Graphene Flagship partners University of Cambridge (UK) and Université Libre de Bruxelles (ULB, Belgium) paired up with the Mohammed bin Rashid Space Centre (MBRSC, United Arab Emirates), York University (Canada) and the European Space Agency (ESA) to test graphene on the Moon.
The Rashid rover is planned to be launched on Nov. 30, 2022 from Cape Canaveral in Florida and will land on a geologically rich and as yet only remotely explored area on the Moon’s nearside – the side that always faces the Earth. During one lunar day, equivalent to approximately 14 days on Earth, Rashid will move on the lunar surface investigating interesting geological features.
The Rashid rover wheels will be used for repeated exposure of different materials to the lunar surface. As part of this Material Adhesion and Abrasion Detection experiment, graphene-based composites on the rover wheels will be used to understand if this material can protect spacecraft against the harsh conditions on the Moon, and especially against regolith (also known as ‘lunar dust’).
Regolith is made of extremely sharp, tiny and sticky grains and, since the Apollo missions, it has been one of the biggest challenges lunar missions have had to overcome. Regolith is responsible for mechanical and electrostatic damage to equipment and is therefore also hazardous for astronauts. It clogs spacesuits’ joints, obscures visors, erodes spacesuits and protective layers, and is a potential health hazard.
The University of Cambridge researchers have produced additively manufactured graphene/polyether ether ketone (PEEK) composites. The interaction of these composites with the Moon regolith (soil) will be investigated.
“Being able to follow the Moon rover’s progress in real time will enable us to track how the lunar environment impacts various types of graphene-polymer composites, thereby allowing us to infer which of them is most resilient under such conditions. This will enhance our understanding of how graphene-based composites could be used in the construction of future lunar surface vessels,” said Sara Almaeeni, MBRSC science team lead, who designed Rashid’s communication system.
“New materials such as graphene have the potential to be game changers in the future human space exploration. In combination with the resources available on the Moon, advanced materials will enable radiation protection, electronics shielding and mechanical resistance to the harshness of the Moon’s environment. The Rashid rover will be the first opportunity to gather data on these new materials’ behavior within a lunar environment,” added Carlo Iorio, Graphene Flagship space champion, from partner ULB.
Leading up to the Moon mission, a variety of inks containing graphene and related materials, such as conducting graphene, insulating hexagonal boron nitride and graphene oxide, semiconducting molybdenum disulfide, prepared by the University of Cambridge and ULB were also tested on Materials Science Experiment Rocket 15 (MASER 15) mission, successfully launched on Nov. 23, 2022 from the Esrange Space Center in Sweden.
This experiment, named ARLES-2 (Advanced Research on Liquid Evaporation in Space) and supported by European and UK space agencies (ESA, UKSA) included contributions from Graphene Flagship Partners University of Cambridge (UK), University of Pisa (Italy) and Trinity College Dublin (Ireland), in collaboration with Aix-Marseille University (France), Technische Universität Darmstadt (Germany), York University (Canada), Université de Liège (Belgium), the Chinese Academy of Sciences (China), Institute of Thermo-physics (Russia), University of Edinburgh (UK), Loughborough University (UK), the European Space Agency (ESA), the Swedish Space Corporation (SSC), and Khalifa University (UAE), which joined this year – coordinated by Graphene Flagship Partner Université Libre de Bruxelles (Belgium).
This experiment will provide new information about the printing of GMR inks in weightless conditions, contributing to the development of new addictive manufacturing procedures in space such as 3D printing. Such procedures are key for space exploration, during which replacement components are often needed, and could be manufactured from functional inks.
“The Graphene Flagship is spearheading the investigation of graphene and related materials (GRMs) for space applications. In November 2022, we had the first member of the Graphene Flagship appointed to the ESA astronaut class. We saw the launch of a sounding rocket to test printing of a variety of GRMs in zero gravity conditions, and the launch of a lunar rover that will test the interaction of graphene—based composites with the Moon surface,” said Andrea Ferrari, director of the Cambridge Graphene Centre and Science and technology officer of the Graphene Flagship.
“Composites, coatings and foams based on GRMs have been at the core of the Graphene Flagship investigations since its beginning. It is thus quite telling that, leading up to the Flagship’s 10th anniversary, these innovative materials are now planned to be tested on the lunar surface. This is timely, given the ongoing effort to bring astronauts back to the Moon, with the aim of building lunar settlements. When combined with polymers, GRMs can tailor the mechanical, thermal, electrical properties of then host matrices. These pioneering experiments could pave the way for widespread adoption of GRM-enhanced materials for space exploration,” said Ferrari.
