Mars Exploration

I dont think a manned misssion is feasonible for humans. The stakes are way too high for minor problems turning into big ones fast. Mars is at best dangerous to life as we know it. Exteme cold, extreme radation, no liquid water co2 is a solid. A rescue mission could never be attempted not when it takes 3 years to get there let alone orbit correctly with no failures ever in any equipment you take what you have thats it, no spares. If one thing with rockets and systems that support them they break go kaput or explode. Robots can take the punishment. We humans need air , water, protection from radation and solor flares.
This is the number one Hitch ..>>>FUNDING! No one can afford the major cost probally 10 times what a robot mission would cost.
Why go to mars theres nothing there its a very dead world. Another big problem is food self sufficient with nothing to go wrong with food production/oxygen. Is martian soil able to grow our alien seeds. Too acid too neutral or some other problem could doom the mission.

A manned mission to Mars is well past its due date.

Most of the decent science fiction writers have us on Mars, living there setting up small communities and even migrating there.

It took many years to realise Jules Verne's From earth to the moon and maybe even longer to realise some of Philip.K.Dicks and others imaginings of settlements on Mars.


I would defiantly disagree with the hypotheses that a manned mission to Mars is not feasible.

The odds I feel will be overcome, maybe not by America but China.

In my mind I feel we must master living on the Moon before venturing out to Mars. And a manned Mars mission needs to be a substantial effort and not just three or four astronauts that land, do a couple of days of exploring and then pack up and come home.

I really doubt now that I will ever witness images of humans on Mars.

Our martians {us} would be stranded for 3 years. They need 3 years of food, oxygen,water and food production. Food production must work on the base with no hitches thats their oxygen production. Who would pay for this aint no way in the forseeible future that our economy could ever do it. Radation protection and advance warning system needs to be in place. Water would be a big problem its duel purpose as radation barrier and drinking can it be dug from the dirt on mars its harder than concrete.
Curiosity i hope works for years if it survives its landing.

I totally agree on going to the moon but really why, because its there dont cut it. The funding well is dry. Manned anything just costs enormous amount of cash just to get off the ground. The apollo days are gone and all the people that worked on the shuttle program are outta work. We live on the only reliable spacecraft we could find. The milkyway and the local group of nearby galaxies are going towards the Virgo Cluster with a collision course for Andromada. In 3 billion years the inflence of the Virgo cluster will tear the milkyway apart. One thing we do have to figure out is why we are zooming towards the virgo cluster at 3 million MPH, whats drawing us and local galaxies that fast. We will have to relocate sometime in the future to more stable areas.

What's drawing us together is "Gravity" the warping of space and the fact that objects move to their lowest energy state (i.e. downhill)

What I find really bad is that weve detected planets out to 15000 lightyears and exactly "none" of them are habital planets. Anything over 5 lightyears is well beyond what we can travel to. This is a very bad thing in case we do have leave earth where do you go. You need breathible air water and food to last for 50 generations to get there one way and thats it, were done no way home and maybe a world incapible of sustaining our lifeform.

Gravity all local galaxies are pulling away from us in different directions but in general something other than local group of galaxys is pulling us and the local group that direction at 3 million miles an hour. Something we havent found it bigger than any group of galaxies. A big mystery dark matter /dark energy who knows but its in quantum physics somewhere.

in case we do have leave earth where do you go

Good Ole spaceship earth, this lifeboat amongst the stars id going to last for another 3/5 billion years. 3 if we get clobbered by a collision with Andromada, 5 billion if the sun starts to die. At that time we die right here as a race our entire being lost to time. We have to find something as soon as we can. Like one of you said several billion people wont be able to go. We must continue searching. I think since globular clusters are the most stable oldest stars we know about. There are over 120 globular clusters in the milkyway.Why are these stars the oldest in our galaxy another mystery.

Have you seen this yet? A Dutch company plans to colonize Mars by 2023. They are going to make it a reality show to fund it. I'd watch.

There may not be air in space but there is an Air in Space Museum.

When I see companies like this, it gives me a little bit more hope that we will get to Mars sooner rather than later. Of course, it's going to get critized but I don't care. At least there are some people out there with imagination and desire to do something.

Let's get there....and get there soon!

I think this group of people are in the wishfull thinkers they need major funding. Of all the modules that need to be in place with no problems for 3 years. They are 20/ 30 years away from any feasibility study.

Im sure you guys and ladies have heard of Maccio Kuca hes does history channel stuff and is a physcist. I watched a video on a lecture to terraform mars, Had to giggle. Since mars does,nt have a magnectic field how the heck are you going to hold an atmosphere. Its atmosphere now it tenious at best like 100000 feet up on earth. Mars couldnt be terraformed god only knows how you are getting all that equipment there. Talk about a funding shortage they better start selling donuts.These phydcists make big bucks on these lectures boy they get mad when you trip em up.

Terraforming Mars will be a formidable task and even though it has only a very weak magnetic field for protection it is also farther from the sun making the solar wind somewhat weaker. Scientists have calculated that a dense enough atmosphere can be formed requiring continuous generation of the necessary gases. But as difficult as making Mars habital is the alternatives are even more difficult. Like bulding an Ark ship to send colonists to the nearest star with liveable planets. If it is important enough to provide humans with a second place to call home in the event of an unstoppable natural catastrophy a way will be found to get the job done.
