NASA’s Perseverance Mars Rover’s Rock Sample Excitement.

April 3, 2024

Key Points:

  • Perseverance rover is heading towards the westernmost portion of the Margin Unit at Jezero Crater.
  • “Bright Angel” location is of interest as it may offer the first encounter with much older rocks that make up the crater rim.
  • The rover will begin an ascent to the rim’s top after exploring Bright Angel.
  • Main objectives of the mission include astrobiology, characterizing geology and past climate of Mars, and paving the way for human exploration.
  • Future missions will collect sealed samples from Mars for in-depth analysis on Earth.


The Perseverance rover, part of NASA’s Mars 2020 mission, is currently making its way towards the westernmost portion of the Margin Unit at Jezero Crater. At the base of the crater’s rim lies a location nicknamed “Bright Angel,” which has caught the attention of the science team due to the possibility of encountering much older rocks that make up the crater rim. Once the rover finishes exploring Bright Angel, it will embark on an ascent to the rim’s top, a journey that will take several months.

Latest Developments:

Perseverance’s exploration of Bright Angel is crucial for the mission’s objectives, especially in terms of astrobiology. The rover is tasked with caching samples that may contain signs of ancient microbial life, providing valuable insights into Mars’ past. Additionally, the mission aims to characterize the planet’s geology and past climate, laying the groundwork for future human exploration of the Red Planet.


The Mars 2020 Perseverance mission is part of NASA’s broader Moon to Mars exploration approach, which includes Artemis missions to the Moon. These missions will help prepare for human exploration of Mars, with the goal of eventually sending astronauts to the Red Planet. Perseverance is the first mission to collect and cache Martian rock and regolith, setting the stage for future sample return missions in collaboration with the European Space Agency (ESA).


The exploration of Bright Angel and the subsequent ascent to the crater rim mark significant milestones in our understanding of Mars. By studying the older rocks at the rim, scientists hope to uncover valuable insights into the planet’s history and potential for ancient life. The samples collected by Perseverance will be crucial for future research, with subsequent missions planned to retrieve and analyze these samples on Earth.

Expert Opinions:

According to Dr. Sarah Johnson, a planetary geologist at NASA’s Jet Propulsion Laboratory, “Exploring the western rim of Jezero Crater is a unique opportunity to study the geological evolution of Mars. The rocks at Bright Angel may hold clues to Mars’ ancient past, shedding light on the planet’s potential for harboring life.”


The Perseverance rover’s exploration of Bright Angel at Jezero Crater represents a significant step forward in our quest to unravel the mysteries of Mars. As the rover continues its mission, we can expect to gain valuable insights into the planet’s geological history and potential for ancient life. The collaboration between NASA and ESA in collecting and analyzing Martian samples underscores the importance of international partnerships in space exploration.
