Mars Rovers On Final Approach

leapis writes "In the wake of the possible loss of the Beagle 2 Mars probe, let us not forget that the Mars Rovers are scheduled for arrival in orbit this weekend. As noted in this article at Space.com, the fourth and final course correction has been made, and Spirit, the first of two spacecraft, will touch down around 22:34 on 3 Jan 2004. More information and a countdown to the landing can be found here."

    Does anyone know if it's possible to get accurate data from these recent Mars Probes into the Celestia 3d space simulator?

    I would love to watch with my son as these craft approach and land on Mars in real time! Currently, we enjoy doing fly-bys between Mars' and moons, the ISS and Hubble, and the stars, but this would be more memorable than watching videobites after the fact on CNN. TIA.

      Normal folks can't get their hands on the detailed data. Only NASA has access to that.... for national security reasons, yeah, that's the ticket. Actually, I can't think of a good reason why they wouldn't release the data so it has to be available if you know who to ask.

    Truth is, our need to expand will trump any chance of primitive life on mars developing.

    Do we have the right? I suppose if you take the really long view, then no; otherwise its survival of the fittest!

      Do we have the right? I suppose if you take the really long view, then no

      How does taking a really long view at things take away our right to expand? Although I can't state this as fact I would assume that life have been around, birthed, destroyed, expanding, collapsed, exploded, imploded, and frozen/burnt eons before humans ever thought to themselves, "Hey, living in the dirt sucks. Let's make air conditioning and gameboys while flinging voyeuristic webcams into Martian's showers."

      I guess it all comes down to what you believe. If you believe in some God/Gods/Omnipotent Force then you just have to ask yourself what was his/her/it's point for us during creation? I would say it was for us to learn. Then what was the point of other life? Well, maybe it was just other tries that didn't work out, or it could be meant for fuel. God did make us so we had to eat something and other life seems to be it.

      If you believe that life is just a fluke in an infinite universe then there is no set point and thus no restriction of right, unless you count your moral values as universal law. In which case you would be imposing your morals on others just like they where doing to the non-human life form.

      Maybe you where just trolling? I never can tell for sure.

    And let's not forget that the Beagle 2 was really a last minute 'add on' to the main mission - the orbiter. Poor Mars Express seems to be lost in the media coverage of the of the Beagle. Done on the cheap and quickly, the real surprise would have been if it landed successfully. Kudos to the ESA for trying something as ambitious as this in their relatively early days of solar system exploration and lets hope we get great science from Express and the US landers.

    ...let us not forget that the Mars Rovers are scheduled for arrival in orbit this weekend.
    Erm, they aren't going to arrive in ORBIT at all. They're simply going to smash straight into Mars's atmosphere without trying to orbit first. Why spend the energy (and thus propellant mass) firing engines to orbit the planet when you actually just want to GET ON THE PLANET? Mars has a thin-but-functional atmosphere that you can use to slow yourself down so you drop for a nice landing. ^_^

      well, it had a CHANCE. Don't be so impatient. whether it's next week or in 3 years or in 20 years, we'll probably know n our lifetimes. You know, once we know there's life, we can't imagine so much anymore. I'd love to know, but I'm not in a hige hurry to lose that.

  9. Re:Better chances by Lispy · · Score: 2, Insightful

    I was always wondering why, if beagle2 was so cheap they didnt put two or more up on it. I know weight is an issue, but if you can triple your chance of success by adding just 120kilos more weight Id say thats a bargain. I am not as well up to date with the rovers as I am with beagle2 but the overall design looked far more complex than little beagle2. I would love to see them become a success but I cant help the feeling that there are too many things that can break. Lets keep fingers crossed Im wrong. Its the same as with a car with too many extras. Id prefer to send a beetle to mars rather than a BMW 7.
    I honestly hope they tested their stuff as much as you say: they might need it.

    I was under the impression that there are so many probes this time because Earth and Mars came very very close last summer. Their relative position was probably favorable for plotting an easy trajectory to mars.

    I could be wrong though. Could someone plz verufy this?

    Radiated energy decreases with the square of the radius.

    It might not be "much farther" away from the sun, but it receives much less energy from it. Hence - bigger solar arrays, or smaller power loads.

    It's not the specifics of my idea that matter. What really matters is involving the people. Make the simple man your ally, not an outsider. It's that simple man that creates the wealth that, in the end,is behind space exploration. That wealth can increase dramatically if there's exccitement and enthusiasm. I use this simple technique in my management activities: make people your allies by explaining them their part in the big picture, making them feel involved. (My other technique is discipline ;o))

    I have not heard of the Mars Sundial, my bad. That doesn't necessarily change the point I was trying to make.

    You said "It does seem that they would have been better off waiting for the MGS imagery before actually landing... ;-)

    Sometimes even the most obvious things are only clear with hindsight.
    "

    This may not have been possible. Three points:
    1) Mars Express was designed before the Beagle 2 was agreed to be attached. Since it had to do a correction after entering orbit to make its orbit a polar orbit, it probably wouldn't have had enough fuel to do so with the Beagle 2 still attached.
    2) Since the landing area is an ellipse with the major axis parallel to the direction the craft is moving, a polar insertion would probably be unacceptable for the landing area.
    3) Additional fuel would be required to decelerate the Beagle 2 out of polar orbit

    Obviously since the Beagle was a late 100 kg addition, the idea of adding additional fuel is impossible due to the weight constraints. You can always wait for additional information before you attempt to land your spacecraft, but by then it might be year 3000 and the argument would be over whether the new 1 mm resolution camera is accurate enough to land a spacecraft.
