NASA’s robotic probe In-Sight has detected and
measured a probable seismological tremor on Mars. This is the first time a
likely seismological tremor has been recorded on a planet other than the Earth
and its Moon. NASA has labelled the tremor a “Marsquake”.
Previously also tremors have been recorded but
this is the first recorded trembling that appears to have come from inside the
planet, as opposed to being caused by forces above the surface, such as wind.
The seismic event was recorded by In-Sight’s seismometer
called the Seismic Experiment for Interior Structure (SEIS).
InSight, short for Interior Exploration using
Seismic Investigations, Geodesy and Heat Transport, is a Mars lander. It seeks
to study the deep interior of the planet Mars. It also seeks to determine the
rate of Martian tectonic activity and meteorite impacts.
The mission is part of NASA’s Discovery Program
for highly focused science missions that ask critical questions in solar system
science. It is managed by NASA’s Jet Propulsion Laboratory.
The mission was launched in May 2018 aboard an
Atlas V-401 rocket. It had successfully landed at Elysium Planitia on Mars in
