Mars Rover Sees Mystery Rock Suddenly Appear

One fine day on Mars, Opportunity, a robotic mobile space probe from Planet Earth--from a nation called America--was taking images of the surrounding rocks, controlled as it was by geologists. So far, nothing seems unusual, since geologists like rocks and want to take pictures of them. However, it appears one of the rocks previously omitted seems to have wanted to get in on the photo. Hold on. This is going to shock you.

The geologists at JPL have called the rock Pinnacle Island, but it looks like a jelly donut and is about the same size. Opportunity, which has some analysis capability, determined it is a very unusual rock indeed; the center "jelly" is made of sulfur, magnesium, and manganese and a whole bunch of other things of that sort, reminding me of the manganese nodules at the bottom of the oceans of Planet Earth. Yet it is different from them also.

But what really got everyone going is how it got there, being that it clearly was NOT there 12 Martian days before. Geologists are used to rocks not moving around, and it surprises them when one does.

"It's about the size of a jelly doughnut," Exploration Team leader Steven Squyres said in a talk reported by Ian O'Neill of Discovery News. "It was a total surprise, we were like 'wait a second, that wasn't there before, it can't be right. Oh my God! It wasn't there before!' We were absolutely startled." He continued, "I don't know what any of this means. We're completely confused, everybody on the team is arguing and fighting. We're having a wonderful time!"

  1. How's the wind out there on Mars, I wonder?

  2. Yes, apparantly wind does exist on Mars. Of the 6 possible explanations on's site, wind is never mentioned, except once, which I found amusing:

    "Theories, theories, myriads upon myriads of them, streamed over me like wind-borne
    leaves, like the contents of some titanic paper-factory flung aloft by the storm, like
    dust-clouds in the hurricane advance of the mind."

    Yeah: "wind -borne" is a major clue, right there, I'd wager.

  3. Here's a link to a NASA report discussing wind on Mars

      I think you have another theory, Thorns. Ordinarily, the winds on Mars cannot move centimeter sized rocks around, because the density of the atmosphere of Mars is very low, so even with the famed Martian windstorms this does not happen. But if the rock was loaded with vessicles, like pumice, at some point the wind could move it. The question is can enough voids be in a realistic rock to enable this. Something to consider!! Thorns you have thought of a possibility that the Squyres scientific team did not consider, or if they did, they did not list it. Good job.

    Work from home theory is fast gaining popularity because of the freedom and flexibility that comes with it. Since one is not bound by fixed working hours, they can schedule their work at the time when they feel most productive and convenient to them. Women & Men benefit a lot from this concept of work since they can balance their home and work perfectly. People mostly find that in this situation, their productivity is higher and stress levels lower. Those who like isolation and a tranquil work environment also tend to prefer this way of working. Today, with the kind of communication networks available, millions of people worldwide are considering this option.

    Women & Men who want to be independent but cannot afford to leave their responsibilities at home aside will benefit a lot from this concept of work. It makes it easier to maintain a healthy balance between home and work. The family doesn't get neglected and you can get your work done too. You can thus effectively juggle home responsibilities with your career. Working from home is definitely a viable option but it also needs a lot of hard work and discipline. You have to make a time schedule for yourself and stick to it. There will be a time frame of course for any job you take up and you have to fulfill that project within that time frame.

    There are many things that can be done working from home. A few of them is listed below that will give you a general idea about the benefits of this concept.

    This is the most common and highly preferred job that Women & Men like doing. Since in today's competitive world both the parents have to work they need a secure place to leave behind their children who will take care of them and parents can also relax without being worried all the time. In this job you don't require any degree or qualifications. You only have to know how to take care of children. Parents are happy to pay handsome salary and you can also earn a lot without putting too much of an effort.

    For those who have a garden or an open space at your disposal and are also interested in gardening can go for this method of earning money. If given proper time and efforts nursery business can flourish very well and you will earn handsomely. But just as all jobs establishing it will be a bit difficult but the end results are outstanding.

    Freelance can be in different wings. Either you can be a freelance reporter or a freelance photographer. You can also do designing or be in the advertising field doing project on your own. Being independent and working independently will depend on your field of work and the availability of its worth in the market. If you like doing jewellery designing you can do that at home totally independently. You can also work on freelancing as a marketing executive working from home.

    Diet food
    Since now a days Women & Men are more conscious of the food that they eat hence they prefer to have homemade low cal food and if you can start supplying low cal food to various offices then it will be a very good source of income and not too much of efforts. You can hire a few ladies who will help you out and this can be a good business.

    Thus think over this concept and go ahead.
