Above, Rover Spirit positions the RAT over the rock Adirondack. Below, a microscopic image of the rock. NASA/JPL did not say whether this image was taken after the RAT was used to brush the dust off Adirondack Thursday, or whether the image is after the RAT was used to grind below the surface of the rock (which was scheduled to happen today).

Mars Exploration Rover Mission StatusFebruary 5, 2004NASA's Opportunity rover drove about 3.5 meters (11 feet) early Thursday toward a rock outcrop in the wall of a small crater on Mars, and mission controllers plan to send it the rest of the way to the outcrop late Thursday. Opportunity's twin, Spirit, successfully reformatted its flash memory on Wednesday. Flash is a type of rewritable memory used in many electronic devices, such as digital cameras, to retain information even while power is off. Problems with the flash memory interfered with Spirit's operations from Jan. 22 until this week. Engineers prescribed the reformatting to prevent recurrence of the problem. On Thursday, Spirit's main assignment is to brush off an area on the rock nicknamed "Adirondack" to prepare for a dust-free examination of its surface. On Friday, controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., plan to have Spirit grind off a small patch of Adirondack’s outer surface and inspect the rock's interior. Spirit may start driving over the weekend toward a crater about 250 meters (about 270 yards) to the northeast. Update: As I suspected yesterday ( see comments), the micro image above is after the brush-off, not after using the RAT to grind Adirondack. See http://marsrovers.jpl.nasa.gov/mission/status.html or the pictures and captions here: http://marsrovers.jpl.nasa.gov/. You can't tell, but grinding either took place late Friday, or will be done today (I don't think the PR guys who do most of the webpage stuff work late on Fridays, and I'm not sure about weekends either...) Meanwhile, look for a post up above about Opportunity looking over the bedrock they've named "Snout"... posted by Gary Williams at 2:58 PM | link | via O'Reilly Sucks

Opportunity Passes Her Driver's Test! sol 12, Feb 05, 2004 "Just like you would want to perfect your parallel parking abilities before trying to make it to an appointment on a tight schedule in a big city, engineers tested Opportunity's ability to maneuver on Mars on sol 12, which ended Thursday. She passed with flying colors!" reported Mark Powell, Science Downlink Coordinator. Engineers commanded Opportunity to do a little dance, making three arcs -- two to the left and one to the right. Opportunity then did a 30-degree turn in place where you can see the most radical track curves in the image. For its grand finale drive, Opportunity proceeded straight for 1.8 meters (5.9 feet), completing a total traverse of 3.54 meters (10.6 feet). The plan for sol 13 is to do a 1.1 meter (3.6 feet) drive straight toward the outcrop and take some more pancam and mini-TES instrument images of the outcrop area.Scientists have decided to wait to trench for a few days until they can drive to an area with a higher concentration of hematite. Spirit Rover Status: Spirit's Surgery Successful! Spirit woke up earlier than normal today at 6 a.m. local Mars time to the tune of Surfari's "Wipe Out" in order to prepare for its memory "surgery." Engineers ended the memory overload problem today by erasing and reformatting the flash file system. The operation was a success, and the patient is doing very well. Spirit is scheduled to brush off any loose dust on the rock Adirondack tomorrow to prepare for the first exciting grinding event with the rock abrasion tool this weekend, which may reveal historical clues about the rock's formation and the past environment on Mars. posted by Gary Williams at 8:21 PM | link | via Uninstalled Michael O'Connor Clarke's New ServiceMy friend Michael is now offering a new service:![]() Oh, and in case you were wondering...

This map of a portion of the small crater currently encircling the Mars Exploration Rover Opportunity shows where crystalline hematite resides. Red and orange patches indicate high levels of the iron-bearing mineral, while blue and green denote low levels. The northeastern rock outcropping lining the rim of the crater does not appear to contain much hematite. Also lacking hematite are the rover's airbag bounce marks. This image consists of data from Opportunity's miniature thermal emission spectrometer superimposed on an image taken by the rover's panoramic camera. Image credit: NASA/JPL/Arizona State University/Cornell Opportunity Sees Tiny Spheres In Martian SoilNASA's Opportunity has examined its first patch of soil in the small crater where the rover landed on Mars and found strikingly spherical pebbles among the mix of particles there."There are features in this soil unlike anything ever seen on Mars before," said Dr. Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for the science instruments on the two Mars Exploration Rovers. For better understanding of the soil, mission controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., plan to use Opportunity's wheels later this week to scoop a trench to expose deeper material. One front wheel will rotate to dig the hole while the other five wheels hold still. The spherical particles appear in new pictures from Opportunity's microscopic imager, the last of 20 cameras to be used on the two rover missions. Other particles in the image have jagged shapes. "The variety of shapes and colors indicates we're having particles brought in from a variety of sources," said Dr. Ken Herkenhoff of the U.S. Geological Survey's Astrogeology Team, Flagstaff, Ariz. The shapes by themselves don't reveal the particles' origin with certainty. "A number of straightforward geological processes can yield round shapes," said Dr. Hap McSween, a rover science team member from the University of Tennessee, Knoxville. They include accretion under water, but apparent pores in the particles make alternative possibilities of meteor impacts or volcanic eruptions more likely origins, he said. A new mineral map of Opportunity's surroundings, the first ever done from the surface of another planet, shows that concentrations of coarse-grained hematite vary in different parts of the crater. The soil patch in the new microscopic images is in an area low in hematite. The map shows higher hematite concentrations inside the crater in a layer above an outcrop of bedrock and on the slope just under the outcrop. Hematite usually forms in association with liquid water, so it holds special interest for the scientists trying to determine whether the rover landing sites ever had watery environments possibly suitable for sustaining life. The map uses data from Opportunity's miniature thermal emission spectrometer, which identifies rock types from a distance. "We're seeing little bits and pieces of this mystery, but we haven't pieced all the clues together yet," Squyres said. Opportunity's Mössbauer spectrometer, an instrument on the rover's robotic arm designed to identify the types of iron-bearing minerals in a target, found a strong signal in the soil patch for olivine. Olivine is a common ingredient in volcanic rocks. A few days of analysis may be needed to discern whether any fainter signals are from hematite, said Dr. Franz Renz, science team member from the University of Mainz, Germany. To get a better look at the hematite closer to the outcrop, Opportunity will go there. It will begin by driving about 3 meters (10 feet) tomorrow, taking it about halfway to the outcrop. On Friday it will dig a trench with one of its front wheels, said JPL's Dr. Mark Adler, mission manager. Opportunity's twin, Spirit, today is reformatting its flash memory, a preventive measure that had been planned for earlier in the week. "We spent the last four days in the testbed testing this," Adler said. "It's not an operation we do lightly. We've got to be sure it works right." Tomorrow, Spirit will resume examining a rock called Adirondack after a two-week interruption by computer memory problems. Controllers plan to tell Spirit to brush dust off of a rock and examine the cleaned surface tomorrow. Each martian day, or "sol," lasts about 40 minutes longer than an Earth day. Spirit begins its 33rd sol on Mars at 2:43 a.m. Thursday, Pacific Standard Time. Opportunity begins its 13th sol on Mars at 3:04 p.m. Thursday, PST. posted by Gary Williams at 12:31 AM | link | Wednesday, February 04, 2004 via memepool via The power of Google

February 2, 2004 So now it really begins in earnest. Opportunity has been cranking away for several sols now, and as of yesterday Spirit is back up and running too. So now, for the first time, we have two rovers with twelve wheels in the dirt, both doing science. It's not easy to deal with. The two landing sites are on totally opposite sides of the planet, which means that when it's the middle of the night for one rover, it's noon for the other. The bottom line is that there's something going on pretty much all the time. But as tempting as it is to try to work on both rovers at once, you just can't do it. Unfortunately, you just have to sleep sometime! Personally, I've been working on Opportunity, where the big story is that fantastic rock outcrop less than ten meters away from us. We're going to spend some sols working on the soil before we head over to it, but it shouldn't be long. And on Spirit (from what I hear... I've been sleeping, really) the news is that they're back to work on the rock we've named Adirondack. Now that we know what the outside of Adirondack looks like, the next step is going to be to take the RAT to it and see what it's like on the inside.
The color image on the lower left shows a rock outcrop at Meridiani Planum, Mars. This image was taken by the panoramic camera on the Mars Exploration Rover Opportunity, looking north, and was acquired on the 4th sol, or martian day, of the rover's mission (Jan. 27, 2004). The yellow box outlines an area detailed in the top left image, which is a monochrome (single filter) image from the rover's panoramic camera. The top image uses solid colors to show several regions on or near the rock outcrop from which spectra were extracted: the dark soil above the outcrop (yellow), the distant horizon surface (aqua), a bright rock in the outcrop (green), a darker rock in the outcrop (red), and a small dark cobblestone (blue). Spectra from these regions are shown in the plot to the right.

Airlines always demand photo IDs, and hotels increasingly do so. They're often required for admittance into government buildings, and sometimes even hospitals. Everywhere, it seems, someone is checking IDs. The ostensible reason is that ID checks make us all safer, but that's just not so. In most cases, identification has very little to do with security. Let's debunk the myths: First, verifying that someone has a photo ID is a completely useless security measure. All the Sept. 11 terrorists had photo IDs. Some of the IDs were real. Some were fake. Some were real IDs in fake names, bought from a crooked DMV employee in Virginia for $1,000 each. Fake driver's licenses for all 50 states, good enough to fool anyone who isn't paying close attention, are available on the Internet. Or if you don't want to buy IDs online, just ask any teenager where to get a fake ID. Harder-to-forge IDs only help marginally, because the problem is not making sure the ID is valid. This is the second myth of ID checks: that identification combined with profiling can be an indicator of intention. Our goal is to somehow identify the few bad guys scattered in the sea of good guys. In an ideal world, what we would want is some kind of ID that denotes intention. We'd want all terrorists to carry a card that says "evildoer" and everyone else to carry a card that said "honest person who won't try to hijack or blow up anything." Then, security would be easy. We would just look at people's IDs and, if they were evildoers, we wouldn't let them on the airplane or into the building. This is, of course, ridiculous, so we rely on identity as a substitute. In theory, if we know who you are, and if we have enough information about you, we can somehow predict whether you're likely to be an evildoer. This is the basis behind CAPPS-2, the government's new airline passenger profiling system. People are divided into two categories based on various criteria: the traveler's address, credit history and police and tax records; flight origin and destination; whether the ticket was purchased by cash, check or credit card; whether the ticket is one way or round trip; whether the traveler is alone or with a larger party; how frequently the traveler flies; and how long before departure the ticket was purchased. Profiling has two very dangerous failure modes. The first one is obvious. Profiling's intent is to divide people into two categories: people who may be evildoers and need to be screened more carefully, and people who are less likely to be evildoers and can be screened less carefully. But any such system will create a third, and very dangerous, category: evildoers who don't fit the profile. Oklahoma City bomber Timothy McVeigh, Washington-area sniper John Allen Muhammed and many of the Sept. 11 terrorists had no previous links to terrorism. The Unabomber taught mathematics at UC Berkeley. The Palestinians have demonstrated that they can recruit suicide bombers with no previous record of anti-Israeli activities. Even the Sept. 11 hijackers went out of their way to establish a normal-looking profile; frequent-flier numbers, a history of first-class travel and so on. Evildoers can also engage in identity theft, and steal the identity -- and profile -- of an honest person. Profiling can result in less security by giving certain people an easy way to skirt security. There's another, even more dangerous, failure mode for these systems: honest people who fit the evildoer profile. Because evildoers are so rare, almost everyone who fits the profile will turn out to be a false alarm. This not only wastes investigative resources that might be better spent elsewhere, but it causes grave harm to those innocents who fit the profile. Whether it's something as simple as "driving while black" or "flying while Arab," or something more complicated such as taking scuba lessons or protesting the Bush administration, profiling harms society because it causes us all to live in fear...not from the evildoers, but from the police. Security is a trade-off; we have to weigh the security we get against the price we pay for it. Better trade-offs are to spend money on intelligence and analysis, investigation and making ourselves less of a pariah on the world stage. And to spend money on the other, nonterrorist security issues that affect far more Americans every year. Identification and profiling don't provide very good security, and they do so at an enormous cost. Dropping ID checks completely, and engaging in random screening where appropriate, is a far better security trade-off. People who know they're being watched, and that their innocent actions can result in police scrutiny, are people who become scared to step out of line. They know that they can be put on a "bad list" at any time. People living in this kind of society are not free, despite any illusionary security they receive. It's contrary to all the ideals that went into founding the United States. Bruce Schneier, CTO of Counterpane Internet Security in Cupertino, is the author of "Beyond Fear: Thinking Sensibly About Security in an Uncertain World" (Copernicus Books, 2003). _______________________________________________ Politech mailing list Archived at http://www.politechbot.com/ Moderated by Declan McCullagh (http://www.mccullagh.org/) posted by Gary Williams at 2:49 PM | link | via Marsrovers.JPL.NASA.gov Lame NASA Press Release That Seems To Be Running Out Of Things To SayOpportunity extended its arm early today for the first time since pre-launch testing. "This was a great confirmation for the team," said Joe Melko of NASA's Jet Propulsion Laboratory, Pasadena, Calif. Melko is mechanical systems engineer for the arm, which is also called the instrument deployment device.Mission controllers at JPL are telling Opportunity to use two of the instruments on the arm overnight tonight to examine a patch of soil in front of the rover. A microscope on the arm will reveal structures as thin as a human hair and a Mössbauer Spectrometer will collect information to identify minerals in the soil, according to plans. Tomorrow, the rover will be told to turn the turret at the end of the arm in order to examine the same patch of soil with another instrument, the alpha particle X-ray spectrometer, which reveals the chemical elements in a target.

January 31, 2004 What a wonderful day. We now have twelve wheels safely on martian soil. I've said since the very beginning of this thing that there were six terrifying events over the course of this mission... two launches, two landings, and two egresses. All six of those are behind us now. We have two healthy rovers, each with completely healthy payloads, on the surface of Mars and ready to explore.
We also have a whole bunch of hematite at Meridiani! The first Mini-TES results are in, and we've got a slam-dunk identification of hematite in the gray soil granules around the lander. This spectrum shows a laboratory spectrum of hematite (the red curve) and a Mini-TES spectrum of the dark soil near the lander (the yellow curve). The close match of the up-and-down lines at the right end of the plot is what tells us we've definitely found the hematite. There's lots more news to tell, but a bunch of people are about to head out to celebrate (at 7:00 AM Pacific time!)and I'm going to join them... via CNET News.com posted by Gary Williams at 2:37 PM | link | via Scotsman News ![]()
