Nasa’s InSight lander

Topics Covered: Awareness in space.

Nasa’s InSight lander:


Context:

Nasa’s InSight lander has recorded over 500 quakes to date on Mars since its touch down on the Red Planet in November 2018.

  • The two recent quakes of magnitude 3.3 and 3.1 originated in a region called Cerberus Fossae.
  • These findings support the idea that the planet is seismically active.

About InSight Mission:

  • InSight is part of NASA’s Discovery Program.
  • It will be the first mission to peer deep beneath the Martian surface, studying the planet’s interior by measuring its heat output and listening for marsquakes, which are seismic events similar to earthquakes on Earth.
  • It will use the seismic waves generated by marsquakes to develop a map of the planet’s deep interior.

Significance of the mission:

  • The findings of Mars’ formation will help better understand how other rocky planets, including Earth, were and are created.
  • InSight would delve deep beneath the surface of Mars, detecting the fingerprints of the processes of terrestrial planet formation, as well as measuring the planet’s “vital signs”: Its “pulse” (seismology), “temperature” (heat flow probe), and “reflexes” (precision tracking).

InSight seeks to answer one of science’s most fundamental questions: How did the terrestrial planets form?
