The test results show that the sample is similar to Earth's organic-rich sedimentary rock and contains a variety of molecules including thiophene, benzene, toluene and small carbon chains (such as propane or butene). Although this discovery does not mean that Curiosity has found evidence of ancient life on Mars, researchers say it is a promising step. In the future Mars mission, scientists plan to dig deeper into the Martian soil and find evidence that Mars is suitable for the existence of life in ancient times.
The Curiosity Rover drilled on a rocky surface called “Buckskin” in Sharp Mountain, where it found evidence of possible microbial life on Mars.
The researchers hope that humans will be sent to Mars by 2040, but the realization of this plan depends on many factors. If you want to get a person on Mars, you first need to be able to send about 10 tons of material to the surface of Mars. At present, NASA has been able to land a detector weighing about one ton.
NASA also needs to develop technologies that will enable spacecraft to launch on Mars and return to Earth. The Mars 2020 rover is likely to achieve this goal. "Sometime in the next decade, we plan to launch spacecraft from the surface of Mars and return to Earth," Green said.
The greatest obstacle to the future survival of human beings on Mars may be to build a complete infrastructure. Green said: “People who are willing to go there are true pioneers.” Similar to the scenes in the movie “The Martian”, humans need to grow crops and establish stable foods in order to live on Mars. source.
"Organic substances may come from life, but the presence of organic matter is not evidence of life, because organic matter may also come from non-living processes," she added. "We have found that organic matter in rocks is exposed on very harsh surfaces, often resulting in organic matter. Decomposition. Finding organic matter in this harsh environment means that we may find better-preserved organics elsewhere, especially those that have not been exposed to much radiation."
Due to the successful completion of the mission, Curiosity's working hours have been extended indefinitely and it has been running for more than 2,000 days.
Curiosity Rover's Achievement
The Curiosity Mars Rover initially launched on November 26, 2011 at Cape Canaveral, Florida Air Force Base. After a 560-million-kilometer journey, the rover, worth about $2.5 billion, finally landed on Mars, only 2.4 kilometers from the marked landing site.
Since the successful landing on August 6, 2012, the Curiosity Rover has traveled about 18 kilometers. It was launched by the spacecraft of the Mars Science Laboratory (MSL), which weighed 23% of the total spacecraft weight.
The Curiosity has a total weight of 899 kg. The scientific equipment loaded is 80 kg and is powered by a helium fuel source. It has a length of 2.9 meters, a width of 2.7 meters and a height of 2.2 meters.
In the initial plan, Curiosity will conduct two-year exploration missions to collect information on whether Mars can support life, including the existence of liquid water, and to study the climate and geology of Mars. Due to the successful completion of the mission, Curiosity's working hours have been extended indefinitely and it has been running for more than 2,000 days.
The Curiosity is loaded with a variety of scientific instruments, including two main cameras mounted on the mast, one fixed focus for the middle focal length, and one fixed focus for telephoto, capable of shooting high-resolution true-color pictures andvideo. Up to now, this detector, which is almost as big as a car, has found an ancient riverbed where liquid water once flowed. It also discovered a place called Yellowknife Bay, which was part of a lake billions of years ago, and there may be microbial life in this ancient lake.
