Rover Accidentally Uncovers Mars Hydrothermal Vent

The rover Spirit has been dragging one wheel around the surface of Mars for some time. One of the resulting gouges revealed a mineral deposit which was probably caused by a hydrothermal vent. This implies a large amount of water was present when the vent was active.

    Even it's broken dragging wheel makes informative discoveries on the Martian surface. The Mars rovers are surely one of our most successful robotic missions ever. Kudos to JPL and NASA and the American Congress for keeping to fund these missions. Let's all keep our fingers crossed for the Phoenix lander this Sunday - landing is at approximately 5PM EST this Sunday on NASA TV.

      I'm positive I remember reading something about that too...

      Personally, I think they should mass produce more of those rovers and blast them off to mars.... spirit and opportunity were sent to two very boring places on mars that were deemed as safe as possible to land after so many previous failures.

      We should be sending rovers nearer to the poles, to olympus mobs, to valles marineris... etc. Think of the fascinating stuff we'd find if we actually sent rovers somewhere INTERESTING.

      That's good to know (I hadn't heard that anywhere), though Spirit is essentially out of commission for a few more months due to winter weather, unless it gets its solar panels cleaned off by wind. Right now it's having a hard enough time just keeping warm.

  4. Oops by Magdalene · · Score: 5, Funny

    It is certainly amazing that the rover is still running well after original mission end date and altogether amusing that, much like most other brilliant advances in science, the hydrothermal vent evidence was discovered completely by accident.

    Chance; 'the powers that be'; chaos; coincidence; divine intervention; flying spaghetti monster or just the universes' subversive perverse version of humour; you get the feeling that if it weren't for an infinite amount of insanely improbable accidents, not only science but life as we know it just wouldn't have happened.

    Come to think of it, The *Big Bang* probably happened because Chaos and God were up in God's room with Chaos' new chemistry set and they were arguing over who got to light the Bunsen burner when they accidentally knocked the "NEW INSTANT UNIVERSE!" out of the box and onto the floor.

    (read instructions carefully. some assembly required. very fragile. may explode if dropped. do not unpack near open flame, spark or antimatter. Batteries not included. your results may vary. not responsible for damages incurred by improper implementation of instructions. universe may be damaged by improper handling. )

    They were probably grounded for 240,000 years.

  6. That would be a mistake by WindBourne · · Score: 4, Interesting

    While these rovers are pretty cool, they really do not contain that much equipment. In addition, once landed, they really do not travel that far. Instead, we would be better served with either a unique airplane or a balloon model. While they are testing the airplane idea, I would think that unless the wings can fold up, that when the infamous mars storms hit, that it will be all over. The balloon idea has the advantage of being able to fold up tight, but it can not be as easily controlled. One idea that I saw out there was to release 5-10 balloons with cameras and no ability to land. Right now, MRO has a camera that sees .3M, but an inexpensive camera on the balloon, should be able to take that much smaller due to height and far less atmosphere.

    Quite honestly, the rovers are simple extensions of pathfinder, but we now need a combination of large jumps for spot checks and the ability to do a lot more science. The balloon approach would give us the ability to jump with small tests, while the MSL will be the logical outcome of the rovers combined with polar express. The biggest item that will come from the polar express will simply be the landing under power.

  7. Difficult? by jgoemat · · Score: 3, Interesting

    Would they even work on Mars? The pressure is less than 1/1000th that of the Earth, or the same pressure as over 30 miles up on Earth. The U-2 spy plane only flew about 13 miles high and the SR-71 only reaches 15 miles. High-altitude weather balloons don't get much over 20 miles up I don't think. While the decreased gravity on Mars might help with the plane idea, would it help with the balloon? Just curious, but wouldn't the decreased gravity adversely affect the buoyancy as much as it would help by making the payload lighter?

    1. Re:Difficult? by WindBourne · · Score: 2, Informative

      There are a number of models that are being experimented with that should work. Obviously helium AND will have a much small payload than here due to decreased density. The problem will be that the balloons will NOT go high up. That means if they hit Olympus Mons, well, it is stuck. They have also tested several wings that they are looking at for preditor type aircrafts. They are doing that work over here in Colorado.

      Minor correction, but the atmospheric pressure on Mars is generally said to be 1/150th of that of earth, or between 6 to 10 millibars.

      In the Martian atmosphere, Hydrogen works better as a lifting gas. It'll give more lift per cubic meter than helium, lighter for launching into space and can compress into smaller canisters for in flight transportation. All this without the corresponding dangers and safety concerns since there is no oxygen in the Martian atmosphere to mix with it and make it explosive.

    Right now, they wouldn't learn anything, because they would be dead. If NASA is dicking around with anything, it would be the ISS. Haul that low orbit pile of resources into a much more stable orbit, and then use it for parts/construction platform for a station with centrifugal gravity and as close to a closed ecosystem as we can manage. Until we improve those technologies, to the level of near permanent space habitats, then multi-year space exploration will be the sole domain of robots.
