Mars Rovers Get Extra 18 Months

iamlucky13 writes "NASA has stated in the latest mission press release that funding for an additional 18 months of exploration has been approved. The rovers have breezed through 14 months of operation so far, and the money will cover expenses through September of 2006. The rovers are still operating well, and recently both experienced dramatic power boosts from their solar cells. They are no longer like new, however. Opportunity has recently experienced data loss from one of its spectrometers, while Spirit has a smudged camera lens, a heavily used rock abrasion tool, and has previously struggled with intermittent steering issues."

      Incorrect. It's not an arbitrary distinction whatsoever. The region where the solar wind drops below the speed of sound is called the "termination shock". Just like how on an aircraft, differences between supersonic and subsonic regions of flow create strong turbulent artifacts, so will happen with the solar wind (which is charged, meaning that it produces electromagnetic radiation when its path is changed). More significantly, at the heliopause, another issue arises: charge. The heliopause is where the solar wind balances out the pressure of the interstellar medium. Do the charged particles collect there, and if so, how densely? This could have profound effects for any kupier belt (or beyond) missions, as well as our models of solar system formation. Heck, we don't even know how far out the termination shock and heliopause are (and they're not in constant locations, as the sun is moving with respect to the local interstellar medium; the shape is something like a comet). Despite what we don't know about it, we do know this: the heliosphere is the source of the most powerful radio waves in our solar system - more than 10 trillion watts. By the way - it was Voyager who first detected these emissions.

      After the heliopause comes the heliosheath, which has its own set of properties which are largely unknown. It's the area where the solar-influenced material blends into the interstellar medium (and getting any data on the interstellar medium would be a great boon for astronomy)

      If a wheel develops a problem during the life of the rover it may be necessesary to drive it backwards.

      Also, these robots, like many others, spent a lot of their time getting too close to hazards and having to reverse away, so being able to see behind you is pretty important.

      And another thing ... a good way to measure how far you have gone is to take a picture of your tracks. This makes it easy to integrate your movements and calculate your new position

    I like both rovers. :) But I think they get more funding because of "to moon, _mars_ and beyond" thing. If NASA want to fulfill this goal, then must gather as much information as possible about Mars.

      I don't like the idea of scraping Voyager too, but if we really get to the Mars the amount of technology developed and overall advancement of space exploration would make another long distance probes more likely than not.

      In other words, if we go to the Mars we may some day go beyond our system but if we don't then surely not.

    To improve lubrication the rovers have been driving backwards a lot of times lately. I remember they started doing this when one of the front wheels of the Spirit rover started to show more friction. After driving in reverse the friction became less.

    Perhaps we are getting back to the good old days of NASA. You just cannot go cheap on space/planet exploration. Look at the original Pioneer probes, these things might just run forever, they were overengineered for the task from the get go. After all of the recent shuttle and probe failures, I'm glad NASA is getting more than they paid for on this one. Space exploration shoud ensure the future of the human race.........

    Frankly, Voyager is useless now, and money used to fund that project could be going to more worthwhile projects like the JPL rovers. The Voyager project was never meant to measure data outside of the solar system, but rather to gather data on the gas giants and outer planets. They accomplished that a long time ago.

    Yes, but tell me, when is the next time we'll have a probe that far out in say, oh, the next 20-30 years?? While we're out there and it's sending data we might as well gather it. All data is new data that can be used. And as for "the original mission", don't forget the rovers were only supposed to be for about 90 days and look how much they've done.

    "For the past two years or so, Voyager 1 has detected phenomena unlike any encountered before in all its years of exploration. These observations and what they may infer about the approach to the termination shock have been the subject of on-going scientific debates. While some of the scientist believed that the passage past the termination shock had already begun, some of the phenomena observed were not what would have been expected. So the debate continues while even more data are being returned and analyzed."
