ESA Aiming for Martian Probe in 2011 131
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:
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.

very bad thing. NASA has has spectacularly
disasterous luck with its contractors (mixing
up ISO & Imperial measurements cost a Mars probe),
while the ESA nearly lost all data for their piggy-back
probe to Ios (due to uncalculated doppler effects
on data baud rates).
Seems to me that combining efforts may more likely
combine the worst failures of their perspective

A sweeping and absurd generalization. Consider the wildly successful Spirit and Opportunity missions. Are you suggesting that anything other than excellent engineering teamwork and program management have made these missions what they are?

There is a weight[1] limit on all current rockets, which depends on the destination, how fast you want to get there, other such factors. Thus if the ESA and US consider a mission that needs and entire rocket launch itself, there is no point in coperating because in the end much will need to be duplicated.
Another reason to not coperate is it makes for fault tolerance. Most missions are one offs that will never be run again (sometimes two are three offs). It takes to long to get a mission going and so l

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 also doesn't get us any closer to manned missions. 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.
NB, I am not a rocket scientist.

You'd think the poster would RTA. The 2011 mission is a rover mission.
In addition to the rover project, they also reiterated their support for an existing proposal - a "Mars return" mission, sketched for 2016, in which various space powers would pool their resources to send an unmanned probe to Mars, take soil samples, and bring them back to Earth. [spacedaily.com]NASA is already considering [nasa.gov] a sample return mission prior to the 2016 timeframe. I am not sure what plans there are for international collaboration.

How is researching for new weapons a way of helping people on this planet? Or funding the armies, navies and air forces that use them, how does this help anyone? Here's another question: If we stopped doing what some people think unnecessary, would we then begion to help the poor and the sick and the homeless? Of course not, because less money for peaceful science and colonisation means more money for military actions and other bad things.
Why do we do it? Why do we wish to explore beyond our horizon, why do we wish to find new worlds to colonise? Maybe it widens our horizons. It gives us answers to ancient questions, it tickles our imaginations, it gives us hope. Should we rather stay here, to stagnate?
I'm certainly not saying that we shouldn't solve our problems here too. We should. And I believe that to do so we need to stop living in fear of each other and ourselves, we need to stop fighting each other and start to cooperate for the good of everyone. Sadly not enough people in power want this to happen.
