NASA may be preparing to deliver some monumental news about Mars after surprisingly calling for a rare news conference on Wednesday.
Officials with the space agency said they plan to discuss a ‘new finding’ by the Perseverance rover, which has been on the Red Planet since 2021.
The discovery involves a rock called ‘Sapphire Canyon,’ collected by the rover in July 2024 from an ancient river system in a Martian area called Neretva Vallis.
Scientists are excited because this rock might contain ‘biosignatures,’ which are chemical clues that could hint at ancient microbial life on Mars.
Neretva Vallis is part of Jezero Crater, a place where a river existed billions of years ago, making it a prime spot to search for signs of Martian life.
Astute observers on social media have already noted that NASA rarely holds media events for their discoveries, so this announcement could be marking a major scientific finding that captures the world’s attention.
In the past, NASA used similar events to share discoveries like finding organic molecules on Mars in 2018 and detecting a gas called phosphine on Venus in 2020, both of which sparked discussions about possible life forms on these worlds.
While NASA has a history of being extremely cautious with saying they’ve found signs of life on other planets, the announcement scheduled for September 10 at 11am ET has already created a buzz among astronomy fans.

Many on social media have speculated that NASA’s announcement could be connected to a study presented earlier this year at the 56th Lunar and Planetary Science Conference in Texas.
The study, led by scientist Joel Hurowitz, described how the Perseverance rover found unusual spots and seed-like shapes in ancient Martian rocks that might point to the existence of tiny life forms in the distant past.
Hurowitz is also scheduled to be one of the scientists present during the NASA event on Wednesday.
These features, nicknamed ‘poppy seeds’ and ‘leopard spots,’ were spotted in mud-like rocks in Neretva Vallis, which the rover has been exploring since landing on Mars.
The rover’s tools detected chemicals like iron and phosphorus in these spots, which on Earth can form when tiny microbes break down organic material, leading some to call this possible proof of ancient Martian life.
Social media posts, especially from space news accounts like NASA Watch and Astrobiology, have also highlighted the study’s title, ‘The Detection of a Potential Biosignature by the Perseverance Rover on Mars,’ as matching the kind of big reveal NASA might be ready to announce.
The Wednesday event could mean the space agency is ready to share more details or new tests on the ‘Sapphire Canyon’ sample that have taken place since the March conference.
New NASA Administrator Sean Duffy, NASA’s Senior Scientist for Mars Exploration Lindsay Hays, and Perseverance Project Scientist Katie Stack Morgan are also among the space officials scheduled to be in attendance.

NASA called a press conference in June 2018 to share exciting results from the Curiosity rover, which has been exploring Mars since landing in 2012, mainly to discuss new clues about the planet’s past ability to support life.
The rover had analyzed ancient rocks in Gale Crater, where a lake once existed billions of years ago.
It was revealed that complex organic molecules, called carbon-based building blocks that are essential for life, had been preserved in 3.5-billion-year-old bedrock.
In September 2020, NASA took part in a major international announcement that revealed observations from ground-based telescopes focused on a surprising gas detected in Venus’s atmosphere.
Scientists had found the presence of phosphine in Venus’s upper clouds, about 30 to 60 miles above the surface.
The discovery raised serious questions about unknown chemical (and possibly biological) processes on the planet, since no obvious non-living source could explain the gas being there.
This was groundbreaking, as it was the first reported detection of phosphine on a rocky planet like Venus, sparking global debate about whether multiple planets in our solar system once harbored life.
However, NASA has yet to definitively confirm that life has existed on Mars or any other planet in our galaxy.
