is designed to stay in one place and deploy instruments onto the surface of Mars. To do that, it will use a robotic arm with a reach of 6 feet (2 meters).
The arm's Instrument Deployment Camera (IDC) is attached to its elbow, so it can monitor InSight and its surroundings.
A fresh IDC image from Tuesday shows the arm and a stowed-away grapple. The copper-colored device is a seismometer that will hunt for marsquakes. The dome-shaped object behind it is a wind and thermal shield for the instrument.
On the left side of the image, you'll see a black cylinder. This is the Heat Flow and Physical Properties Probe (HP3) that will drill deep into Mars to take the planet's temperature.
The InSight team is in no rush to deploy the investigative machines. The lander's cameras will continue to examine the area to help scientists determine where to place the instruments. It could be several months before the seismometer and drill get to work.
Another new image gives us a good look at the scoop and grapple on the end of the arm. We can also see a relatively smooth bit of Mars landscape near the lander.
