NASA Spies InSight Mars Lander from Space as It Hunts Marsquakes

NASA's InSight lander has been busy on Mars preparing to begin scientific observations, and the mission passed another milestone this weekend, when the spacecraft began preparing to deploy its final instrument.

That instrument is the heat probe, which, if all goes well, will drill itself about 16 feet (5 meters) into Mars over the course of about two months. The deployment process, like that for the lander's seismometer, relies on the grapple-like claw at the end of InSight's robotic arm. As of yesterday (Feb. 10), the claw is grasping the heat probe in preparation for deployment.
