Science Objectives
LunarLeaper is a robotic mission concept designed to access and explore lunar lava tubes, using agile legged mobility to overcome hazardous terrain and enable in-depth investigation of these subsurface environments.
Investigate subsurface lava tubes
Confirm the existence and assess the extent of subsurface voids.
Assess the suitability of lava tubes for human exploration and habitation
Determine why collapse occurred and whether further collapse is likely. Assess availability of in-situ resources (ISRs). Determine the accessibility of the pit edge with potential future large robotic systems.
Assess geological processes, with a focus on the volcanic evolution of the Moon
Study key aspects of lunar volcanism exposed along the pit wall. Determine the number of flows, their volume, nature and their timescales. Paleoregolith layers might be present and could hold traces from the early Sun and Earth’s atmosphere. Connect local to more regional observations.
Investigate the local and regional extent of the regolith
Determine lateral and vertical extent of regolith. Assess properties of lunar regolith, including its composition, structure, and mechanical behavior, directly linked to mission design, landing safety, mobility, and the feasibility of in-situ resource utilization (ISRU) for future lunar exploration.
Operate a legged robot on the Moon
Employing and operating the first legged robot on an extraterrestrial surface, demonstrating new technological opportunities on the Moon and beyond.
Mission Concept
Mobility
LunarLeaper is based on the SpaceHopper design, building on the expertise of the legged robotics at ETH's Robotic Systems Lab (RSL).
Landing site
We want to explore the Marius Hills pit on the near side of the moon, a pit that is thought to be connected to a subsurface hollow lava tube.
Our plan is to land outside the hypothesized extent of the lava tube and traverse it twice, while taking some time at the pit itself.
Instruments
We combine geophysical measurements from the surface with imaging from the pit rim. The geophysical instruments are a gravimeter (GRAV) and a ground penetrating radar (GPR). For the imaging we use our dedicated science camera (SciCAM) and hopefully a spectrometer (SPEC). The legs of the rover can be used to to dig in the lunar soil to estimate mechanical properties.
