Dear Colleagues, Please join as a signatory <https://docs.google.com/spreadsheets/d/1p70Lj6WSUaS9mWIHMivHs_hv-lHOSGflhKR86fA2QFg/edit?usp=sharing> on our CAPTEM-affiliated white paper <https://drive.google.com/file/d/1aowUAU9fBdhMHn6CnP6gtp3vz_DSUl5d/view?usp=sharing> , *“Terrestrial recovery of extraterrestrial materials: Providing continued, long-term sample analysis opportunities for research and mission support”* to be submitted to the Planetary Decadal Survey 2023-2032 <https://www.nationalacademies.org/our-work/planetary-science-and-astrobiology-decadal-survey-2023-2032>. This white paper summarizes the scientific importance of the terrestrial recovery and resultant collections of extraterrestrial materials, including meteorites, micrometeorites and cosmic dust. It advocates for 1) continuing and expanding terrestrial recovery of extraterrestrial samples as an integral and critical support to small body and planetary missions and 2) developing and maintaining a high level of capability for sample curation and sample-analysis-based research by the research community.
