Mars Curiosity Rover's First Road Trip Planned

Posted by Soulskill on from the off-to-kill-cats dept.

littlesparkvt writes "NASA has announced the first destination for the Curiosity Rover. They're sending it to 'Glenelg,' a natural intersection of three kinds of terrain. 'The trek to Glenelg will send the rover 1,300 feet (400 meters) east-southeast of its landing site. One of the three types of terrain intersecting at Glenelg is layered bedrock, which is attractive as the first drilling target. "We're about ready to load our new destination into our GPS and head out onto the open road," Grotzinger said. "Our challenge is there is no GPS on Mars, so we have a roomful of rover-driver engineers providing our turn-by-turn navigation for us." Prior to the rover's trip to Glenelg, the team in charge of Curiosity's Chemistry and Camera instrument, or ChemCam, is planning to give their mast-mounted, rock-zapping laser and telescope combination a thorough checkout. On Saturday night, Aug. 18, ChemCam is expected to "zap" its first rock in the name of planetary science. It will be the first time such a powerful laser has been used on the surface of another world.'"

    Nobody Seems To Notice and Nobody Seems To Care - Government & Stealth Malware

    In Response To Slashdot Article: Former Pentagon Analyst: China Has Backdoors To 80% of Telecoms 87

    How many rootkits does the US[2] use officially or unofficially?

    How much of the free but proprietary software in the US spies on you?

    Which software would that be?

    Visit any of the top freeware sites in the US, count the number of thousands or millions of downloads of free but proprietary software, much of it works, again on a proprietary Operating System, with files stored or in transit.

    How many free but proprietary programs have you downloaded and scanned entire hard drives, flash drives, and other media? Do you realize you are giving these types of proprietary programs complete access to all of your computer's files on the basis of faith alone?

    If you are an atheist, the comparison is that you believe in code you cannot see to detect and contain malware on the basis of faith! So you do believe in something invisible to you, don't you?

    I'm now going to touch on a subject most anti-malware, commercial or free, developers will DELETE on most of their forums or mailing lists:

    APT malware infecting and remaining in BIOS, on PCI and AGP devices, in firmware, your router (many routers are forced to place backdoors in their firmware for their government) your NIC, and many other devices.

    Where are the commercial or free anti-malware organizations and individual's products which hash and compare in the cloud and scan for malware for these vectors? If you post on mailing lists or forums of most anti-malware organizations about this threat, one of the following actions will apply: your post will be deleted and/or moved to a hard to find or 'deleted/junk posts' forum section, someone or a team of individuals will mock you in various forms 'tin foil hat', 'conspiracy nut', and my favorite, 'where is the proof of these infections?' One only needs to search Google for these threats and they will open your malware world view to a much larger arena of malware on devices not scanned/supported by the scanners from these freeware sites. This point assumed you're using the proprietary Microsoft Windows OS. Now, let's move on to Linux.

    The rootkit scanners for Linux are few and poor. If you're lucky, you'll know how to use chkrootkit (but you can use strings and other tools for analysis) and show the strings of binaries on your installation, but the results are dependent on your capability of deciphering the output and performing further analysis with various tools or in an environment such as Remnux Linux. None of these free scanners scan the earlier mentioned areas of your PC, either! Nor do they detect many of the hundreds of trojans and rootkits easily available on popular websites and the dark/deep web.

    Compromised defenders of Linux will look down their nose at you (unless they are into reverse engineering malware/bad binaries, Google for this and Linux and begin a valuable education!) and respond with a similar tone, if they don't call you a noob or point to verifying/downloading packages in a signed repo/original/secure source or checking hashes, they will jump to conspiracy type labels, ignore you, lock and/or shuffle the thread, or otherwise lead you astray from learning how to examine bad binaries. The world of Linux is funny in this way, and I've been a part of it for many years. The majority of Linux users, like the Windows users, will go out of their way to lead you and say anything other than pointing you to information readily available on detailed binary file analysis.

    Don't let them get you down, the information is plenty and out there, some from some well known publishers of Linux/Unix books. Search, learn, and share the information on detecting and picking through bad binaries. But this still will not touch the void of the APT malware described above which will survive any wipe of r/w media. I'm convinced, on both *nix and Windows, these pieces of APT malware

      If something is living there, then by definition there's an ecosystem - it may not be a diverse one, but it would be there.

      There is a pretty good reason to think that geological material (potentially harboring microbes) has been exchanged several times over the past few billion years, with the K-T event (that killed off the dinosaurs) being one of those events that sent material back to Mars again and likely seeded at least some sort of life almost everywhere in the Solar System where liquid water can be found.

      If fact, a strong hypothesis suggests that life as we know it may have even originated on Mars and then came to the Earth many millions of years ago to see the Earth.

      This isn't galactic scale panspermia but rather just something happening on a stellar system scale and certainly sounds reasonable with current scientific thought on the subject. When Apollo 12 landed next to the Surveyor lander and then found microbes which lived on the surface of the Moon for several years (from the Surveyor spacecraft), it seems reasonable that at least some microbes could cope with a multi-year journey through the solar system.

      In other words, the Drake equation would not be altered here as it still is just a sample size of one, just on a larger scale.

      On the other hand, if you could find some type of life on Mars that uses something other than DNA to pass genetic information, that would be incredible in so many ways. I would expect that any sort of life on Mars must have found ways to cope with the environment there that would make it quite different from life on the Earth, even different from the extremophiles that are often used by comparison, but there may still be common genes that indicate a shared ancestor. Curiosity is not going to be examining potential life forms to that level of detail, so that would need to be a follow-up experiment if anything resembling a life form is even found at all.

      Interplanetary panspermia might give hints to interstellar panspermia though, or at least not rule it out as a mechanism for spreading life throughout the universe. It may even be hypothesized that after a planet, any planet at all in a galaxy, has been able to develop life forms that over a comparatively short period of time (when measured in billions of years) the entire galaxy is eventually "infected" with life to some degree at least where it might be remotely possible. Even though it is still just a sample size of one in terms of having life self-generate, in terms of calculating the number of planets in the Milky Way that could have life it might make that part of the Drake equation much closer to one than zero.
