Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.

First, it's required that the mole bounces back and partially out of the ground like it happened once already.
If we assume that this will happen a second time, I see two approaches: - A risky one, use the scoop to tilt the mole. Ensure that the force doesn't damage the mole. - A less risky, but more time-consuming approach: First dig a ramp with the scoop, then tilt the mole, cover it with soil, use the scoop to initially push onto the soil cover when hammering. Alternatively use the scoop to prevent the mole from bouncing like demonstrated already. If the risky approach fails and the mole ends up horizontally on the surface, the scoop will be needed to move the mole, to dig a ramp, to move the mole to the ramp, and to cover it with soil. If the mole remains stuck and neither forward nor backward motion is possible by hammering, we'll have a less trivial issue. I doubt that pulling at the teather would be an option. Scooping deep enough to free the mole will be a challenge. Scooping just to the mole might be feasible. This might change the behaviour of the mole. But it also bears a significant risk to be a dead-end. |

The vigorous interventions you describe, Gerald, are not supported by the level of interactivity and power levels on the lander. This would be the kind of thing someone might do with one of those arcade games where you pull the toy out with a crane, but Mars is 6 light minutes away and getting farther. A small action with the arm produces no feedback regarding the result until a photo would be taken and sent back to Earth. If the arm is in the way of the photo, it would need to be moved, then moved back. We might need for an orbiter to revolve into position to receive the photo, then transmit it to Earth when DSN bandwidth is available. And the power levels on the lander are at a premium, so they were looking at a 14-day cycle between interventions, 7 days in the better case.
This is not like building a model ship. It's like trying to get a trained dog to build a model ship while you yell commands through a windowless door. |
