Second Opportunity For Mars Rover

An anonymous reader writes "The Mars Opportunity rover faces a challenging survey around the rim of the stadium-sized Endurance Crater. In addition to what was previously described as the critical choice to go into the steep crater at the risk of not being able to get back out, this "most spectacular view we've seen of the Martian surface" may aid in answering how deep an ancient sea or lake might have been and how long it lasted. Endurance Crater appears much older and thus may pre-date arrival of significant standing water."

  4. Hmm by RabidChicken · · Score: 4, Interesting

    This makes me wonder just how long exactly the rover will last. Another month? Year? Just how much battery power is there to last it? Will it last simply until a martian storm hits it? I personally think this is a great mission and every nugget of data is opening new doors. I would like to see it last for quite a while, even if there is no press coverage. P.S. The earlier comment about adding a mic to record the sounds on mars may seem trivial, but I say it'd be a great idea and inspire wonder (and a neato MP3 ;)

      NASA really has everyone believing the "dust on the panels" routine. I'm sure it could be a problem under certain circumstances, but if you ask me, they are hyping this problem so that they can set expectations artificially low.

      By setting low expecations, they make themselves look like heroes if they are able to exceed their original mission parameters, and they cover their butts if things turn sour.

      I think this is pretty common among technical types, since technology (especially cutting edge tech 100 million miles away on an unexplored world) is so unpredictable.

    Life as we know it requires water to develop. Finding history of water on Mars is the first step in the seach for life. Hopefully this mission can influence our leaders to spend money on a project to search for life, which would be beneath the surface, which would be much more expensive. I think the missions were a great success as they found evidence of water and rallied the interest of the general population to push for more funding.

    There was more than one goal. It would have been nice to find existance of life, but this is a stepping stone for bigger things. Sending robots to mars and successfully landing them gets you good information for future missions. Especially if you want humans to get there. I would rather have some robots be the first to try landings on a different planet.

    According to the article, the following plan will opportunity follow:
    1. Make a round on the edge of the Endurance Crater to make measurements and see how steep the crater is.
    2. If (with little risk) opportunity can drive in it and back out, it will do so before doing the following points, otherwise, do the following points first before moving into Endurance.
    3. Examine the area around the heatshield, to check both the heatshield useful for future missions and to look in the deep hole the heatshield made into mars.
    4. Examine some other place it passed before (but then did not have enough time) to check the composition of a rock that is different than others.

    Well we didn't have conclusive evidence that formations on Mars were sculpted by H20. In fact, a competing theory is that many geologic features you see (including seasonal channels on crater walls) could have been carved by CO2 flows.

    I'm about to go to work, but you can definitely dig around google for evidence, I found a few sites by just typing in CO2 flows.

    The overarching goal of the Mars Exploration Rovers was not to determine if there was life on Mars. The goal was to determine if water existed in liquid form in the past. Hematite and cross bedding visible at the Opportunity landing site finally gave us the conclusive answer we needed.

    Now that we know water did exist on the surface of the Red Planet, we can try to tackle new questions such as; Did life ever exist? What happened to the water?

    Yeah... too bad Batman had to use his belt the day they were launching the rover. His bathook would have been really useful.

    On a more serious note, the logistics of firing and using a grappling hook are far outside the realm of 'faster, better, cheaper' methods. Simple is where it's at, and Rube Goldberg devices to pull the rover out of pits are not on the menu.

    I do hope they choose to go down... I wanna see what that ripply stuff at the bottom of the crater is made out of.

    then wouldn't there be enough science there to study until the end of the rover's life? They spent what seemed like a very long time just on that one small crater where the rover landed in. Granted, a lot of the initial time was used for calibration, systems tests, etc, but they spent a lot of time there. If this crater is the size of a stadium, I think it is safe to say that it will last them until the end of the rovers lifespan.

      You may be right but there are a lot of things that the rover wants to inspect beforehand, the heatshield for example that touched down just a few hundred meters away. They will go down eventually even if the rover might get stuck but not before they visited some targets ontop of the crater.

    I am going out on a limb here and say that this entire mission has really been a big disappointment to me. Although it did enhance our knowledge of the planet considerably, it did not even attempt to verify if there was/is life on the planet, which is the end goal.
    The mission exceeded all it's objectives. I don't understand how that can be considered a disappointment. Detecting life, as discovered by the Viking missions, is not always an easy task. Instead, these two rovers have transformed our understanding of Martian geology, for the first time given unrefutable evidence of water's presence, traversed the greatest distance on any body's surface by an unmanned vehicle, and sent back some damn cool pictures. All for a fraction of what the war in Iraq is costing us as taxpayers.
    Finding life may be the "end goal" for public relations, etc., but I'm sure there are plenty of planetary geologists that have found these missions to be among the most important endeavours in the history of unmanned missions.
