The Moon Lightweight Interior and Telecoms Experiment (MoonLITE), is a proposed British space mission to explore the Moon and develop techniques for future space exploration. If funded, it will be built by a consortium of UK industry likely including Surrey Satellite Technology Ltd, and it is planned to be launched into lunar orbit in 2014. The mission concept emerged from a study run by the Particle Physics and Astronomy Research Council (now the Science and Technology Facilities Council) in 2006. In December 2008, the British National Space Centre (part of the UK Space Agency since April 2010) announced that the project was moving to Phase A study. This is a 12-month study of the mission system, the penetrators and the penetrator descent systems.
The mission has both scientific and technological goals. The science goals are concerned with the interior structure, history and current state of the Moon. MoonLITE would deploy four one metre-long penetrators into the lunar surface in order to emplace a global network of seismometers, heat flow sensors and - possibly - volatile detectors. This would allow the internal structure of the Moon to be determined as well as exploring the frequency and origin of moonquakes. It would be the first space mission dedicated to studying the interior structure of the Moon since the experiments emplaced by the Apollo astronauts. Beyond the scientific value, the enhanced knowledge of the seismic environment would support engineering design and safety requirements for a future human lunar outpost.
One of the technological goals is to demonstrate for the first time a lunar telecommunications network able to communicate with four stations on the lunar surface and relay data back to Earth. Such a comms network would be needed for future robotic and lunar explorers, especially for a human outpost located near the South Pole where line of sight communications would be limited. Another objective is to prove the feasibility of penetrators for deploying scientific payloads. Although extensive work has been carried out on the technique in the US and Japan, the only attempt to use penetrators - the Deep Space 2 vehicles aboard NASA's Mars Polar Lander - was unsuccessful. Penetrators could be used at Mars, to deploy a seismic network; at Europa in order to measure the thickness of the ice sheet; and at Enceladus to investigate the fissures discovered by Cassini.
