Liquid Water on Mars

“Twelve orbits a day provide the Mars Global Surveyor MOC wide angle cameras a global “snapshot” of weather patterns across the planet. Here, bluish-white water ice clouds hang above the Tharsis volcanoes. This computer generated image was created by wrapping the global map found at PIA02066 onto a sphere.”–Via NASA

“2015” will appear on every mayor textbook as a significant year for scientific achievement. On October 5th, 2015 it was announced that there is unambiguous proof that brine (water with a lot of salt) flows on the martian surface during its warm months:

File:Dark Flows in Newton Crater Extending During Summer (animated).gif

From the press conference that NASA gave a few days ago:

The dark, narrow streaks flowing downhill on Mars at sites such as this portion of Horowitz Crater are inferred to be formed by seasonal flow of water on modern-day Mars. The streaks are roughly the length of a football field.

The imaging and topographical information in this processed view come from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.

These dark features on the slopes are called “recurring slope lineae” or RSL. Planetary scientists using observations with the Compact Reconnaissance Imaging Spectrometer on the same orbiter detected hydrated salts on these slopes at Horowitz Crater, corroborating the hypothesis that the streaks are formed by briny liquid water.

What does this mean for life? Does this discovery boosts expectations for martian life? Should we go up there? If so, what measures do we have to take once we reach these salty slopes?

    • Scientists are definitely trying to find a way to make life sustainable on the Martian surface. But I believe that before we go tho Mars, we have to think a lot about what our own microbes might do the probable life on Mars.

  1. It means that Mars is the closest thing to Earth and who knows, maybe one day it will be considered one. Except that it wouldn’t exactly be the same given the fact that it’s probably really cold and the water can be useful for us as well. There would have to be many changes in order for humans to actually be able to live there, but it could be possible.

    • There are a lot of moral implications when it comes to science, and space exploration is not an exception. This discovery has been somewhat controversial, mainly because not all scientists agree that we should go there? What reasons might these scientists have for saying that going to Mars is not a good idea? I suggest yo do research on the web to look for the answer.

    • Moral is always a main setback in any decision. As our Mr. Adrover mentioned, there is no exception in space exploration. One conflict that can come to mind is as simple as the temperature fluctuations in Mars. Just because we have found water does not mean the cost of creating habitats that can withstand the tremendous changes in temperature due to Mars’ primitive atmosphere has decreased. Not only that, but it does not guarantee that the mortality rate or failure of the mission will lessen. It all becomes a matter of scientific ethics that must be investigated thoroughly before any decisions are made.

  10. In my book, this classifies as the scientific discovery of the century as it is known that major scientific discoveries do not happen so often, as mentioned by our Mr. Adrover. However, I fear that despite its significance in the scientific community, it may not be too significant in the practical community.

    Let me make myself clear. We now know that Mars does contain brine yet it has been found to emerge only during Mars’ warm seasons. This means that this source of water will not be present throughout the entire Martian year, and life will not thrive there unless it finds a way to endure the long periods of drought. Even extremophiles might not be able to endure the harsh conditions Mars has to offer, from constant changes in temperature to scarce sources of the precious liquid most of us take for granted.

    Now, going a bit further into analysis, if we decide to commence populating Mars, the task will prove to be extremely difficult and unlikely to last because we do not have the necessary resources to keep a constant supply of water present, and a large one while at it. Our materials would largely depend on the current water found on Mars, just as we depend on our oceans, lakes, and rivers for our water supply. Until we can find a way to synthesize consumable water, either from water vapor in the atmosphere or completely from scratch in the laboratory, we will not be able to make life on Mars explode with diversity.

    Nevertheless, this setback does not take away any significance to the discovery nor any doubt that it is an advancement in our scientific society. As we continue to develop new ways of improving life on Earth, we plant the seeds of knowledge that will grow to become the plants and trees on Mars and wherever it is possible in our vast universe.

  11. As Stephen Hawking says, Mr. Adrober also said it, humans should evacuate Earth. As we can see Earth is passing through a difficult moment with the extreme levels of pollution. And some scientists have said that if we keep at this pace, Earth will come to an end. With this discovery of liquid water on Mars, it can be an option for the future. But still many tests have to be done and for now it is not even worth it because there are signs that the water is not present all the time.

    So yes it has been a huge discovery but there are too many questions and doubts left.

  12. Water is very important to all living beings. It’s great news because if in the future we can’t live on Earth because of many reasons, we can save the human race. But, water is not the only thing that we need to be alive. Scientists are now wondering if Mars has other elements like carbon, nitrogen, etc. (sciencelearn.org.n2/Contexts/Just-Elemental/Science-Ideas) Another factor that Scientists are figuring out is the amount of radiation. In February 17 in 2004 NASA has said that it’s very dangerous the space radiation could affect astronauts on Mars. Frank Cucinotta of NASA’s Space Radiation Health Project, explains that a long trip to Mars is filled with protons from solar flares, gamma rays from newborn black holes, and cosmic rays from exploding stars. He said that NASA knows how much radiation is out there, and they are not sure how the human body is ready to react the outside world. http://science.nasa.gov/news/science-at-nasa/2004/17feb-radiation

  14. I think that even though we can now go to Mars after water has been discovered it wouldn’t be an easy process moving to another planet. First, studies have shown that the journey to Mars could be life threatening because of gamma rays and the amount of radiation that if found. Second, not all humans will be able to travel, especially the low class, because we as a species always give credit to the high class first and third if the journey goes as planned and we build settlements on Mars people will always want more than other and conflicts will arise just like right now on Earth. Saying that we could live in Earth is possible but we as human beigns will make the same mistakes and destroy our new home and go through the same process again.

  15. It is a great achievement to find water on Mars, but water is not the only compound or element we need for life. We need sulfur, phosphorus, oxygen, nitrogen, carbon, and hydrogen (SPONCH). I also think that calcium (Ca) and iron (Fe) are important because we need calcium for our teeth and bones and iron because it is important when it comes to synthesizing hemoglobin. http://www.learner.org/courses/essential/life/session8/closer3.html
    I think that if these elements are found in Mars, it would take many years for us, humans, to live in Mars. NASA has made and exploration strategy to find past and present life on Mars called “Seek Signs of Life”. This strategy will help us know if life ever existed on Mars millions of years ago and if it is possible to have life now a days or if it is possible for humans to inhabit Mars in the future.

Water is very important for life, but without the other elements we could never live in Mars.

  18. Water as we know is an essential component for all living things. The discovery of water on the planet of Mars is a very important and significant event for science and its evolution. These findings present a new perspective of life on Mars meaning there could be actual life on this planet. This definitely increases scientists’ expectations to find either present life or past life on Mars. Although water is very important, other certain elements are needed for an organism to grow and develop correctly (SPONCH). I believe that scientists should go and explore Mars and when they reach the salty slopes get some testings to see if the water is highly acidic or not, if it has minerals and or if it has organisms living on it which would definitely point out that there is life on the planet. Who knows maybe in the future humans can be able to live on Mars.

  19. Humans have a great ability for self-destruction. Science has proven this and why we, an intelligent species, are nasty and hurtful. Our species will lead itself to its own destruction. When Albert Einstein says “I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones” he agrees to our self-destruction. I state this for the sake of our survival the migration of Earth to Mars might be necessary.

    It might be imperative that scientists find more information and processes that will aid this future migration to become a near reality and learning that Mars has salt water is great start. Scientists are still searching for evidence that proves that complicated life on Mars does exist. Even though they know not if complicated life on Mars exist, they have performed experiments to see if plants can grow on Martian soil. In one experiment, scientists copy Martian soil and grow plants on it. The results of this experiment were astonishing but not completely accurate because they lack some variables like Mars’ gravity and the amount of sunlight the plants receive on Mars.

  20. Although this is definitely one of the greatest achievements of modern human history, I honestly and respectfully do not believe that it came in the adequate time. This assumption comes from the basis that this discovery is extremely similar to that done when humans reached the moon. Although reaching the moon certainly was another great milestone, by most it was treated like any other discovery done here on Earth. Sadly people only thought of money when they heard that going to the moon was possible. Without the knowledge that we later got from moon exploration, people were already trying to find a way to create a monopoly out of it. It is extremely sad that only few gave it the educational importance that it really had. Treaties were made to protect it, treaties similar to those done in the XV and XVI centuries when discovering the new world. We all know that these treaties will eventually be violated. People rapidly thought of it as a business, and we could all agree that creating a business out of it would create huge conflicts.

    When I think of this I only fear for the future of Mars. I believe that this planet has great educational potential and can lead to better understanding of the world, but if treated like the moon it could become worthless in the next couple of centuries. I also hope that humanity notices that not everything is meant to become a business. Along with many other things business create competition, this is exactly the opposite of what we need for this project. We need collaboration.

  21. The discovery of water on Mars is a huge step for science and mankind. This discovery can lead humans to think that life can be supported in Mars. This can be assumed because water is very important for living organisms; two of its main functions is in photosynthesis which helps in the making of glucose and in cellular respiration in which glucose is broken down for its stored energy, as learned recently in class. But scientists also need to look at other factors such as the planet’s atmosphere, the temperatures, and the known and maybe unknown elements that can be found, to be certain that life can happen and be completely supported in this planet. And if the proper conditions are discovered and humans invent the technology needed, I think humans should go to Mars. Once humans reach there, they should experiment and discover as much as they can. Who knows, maybe Mars may end up as a second home for humans and certainly huge place for new scientific discoveries. In fact, there are already people signed up for a trip to Mars to establish a human settlement and it is being called Mars One.

  22. On October 5, 2015, a huge discovery for the scientific world was made, water was found on Mars. This means that there is a bigger possibility to believe in extraterrestrial life in another planet, but we won’t be sure of it until we explore. In my opinion, I think we should travel to Mars to undergo investigations and inquiries, but that would take a long time since no human being has ever been to Mars. Due to the amount of radiation found in space and the inability to know how humans will react to it. As we all know, for human life to exist we need more than just water, we need to look for other elements such as the SPONCH elements. We should look in different areas of the environment to see what we may find. People should go to Mars because if we don’t, we will always wonder what it would have been like. Nonetheless, saying it is easier than doing it. In order to go to Mars we have to look at all the consequences and hardships that may occur because of radiation’s unpredictable reaction. Having this in mind, the people who attempt to go should know that it won’t be a simple or easy journey, in the contrary, it will be worth it if we finally reach and step foot on Mars.

Water on Mars is a great discovery but the possibility of us actually living in Mars right now is basically non-existent as we don’t know if the rest of the SPONCH elements are available in Mars and because of it’s thin atmosphere we would get less air and more radiation from space. However that doesn’t rule out the possibility that organisms who don’t require SPONCH elements to survive live or used to live there and though it sounds far-fetched there is actually life on Mars.

    “We know there’s life on Mars already because we sent it there,” John Grunsfeld, the associate administrator of the agency’s Science Mission Directorate, said during a press conference on Monday. It is a Faustian condition of space exploration that we cannot search for life on alien planets without bringing along very small amounts of very small Earth life.

    Since I was curious to know if I was right, I searched on Google and found this article about it. It says that in the John Klein area there is evidence that it had many of the elements needed for life including sulfur, phosphorus, oxygen, nitrogen, carbon, and hydrogen. This means that there is a possibility that there may have been life on Mars. Know I am probably going to be very attentive to any news from NASA on Mars to see if this hypothesis could have any truth to it.

  44. Water is very important for life. The recent discovery of liquid water on Mars is very significant for science. This is one of the greatest achievements of human history. From this discovery it can lead it can lead to humans to think that life in Mars is possible. Liquid water is very essential for life but other elements like the SPONCH elements are also important. Scientists will keep investigating if life is present on Mars.

  45. Water is one of the vital necessities needed for humans to survive. Without it, there is no chance of survival. After NASA showed evidence of liquid water flowing on Mars, scientists have considered the possibility of humans having a chance to visit or live on Mars. This discovery opens up doors for many different opportunities and discoveries waiting to be made. I believe that with this evidence found we can explore more in regards of Mars and human’s chance to be able to go to Mars.

  46. “Mars One” is an organization based in the Netherlands that has proposed to land the first humans on Mars and establish a permanent human colony there by 2026. With this new discovery, there is no doubt that this mission was supported, and that there may be more planets out there (exoplanets, specifically) that can host human life.

  47. The discovery of water on another planet that isn’t Earth is by far one of the most astonishing discoveries that science has recently made. This is the spark needed in order to confirm that eventually life could evolve and that possibly one day us humans could inhabit the planet. Nevertheless, in order for life to flourish, much more things besides water (sulfur, phosphorus, nitrogen and carbon) are needed, but it is a good start. Knowing how fast science advances, it is only a matter of time before we find life on Mars! https://www.nasa.gov/press-release/nasa-confirms-evidence-that-liquid-water-flows-on-today-s-mars

  48. With the discovery of liquid water on Mars can set us one step closer to finding life outside of Earth. NASA has launched many rovers to study the martian surface and it has found some remarkable things. Scientist are now figuring out a way to send humans to Mars and study the things rovers can not. Space agencies like for example, NASA, Space X, and ESA are trying to make this happen, probably causing a new Space Race. Although there is water, there are more things needed to sustain life. However, in the future, Mars could be terraformed making it possible for humans to live normally on the planet.
