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."

    The article says the rover's trajectory has been updated. Is it because they were afraid it would land in a crater like beagle2?

      The expeditions all have very similar purposes, scientific analysis, usually analysing chemicals in the atmosphere and soil/rocks, searching for water, or life.

      It would be really neat if they did find life. That would increase a lot of the space exploration budget, I think.

      Beagle2 landed at Isidis. MER-A Spirit is landing at Gusev crater. So we did a trajectory corection maneuver in order to land in a crater :)

      Seriously, this is the fourth trajectory correction maneuver. We planned for up to six, but we had a pretty good initial insertion from the Delta rocket. The trajectory correction maneuvers are neccessary due to the precise angle at which we must enter the atmosphere of Mars. Too shallow and we bounce off, too steep and we make our own crater. Its like throwing a dart from Earth and having it hit a bullseye on Mars. We can't throw a dart that accurately so we control the dart on the way.

      The Beagle2 and MER rovers have similar science instruments and goals. Both have several spectrometers, a mechanical arm, a rock grinder (to grind a fresh surface on the rock) and stereoscopic cameras amongst other things. Their goals are the same: Look for life or evidence that life once existed. They're also looking for evidence that liquid water was once present on the surface of Mars. The main difference is that the US built craft are mobile on the surface.

      BTW, the first time 3 probes were sent to Mars (MER-A, MER-B, and Mars Express. Nozomi doesn't count since it was launched in 98) was in 1964 when the Russians sent Zond 2 and NASA sent Mariner 3 and 4. Only Mariner 4 returned useful data. Zond2 suffered a failed radio and Mariner 3 suffered a mechanical failure. (In 1962 the Russians sent 3 probes but 2 failed to reach space and the last died en route). The first successful lander was Russian, but if I remember correctly it landed in a sand storm and died before useful data could be returned.

      Well, I've got to get some sleep. Got to get back to work early tomorrow to monitor the spacecraft.

      "

      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.

    The two mars rovers probably have a better chance of success than the (possibly) failed Beagle 2. Let's consider why:
    Beagle 2 was built on a shoestring budget. Many aspects weren't tested to the extent the NASA rovers were. Example: the Beagle 2 parachute was designed in 8 weeks (as I recall; I may be a bit off here) after the original was revealed to be seriously flawed in the late planning stages. because of time constraints, the parachute was not extensively tested. It was similar with the protective balloons. On the other hand, the NASA rovers (which are virtually identical) were tested for years, every aspect tested again and again, as you can see by listening to the wonderful project scientist interviews at http://www.planetary.org/radio/ (a great group of space related radio shows.... gooooooood good stuff). The extensive testing in the NASA Mars Rover missions wasn't cheap, but there is no major flaw that engineers are 'hoping won't screw us up', unlike (possibly) Beagle 2.
