An experiment by the Phoenix proves: it is possible to plant vegetables in the soil of Mars

The composition of Martian soil tested with a dedicated instrument on board the Mars lander Phoenix is ​​remarkably similar in its composition to common soil on Earth. The acidity of the soil is also similar to ours and it will be able to be used by the astronauts to grow vegetables

Another exciting discovery from Mars, the Phoenix spacecraft analyzed the Madamiami regolith and it turns out that it contains minerals that are also very common on Earth, and that the acidity of the soil is not a factor that could hinder the prosperity of life. These new findings came after a preliminary analysis of the regolith test at the Phoenix "wet lab" facility known as the Microscopy, Electrochemistry and Conductivity Analyzer (MECA).

Although much data still needs to be collected, traces of nutrients have already been discovered. This, together with the indirect discovery of water ice in the meantime amazed the scientists of the mission, who say that the result is like winning the lottery.

The impactor performs the first-ever analysis of wet chemicals on a non-Earth planet, and these results may bring us closer to answering the question "Can Mars support life." The digging shovel took a sample from the soil on the surface of the ground and from a depth of 2 centimeters, transferred the sample to Mecca, where the analysis was performed. The first results from the two-day wet experiment are starting to trickle in and the scientists are excited about them. "We are inundated with chemical data," said Michael Hecht of JPL and the principal investigator of the MECHA instrument.

The salts found in the soil sample include magnesium, sodium, potassium and chlorine, indicating that these minerals were once dissolved in water. The information that these materials are present in the Martian regolith is not new, but the fact that they may have been in water means that they would have been available to living creatures if there were any on Mars. In fact, there is a strong similarity between the mineral content and the level of acidity on the surface of Mars and the common composition of soil on Earth.

It is possible that this will also help the astronauts who will land on Mars. They will be able to use the Martian soil to grow vegetables, albeit under controlled conditions in sealed greenhouses, but they will not have to bring many minerals essential to life from Earth.

As you remember yesterday, we published that the flat northern half of Mars, where the Phoenix spacecraft is at one of its points, was created as a result of the impact of a large asteroid, the size of the Australian continent at the beginning of the planet's life, which left the area at a great depth, and if water was formed at any stages later in the history of Mars , they poured into this vast valley, and turned it into a huge ocean, the smooth ground that remains is evidence of the sediments of earth that were carried to the low places, thus causing the smooth appearance of the northern hemisphere of Mars.

  1. It's annoying that NASA is telling us stories about the workings of the Phoenix. She was sent to find water, and she didn't succeed, the scratches on the ground and the faded white paint prove nothing. And now they are telling us about vegetables that we will grow on Mars.
    It is becoming a nasty habit of NASA not to succeed in its experiments.
    I remember the experiment they did in one of the previous spacecraft to test for life on Mars, but even then the results were not conclusive.

    So NASA, is there water on Mars or not? This is the question!

    Good night

  2. In the meantime I checked and it turns out that as your website address (under your signature) you wrote CNN.COM
    Many spammers use the names of popular websites to trick systems, therefore combining a common URL in the signature with a URL that does not belong to the company in question made the system suspect that it was spam, your links were not the problem.
    Of course I released the comments for you, just so you know for next time.

  3. Yoav, send me the links by email ( and I will add them to your comment.
    If I didn't run a system that filters, even if sometimes it mistakenly considers a good response as a spam response, but the fact that this number is zero compared to the real spam responses that are avoided by the surfers of the site thanks to the system (currently about 42 thousand). It's a small price in my opinion.

  4. Rabak what's going on with this screwed up comment system??? Already 20 times I've tried to send a comment with a link here and the message doesn't go in, what's going on here???!!!!

    In short, search on Google -

    The earth is Mars

    (without quotation marks) and go to the Wikipedia link, this process is called "Ha'aretz".

    Rabak, what an annoying site this is!!!

  5. It also has a professional term
    The transformation of Mars into the land of Terra

  6. Lamotish,
    That's the whole idea, go to the Michael Kisher page:
    In order for an ozone layer to form, the temperature on Mars must first be as high as on Earth (plus or minus). and that the oxygen concentration will be high (from which the ozone will be formed).

  7. Does Mars have ozone?? I don't think so... surely if we go there we will die from radiation!
    So you need oxygen, which is possible with the help of plants and somehow turn the oxygen into ozone...

    moving apartments?

  8. Michael, the page you gave is very interesting.
    It seems very possible according to the descriptions, even if it will take several hundred years to adapt to humans.
    From what I understand from the page, oxygen could be preserved in the red atmosphere

  9. Exciting message from Phoenix,
    Two stars with life on which they can guarantee the future of the human race.

  10. I wonder if they will be able to grow trees there that will produce oxygen (and that the oxygen itself will not escape from Mars)

  11. Here it begins, as soon as they discover something worthwhile there, they will start chasing another star...
    Hope they won't find anything there... The human race is not yet mentally and morally slow ready to reach other planets...

    Solve the problems on Earth first...

  12. The new Pinax vehicle is similar to the previous ones in the sense that it can transport itself across the plain?

  13. exciting.
    Maybe the conditions for sustaining life are more common than we thought.
