Working papers on space research, chiefly on lunar samples, accrued by Colin Trevor Pillinger Papers primarily concern the United Kingdom's procural, distribution and analysis of lunar surface samples collected from the moon by the USSR unmanned spacecraft missions Luna 16 (1968), Luna 20 (1972) and Luna 24 (1976) and by NASA's Apollo missions 11, 12 and 14-17 (1969-1972). Also Apollo missions 18 and 19, which were proposed but never took place. Colin Pillinger was curator for the Luna 16, 20 and 24 mission samples given to the UK by the USSR and the papers that he accrued in this capacity span from the United Kingdom's first approaches to secure these moon rocks (instigated by Geoffrey Eglinton), through the allocation of the samples which was managed by a Royal Society Allocation Committe and a curatorial unit at the University of Bristol, to the publication of papers detailing the findings of the various research groups who were allocated samples for investigation. These groups were chiefly based in UK universities but there was also some international exchange of material. The papers include: international and domestic correspondence including with officers of the Royal Society and the USSR Academy of Sciences; documentation of the Royal Society Allocation Committees for Lunar Samples; notebooks documenting the separation, photography, analysis and distribution of samples; research notes; curatorial paperwork such as sample handling questionnaires and transfer agreements; other administrative papers; and copies of published papers and conference proceedings. There is some photographic material of the samples in the form of negatives, slides and photographic prints with accompanying notes. The Apollo and Mars mission material mostly originates from the University of Bristol, School of Chemistry where Geoffrey Eglinton was Principal Investigator for the research being conducted into the lunar samples and data, his co investigators were Colin Pillinger and J R Maxwell. There is also an earlier Apollo document from Eglinton's time at the University of Glasgow. The Apollo material also concerns the project to open Apollo 16 special surface samplers without compromising the lunar samples they contained. Colin Pillinger designed the scheme by which the samplers were opened. There are also some papers relating to other NASA space missions, as follows: A proposed return of samples from Mars to Earth which would have been a third phase of Mars exploration following on from the Mariner programme and Viking Probe in the 1970s. The Venus Pioneer. There are documents such as agenda and minutes from scientific committees that Pillinger was involved with, including: the international body - The Committee on Space Research 'COSPAR', and the UKs membership body for COSPAR - The British National Committee on Space Research, and its various subcommitees, most frequently the Planetary Sciences Sub Committee. 1966-1983
