Microgravity Research

This is a rather esoteric subject on the face of it, so I should like to explain why I have chosen it. I am vice-chairman of the parliamentary space committee, and as a consequence of that role I have come into contact with many people in the space industry who have spoken to me about microgravity, the research thereof and its potential value to the British economy. I do not have any direct constituency link, although I have a local company that provides equipment for satellites. In the past decade, the UK space industry has been growing, year on year, in excess of 10%. I genuinely think that it should be part of the Government's growth strategy and that it would contribute to the diversification of this country's economic base. I have had the particular pleasure of meeting Tim Peake, who is the only British astronaut on the European Space Agency manned programme, and who also happens to be a champion of microgravity. That is quite important, because it indicates how good we are in Britain at research in this area. Why have microgravity research? First, as I said, the UK is very strong in that area. Microgravity crosses a large number of fields, and that may contribute to why it has not always received support from the research councils. Secondly, it has huge potential economic benefits, particularly in bio-medicine. Thirdly, I do not think I am alone in this House in thinking that we should have a manned space flight programme. We need to do that with partners—perhaps with Europe, Russia or the United States—but I genuinely believe that we are better off seeking out new knowledge, endeavour and aspiration. All those things are positives, and Britain was at its best when it was displaying those facets. Let me explain the structure of my speech. First, I will explain microgravity. I am sure that all colleagues here understand it fully and do not need a definition, but I will provide it for the benefit of the many people who have tuned into BBC Parliament for this debate. I will then touch on the sectors that microgravity research can impact on; talk about the history of the involvement in microgravity research, or the lack thereof, of Governments, this one and previous; and put some questions to the Minister. As life evolved on this earth, lots of physical and chemical change took place in the environment that caused adaptations to take place in life, be it plant or animal. The only thing that has been constant in 4.8 billion years is gravity. It is therefore thought that organisms now have little or no genetic memory of how they would respond to low gravity, and that the low-gravity environment could uncover some novel mechanisms and responses to adaptations that may benefit the economy through commercial applications. That is basically why researchers are so eager to get into space, so to speak, to test the impact of microgravity. This definition is just one of many I have read:"““Microgravity research = the research into the impact of low or zero gravity on human health and on other materials, and the exploitation of the low gravity environment to conduct research into pure science and human applications.””" We can create such low gravity here on earth in drop towers—something like those found at Alton Towers—or through parabolic flights. However, the best place for it to happen is in space. It can be done by a sounding rocket; at the moment, it is done at the international space station. Why conduct the research? Put simply, gravity adds complexity to certain experiments by contributing to convection currents, shear stresses and buoyancy, and that can impact on processes that we would like to study. In order to try to remove those potentially confounding variables from the experiment, one needs to go into a microgravity environment, and the best place for that is in space. Let me turn to the sectors that may be impacted on, both economically and in terms of human knowledge and pushing back these boundaries. First, I will mention bio-medicine; as a doctor, I would be expected to do so. The bio-medical applications are numerous. Essentially, it is thought that putting cells—any cells—into a microgravity environment affects the way in which they work. Understanding how cells work and how they communicate with one another will have broad applications in the study of cancer, coronary heart disease, AIDS and diabetes. We can all understand that that might lead to the development of new therapies and drugs that would benefit mankind. In economic terms, if British patents were attached to such developments, UK plc would benefit. One can also grow pure protein crystals in microgravity, and by doing so aid the understanding of the immune system, which would again benefit health care. One of the most noted areas is musculoskeletal systems and the response of bone and muscle. I am sure that most hon. Members know that spacemen who have spent lots of time in space have been found to have reduced bone density and muscle wastage. Why that happens is not fully understood. By trying to understanding that and how tissue remodels, we may very well find new techniques to treat musculoskeletal disorders. Another sector where microgravity can be used is fluid physics. The understanding of the forces that affect fluids has wide applications. If we can understand them better, it might contribute to the miniaturisation of electronic devices. The BlackBerrys and laptops that we use have all benefitted from greater knowledge in this area. Using these developments will undeniably lead to a reduction in costs for the customer when they buy such electronic devices at John Lewis and elsewhere.
