Small rock patterns on Mars might have massive implications for humanity. Here’s what to learn about life on Mars.
New findings trace to potential life on Mars
NASA’s Mars rover has discovered what seems to be its strongest proof but for historical life on the planet.

The seek for life on Mars dates again about 5 many years, and a Sept. 10 announcement marks maybe probably the most dramatic development but.
The information: NASA’s Perseverance rover had discovered potential indicators of historical microbial life on Mars.
The discovery represents “the closest we have ever come to discovering life on Mars,” NASA appearing Administrator Sean Duffy mentioned in a statement saying the discover.
“The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars,” Duffy continued.
And yet, the discovery represents a confounding moment.
On one hand, scientists have touted the news as a landmark advancement toward answering an ancient question: Are we alone in the universe?
On the other, the finding doesn’t prove the existence of ancient life – and experts warn it will take more work to confirm these findings.
“If there was life on Mars, it might be extraordinarily thrilling for science,” said Lindsay E. Hays, senior scientist for Mars exploration at NASA, via e-mail. “Not solely wouldn’t it reply one in all humanity’s oldest questions on whether or not we’re alone, it might even have implications for the way life originates and evolves in addition to spreads all through planetary methods like our photo voltaic system.”
What was announced about Mars?
A sample of rock that Perseverance collected in 2024 from an ancient dry riverbed in the Jezero Crater could preserve evidence of ancient life, NASA announced at a news conference. The reddish rock formed billions of years ago from sediment on the bottom of a lake in Jezero Crater, which represents what researchers believe is one of the best places to find evidence that Earth’s planetary neighbor was ever home to life.
What do scientists think about the ‘life on Mars’ discovery?
While many in the science community are somewhat familiar with these features from last year’s announcement, there is significantly more excitement now, with the publication of the paper that solidifies them as potential biosignatures. “This is the stage the place the science group can actually dig into the findings, and themselves have interaction with them as a part of the scientific course of,” Hays mentioned.
What happens now?
The next few years of science will focus on the specific results from this paper, which she expects will include studies trying to identify alternative ways to produce the features measured here. In the longer term, the best way to properly confirm these findings would be to return samples for analysis in terrestrial laboratories.
What if there really was life on Mars?
Hays said the confirmation of ancient life on Mars would kick off a series of new questions, things like:
- Does life originate any time and place that conditions are suitable?
- If life originated either on Mars or Earth, could it have spread to the other planets through normal processes?
- Is life still present somewhere on Mars today?
The floor of Mars is just not thought of liveable in the present day, Hays mentioned, as it’s each chilly and really, very dry. “Since the Viking landers, NASA’s Mars exploration has been targeted on trying to find water, searching for previous liveable environments, and searching for indicators of previous life, however haven’t had aims of searching for fashionable life on Mars.” (The Viking landers investigated The Red Planet about 50 years ago.)
“As we discover additional into the photo voltaic system, and deeper into the subsurface of planets, we hope to be taught extra together with what the potential for all times could possibly be in numerous environments,” she mentioned.
