Video shows billion dollar InSight digging robot FINALLY working again after SEVEN months

NASA's digging probe on the InSight Mars lander is finally making progress again after assistance from the lander's robotic arm helped it gain purchase in the soil. The probe -- dubbed'the Mole' -- began hammering its way into the soil of the Red Planet in March, but after digging a few inches it found itself unable to go deeper. Experts believe that the probe encountered an unexpected layer of cemented soil that wasn't falling into the hole the device had dug. The result was that there wasn't enough purchase between the probe and the surrounding soil for the Mole to push down any deeper. After first trying to compact the surrounding soil with InSight's instrument arm, engineers tried pushing the mole sideways against its hole.
