We talked about it everywhere ...

France Inter even devoted part of their head to the square yesterday.

You could see that they didn't know what they were talking about: I mean plants.

The objective is to feed the 6 astronauts who on Mars with this question asked by a scientist: how many hectares to feed 6 people?

Didier you could apply as a scientific advisor for market gardening

Good question / remark!

I improved the title let it be more general!

All that is empty ideas!

Ah no there is no air in space first!

Ideas in a vacuum, there ok!

You are quite right! However, those who cogitate on this kind of projects do not lack air!

I do not know if the subject can extend beyond these few jokes even if we can always recreate in the space of the growing conditions but at what price.

This has already been done and successfully consumed.

But it was for the anecdote and as I heard the program to raise the level of lack of culture (it is the case to say) of the speakers.

If the plant germinates 99 times and dies 99 times what interest?
We can even push (it is the case to say) further: if it grows to maturity but never gives fruit what interest.

In this case the only interest of a plant is its consumable production and there we are very far.

If it is only that proves that the gravity of the moon does not prevent from germinating (which is undoubtedly not harmless for the specialists) but that in addition it will take greenhouses to recreate favorable conditions there to make grow plants on the moon or on mars, basically the same as what we could have in Siberia or Antarctica to grow vegetables in any season: wow what a discovery

It is for the future of humanity ... they say!

We must sell the concept and it is much more attractive than "narcissistic itching of all technological power"!

Is the red planet conducive to cultivating green spaces? At Wageningen University in the Netherlands, researchers artificially reconstituted the soil of Mars, using samples brought back by the Viking 1 probe, to grow flowers and vegetables there.

The results of the study are surprising to say the least: plants seem to grow better in the recomposed soils of Mars than from the soil of our dear planet Earth. To explain this phenomenon, Wieger Wamelinck, the research coordinator, recalls that “plants need phosphorus, calcium and potassium. We find it on Mars and in the soil of the Moon, but the concentration is much stronger on Mars and that's why it grows so well. ” On the other hand, "the earth used for the earth's soil looks like river soil, quite poor in minerals", which slows plant growth.

Once this postulate is stated, there remains a major problem. The soil of Mars is very rich in heavy metals, the plants produced are therefore very toxic. So that "we can grow tomatoes, but they would contain so much heavy metals that they would be toxic and inedible", says Wieger Wamelink

We are still very far from the idea of ​​terraforming!
If we go to Mars it will only be "for sport".
