Nasa's InSight deploys 'Marsquake' instrument
By Jonathan Amos
BBC Science Correspondent
20 December 2018
The American space agency's InSight mission to Mars has begun to deploy its instruments.
The lander's robotic arm has just placed the bell-shaped seismometer package on the ground in front of it.
This suite of sensors, developed in France and the UK, will listen for "Marsquakes" in an effort to determine the internal structure of the Red Planet.
. . .
As well as the seismometer experiment, InSight is equipped with a heat probe that will burrow into the ground, and a very sensitive radio experiment that will measure how the planet wobbles on its axis.
