NASA's Curiosity rover has found some interesting organic compounds on the Red Planet that could be signs of ancient Mars life, but it will take a lot more work to test that hypothesis.Jan 18, 2022
Has Curiosity found anything on Mars?
The rover has found new evidence for ancient hot magma and abundant water. It has also discovered ancient organic molecules, the sorts of molecules found in all living things, still preserved in rocks and dust.
How will Curiosity find evidence of life on Mars?
In the search for evidence of past life on Mars, the Curiosity team has subjected ancient deposits of waterborne sediments exposed by eons of weathering to a battery of tests that include carbon isotope analysis. Two stable isotopes of carbon occur in nature: carbon-12 and carbon-13.
Is Curiosity still working on Mars?
The rover is still operational, and as of April 5, 2022, Curiosity has been active on Mars for 3435 sols (3529 total days; 9 years, 242 days) since its landing (see current status)….Curiosity (rover)

What has Curiosity left behind on Mars?
Curiosity has found that ancient Mars had enough carbon in the rocks and soils to serve as raw material for life, if it ever existed, says Vasavada. Curiosity has found that the lakebed rocks in Gale crater had a diversity of organic molecules, he says. Most are simple, only a few carbon atoms in length.
Was there life Venus?
To date, no definitive proof has been found of past or present life there. In the early 1960s, studies conducted via spacecraft demonstrated that the Venusian environment is extreme compared to Earth's.
Is there organic life on Mars?
Organic compounds – those containing carbon atoms – found all over Mars were produced by water interacting with volcanic rocks, according to the analysis of a Martian meteorite. These compounds are important to life, and figuring out how they are produced could help us understand Mars life if we ever find it.
What did Mars look like billions of years ago?
Four billion years ago, Mars was a completely different world. It had blue skies, fluffy clouds, and flowing water. Today, the planet is cold and dry with no signs of life. The transition from an ancient habitable world to a cold desert is depicted in a new video released by NASA's Conceptual Image Lab.
Is Mars habitable?
Ongoing findings from rovers, landers and orbiters suggest the planet was habitable – suitable for life – in the past. Of course, habitable doesn't mean inhabited.
Can humans live on Mars?
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.
