Humans are "absolutely" able to land on Mars in their lifetimes.

Beijing time on June 20, according to foreign media reports, not long ago, scientists on Mars found a "structural basis of life."
, a nasa chief scientist said that humans are now "absolutely" able to land on Mars in their lifetimes.
two separate studies of data collected by the Mars rover over the past two years, scientists have discovered an ancient lake containing a wealth of organic matter and analyzed the sources of methane in the Martian atmosphere.
these breakthrough results will help scientists find microbial life on Mars and deepen our understanding of seasonal changes on Mars.
NASA scientist Jim Green said in an interview that the future of humans is "absolutely" possible to live on Mars.
Curiosity rover extracted and heated samples at two sampling sites in the Gale crater, Mojave and Confidence Hills, which date back about 3 billion years.
tests showed that the samples were similar to sedimentary rocks rich in organic matter on Earth and contained a variety of molecules, including pyridine, benzene, toluene and small carbon chains such as propane or butene.
while the discovery does not mean curiosity has found evidence of ancient life on Mars, the researchers say it is a promising step.
In future missions to Mars, scientists plan to dig deeper into martian soil and find evidence of the suitability of life in ancient Times.
researchers hope to send humans to Mars by 2040, the plan depends on a number of factors.
to get a man to Mars, it would first need to be able to deliver about 10 tons of supplies to the surface of Mars.
now, NASA has been able to land a probe weighing about a ton.
NASA also needs to develop technology that will allow spacecraft to launch and return to Earth on Mars.
Mars 2020 rover is likely to achieve this goal. "
At some point in the next decade, we plan to launch a spacecraft from the surface of Mars and return to Earth," Green said.
the biggest obstacle to future human survival on Mars may be building a complete infrastructure. "People who are willing to go there are real pioneers,"
Green said.
" is similar to the scene in the film The Martian, where humans need to grow crops and establish a stable food source if they are to live on Mars.
"The new findings reinforce our conclusion that organic matter exists in ancient sediments on Mars and tells us how organic molecules are preserved in rocks," said study lead author Jennifer Egenbrod, a astrobiologist. "The detection of rocks containing organic matter from The Ancient Habitable Environment of Mars is a good indicator of future life on Mars," said
Eigenbrode).
"Organic matter 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.
finding organic matter in this harsh environment means that we may find better-preserved organic sourases elsewhere, especially where they are not exposed to large amounts of radiation.
Curiosity Mars rover was originally launched from Cape Canaveral, Florida, U.S. Air Force Base on November 26, 2011.
after a 560 million-kilometer journey, the $2.5 billion rover finally landed on Mars, just 2.4 kilometers from the marked landing site.
since landing successfully on August 6, 2012, the Curiosity rover has traveled about 18 kilometers.
it was launched through the Mars Science Laboratory (MSL) spacecraft, which weighs 23 percent of the spacecraft's total weight.
Curiosity weighs 899 kg and is loaded with 80 kg of scientific equipment powered by a plutonium fuel source.
it is 2.9 meters long, 2.7 meters wide and 2.2 meters high.
original lying, Curiosity will conduct a two-year exploration mission to gather information on whether Mars can support life, including the presence of liquid water, and study the climate and geology of the country.
Curiosity's working life has been extended indefinitely and has been running for more than 2,000 days because of the success of the mission.
Curiosity is loaded with a variety of scientific instruments, including two main cameras on the loading mast, one for the mid-focus segment, and one for the distant focus, and can take high-definition true color pictures and videos.
so far, the probe, which is about the size of a car, has found an ancient riverbed where liquid water once flowed.
it also found a place called Yellowknife Bay, which was part of a lake that was part of a lake that may have had microbial life in the ancient lake billions of years ago.
