Deep Impact – A NASA Discovery Mission RSC’s HAWAII-1 R will analyze 4. 5 -billion-yr-old comet dust, never accessed before! • Reason for mission: “There are many theories about comets that are unconstrained by observation” – M. O’Hearn, PI, Univ of Maryland • Will tell us about the beginning of our solar system • Deep impact scheduled to occur on 4 th of July, 2005 HAWAII-1 R #103 • Comet Tempel-1 : a 4. 5 billion-year-old time capsule • Spacecraft will be recording visible and IR data during and after the impact – using a high resolution spectroscopy instrument featuring RSC’s 4. 8 um cutoff HAWAII-1 R in custom flight packaging Jan. 13 photograph taken by Mt Palomar's 200 inch telescope as the Deep Impact spacecraft was at a distance of about 260, 000 kilometers (163, 000 miles) from Earth and moving at a speed of about 16, 000 kilometers per hour (10, 000 miles per hour). 2/27/2021 Chart 6
