Navarro Gonzalez believes that people should take further actions to explore life on Mars. After all, so far, there is no experiment or research to prove that there is life on Mars. What can only be confirmed at present is that organic compounds do exist on the surface of Mars. It is reported that in 2009, NASA will plan to build a Mars laboratory, hoping to find the existence of microorganisms on Mars. The European Space Agency also plans to launch a Mars exploration program called "ExoMars" in 20 1 1 3 years. 1975, NASA carried out the Viking Mars landing exploration plan, and launched two Viking Mars probes successively, and successfully landed on the surface of Mars in 1976. Viking carried out a lot of photos and investigations and worked on Mars for six years. These two probes have carried out four important inspections and experiments to detect life on Mars.
The American media 065438+20071October 7th reported that some scientists published a paper saying that the Mars probe of NASA may have accidentally discovered Martian microorganisms 30 years ago, but it may have killed the discovered microorganisms by mistake in the subsequent operation because it didn't realize it.
At a recent meeting of the American Astronomical Association, Schoultze Macuch, a professor of geology from the University of Washington, pointed out in a paper that the Viking launched by NASA from 1976 to 1977 may not be able to identify the Martian microorganisms that have been found on Mars. The report pointed out that the vikings were looking for life forms similar to the earth. The characteristic of this life form is that salt water is the internal liquid of living cells. Because the surface of Mars is dry and cold, the basic unit of life forms above may be composed of a mixture of water and hydrogen peroxide, and evolved accordingly. The mixture of water and hydrogen peroxide can remain liquid at extremely low temperature, so cells will not die when frozen, and even can absorb the thin water vapor on Mars.
Schultz-Markucci said in the paper that due to technical and cognitive limitations, the Viking probe could not identify Martian microorganisms based on hydrogen peroxide in the 1970s. On the contrary, it may "drown" or "heat die" these microorganisms in unintentional operation.
Officials of the National Aeronautics and Space Administration of the United States said that this point in the report may be helpful for future Mars exploration missions, and the probe will hopefully look for possible different life forms. Scientists are excited to find that there may be liquid water flowing on Mars in recent photos. It is reported that NASA plans to conduct a new Mars exploration mission in the summer of 2008.
