Perseverance Rover Mission

Why in news?

• Perseverance Rover Mission (Under NASA’s Mars Exploration Program), has left a titanium tube containing a rock sample on the surface of Mars.
• It will serve as a backup if Perseverance can’t deliver its samples.

About Perseverance Rover Mission:

• The mission is designed to better understand the geology of Mars and seek signs of ancient life.
• Objectives:
  • Assess ancient habitability.
  • Demonstrate technology for future robotic and human exploration.
• Duration: At least one Mars year (about 687 Earth days).

Mission Steps:

• Collect:
  • Perseverance will collect rock and soil samples in cigar-sized tubes. The samples will be collected; the canisters will be sealed, and left on the ground.
• Fetch:
  • A Mars Fetch Rover (provided by the European Space Agency) will land, drive, and collect all samples from the different locations, and return to the lander.
• Transfer:
  • These samples will be transferred to the Mars Ascent Vehicle which will meet with an Orbiter.
• Return:
  • The Orbiter will carry the samples back to Earth.

About Perseverance Rover:

• Perseverance is the most advanced, most expensive and most sophisticated mobile laboratory sent to Mars.
• It is different from previous missions because it is capable of drilling and collecting core samples of the most promising rocks and soils, and setting them aside in a "cache" on the surface of Mars.
• It carries seven instruments, two microphones and 23 cameras in total in order to conduct unprecedented science and test new technology on Mars
• Power Source: A Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) which converts heat from the natural radioactive decay of plutonium (Plutonium Dioxide) into electricity.
