruments on Opportunity to determine whether the gray hematite layer comes from sediments of a long-gone ocean, from volcanic deposits altered by hot water, or from other ancient environmental conditions. Analysis of Spirit's descent through Mars' atmosphere for its landing at Gusev has contributed to a decision by flight controllers to program Opportunity to open its parachute higher than had been planned earlier, said JPL's Dr. Wayne Lee, chief engineer for development of the rover's descent and landing systems.

RE: [meteorite-list] Rover Team Readies For Second Landing While Trying to Mend Spirit
All, If I may...Spirit is still positioned in front of Adirondack. It was not hit by a meteorite, suffer a coronal mass ejection radiation event or any other type of external incident. Personal telecon w/JPL/MER managers has revealed that they DO NOT know what has happened and are trying through fault tree analysis coupled with engineering/health telemetry from Spirit to recreate the precipitating event using the almost one for one rover they have for a test bed. Power and thermal protection systems are currently nominal. JPL is trying to command Spirit to power down its computer and go into sleep mode which it has not done for the past several nights. This is causing Spirit to use more power than expected and is causing a drain on the batteries. The spacecraft is alive, being commanded from Earth and has sent back over 75MB of data today when Odyssey flew over. The team is trying to put the pieces together in such a way as to cause no harm to Spirit. They have plenty of time to analyze and fix this anomaly... Remember, every major spacecraft mission has had its glitches and our team is pretty darn good at solving them. Time and telemetry will tell.
