Curiosity Starts Driving 35

littlesparkvt tips news that the Curiosity Mars rover began driving today at Bradbury Landing in Gale Crater. The rover rolled forward about 4.5 meters, then stopped, rotated 120 degrees, and rolled another 2.5 meters. The article has a picture of the rover's tracks in the Martian dust, and you can browse the image gallery or raw image feed for more. Matt Heverly, the rover's lead driver, confirmed that the mobility system is functioning perfectly in the lead-up to its first major land trek. "Curiosity will spend several more days of working beside Bradbury Landing, performing instrument checks and studying the surroundings, before embarking toward its first driving destination approximately 1,300 feet (400 meters) to the east-southeast." Reader redletterdave adds news that NASA has released an enhanced video of Curiosity's descent from space, which is pretty cool to watch. There was also some minor bad news yesterday; one of the wind speed sensors on the REMS weather instruments was permanently damaged during landing. Emily Lakdawalla explains,"The reason there were two is that it helped triangulate wind speed and also improve accuracy of wind speed measurements when one of the booms is aimed windward or leeward. So the quality of the wind speed data will be harmed, but there will still be wind speed data."

    Will it turn off its turn signal?
    • I'm more concerned about whether it will be talking on its cell phone (ok, X band radio) while driving. I'd hate to see it crash because of distracted driving.

    Tragically, it ran over a cat, who perished.

      The Pu power source makes about 100W of electricity and keep the rover warm. The purpose of slow speed is not to hit things, not to use lot of power, AND because that is completely unnecessary.

      And your reference to "Back to the Future" is getting old.

      • It just needs to get back to 1985, where it will be hip and edgy again!

        Just because you kids dont appreciate classic movies, we're supposed to stop? Stuff that.

        And who modded Buzz "AC" Killington here as insightful? Holy crap. Someone is just slapping that tag on everything, the way gammy does Frank's Red Hot Sauce.

    Minor indeed; that any part of that rover is still functional after that landing (and the US's perverse budget) is a testament to the general badassery of the engineers, programmers, and builders behind that thing.

      Most of the rover was built during the minor boom years* of the mid 2000's. Thus, budget was not really the same issue as it is today. But I agree it's amazing that more hasn't gone wrong with the complexity of both the rover and the landing involved.

      A sky-crane was used instead of a Viking-style landing to avoid kicking up too much debris near the vehicle.

      However, most of the thrust would then be underneath, not to the side like the sky-crane gave. Thus, less vehicle-deck-directed pebbles would be kicked up it seems if they did a Viking-style landing, but more (local) dust.

      Being they speculate flying pebbles caused the wind-sensor damage based on pebbles found on deck, perhaps the Viking approach is not so bad after all, relatively speaking. A dust bath may be better than a pebble bath.

      * "Bubble years" may be a better description.
         

      • In the various videos etc it looked like the thrusters on the crane were angled outward, if so I imagine it would kick up less stuff in the landing zone itself than landing on top of a torch... Either way you're getting pebbles. Irregularly-shaped rocks bouncing off irregularly-shaped surfaces can exhibit all kinds of crazy behavior. The fuel filter in my 300SD developed a dent with accompanying pinhole which from what I can tell is due to rock damage, and it's not mounted particularly low, but my county sh

          The landing area there appears relatively smooth such that there's little for debris to bounce off, at least until the thrusters blow away the top soil, but then you have problems either way. Then again, it's hard to know what's at a landing spot until you get there.

          I just wonder if the complexity of a crane couldn't be put into protective covers instead.

  • My /. prophecy came true:

    The rover is doing donuts:

    For my next prediction, the rover will find another Mitt Romney tax haven, on Mars.

  • I hope it's not calling home and driving at the same time, it can get a ticket.

  • Good. Now send it to "unstick" the other rover...
  • Watch out for that stop sign!!!!!

    DAAAAAAAaaadD! It's fine!

    OH, you mean the Mars probe.

  • I thought curiosity killed the cat...
  • When are we sending a tow truck to unstick that other rover, maybe refill the tires... Wash the windows^Wsolar panels...

  • Roll out!
