Getting down to business: NASA’s InSight lander lowers its seismometer to better hear sounds from the red planet’s interior

NASA’s InSight lander is leaning in for a better listen of Mars’ underground tremors.

The robotic explorer placed its seismometer on the surface at the end of last month, and is now getting even closer ‘for a better connection with Mars.’

This will help its instruments pick up fainter signals that may otherwise have been missed.

Days prior, InSight leveled out its seismometer and adjusted the internal sensors ahead of lowering everything down toward the ground.

‘It’s always good to be centered and balanced,’ the InSight Twitter account shared.

The lander also released the slack in its cable to keep it from fluttering around in the wind.

Now, NASA says the instruments have been positioned to the lowest point yet for the best possible listening opportunity.

‘My seismometer has now crouched down to its lowest level, for a better connection with Mars,’ the InSight Twitter account posted this week. ‘Faint signals are easier to hear if you keep your ear close to the ground.’

The InSight lander deployed its first instrument onto the surface of Mars around the end of December. 

Images from the lander show the seismometer on the ground, after it was lifted onto the surface by the lander’s robotic arm. 

It will record the waves traveling through the interior structure of the planet, and could help explain mysterious ‘marsquakes’ scientists believe occur regularly.  

At the time, NASA said the lander war performing flawlessly, and was ahead of schedule.
