NASA’s Mars Rover collected its First Rock Sample

Newest Mars rover of the American Space Agency, NASA has successfully collected the first rock sample for return to the Earth.


  • Rock sample was termed as the perfect core sample by the Perseverance rover’s chief engineer, Adam Steltzner.
  • In earlier attempt, Perseverance drilled into much softer rock to crumble the sample, but it didn’t get inside the titanium tube. Then the rover drove a half-mile for a better sampling spot to drill again.
  • Perseverance arrived at the Jezero Crater of Mars in February 2021.
  • The Jezero Crater is believed to be the home of a lush lake-bed and river delta billions of years ago.
  • Thus, this mission was launched in search of rocks that could reveal about ancient life.
  • NASA has planned to launch more spacecraft to get samples collected by Perseverance.
