Actually it depends on the depth. Gravity is a function of the depth of the planet, the more down you go the weaker it becomes.

Edit: what I sad is not exactly correct. It's not a linear function of the radius of the planet, but it depends on the composition of the planet. In the picture below you can see the strength of gravitational field inside the Earth. However if the planet were hollow than inside it the gravity would be indeed 0. Also in the center it's zero.

I was just making a sarcastic comment

A ok
Then my answer goes to tuanhung's question.

China prepares to grow vegetables on Mars

Chinese astronauts are preparing to grow fresh vegetables on Mars and the moon after researchers successfully completed a preliminary test in Beijing, state media reported.

Four kinds of vegetables were grown in an "ecological life support system", a 300 cubic metre cabin which will allow astronauts to develop their own stocks of air, water and food while on space missions, Xinhua news agency said Monday.

The system, which relies on plants and algae, is "expected to be used in extra-terrestrial bases on the moon or Mars", the report said.
Participants in the experiment could "harvest fresh vegetables for meals", Xinhua quoted Deng Yibing, a researcher at Beijing's Chinese Astronaut Research and Training Centre, as saying.

"Chinese astronauts may get fresh vegetables and oxygen supplies by gardening in extra-terrestrial bases in the future," the report said, adding that the experiment was the first of its kind in China.
China has said it will land an exploratory craft on the moon for the first time next year, as part of an ambitious space programme that includes a long-term plan for a manned moon landing.

The Asian superpower has been ramping up its manned space activities as the United States, long the leader in the field, has scaled back some of its programmes, such as retiring its iconic space shuttle fleet.
In its last white paper on space, China said it was working towards landing a man on the moon -- a feat so far only achieved by the United States, most recently in 1972 -- although it did not give a time frame.

China's first astronaut Yang Liwei said last month that Chinese astronauts may start a branch of China's ruling Communist Party in space, state media reported.

"If we establish a party branch in space, it would also be the 'highest' of its kind in the world," Xinhua quoted Yang as saying.
The astronaut was launched into space and orbited the earth aboard the Shenzhou 5 spacecraft in 2003.

Why don't you put this project on kickstarter.com or gofundme.com ???

[bitreaktor]

what i am curious about is more philosophical matter

if a person is conceived on mars is it still an earthian or is it martian?

Is it even same species or did we just created an intelligent extra terrestial live ?

are we gods?
and we can say :

"My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jews. But now my kingdom is from another place." John 18:36

are there jews on mars?

an shit like this ahahaah

Any plant production surplus will be stored as emergency rations for the second crew, and for other emergencies.

Don't think that is possible. You can't grow plants with just water and sunlight. Plant Production Units on earth require nutritional input by the operator and I don't think that is something that can be "found" on Mars. Be it hydroponics, aeroponics, or conventional methods of growing, essential minerals and nutrition will have to be shipped from earth because I doubt it exists on Mars.

it's not like you need tons of them so whats the problem

after a while you can propably create them on mars

No, you probably wouldn't need tons of them but I'm just saying that its wrong to say that they will be producing their own food (independent of shipments from earth). And unless these nutrients are found naturally on Mars, they will always have to be shipped from earth.

[AnOldBlackMarble]

They only need a starter kit. We don't eat the entire plant from root to stem to leaf. Those would be decayed back into the Martian soil, as would the human waste. So just like on Earth, the death of previous life will be the nutrients of the following generations, all "activated" by the light of the sun.

[EdgarsSTAR]

And what about the meat products? Are we going to have chicken, pig farms on Mars? And how are we going to get them to Mars? Okey I understand we can transport chickens while there are in the eggs....., but still what about larger animals?

Potassium, Sodium, etc are all available from Martian soil, processing those locally would be far easier than shipping them from Earth. Besides which, human waste products would be readily available and the whole process would operate cyclically.

Eventually, but not on the first day. First we need a habitat for them, and enough "green Mars" to grow the vegetation to feed them. Then we could take fertilized embryos only, and grow them in artificial "wombs" and then "birth" them onto Green Martian soil. It is easily doable today.

[erbse]

Indeed. It's all easily doable today. And will be even more so 10 years from now. So don't you worry, darlings.

Martian and it will be just another "coloured box" for idiots to put people in, like nationalities, "race" and other such BS.

Same species. What sort of question is this?!

Not at the moment, but soon. Either way, see my opinion on coloured boxes above.

[CanadianDemon]

Lichen would grow on Mars if we just plopped 'er there and waited.

with even current technology it is possible to "grow" meat without need to raise an animal

so keeping live animals would be unnecessary and a waste of resources

well it is reasonable to think that to raise a healthy child on mars you may need or want to change his DNA code
(nature would propabbly do it if you gave her 100mln years )

as diffrence beetwen chimp DNA and human are only 1-2%
would it be still homo sapiens sapiens
or maybe homo marsianus

and you have several races even on earth depending on envioroment / continent (dont want to sey how they look like) they live in
so i wouldn't dismiss this question as we creating a totally new world and they surley will appear in future

not that i give a fuck about classification
just trying to make it more intresting

Mars One Issues Requirements For 2013 Astronaut Selection



AMERSFOORT, THE NETHERLANDS, 08 JANUARY 2013 - Mars One, a not-for-profit organization which plans to establish a human settlement on Mars in 2023, today issued the base requirements for its pending Astronaut Selection Program. This establishes the first step toward the global selection process which will commence in the first half of 2013.

Unique to all other space exploration endeavors before it, Mars One is opening the astronaut program to anyone on planet Earth that meets the base criteria. It is not necessary to have military training nor experience in flying aircraft nor even a science degree. It is most important that each applicant be intelligent, in good mental and physical health, and be willing to dedicate eight years to training and learning before making the journey to his or her new home on Mars.

Norbert Kraft, former Sr. Research Associate at NASA and Chief Medical Director for Mars One states, "In my former work with NASA we established strict criteria for the selection and training of astronauts on long duration space flights. Gone are the days when bravery and the number of hours flying a supersonic jet were the top criteria. Now, we are more concerned with how well each astronaut works and lives with the others, in the long journey from Earth to Mars and for a lifetime of challenges ahead. Psychological stability, the ability to be at your best when things are at their worst is what Mars One is looking for. If you are the kind of person that everyone chooses to have on their island, then we want you to apply too."

Applicants need to be at least 18 years of age, have a deep sense of purpose, willingness to build and maintain healthy relationships, the capacity for self-reflection and ability to trust. They must be resilient, adaptable, curious, creative and resourceful. Mars One is not seeking specific skill sets such as medical doctors, pilots or geologists. Rather, candidates will receive a minimum of eight years extensive training while employed by Mars One. While any formal education or real-world experience can be an asset, all skills required on Mars will be learned while in training.

Suzanne Flinkenfloegel, Director of Communications at Mars One offers, "Well before the official Astronaut Selection Program, we received more than one thousand emails from individuals who desire to go to Mars. While they may not yet realize the incredible challenges that lay ahead, this show of support for a global selection campaign is so important to us. We are working hard to launch our selection campaign as soon as possible, to open the doors to everyone who aspires to do something tremendous in their lifetime."

The Mars One Foundation will employ the astronauts during their Earth-based training and life on Mars and will be the manager of the simulation bases on Earth and the human settlement on Mars. Eight robotic cargo missions (2016-2021) will establish a habitable settlement which will welcome the humans upon their arrival to Mars. The final Astronaut candidates will be selected from the global applications through a combination of critical review by Mars One experts and a global, televised program which ultimately selects which set of four astronauts from those assembled will be the first to go to Mars.

What if they started out by harvesting the Asteroid belt for minerals that they would add to Mars to boost it's diversity of mineral content. Then the next time a comet comes into the solar system, they harvest that for water for Mars.

I wonder if some of the other celestial bodies in the solar system might hold water, even if frozen, that can be harvested for use on Mars. I believe Europa does, so maybe it can be harvested of it's water to be used on Mars. What would be even better is to find a whole huge chunk of ice that they could make crash into Mars. Something the size of Texas...LOL

The idea being that you need a lot of water on that planet if it is to become a truly habitable place.

I'm not sure it is really feasible though as this project seems to forget that Mars does not have a powerful magnetic field like Earth's which not only helps hold in the atmosphere, it protects life from radiation.
