ESA Aiming for Martian Probe in 2011

allanj writes "According to the BBC, the ESA is set to send a robotic probe to Mars around 2011. They apparently want to return samples of Martian soil with the probe - cool idea if it works better than Beagle 2 did..." From the article: "They still require a great deal of further detail and the agency's member states will also have to sign off the mission. Ministers will have their say when the Esa Council meets in December."

    Today the Council of Elders confirmed the rumours that the sinister blue planet third from our star is planning to send yet another one of its mechanical invaders.

    K'breel, speaker for the Council, stressed that there was no cause for alarm:

    "While it is true that the blue planet is sending another invader, we are confident that we can deal with the situation. This particular invader seems to be of the same design as the one we destroyed over one standard year ago, so it should be vulnerable to the same tactics. Even failing this, it should be no problem to isolate the invader and keep it from any contact with citizens...a policy we have developed and upheld ever since the blue planet initiated hostilities."


    When questioned whether the rumours that the blue planet was almost covered in poisonous, corrosive di-hydrogen oxide, as many independent scientists have asserted, had any validity, K'breel declined comment.

      Different ideas, different builds. Why do we have Windows and Linux when the programmers could work together? And the ESA and NASA are very different. I remember in Industrial Psychology we studied different systems of buisness. In Europe, they work as a team and are credited as members of a team. In the USA people get credit for outstanding work individually, not a team. So it is interesting to see how this plays out. The motivations are different, the dynamics are different, and the probes that are built will be different. I think there is something to be learned here.

      Plus, if it was just NASA, we would have a space shuttle that never changes. Maybe some new ideas would make NASA reconsider their designs.

      If you assume that you're going from Earth's orbit to Mars' orbit (1AU to 1.5AU) straight out (about 75 million km), then it would indeed take about 48 hours the way you describe.

      In the real world you also have to get out of Earth's gravity, fight against the Sun's gravity, and then push against Mars' gravity to avoid crashing.

      You also have to consider that when leaving Earth, you still have Earth's tangential velocity, which is much greater than Mars' (via Kepler's third law). The best way to go from Earth's orbit to Mars' orbit is a Hohmann transfer (about 400 million km). Say an object in orbit needs to go to a higher orbit. You don't fire your thrusters against gravity, you fire them in the direction of your orbit. Of course it's impossible for a chemical rocket to fire that long; the heat buildup would destroy the engine. That's why all current missions get the necessary velocity in one quick push.

      And of course the new technologies will be better, but they either don't exist or they are being tested (SMART-1 had several problems in it's 14 *month* journey to the moon). While NASA hasn't launched an ion-drive mission they most certainly *have* tested such engines, as well as the nuclear thermal propulsion engines. The problem is, as I said, economics. There's absolutely no reason to get a scientific mission to mars in a two week timeline.

      If you accelerated as 9.8 m/s^2... ...in space with an ion drive

      Unfortunately current ion drives are *nowhere near* powerful enough to do this (Wikipedia mentions accellerations in the order of a milli-G). So the current ion drives are a really efficient way of moving stuff very slowly, but a lot of work needs to be done improving the amount of thrust they produce. Ion drives are certainly well worth thinking about for interstellar missions though since they are efficient enough to be run pretty much non-stop instead of chemical rockets which you fire at the start and the end of the trip and leave turned off for the rest of the time. (When you're talking about missions in the order of several years then leaving a milli-G thrust running non-stop would get you there faster than just a brief (but violent) accelleration.)

      Use a nuclear fission engine (that the navy has years and years of experience running) to heat plasma and you'd have no problems completing the above scenario.

      Nice in theory, but if you try and launch something the size of a submarine reactor into space and something goes wrong you could end up scattering an aweful lot of fissable material over a large area. I guess since the reactor will be brand new the vast majority will be Uranium (a lot less toxic than Plutonium) but it's still not a good thing.... Of course I have absolutely no idea how the amount of energy required to run a reasonably powerful ion drive would compare to the amount of energy required to run a submarine.

      Using an electromagnetic plasma bubble it's possible to capture the solar wind to propel our craft.

      I haven't been able to find any figures suggesting what kind of accellerations might be possible with this technology - how does it compare with (current) ion drives?

It seems like there are two very important technologies that we need to develop more of in order for our space efforts to "scale": better propulsion technologies and better autonomous vehicle technologies. Any expenditures that don't help those two goals is just a one-shot benefit, rather than a real contribution to making us a space-capable species.

    On the propulsion question, it seems like their plan is to get enough fuel to achieve Mars escape velocity up to Earth escape velocity to get it to the surface of Mars in the first place. It sounds like this is heading towards being just an enormous amount of rocket fuel moving back and forth. I don't see any real advancement in science in us trucking around gargantuan loads of the same old fuels. Sure, it's very expensive and takes a lot of resources, but it's still just rocket science, something we've been doing for decades.

It seems like to do a manned Mars mission you need to get enough fuel to the surface of Mars to a) support all the surface activities there and b) lift the astronauts back off the Mars surface and c) lift the astronauts back off the Mars surface. Yes, b) and c) are the same; I don't think anyone would propose sending astronauts over there without a backup lift-off plan. But anyway, when you add up all the fuel in a, b, and c, plus crew habitations and science gear, you end up needing many tons of stuff on the surface of Mars, and it costs something like $10,000/pound to get stuff off of Earth so just the fuel costs alone are going to be mind boggling, and in the end we haven't developed anything new. Just more big rockets.

    It seems to me that the whole thing is a pointless waste unless we develop methods of producing fuel on Mars itself, so round-trips can become a more routine thing and we can start thinking about larger probes even further afield.

If a decent water source can be found (which is becoming more and more likely), they wouldn't even need to take the H2 with them.
