    An ESA small mission candidate to explore lunar caves

  • Our questions and goals

    Question 1: Is there a lava tube under Marius Hills?

    We use geophysical sounding methods to detect a potential void, i.e. a lava tube connected to the pit hole and map its extent. By comparing to the extent of the rille on the surface, we can give ground truth to orbital measurements.

    Question 2: Is the lava tube stable enough to be used as a human habitat?

    We investigate the fault map on the rim of the pit hole to find out why it collapsed and whether its flanks are stable now. This is necessary before a large rover or even humans might be send for further exploration.

    Question 3: Which volcanic processes formed the tube and the pit?

    The layers along the pit wall have recorded the history of volcanic eruptions in Marius Hills. We investigate characteristics such as thickness and composition of these layers - a window into the lunar past.

    Question 4: What is hidden inside the regolith around the pit?

    Our radar and optical system will detect whether there are ancient pieces of paleoregolith below ground. These could hold traces from the early sun and Earth's atmosphere. Regolith at the surface is more eroded but still imporant because this is the material we need to move in and this is why we will also explore surface mechanical properies.

    Mobility

    LunarLeaper is based on the SpaceHopper design, the result of 4 years of iteration at ETH's Robotic Systems Lab (RSL). The robot only weighs ~10 kg.

    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 (SCAM) and hopefully a spectrometer (SPEC). The legs of the rover can be used to to dig in the lunar soil to estimate mechanical propoerties.

    Consortium

    We build on a team from 5 small ESA member states: Switzerland, Belgium, Norway, Poland and Luxembourg.
