NASA’s Perseverance rover

General Studies-3

Topics Covered: Awareness in Space


Context: NASA’s Perseverance rover has successfully collected its first rock sample for return to Earth. NASA has called it a perfect core sample.

  • NASA plans to launch more spacecraft to retrieve the samples collected by Perseverance.
  • Perseverance arrived in February 2021 at Mars’ Jezero Crater, the site on an ancient lake— in search of rocks that might hold evidence of ancient life.


Why is this mission significant?

  • It carried a unique instrument, MOXIE or Mars Oxygen ISRU Experiment: which for the first time manufactured molecular oxygen on Mars using carbon dioxide from the carbon-dioxide-rich atmosphere (ISRU means In Situ Resource Utilization: or the use of local resources to meet human needs or requirements of the spacecraft).
  • It carried Ingenuity,the first ever helicopter to fly on Mars.
  • It is the planned first step to bring back rock samples from Marsfor analysis in sophisticated laboratories on Earth: with the goal of looking for biosignatures: or signatures of present or past life.


These are some of the key mission objectives:

  • Look for signs of ancient microbial life.
  • Collect Martian rock and dust samples for later return to Earth.
  • Deliver an experimental helicopter.
  • Study the climate and geology of Mars.
  • Demonstrate technology for future Mars missions.


What is the reason for the near-term interest in Mars?

  • Mars is located in the very near backyard (about 200 million km away).
  • It is a planet that humans can aspire to visit or to stay for a longer duration.
  • Mars had flowing water and an atmosphere in the distant past: and perhaps conditions to support life.
  • It also has implications for commercial travel.
