Exploring Near-Earth Asteroids: CARI Research Proposal Presentation by Tony George

This presentation by Tony George at the IOTA 2013 Conference outlines a research proposal from the Cascadia Airless Research Institute (CARI) aimed at characterizing the properties of Near-Earth Asteroids (NEAs). The research focuses on six key areas: regolith characterization, thermophysical properties, surface hydroxylation, space weathering effects, sample return technology, and physical measurements of NEAs. Utilizing advanced observational techniques, the project aims to improve measurements of NEA size and shape, enhancing our understanding of these celestial bodies.

Presentation Transcript

  1. Cascadia Airless body Research Institute (CARI) Near Earth Asteroid (NEA) National Science Foundation (NSF)Research Grant Proposal Presentation by Tony George At IOTA 2013 Conference

  2. AASTA 1 – University of Washington (UW) 2 – Central Washington University (CWU) 3 – Columbia Basin College (CBC) 4 – Heritage University (HU) 5 – Whitman College (WC) 6 – The Alliance for the Advancement of Science Through Astronomy (AASTA) 7 – Bear Fight Center (BFC) 8 – Lunar and Planetary Institute (LPI) 9 – Pacific Science Center (PSC) 10 – Planetary Resource, Inc. (PRI)

  3. Proposed Research The research goal of CARI will be to characterize the properties of observed NEAs and generate a comparative analysis between different NEAs and between NEAs and the Moon.

  4. Characterization will occur in six Focus Areas: Focus Area 1 – Characterizing the Regolith via IR Measurements Focus Area 2 – Thermophysical Properties and Volatile Content Focus Area 3 – Characterizing Surface Hyroxylation Focus Area 4 – Understanding the Effects of Space Weathering Focus Area 5 – Sample Return Technology Development Focus Area 6 – Physical Measurements of NEAs

  5. Focus Area 6: Physical Measurements of NEAs (using asteroid occultation and light curve measurements) • Precise measurement of size and shape of NEAs by occultations of stars. Multi-chord observations during the same event or multi-chord observations obtained through multiple events. • Precision photometry of NEAs to determine spin rate, size and shape using one or more of the following shape models : Interactive Service for Asteroid Models (ISAM) Database of Asteroid Models from Inversion Techniques (DAMIT) Miriade(The Virtual Observatory Solar System Object Ephemeris Generator) • Precision astrometry for the improvement of star positions and NEA orbital elements for improved predictions of occultations prior to events.

  6. Equipment 1. Columbia Basin College Robert and Elizabeth Moore Observatory. 2. Pacific Northwest Regional Observatory (PNWRO). 3. High speed/high sensitivity CCD and CCD Video cameras

  7. 5-Year DurationGrant award to be decided in November 2013If successful, I would be one of the principle investigators on Focus Area 6
