If you have been following our Mars Exploration Newsyou know that scientists are waiting for the day when they can exclaim “Eureka! There’s life on this dead, floating space rock!” Luckily, a 2,260-pound robotic geologist living in Jezero Crater on Mars named Perseverance (or “Percy” for short) is helping them get a little closer to that goal.
One of Perseverance’s goals is to help humanity search for ancient life on Mars. Unlike its previous rover brethren, Percy’s superpower is its ability to store rock samples that geologists deem interesting enough to be cached for possible return to Earth. This is very similar to how Wall-E collects trash with its robotic belly; however, Percy doesn’t crush and compress the material inside (which would cause some Very angry scientists, we imagine).
Captured rocks can be Future Missionand then transported back to Earth for detailed study. Perseverance has a A full set of high-tech equipment The ship is equipped with sensors and tools to conduct analytical surveys of the rocks and provide decision-making information for sample collection.
Can you imagine what sample collection would be like? Check out this animation And get excited about it with us.
When asked about the importance of the Mars mission, Emeritus Scientist Dr. Ken Herkenhoff emphasized the importance of sample return in the minds of scientists. Long has always been a goal of the planetary science community,” he mused. Experts on the subjectDr. Herkenhoff has worked in planetary science for more than 25 years and has been involved in too many critical missions over the years to mention, most recently being part of the team that selected which Percy samples would be preserved for return to Earth.
Who is Percy? Search What exactly are the signs of life in these rocks? How do scientists like Dr. Herkenhoff decide where to look for samples? Potential biosignatures, or markers of life like specific ions, elements and isotopes, are the most critical information scientists can glean from the rocks Percy observed. While we won’t ramble on about the chemistry involved, just know that if a biosignature is found on another world as well as on Earth, it’s a big indicator that life as we know it may have once existed (or still exists) on that world. That’s why the presence of water on other worlds is so important to planetary scientists — it suggests that perhaps rivers, lakeOr there could be microbial life in the oceans of these planets, as is the case today on Earth.
Jezero Crater, which Perseverance was sent to explore, is an area that could be rich in biosignatures because it is thought to have been a river delta in its heyday.3.5 billion years ago), which flows into the now-dry Lake Jezero.
Then, in May 2023, Percy investigated a rock called “Ozul Falls” and found something that was definitely worth celebrating. According to NASA, Percy’s analysis of the rock showed that it was rich in biosignature phosphates.
The image below shows Ozel Falls and a list of materials identified within it, including large, millimeter-scale areas rich in phosphates. PIXL data is overlaid on the image. The colored squares show where PIXL’s X-ray beam scanned different areas of the rock surface. Click here to see NASA’s full findings.
While this may not be as exciting to non-scientists as Percy meeting little green men, rest assured, this is a big deal. Phosphorus is an element that is considered a building block for life as we know it. It is found in the DNA and cell membranes of all life on Earth and is a way for organisms to store and transfer energy.
USGS scientists such as Dr. Ryan Anderson, Dr. Paul Giessler and Dr. Lauren Edgar, who are currently part of the team helping Percy with its geological exploration, believe this discovery is the first of many “Eureka!” moments to be celebrated during the mission.
Know that we can use high resolutionobtain sample analysis supporting evidence of life on Mars, and obtain Helicopters Flying through the planet’s thin atmosphere, we’ve already been impressed by what has been accomplished on Mars. Still, we’re patiently waiting to see what we’ll discover when humans finally make the journey to the fourth planet in our solar system, and to prepare for the upcoming Artemis Mission Landing on the moon will open up humanity’s space exploration deeper into the solar system.
