MoonNEXT is a mission currently being studied, under the direction of the European Space Agency, whose launch is foreseen between 2015 and 2018. MoonNEXT is intended to prepare the way for future exploration activities on the Moon, while addressing key science questions. Exploration Objectives The primary goal for the MoonNEXT mission is to demonstrate autonomous soft precision landing with hazard avoidance; a key capability for future exploration missions. The nominal landing site is at the South Pole of the Moon, at the edge of the Aitken basin and in the region of Shackleton crater, which has been identified as an optimal location for a future human outpost by the NASA lunar architecture team [1]. This landing site selection ensures a valuable contribution by MoonNEXT to the Global Exploration Strategy [2]. MoonNEXT will also prepare for future lunar exploration activities by characterising the environment at the lunar surface. The potentially hazardous radiation environment will me monitored while a dedicated instrument package will investigate the levitation and mobility of lunar dust. Experience on Apollo demonstrated the potentially hazardous effects of dust for surface operations and human activities and so an understanding of these processes is important for the future. Life sciences investigations will be carried out into the effects of the lunar environment (including radiation, gravity and illumination conditions) on a man made ecosystem analogous to future life support systems. In doing so MoonNEXT will demonstrate the first extraterrestrial man made ecosystem and develop valuable expertise for future missions. Geological and geochemical investigations will explore the possibilities for In Situ Resource Utilisation (ISRU), which will be essential for long term human habitation on the Moon and is of particular importance at the proposed landing site, given its potential as a future habitat location. Science Objectives In addition to providing extensive preparation and technology demonstration for future exploration activities MoonNEXT will advance our understanding of the origin, structure and evolution of the Moon. These advances in understanding will come about through a range of geophysical and geochemical investigations. MoonNEXT will also assess the value of the lunar surface as a future site for performing science from the Moon, using radio astronomy as an example. The scientific objectives are: • To study the geophysics of the Moon, in particular the origin, differentiation, internal structure and early geological evolution of the Moon. • To obtain in-situ geochemical data from, within the Aitken Basin, where material from the lower crust and possibly the upper mantle may be found. • To investigate the nature of volatiles implanted into the lunar regolith at the South Pole and identify their species. • To study the environment at the lunar South pole, in particular to measure the radiation environment, the dust flux due to impact ejecta and micrometeoroids, and a possibly the magnetic field. • To study the effect of the lunar environment on biological systems. • To further our understanding of the ULF/VLF background radiation of the universe. • Investigate the electromagnetic environment of the moon at radio wavelengths with the potential to perform astronomical radio observations. Various mission scenarios are currently under study, incorporating options for a lander-only configuration or a lander with the possible addition of a rover. The working experimental payload includes cameras, broad band and short period seismometers, a radiation monitor, instruments to measure dust transport and micrometeoroid fluxes, instruments to provide elemental and mineralogical analyses of surface rocks, a mole for subsurface heat flow and regolith properties measurements, a radio antenna and a package containing a self sustaining biological system to observe the effects of the lunar environment. The addition of a rover, if shown to be feasible, would provide mobility for geochemical measurements, which is essential if geological units are to be examined in context. In the region around the South pole of the Moon investigations into excavated material related to the Aitken basin will require mobility to access the blocky ejecta fields associated with ~100m diameter craters. Mobility could also provide a means for the deployment of a network of short period seismometers for studies of regolith properties and the meteorite flux. The separation of the rover from the lander would provide a baseline for radio interferometry, which could provide the first ever image of the sky at wavelengths inaccessible from the Earth. MoonNEXT and the International Lunar Network In early 2008 NASA presented the concept of the International Lunar Network (ILN) this would comprise a network of several landers, provided by various countries and international agencies, which would be distributed at various locations across the surface of the Moon. Each of these landers would include a package for making geophysical measurements and their combined data set would provide detail on the internal structure and history of the Moon which is only possible through a globally distributed network. The proposed landing site, scientific instrument package and mission timescale for MoonNEXT mean that it is well suited as a European node to the ILN. Summary and Conclusions MoonNEXT is an ESA mission to the Lunar South Pole. MoonNEXT prepares the way for future exploration activities through technology demonstratin and characterisation of the landing site and its environment. In addition MoonNEXT addresses fundamental science questions relating to geophysics, geochemistry and the lunar environment. As a stand alone mission MoonNEXT provides a valuable step in the exploration and understanding of the Moon. This mission is also potentially an important European contribution to the International Lunar Network.
