      You'd want to be closest when the astronauts were coming back. It's (relatively) easy to launch them with lots of fuel and supplies to get there, but it's simply not possible to launch similar amounts from the surface of Mars. Ideally, the astronauts would be coming back around August 27th, not launching on their way there with a long journey back.

        This is not so simple. You do not travell to Mars from Earth and vice versa in a straight line. It's more like a spiral which means you will circle the sun at least once to reach Mars. I think the most important thing is the turn around time of the communication. So, you want Mars to be closest when the astronaunts on Mars, because communication turn around is less than 7 minutes in such a case.
        • *sigh* Spiral= bad.
          holman orbit=elliptical= lowest energy orbit= happy engineers because you don't have to waste all your mass on fuel. And for an elliptical orbit you'd still want to go at about the time Mars is closest- you want to treat both Mars and Earth as the focii for the ellipse.
        • It's more like a spiral which means you will circle the sun at least once to reach Mars.

          While circling around the sun (sling-shotting) works great for unmanned probes like Voyager, it is not feasible for a manned mission because it adds time to mission schedule. More time in space = more fuel requirements + more supplies for the astronauts >> more fuel again.

          Communications will always be delayed so difference between a close Mars and a farther away Mars will be miniscule. The distance to travel is

      • Have the return craft circling the planet, so you don't have to takeoff with so much fuel.

        It is still costly (take the fuel all the way there), but much less.

    • It's no accident there are so many Mars missions occurring simultaneously.

      The mass exodus to Mars has been strategically planned over many years to make the best of the closest opposition of Mars in more than 60,000 years.

      Not manned missions, but then again, we arent ready for one yet.

      I have seen what the trajectory for a mission to mars would be like - It makes no difference that mars is closer to earth, because the spacecraft cannot fly in a straight line between the two worlds unless we managed to develop a far more powerful propulsion system. You have to fly in a spiral trajectory around the sun that would only intercept mars after a year, and spend a year or so on the planet to wait for earth to be in the right position for the return flight. You would then leave mars to orbit around the sun, firing thrusters in reverse to spiral in an intercept the earth after another year or so. The total mission time would run from 3 to 5 years.

      That is why going to mars is so much harder than going to the moon. The astronauts have to be kept alive and sane for years, not weeks as was the case with Apollo.

      If you want to minimize fuel use, a straight line is not the best way to change orbits. You want to time your launch so that a minimum-energy trajectory (http://scienceworld.wolfram.com/physics/HohmannTr ansferOrbit.html) intercepts Mars.

    I think that, out of all the missions the article mentions, Mars Express [esa.int] is the most exciting. This mission, which is backed by the European Space Agency [esa.int] (rather than NASA, as the article implies), carries the British-built Beagle 2 [beagle2.com] lander, targeted at looking for evidence for Martian life, past and present. Beagle 2 (named after Charles Darwin's ship) is far more sensitive than the old Viking Missions [nasa.gov], which were the first (and so far, the only) missions to look for life. It's worth noting that the more-recent Pathfinder [nasa.gov] mission was a proof-of-concept for the two upcoming Mars Exploration Rovers [nasa.gov], which are for geological surveys rather than life searches.

    One partcularly cool feature of Beagle 2 is its "Mole [beagle2.com]", which can crawl across the surface (at 1cm/s) and burrow imto the ground or under boulders. The Mole will be able to take samples from locations which the Viking landers couldn't reach; these samples may provide conclusive evidence that life once existed on Mars.

    Mars Express, carrying Beagle 2, is due to blast off from the Baikonur Cosmodrome in Kazakhstan on June 2. Fingers crossed!

    Mars is all well and good, but I really think we should be focusing on the Moon! Mars is so much farther away it takes half a year to get there. The Moon, on the other hand, only takes two days. And if anything goes wrong, the Moon is actually close enough we might be able to get there in time to do something about it.

    I don't see a problem with sending "orobes" to Mars, because it's always good to know something just for the sake of knowing, but knowledge of the Moon is much more practical. We've had the technology for decades to establish a Lunar colony . Why didn't we? There's water, and therefore oxygen, and most of the metals you could possibly desire all on the Moon. We should establish a Lunar colony first, and then worry about manned missions to Mars.



    A space elevator wouldn't hurt either.
    • We've explored less than 2% of the ocean floor on this planet so far. Why go to the moon or mars when there is all that to explore first?

      Or we could shrink ourselves and explore other people's inner ears!
    • And to cut the costs for transporting to and from the moon, we could use a system with three or four huge spaceships that would never land, but rather travel in a similar trajectory as the Apollo ships did. Then, when you want to send something from Earth to the moon, just launch it to dock with the spaceship. Kinda like having trains where you throw the stuff onto it without the train ever stopping. Then when it arrives at the moon, just undock the module then land it on the moon. This way you could transp
      • you would still have to accelerate the stuff we want to send to the moon to the same speed as the 'trains' that goes inbetween them, otherwise there will be some, eh, unpleasant, sudden acceleration/deceleration when the ships hook into each other.
        • Yeah the "trains" would have to adjust its speed and trajectory when they know how much the total mass will change, probably before it goes around the moon. But I wonder if the whole arrangement still wouldn't be cheaper after all?
          • you would still have to use the same amount of fuel though, since it's the acceleration/deceleration that needs it. THe trip between the earth and the moon is 'free' so to say, you just glide along. Mind you if you're moving people, youwouldn't need to facilitate all the stuff that's needed in the launch vehicle, all that can be in the 'trains' which can be reused.
      • The cargo still has to be spaceworthy in order to get onto your transporters, you still need to get enough fuel into orbit to provide the kinetic energy to transport each piece of cargo to the moon. In addition, you have to get your huge spaceships into the required trajectory. So what is the point in the huge spaceships?
        • My idea, which may be wrong since I'm not a physicist, is that the big transporters would be set on the 8-shaped trajectory only once. It could use the gravity of the moon or earth like a slingshot to accelerate, in addition to that it would need fuel to adjust its trajectory. Could this work in any way? Would it be economical?
          • You're missing the point. You either have to accelerate the payload to the same velocity as the spaceship, in which case it will make it to the moon on it's own, or you just put it in the path of the space ship, and let the momentum of the spaceship accelerate it. In the latter case, the spaceship loses energy, and eventually crashes into either the moon or the earth. Either way, in order to keep the system working, you have to use the same amount of energy as you would to just send the payload to the mo
            • Well you are right of course, and I didn't think things through completely, it seems. Heh.
            • The ships can gain energy from the gravity fields of Earth and Moon? like how the past orobes got it from Jupiter. If they knew they were going to be accelerating payloads, they could attack the fields more aggressively than if they were just going to sit in a stable orbit ?

    A source close to the Pentagon claims to have seen evidence of a Martian plot to destroy vital U.S. interests around the globe. He spoke to us on the condition that we refer to him only as "Bugs".

    "They have an Illudium Q36 explosive space modulator, and we're the ones who sold it to them" explained Bugs. "Back in the fifties, there was an American company called Acme who would sell anything to anyone. The Martian leader, a looney little guy named Marvin was a regular customer. He's hell bent on destroying the Earth. It's all he ever talks about. Something to do with his view of Venus." Some research into the Acme company seems to confirm Bugs' allegations.

    But Martian Information Minister, Wyle. E. Coyote, told us a different story. "There is no Illudium Q36 explosive space modulator. This is a myth being spread by the evil ones. "Sure, they sold us some rocket powered roller skates, and giant magnets, but we only use those to control the roadrunner population."

  • Because the orbit of Mars is not a perfect circle, Mars, at times comes closer to Earth than others. But, all oppositions are not equal.

    What does circle have to do with anything? The configuration of Mars and Earth orbit is important not the shape of a particular orbit. It is unfortunate how often journalists demonstate complete misunderstanding of basic ideas.

    • Eh?
      If Mars and Earth orbits were perfect circles (centred on the Sun, obviously), then the oppositions would always be at the same distance.

      So if the oppositions are not equal, the orbits can't be perfect circles, QED

      Furthermore, it seems to me (although I haven't done the maths) that even if Earth were any ellipse (maybe circular), and Mars were a non-circular ellipse, then there will always be differing opposition distances -- which is exactly what the article said.

      • If Mars and Earth orbits were perfect circles (centred on the Sun, obviously), then the oppositions would always be at the same distance.

        Even if the orbits are perfect circles, lie in the same plane (as you are implicitly assuming and which is obviously not the case in reality), they would still have different angular speed. That is the year on Mars would be different time from the year on Earth. Therefore the distance between the planets would not be the same all the time.
