Perseverance Rover Set to Nibble on “Krokodillen” Rock Formation on Mars
NASA’s Perseverance rover is gearing up for its next scientific task: taking a sample from a fascinating rock formation nicknamed “Krokodillen” on Mars. This upcoming sampling marks an exciting continuation of the rover’s mission to collect promising rocks that could hold clues to past Martian life.
What is “Krokodillen”?
The “Krokodillen” formation isn’t a single rock, but a distinctive area on the Martian surface characterized by its dark-toned and fractured rocks. The name, which means “Crocodiles” in Afrikaans (a language spoken in South Africa and Namibia), was chosen because the rocks reminded the science team of crocodile scales or teeth due to their texture and arrangement.
Why is “Krokodillen” interesting?
Scientists believe “Krokodillen” could provide valuable insights into Mars’s past for several reasons:
- Composition: The dark tones suggest a potentially different mineral composition than other rocks Perseverance has sampled in the Jezero Crater. This variance is crucial for understanding the diversity of the crater’s geological history.
- Fractures: The fractures in the rocks might indicate that they have been exposed to water at some point. Water is essential for life as we know it, so finding evidence of its interaction with these rocks would be highly significant.
- Potential for Preservation: The structure of the rocks could have created niches where organic molecules, the building blocks of life, might have been preserved over billions of years.
How will Perseverance “take a bite” out of “Krokodillen”?
Perseverance is equipped with a sophisticated drilling system that allows it to extract core samples from Martian rocks. The process involves:
- Selecting a Target: The rover’s cameras and instruments are used to carefully examine the rocks and choose the most promising spot for sampling.
- Abrading the Surface: Before drilling, Perseverance uses a rock abrasion tool (RAT) to grind away the outer layer of the rock. This exposes a fresh, uncontaminated surface for analysis.
- Drilling a Core: The rover uses a drill bit to extract a cylindrical core sample, about the size of a piece of chalk.
- Sealing the Sample: The core is then sealed inside a titanium tube, protecting it from contamination and preserving its integrity for future study.
Why are these samples so important?
The samples collected by Perseverance are intended to be returned to Earth on a future mission, potentially in the 2030s. Once on Earth, these samples will be analyzed using advanced laboratory equipment that is too large and complex to be sent to Mars. These in-depth analyses could reveal:
- Evidence of Past Martian Life: The ultimate goal is to determine if life ever existed on Mars. The samples might contain fossilized microbes or other biosignatures.
- The History of Martian Climate and Geology: Studying the composition and structure of the rocks will provide clues about how Mars formed, how its climate changed over time, and whether it was ever habitable.
- Potential Resources for Future Martian Explorers: Analyzing the rocks could reveal the presence of valuable resources, such as water ice or minerals, that could be used to support future human missions to Mars.
What’s Next for Perseverance?
After collecting a sample from “Krokodillen,” Perseverance will continue its exploration of the Jezero Crater, searching for other interesting rock formations to sample. The rover is gradually making its way towards the ancient river delta that once flowed into the crater, a location that scientists believe is particularly promising for finding evidence of past life.
This mission is an ambitious endeavor that pushes the boundaries of our understanding of Mars and its potential to have once harbored life. As Perseverance continues its journey and gathers more samples, we draw closer to answering one of humanity’s biggest questions: Are we alone in the universe?
