| Zusammenfassung |
| We will report on the possibility of using the scoop attached to the instrument deployment
arm to perform soil mechanical experiments directly on the surface of Mars. The Phoenix
mission flown 2009 had an instrument deployment arm which was also used to sample
surface material indo instruments mounted on the lander deck. The flight spare
of this arm will again be flown to Mars on board the InSight mission. Although,
the primary purpose of the arm and the attached scoop was not soil mechanical
investigations it was already demonstrated by the Phoenix mission that the arm can be
used to perform auxiliary investigations of the surface materials. We will report
on modelling efforts using a Discrete Element Software package to demonstrate
that simple soil mechanical experiments can be used to derive essential material
parameters like e.g. angle of repose and others. This is of particular interest since it
would be possible to implement experiments using the hardware of the InSight
mission.

deposed material which both can be used to derive soil mechanical parameters. |
