Why Mars?
Phoenix Mars Lander is on final approach now. If you could hitch a ride on the little ship, you would see a rusty red globe looming in the distance, slowly growing. Nothing much will happen until late Sunday afternoon, U.S. time, when the ship jettisons its cruise stage, and goes plowing into the Martian atmosphere. Engineers hope that in a seven-minute period, it will slow from 12,700 miles an hour…to only five. (Take a look, if you haven’t already read it, at Gina Sunseri’s piece.) Landing is a risky proposition, and the mission managers at JPL are clearly trying to keep expectations low. A very similar probe, Mars Polar Lander, crashed in 1999. All of which raises the question of why they try. I invite you to weigh in, as we get closer to Sunday, but here’s one answer, from an interview I did a couple of years ago with Steve Squyres, the Cornell astronomer who is the principal investigator for the twin Mars rovers, Spirit and Opportunity. They landed safely on Mars in 2004, and though they’re clearly wearing down, they’re still going. Squyres and his team say the rovers found clear evidence that there was once standing water on the Martian surface — brackish pools and rivulets, thick with the minerals that make the planet red. That water is long gone — but the rovers both landed near the Martian equator. Readings from orbit show there’s still ice in the soil near the Martian poles, which is where Phoenix is headed. It is set to land at 68 degrees north latitude, which, on Earth, would be like landing in northwestern Canada near the Arctic Ocean. Water, plus time, plus organic molecules — those are thought to be good ingredients for the rise of life, and Phoenix is designed to look for organic compounds. But if the mix is right, does life just…happen? Or does there need to be something more? That, to Squyres, is why Mars is worth exploring, and that’s what we discussed down the hall from his office at Cornell. "Life might have originated on Mars. Did it? We don’t know,” he said. But if you can show that life arose independently on two different worlds, just in this one solar system, it takes no great leap of imagination or faith, or anything else, to begin to believe that life might be common throughout the universe." “And the reverse might also be important?” I asked. “The reverse might also be true. You might get to Mars and find that the conditions were once just right for life. It was warm, it was wet, there were pools of water—and you could search for years and find no evidence of life. “That would be important too,” said Squyres. “It means that life is pretty special.”

It’s a funny thing about mankind: Once the question is asked, the answer *must* be found. At least, every effort must be expended in an effort to find the answer. This is no different than any other question we’ve asked. Since we can do it, we must. As H. G. Wells opined in “Things To Come,”: “Once we’ve conquered all of time and all of space, we’ll still just be beginning.” I think that’s a healthy attitude for any race of beings.

Well said Andy. I think our species needs to move off Earth to survive and to thrive. I think we’re approaching the carrying capacity of the planet now. And if not this century, perhaps next, we will find the need to colonize another world. But, we need newer propulsion and energy technologies to do so.

The robotic mars program is in a little bit of trouble lately. NASA is in a really tight spot with money what with the plan to build two new rockets and return to the moon.
We need some manned capability but I’m a much bigger fan of the unmanned missions.
Posted by: bubba | May 23, 2008, 4:39 pm 4:39 pm
bubba, I’m a fan of both, and both have their uses. Robots can do the preliminary work, but there’s no substitute for a human being to see and to find out the real story about the site being visited. Plus, the human is able to discover what a robot can’t see, and to react to things the robot may not have been programmed for. What would a seismic robot “think” of an alien walking up to the craft, kicking it and walking off. It would see foreshocks, a main shock and several after shocks. If the robot’s cameras didn’t see anything, well a momentous event would go almost unnoticed. I really do believe we need both manned and unmanned exploration.
Posted by: Andy | May 23, 2008, 6:39 pm 6:39 pm
Maybe in the long view. Assuming it can be established that a science-wary population would continue to fund a multi-decade manned exploration effort. Didnt get far after Apollo and the only reason the ISS is still kicking is international obligations. Even if we manage mars within 50 years, there is nowhere else to go without substatial leaps in technology and investment.
But in my lifetime its likely that almost all of the big discoveries will come from telescopes and robotic probes. I like manned missions because they can service telescopes but beyond that it doesn’t really interest me.

Is it really that important to go to the frontier of space when people on this planet are starving? Which is more important? Where is our perspective in life? If you were starving and we could help you become self-sufficient, but we declined because we needed to go explore the galaxy, how would you feel? Is spending billions to search for something that “might” be there more important than a human life?
Posted by: Dave | May 24, 2008, 11:09 am 11:09 am
Dave, answer may be no. But questions begets doubt. Life without reason isn’t special either. When we can measure the heavens and the depth of the earth…scriptures lead me to believe game over.

My dad trains astronauts at JSC, and I personally support JPL’s unmanned missions much more so than manned missions for all of the obvious reasons, habitat modules, etc.
Posted by: Ben Straub | May 24, 2008, 11:54 am 11:54 am
Dave,
If we wanted to help the starving people on Earth, that would be great. But we don’t do it.
I think a society as rich as ours should be able to take care of its own people and explore at the same time.

Our governments are looking for other places to live because we’ll use up Planet Earth’s resources in a few decades, and then humanity is basically screwed.
Posted by: Scott | May 24, 2008, 12:53 pm 12:53 pm
I don’t normally contribute to comments after articles because they tend to be a collection of rants, but this is a good one. Thanks to all who have contributed so far. My take on the discussion is that humanity’s present (the hungry here on earth) and humanity’s future (exploration of space with a view to colonization) should not and cannot be mutually exclusive. It’s like saying should you eat or should you breathe. Without doing one you cannot do the other, or indeed survive at all. We need a government – governments – that can sensibly divide resources between these two essential goals.

great scott! what an epiphany!
how long did it take the all of you geniuses to figure out that this earth is a finite resource ? OF COURSE , we need to conserve ,recycle , be as green as possible ,work towards ZPG for the entire planet , but even at that its a well known fact that the earth and this entire solar system are bound for destruction one day ,even if it is many millions of years in the future.
there still is no time to waste, many problems are still unseen/unfigured ; we are truly in the infancy of space travel so having very long term plan/approach is most important. the job of exploring and perhaps colonizing space/other planets will be a exercise in adaptation and ingenuity ,and many wrong turns will be made along the way , as with the challenger mission . overall though it appears nasa and the esa are generally on the right track ; only time can be the judge of that opining ,however i personally am quite convinced that our survival as a species depends imminently on our ability to learn how to travel to other planets and colonize them , adapting (as we always have ) as we go .

If Mars is a bio-dead end, that’s pretty much it for the next 100 years or more. The likelihood of finding life elsewhere in our solar system is virtually nill. They can talk about Titan, etc., but it’s pointless. The very real possibility will emerge then, that we are alone, very alone. For all the computer analysis and radio telescope projects, there isn’t a single shred of evidence to this day that life exists elsewhere.

Matrix stated it well: human is like a virus, when Earth is polluted and destroyed by humans, they move on and try to plaque and destroy another planet, in the name of survival… if you let them acquire the technology to travel the Space.
Nature will find a way to limit this potential damage and cage humans on Planet Earth alone.

Nature??
Interesting force, this Nature. Sounds like a force of intelligence.
Is it computer-generated? Or, Is it historical invisible beings (recorded throughout history in history texts, mythologies, and scriptures)?
I don’t doubt that there may be forces that a times prevent Humans from decimating the planet (or encourage it, LOL). The questions are; what and who and where these forces are; and then: what are our responses to them?

padme,

Are you saying that you are that way, or not that way, or not Human?
Not all Humans were or are that way (at least not all the time).
However, a lot of times those involved in places of “power” can act without enough restraints and consideration for people and things and nature around them.
Almost anyone with enough “power” or authority can be tempted to not hold to ideals, even as the old saying goes: “Power corrupts”. (And it doesn’t have to be political, military, or economic power either. It can even be personal or interpersonal.)
When Humans learn to hold one another accountable individually, locally, and not to relish despising anyone — even to follow the long-held principles of respect and even Love for the person nearby you — then, in those places, situations and relationships can and may and maybe even will improve.
But there seems to always be someone who holds onto prejudices and lack of respect for others. When we help to minimize their effects on us and on those around us, things can improve.
Love, :)

One more:
If they have the capability of hiding and/or being invisible, as evidence leads people to believe is true right here on Earth, then it is unlikely that we will find a whole lot more elsewhere than we do right here.
Maybe especially if unmanned, as someone suggested earlier.
Our robots and probes might find some evidence of organic life existing or once existing, though.
But don’t expect NASA or the governments to tell us much about it anytime soon.

If I could go to Mars I would probably bring thousand of solar panel that they would almost cover the whole entire planet, execpt that we would need to move there when solar traveling comes out (traveling in space) and probably need to go at 2020 or something. We’ll also need a big supply of water. We could use a gigantic space ship to carry water execpt that the water will dry up so we need thick strong metal to prevent it from drying up.
Posted by: Skylar Fang | May 25, 2008, 7:29 pm 7:29 pm
If the government would spend as much time and money as Nasa uses to land on Mars, toward gasoline substitutes, etc. we wouldn’t be in the crisis we are in right now as far as oil and gas prices.
The landing on Mars is exciting but I think we need to get our priorities in line.

Wow, people went from discussing the possibilities of life on other planets all the way down to the validity of human existence. Life, I suspect, is extremely common throughout the universe. People who equate a lack of coherent radio signals as proof there is no other life forget that until only 100 years ago, THIS planet had no electromagnetic emissions to show there was life on it, let alone that there has been for over 3 billion years.
Life is going to be found everywhere. Whether we can talk with it remains to be seen. An INTELLIGENT species has yet to be found – on this planet or anywhere else. Given mankind’s inherent desire and constant drive to destroy himself, I don’t give our species high marks in intelligence. If there is intelligent life out there, and they have been observing us, do you think they’d act like we would by trying to intervene in a multi-pit-bull dog-fight? I seriously doubt it. We don’t show enough promise that we can live peacefully with the rest of the universe to risk any form of contact.
So, life is abundant, intelligent life will avoid us and because of our homicidal tendencies, we have little chance of surviving our own technology. Interesting viewpoints folks, but this is where my conclusions take me.
Posted by: Fatesrider | May 25, 2008, 8:00 pm 8:00 pm
I think the question is silly. Biochemists can already tell us it’s quite possible for life to spontaneously begin. The odds for it just aren’t that high. The point in finding water on mars is to make sure it can sustain human colonies. Having it’s own life isn’t particularly relevant at this point as it’s pretty obvious any life that could exist would be rather simplistic in form and of little importance. It’s got the same value as drilling a couple miles into the earth to see if there are bacteria alive down there. It has very little significance to science and society in general. I’d rather see them working on putting a base on the moon. Mars costs too much to get to for it to be worth anything for a long time.

Judging by some of the “armchair watchdogs” posting unread nonsense such spening the money for the lander project on allieviating food shortages, gas shortages, and humane suffering, obviously you aren’t well studied on any of the subjects. NASA gets well less than 1% of the national budget. Of that, only a minute amount of that goes toward this project, most going toward aviation research, education, as well as Space Shuttle and Space Station operations, and many other things. The nation spends in excess of 35% just on welfare assistance in this country alone. Perhaps we should all just cease all technological research and fall into a quagmire and join third world nations in their squalor. I am tended not to desire to myself. To allof you that have posted against the project i say, grab a book, go to the NASA web, actually read and learn what it is that you post about before you post rather than blather a bunch of nonsensical prattle.

Someday we need a new planet to live in and that would be Mars if it is habitable. Our population is booming and our planet is leading to total destruction if we can’t control the emerging problems that we face today like global warming, thinning of ozone layer, built up harmful gases into our atmosphere. Awareness is very important in all aspects of life. Everything that we face is a matter of survival. We are finding a way to keep our species like relocating to MARS someday. I am hoping that mars would be the next habitable planet.

Some 600 years ago our ancestors were in the same boat we are in now.
Poorly run goverments expanding populations forced man to send Wooden ships across an unknown ocean.
As Much as anyone may like to complain about the need or the waste of Mars Missions, It is a nessary fact.
At least we will not have to wait 600 years to reap the benifits of exploration that is being done TODAY.
Though I do wish it were a more private venture and govermental.

If you use logic you’ll see that human life away from the source and sustainer of human life(earth) just is NOT possible! “Move off” this planet onto another one? PLEEEEEASE! There’s nothing wrong with this PLANET–it’s the PEOPLE on the planet! There’s not a lack of morals…there’s a lack of people willing to follow morals and be guided by them. the pathetic greed, dishonesty, prejudice of many kinds, rampant stupidity.
The Creator of humanity, which is also the creator of Earth, and by the way–Mars TOO—says he’s going to “cause an extermination from one end of the earth clear to the other end.” -Jeremiah 25:32, 33
You can’t even repair a small issue such as the housing crisis in ONE country let alone on another planet. Inequality in so many areas that it’s pathetic to even THINK about putting life on another planet.
The biggest problem with humans is the inability to solve problems between themselves! You worry/complain about skin color, facial features, languages, body shapes—if someone looks at you more than 3 seconds–it’s “Kill or BE KILLED!”
Global warming? Famine? Pestilence? Death? Who started all of these–and answer honestly. Science is going to “fix” the problems? Are you CRAZY!??? Do you see what happens each time a “discovery in science” is made? ANOTHER problem arises!!! It’ll be like wanting to fill up the Grand Canyon—to move the quantity of dirt necessary you’ll need special equipment; where will the dirt come from? Let’s take it from Africa’s deserts. Do so—and you’ll create a problem sooo big you’ll reverse any “progress” that’s been made in the name of “humanity”. You’ll leave a hole bigger than what you are trying to fill.
Move to Mars? Are you crazy? A necessary assignment? Are you silly? START life on Mars–with what race, what nationality, what religion, what industry? You’ll kill the planet just TRYING to start life there!!
When God starts his destruction of the wicked, evil, and stupid people here on earth, He’s going to target those that essentially said that HE was wrong with putting life here on Earth—instead of Mars. Let me tell you this—I will NOT want to be in your shoes. As the Bible says, “Ten thousand will fall by your right side, and ten thousand will fall by your left side. To you no harm will come near.” -Psalms 91:7
Good luck on GETTING to Mars. You better hope you DON’T make it there.

What a total and complete waste of taxpayers’s money, when people in our own country are living in their cars, losing their homes, and moving in with families, because our government would rather waste billions of dollars in NASA, than help their own citizens HERE AND NOW in their own country.
I agree with another blogger…for those who INSIST on space exploration…let it be privatized, rather than funded by taxpayer’s dollars.

i find the most interesting note on this mission is the statement nuclear powered.exactly what does this mean?.what we really need in our society is not wether there is or was water on mars but a nucler powered moter,or a nuclear battery or both.every thing that is in our homes or on the road will one day end up in the garbadge or a museum.every thing,bar nothing.i can see a hybrid auto in a museum next to dinosaurs,circa 2008,what is neccessary to preserve our economy and our quality of life is not the knowledge if there is water on a piece of dirt millions of miles away but a nuclear device that will turn wheels.this forth of july when gas is god knows what you can sit home and look at the four walls and tell your family its not important that we have a holiday, what is important is the fact that we are looking for water on a round piece of dirt millions of miles away.i hope that the nuclear power that is used in this contraption will develope to a point wher it will be used in a practical manner,the ability to turn wheels.eventually the human brain will develope such a device. i have absolutely no doubt about it.look back, see where we were with anything, see the progress?,the human brain is the real tool to the survival of the human race and a survival of a decent standard of living which demands that we are able to have a device that will turn wheels and take us away once in a while from the four walls so we dont go crazy.our economy is fading do to the cost of nothing more then the cost of turning wheels.

i am sure there are many people out there who will swear that i am nuts.really,i think this is a backward society, i think that the idea to turn wheels by using oil belongs in a museum. i have no doubt that someday we will be thought of as a society in the same way as people think of men in the stone age.the real waste is not the waste of few hundred millimn bucks, the real waste is the talant, skill, and brains that could have been used to develop the ability of the human race to turn wheels with a practical source of energy.an atomic powered moter or a battery.right now we are dancing around the mulberry bush,applying band aids, solar [etc]which are indicative of our lack of know how and technology that will really solve this so called energy crises.what we really have is a car going the wrong way down a one way street.what we need is to chart a course with the best brains in the world,yes i said the world to produce a nuclear devise that will turn wheels.sure there are problems there alkways are but we have a tool its between our ears, lets use it to get on the track thats going to solve our problems not take us out in left field. To get results that really add up to less then a row of beans. sure its great to see this marvelous accomplishment, put it next to a nuclear moter or battery, and tell me which would you rather have?.
