NASA’s InSight lander detects largest ever Marsquake
- NASA has reported that its InSight Mars lander has detected the largest quake ever observed on another planet.
- The rover first landed on Mars in November 2018, and has since heard 1,313 quakes.
- The largest previously recorded “marsquake” was detected in August 2021.
- On Earth, quakes are caused by shifts in tectonic plates.
- Mars, however, does not have tectonic plates, and its crust is a giant plate.
- Therefore, ‘marsquakes’ are caused due to stresses that cause rock fractures or faults in its crust.
- Significance: This quake is sure to provide a view into the planet like no other.
- Scientists will be analysing this data to learn new things about Mars for years to come.
About InSight lander
- It is studying the composition of Mars , how its material is layered, and how much heat seeps out of it.
- Importance: Earth and Mars used to be similar warm, wet and shrouded in thick atmospheres before they took different paths 3-4 billion years ago.
- Mars stopped changing, while Earth continued to evolve.
- With InSight, scientists hope to compare Earth and Mars, and better understand how a planet’s starting materials make it more or less likely to support life.
