Reading text

A new study published in the journal Science shows definitive evidence of organic matter on the surface of Mars. The data was collected by NASA's nuclear-powered rover Curiosity. It confirms earlier findings that the Red Planet once contained carbon-based compounds. These compounds – also called organic molecules – are essential ingredients for life as scientists understand it.

The organic molecules were found in Mars's Gale Crater, a large area that may have been a watery lake over three billion years ago. The rover encountered traces of the molecule in rocks extracted from the area. The rocks also contain sulfur, which scientists speculate helped preserve the organics even when the rocks were exposed to the harsh radiation on the surface of the planet.
Scientists are quick to state that the presence of these organic molecules is not sufficient evidence for ancient life on Mars, as the molecules could have been formed by non-living processes. But it's still one of the most astonishing discoveries, which could lead to future revelations. Especially when one considers the other startling find that Curiosity uncovered around five years ago.
The rover analyses the air around it periodically, and in 2014 it found the air contained another of the most basic organic molecules and a key ingredient of natural gas: methane. One of the characteristics of methane is that it only survives a few hundred years. This means that something, somewhere on Mars, is replenishing the supply. According to NASA, Mars emits thousands of tons of methane at a time. The level of methane rises and falls at seasonal intervals in the year, almost as if the planet is breathing it.
NASA suspects the methane comes from deep under the surface of the planet. The variations in temperature on the surface of Mars cause the molecule to flow upwards at higher or lower levels. For example, in the Martian winter the gas could get trapped in underground icy crystals. These crystals, called clathrates, melt in the summer and release the gas. However, the source of the methane is still a complete mystery.
The world of astrobiology considers both of these studies as historical milestones. According to this information, Mars is not a dead planet. On the contrary, it is quite active and may be changing and becoming more habitable.
Of course, this means further research is necessary. Scientists say they need to send new equipment to Mars, equipment that can measure the air and soil with more precision. There are already missions underway. The European Space Agency's ExoMars ship lands in 2020 and will be able to drill into the ground on Mars to analyse what it finds. Additionally, NASA is sending another Mars Rover in the same year to collect samples of Martian soil and return them to Earth.
The possibility of life on Mars has fascinated humans for generations. It has been the subject of endless science-fiction novels and films. Are we alone in the universe or have there been other life forms within our Solar System? If the current missions to the Red Planet continue, it looks as if we may discover the answer very soon.

It could be, but I have an important question too: Will humans take care of their own planet one day? Man, I live in El Salvador and right now it is raining. We have a lot of problems in different places due to contamination.

If you could live on Mars if it is adapted to the requirements for humans to live, you could make oxygen domes, but it would also be water as it is very essential, thinking about it would serve more to obtain resources.

I think this option is possible but in the future because all of we know that is not that easy like go in a rocket and make life, and we need make equipment for this planet

I think we will live in mars, maybe not tomorrow maybe not in like 5 years, because all of we know that is not that easy like go in a rocket and make life, it's difficult but is possible there is no evidence that in the past maybe someone lived there but obviously is possible and we are going to make it.

I don’t think people will be able to live in Mars in the short term, but maybe some day If the technology reach certain point of development that allow people to colonize other planets and the earth turns uninhabitable, then it could be possible to study the possibility to stablish colonies in other planets like Mars.

Thanks for the lesson.
Great site!

I am not going to share my opinion because of my lack of knowledge on this subject but I can tell you about the new NASA program link to Mars.
Indeed, the Artemis program has to send astronauts to the Moon in 2025. But this mission is far from a basic expedition like we could have seen it 50 years ago. In fact, NASA's true goal is to test human beings for a long period on another planet/satellite and be ready for Mars!
History is in the making, but not yet.

It is still uncertain if humans will be able to live on Mars but I think that this possibility is very close, human technology has been very close to Mars, so it could be a possibility that humans live on Mars, but little by little

I think that we will never live on Mars.
