InSight Just Placed its Seismometer onto the Surface of Mars to Listen for Marsquakes

NASA’s InSight lander has deployed its first instrument on the surface of Mars. On December 19th, the stationary lander used its robotic arm to deploy the SEIS (Seismic Experiment for Interior Structure), marking the first time a seismometer has been placed on the surface of another planet. This is a milestone for the mission, and one that comes well ahead of schedule.

InSight landed on Mars at Elysium Planitia on November 26th. Since then, it’s been checking out its immediate surroundings with its cameras to find the perfect spot to deploy the seismometer, and its other deployable instrument, the HP3 (Heat Flow and Physical Properties Package.) Mission planners allocated several weeks for instrument site selection, so this is well ahead of schedule.

Of Course You’ll Want to See InSight’s First Selfie.

InSight has been on the Martian surface for almost three weeks, prepping itself for all the science it’s going to do. But in the meantime, it’s doing what any self-respecting, modern robotic lander does: Taking pictures of itself. And now NASA has released InSight’s first selfie for all the lander’s adoring fans and Instagram followers.

InSight is on Mars to study the interior of the rocky planet, and provide clues into how rocky planets form, both here in our Solar System, and in distant systems. It’s got a suite of instruments to do that with, including a device that will drill 5m (16 ft.) deep into the planet to measure how heat flows through the core of Mars. But it’s taking a cautious approach to that, using its time wisely to select the perfect spot to deploy its instruments.

In the meantime, holiday snaps!

InSight Uses its Seismometer to “Hear” the Sound of Wind on Mars

Just two weeks ago, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander touched down on the surface of Mars. In the hours that followed, mission controllers at NASA-JPL received confirmation that the lander had deployed its solar arrays and was commencing scientific operations.

And in what was sure to be a treat for space exploration enthusiasts, the lander recently provided the first ever experience of what it “sounds” like to be on Mars. The sounds were caught by an air pressure sensor inside the lander and the seismometer instrument that is awaiting deployment to the surface. Together, they recorded the low rumble caused by Martian winds that blew around the lander’s location on Dec. 1st.

InSight’s Robot Arm is Ready to go to Work

This image was taken by the InSight Lander's Instrument Deployment Camera mounted on the lander's robotic arm. The stowed grapple on the end of the arm is folded in, but it will unfold and be used to deploy the lander's science instrument. The copper-colored hexagonal object is the protective cover for the seismometer, and the grey dome behind it is a wind and thermal shield, which will be placed over the seismometer after its deployed. The black cyliner on the left is the heat probe, which will drill up to 5 meters into the Martian surface. Image: NASA/JPL-Caltech

Some new images sent home by the InSight Lander show the robotic arm and the craft’s instruments waiting on deck, on the surface of Mars. The lander is still having its systems tested, and isn’t quite ready to get to work. It’ll use its arm to deploy its science instruments, including a drill that will penetrate up to 5 meters (16 ft.) deep into the Martian surface.

Mars InSight Lands on November 26th. Here’s where it’s going to touch down

In the course of exploring Mars, the many landers, rovers and orbiters that have been sent there have captured some truly stunning images of the landscape. Between Spirit, Opportunity, Curiosity, the Mars Reconnaissance Orbiter (MRO) and others, we have treated to some high-definition images over the years of sandy dunes, craters and mountains – many of which call to mind places here on Earth.

However, if one were to describe the region where NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander will be landing (on Nov. 26th, 2018), the word “plain” would probably come to mind (and it would be appropriate). This region is known as Elysium Planitia, and it is where InSight will spend the next few years studying Mars’ interior structure and tectonic activity for the sake of learning more about its history.
