NASA’s Perseverance Rover Investigates Geologically Rich Mars Terrain
NASA’s Perseverance rover is well into its second science campaign, collecting rock-core samples from features within an area long considered by scientists to be a top prospect for finding signs of ancient microbial life on Mars. The rover has collected four samples from an ancient river delta in the Red Planet’s Jezero Crater since July 7, bringing the total count of scientifically compelling rock samples to 12.

“We picked the Jezero Crater for Perseverance to explore because we thought it had the best chance of providing scientifically excellent samples – and now we know we sent the rover to the right location,” said Thomas Zurbuchen, NASA’s associate administrator for science in Washington. “These first two science campaigns have yielded an amazing diversity of samples to bring back to Earth by the Mars Sample Return campaign.”
Twenty-eight miles (45 kilometers) wide, Jezero Crater hosts a delta – an ancient fan-shaped feature that formed about 3.5 billion years ago at the convergence of a Martian river and a lake. Perseverance is currently investigating the delta’s sedimentary rocks, formed when particles of various sizes settled in the once-watery environment. During its first science campaign, the rover explored the crater’s floor, finding igneous rock, which forms deep underground from magma or during volcanic activity at the surface.
“The delta, with its diverse sedimentary rocks, contrasts beautifully with the igneous rocks – formed from crystallization of magma – discovered on the crater floor,” said Perseverance project scientist Ken Farley of Caltech in Pasadena, California. “This juxtaposition provides us with a rich understanding of the geologic history after the crater formed and a diverse sample suite. For example, we found a sandstone that carries grains and rock fragments created far from Jezero Crater – and a mudstone that includes intriguing organic compounds.”
“Wildcat Ridge” is the name given to a rock about 3 feet (1 meter) wide that likely formed billions of years ago as mud and fine sand settled in an evaporating saltwater lake. On July 20, the rover abraded some of the surface of Wildcat Ridge so it could analyze the area with the instrument called Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals, or SHERLOC.
SHERLOC’s analysis indicates the samples feature a class of organic molecules that are spatially correlated with those of sulfate minerals. Sulfate minerals found in layers of sedimentary rock can yield significant information about the aqueous environments in which they formed.
What Is Organic Matter?
Organic molecules consist of a wide variety of compounds made primarily of carbon and usually include hydrogen and oxygen atoms. They can also contain other elements, such as nitrogen, phosphorus, and sulfur. While there are chemical processes that produce these molecules that don’t require life, some of these compounds are the chemical building blocks of life. The presence of these specific molecules is considered to be a potential biosignature – a substance or structure that could be evidence of past life but may also have been produced without the presence of life.
In 2013, NASA’s Curiosity Mars rover found evidence of organic matter in rock-powder samples, and Perseverance has detected organics in Jezero Crater before. But unlike that previous discovery, this latest detection was made in an area where, in the distant past, sediment and salts were deposited into a lake under conditions in which life could potentially have existed. In its analysis of Wildcat Ridge, the SHERLOC instrument registered the most abundant organic detections on the mission to date.
“In the distant past, the sand, mud, and salts that now make up the Wildcat Ridge sample were deposited under conditions where life could potentially have thrived,” said Farley. “The fact the organic matter was found in such a sedimentary rock – known for preserving fossils of ancient life here on Earth – is important. However, as capable as our instruments aboard Perseverance are, further conclusions regarding what is contained in the Wildcat Ridge sample will have to wait until it’s returned to Earth for in-depth study as part of the agency’s Mars Sample Return campaign.”
The first step in the NASA-ESA (European Space Agency) Mars Sample Return campaign began when Perseverance cored its first rock sample in September 2021. Along with its rock-core samples, the rover has collected one atmospheric sample and two witness tubes, all of which are stored in the rover’s belly.
The geologic diversity of the samples already carried in the rover is so good that the rover team is looking into depositing select tubes near the base of the delta in about two months. After depositing the cache, the rover will continue its delta explorations.
“I’ve studied Martian habitability and geology for much of my career and know first-hand the incredible scientific value of returning a carefully collected set of Mars rocks to Earth,” said Laurie Leshin, director of NASA’s Jet Propulsion Laboratory in Southern California. “That we are weeks from deploying Perseverance’s fascinating samples and mere years from bringing them to Earth so scientists can study them in exquisite detail is truly phenomenal. We will learn so much.”
More About the Mission
A key objective for Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.
Subsequent NASA missions, in cooperation with ESA, would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
JPL, which is managed for NASA by Caltech, built and manages operations of the Perseverance rover.

Connecting Las Vegas to Southern California: Brightline West Breaks Ground on America’s First High-Speed Rail Project
Brightline West breaks ground on America’s first high-speed rail, connecting Las Vegas to Southern California. Making history!
In a groundbreaking event on April 22, 2024, Brightline West officially started the construction of America’s first true high-speed rail system. This monumental project will connect Las Vegas to Southern California, covering a distance of 218 miles. The vision behind Brightline West is to provide a transportation solution for city pairs that are too short to fly and too far to drive. This innovative rail system will run fully electric, zero-emission trains capable of reaching speeds of 200 miles per hour, making it the greenest form of transportation in the world.
The significance of Brightline West goes beyond its environmental benefits. It is a watershed project that will establish the foundation for a new industry and supply chain in high-speed rail in America. President Biden’s Bipartisan Infrastructure Bill has provided $3 billion in funding for this project, with the remaining cost of $3.5 billion being privately funded through allocated private activity bonds from the USDOT.
The groundbreaking ceremony was attended by esteemed officials and public figures, including U.S. Transportation Secretary Pete Buttigieg, Brightline Founder Wes Edens, Nevada Gov. Joe Lombardo, and several senators and representatives from California and Nevada. Over 600 people, including union representatives, project supporters, and state and local officials, were present to celebrate this historic moment.
Construction of Brightline West will take place within the median of the I-15 highway, with zero grade crossings. The rail system will include stops in Las Vegas, Victor Valley, Hesperia, and Rancho Cucamonga. The project will use an impressive amount of materials, such as 700,000 concrete rail ties, 2.2 million tons of ballast, and 63,000 tons of 100% American steel rail. Over 160 structures, including viaducts and bridges, will be built, covering more than 3.4 million square feet with retaining walls. The entire project will be fully Buy America Compliant.
Brightline West aims to revolutionize travel between Southern California and Las Vegas. The rail system will reduce travel time to just two hours, nearly half of the time it takes to drive. The Las Vegas Station will be conveniently located near the iconic Las Vegas Strip, providing easy access to the Harry Reid International Airport, the Las Vegas Convention Center, and the Raiders’ Allegiant Stadium. The other stations, including Victor Valley, Rancho Cucamonga, and Hesperia, will offer seamless connectivity to various locations in Los Angeles, Orange, San Bernardino, and Riverside Counties.
The economic and environmental benefits of Brightline West are significant. The $12 billion investment in infrastructure will generate over $10 billion in economic impact for Nevada and California and create more than 35,000 jobs, including 10,000 direct union construction roles and 1,000 permanent operations and maintenance positions. The rail system will contribute to the reduction of greenhouse gas emissions by over 400,000 tons of CO2 annually, equivalent to reducing vehicle miles traveled by more than 700 million each year and eliminating the need for 16,000 short-haul flights. Additionally, Brightline West will construct three wildlife overpasses to ensure the safe passage of native species, particularly the bighorn sheep.
The success of Brightline West builds upon Brightline’s existing rail system in Florida, which connects Miami to Orlando. With plans to expand further to Tampa, the Space Coast, and the Treasure Coast, Brightline is spearheading the development of high-speed rail in the United States.
The groundbreaking of Brightline West is a historic step towards transforming transportation in America. This ambitious project brings us closer to fulfilling the dream of high-speed rail and sets an example for future city pairs in the country.
