The Planetary Science Institute studies the origin, characteristics, and evolution of planetary systems, including our solar system, Earth itself, and planetary systems around other stars. We convey the resulting knowledge to the scientific community, and to the public at large to promote science education and science literacy. We further use this knowledge to advance human activity in space and shape the future of robotic exploration of the solar system.

“Planetary Science Institute does not have committees that have authority to act on behalf of the governing body.”
“The CFO coordinates the preparation of the tax return with the Institute's independent auditing firm, which is selected by Board resolution. The Controller and CFO review the tax return line by line and discuss all elements of the return with the CEO. After final review and discussion, the CFO signs the tax return. Other members of the Board are provided a copy of the return prior to the return being filed.”
“Employees and Trustees are required to sign the COI policy upon onboarding. PSI's procurement policy requires purchases in excess of certain thresholds to have multiple quotes, mitigating the risk of paying excessive amounts to potentially conflicted parties. Direct cost purchases are scrutinized for compliance by PIs and Finance staff. Indirect cost purchases are scrutinized by Finance staff, including Controller, CFO, and CEO. Board of Trustees reviews quarterly financial reports.”
“Compensation for the CEO and CFO are reviewed, discussed, and approved by the Board of Trustees.”
“The organization's financial statements, governing documents, etc. are made available to the public upon request.”
“The Institute is exempt from federal income taxes under Section 501(c)(3) of the Internal Revenue Code. The Institute is also exempt from state income taxes. Accordingly, no provision for federal or state income taxes is recorded in the accompanying financial statements. Management is not aware of any matters which would cause the Institute to lose its tax-exempt status. However, income from certain activities not directly related to the Institute's tax-exempt purpose, may be subject to taxation as unrelated business income. Management has considered its tax positions and believes that all of the positions taken in its federal and state exempt organization tax returns are more likely than not to be sustained upon examination. The Institute's returns are subject to examination by federal and state taxing authorities, generally for three years and four years, respectively, after they are filed. The Institute recognizes interest and penalties related to unrecognized tax benefits in operating and general expenses in the accompanying financial statements. During the years ended September 30, 2023 and 2022, the Institute did not recognize any interest and penalties.”

| IRS990/Desc | 0 | The Planetary Science Institute (PSI) is a nonprofit science research and educational organization with an established record of excellence in solar system exploration, comparative planetology, science education and public outreach. PSI has scientists in 35 states, the District of Columbia, and other locations around the world. In the fiscal year ending September 30, 2023, PSI scientists operated instruments on NASA's Mars Science Laboratory and JUNO missions and provided science team support for these and NASA's Mars Reconnaissance Orbiter, Lunar Reconnaissance Orbiter, Psyche, New Horizons mission, and ESA's Mars Express. They are unveiling Mercury's geological mysteries, identifying potential salt glaciers and evidence of a primordial atmosphere. They have discovered new volcanic processes on the Moon and a large volcanic outburst on Io.The PSI Observatory continues to be used in the study of Jupiter's Io torus, the observation of comets, exoplanets and other bodies. PSI scientists are identifying the distribution of buried water ice resources on the Moon and Mars that may be important for future human exploration, they support an instrument on the International Space Station to study the climate effects of dust (particularly from North Africa).PSI scientists were awarded research grants and contracts to conduct diverse research and laboratory studies covering the Moon, Mars, asteroids, comets, meteorites, outer planet satellites, solar system dynamics, solar system origins, planets around other stars, and other areas.PSI is responsible, as part of NASA's Planetary Data System, for archiving all mission data involving asteroids, comets and interplanetary dust and making it available to the general science community and public. PSI scientists engaged in public outreach through art, writing children's books, popular science books, and public lectures and broadcast events such as Discovery Channel and BBC specials. |

| IRS990ScheduleD/SupplementalInformationDetail/ExplanationTxt | 0 | The Institute is exempt from federal income taxes under Section 501(c)(3) of the Internal Revenue Code. The Institute is also exempt from state income taxes. Accordingly, no provision for federal or state income taxes is recorded in the accompanying financial statements. Management is not aware of any matters which would cause the Institute to lose its tax-exempt status. However, income from certain activities not directly related to the Institute's tax-exempt purpose, may be subject to taxation as unrelated business income. Management has considered its tax positions and believes that all of the positions taken in its federal and state exempt organization tax returns are more likely than not to be sustained upon examination. The Institute's returns are subject to examination by federal and state taxing authorities, generally for three years and four years, respectively, after they are filed. The Institute recognizes interest and penalties related to unrecognized tax benefits in operating and general expenses in the accompanying financial statements. During the years ended September 30, 2023 and 2022, the Institute did not recognize any interest and penalties. |
