The Michael J.S. Belton and Anna Don Fund was established by Michael J.S. Belton and Anna Don to support biennial symposiums with a focus on the origins, physical structure and composition of comet nuclei. Dr. Belton was a leader of the planetary science community and made fundamental contributions to cometary science. He was also a member of PSI’s Board of Trustees. His passion for science lives on through the support of this fund.

 The Betty Pierazzo Memorial Fund honors PSI Senior Scientist Betty Pierazzo, an internationally noted planetary impact scientist and educator. This fund supports the Pierazzo International Student Travel Award, which is given annually to an American graduate student to attend a planetary meeting outside the US and to a non-US graduate student to attend a planetary meeting within the US, promoting international collaborations.

Education and Public Outreach.  Turn on the television, open a newspaper or a news magazine and you will read about the need to improve STEM education. We are doing our part to make a difference in the Tucson and Southern Arizona area, and extending our programs to other parts of the United States. When you hear someone saying “every gift makes a difference,” that is so very true for our education programs.
