T213-04MM
Ultrasonic Tools for Planetary Surface Exploration
The suitability of ultrasonic tools, e.g. for coring and drilling to limited depth (or generally sample acquisition and
transportation) shall be studied and demonstrated with adequate hardware. A small initial feasibility study has been carried out
by Leicester University in the frame of the AURORA programme, and has encouraged the use of ultrasonic tools for miniature
sampling devices. Compared with classical mechanical corers and drills, ultrasonic equipment is very robust and simple as it
does not require a high number of moving parts or a sophisticated drive mechanism. Several actuator types and mechanical
amplifiers shall be studied. A major constraint is expected with the typical electric power limitations of planetary landing
missions. Furthermore, the interaction of ultrasound with rock and softer materials is largely unknown.
Deliverables:
Demonstrator Model(s), including the ultrasonic transducer and drive electronics.

Title:
Imaging Lidar technology
Nowadays Imaging Lidars can perform measurements up to few kilometres at typical distance resolutions of a few centimetres
at a rate of a few kHz. Imaging Lidars can support a number of space applications on orbiter modules, landers and planetary
rovers like surface mapping, hazard avoidance and safe landing, navigation, multiple spacecraft operations (rendez-vous and
docking), target properties recognition. However, since most of these systems rely on complex scanning mechanisms, they
are bulky and often too heavy for future solar system exploration missions. The recent emergence of novel and advanced
technologies like new 2-dimensional detector arrays (APD or CMOS arrays) and optical micro components (like MEMS and
MOEMS) will bring a new trend in the development of compact, high resolution and multi-task sensor Imaging Lidars. This
activity shall study the use of these novel technologies, assess the impact on the Lidar performances and develop an Imaging
Lidar proof-of-concept breadboard that validates these technologies, making the Imaging Lidar a feasible instrument for space
applications in the frame of AURORA.
Deliverables:
Imaging Lidar breadboard.

Title:
Down hole hammering Mechanism
The objective is to develop a high-energy (0.5-2 J/impact) hammering system, that can be placed inside the drill string (20-40
mm in diameter). Power generation can utilize an electric motor, but shape memory alloys and piezo-elements (operating in
an inch-worm manner) can be considered as an option. An optional passive mechanism to take impact power directly from the
drill rotation (without any additional power sources and power feed-through) can also be considered. Impact frequency will be
limited by the power of the actuator; however, impact energy must be kept at a level high enough to provide the desired effect.
Deliverables:
Breadboard of a drill- hammering device.
