Hayabusa Project By: Kirby Valentin Abstract The Hayabusa mission was the world’s first space mission to collect asteroid samples and return them to the Earth. The Hayabusa spacecraft was launched on May 9, 2003 towards Itokawa and returned to Earth on June 13, 2010. Objective The goal of my project was to create a space weathering map of the Itokawa asteroid.

Results
Itokawa• S type asteroid• dimensions: 535 x 294 x 209 m• 630 meters long and 250 meters wide• First asteroid to be the target of a sample return mission• Near earth potentially hazardous asteroid
Hayabusa• Solar powered, three-axis stabilized spacecraft that was pointed towards the Sun• Used an ion engine• Contains four scientific remote sensing instruments
Space Weathering• Space weathering is overtime exposure of airless bodies to different aspects of the space environment that results in their surfaces changing. • Space weathering causes areas to become darker because the smoother areas absorb more light. • Smoother areas absorb more light because they have more minerals like pyroxene and olivine.
Data Analysis Process • Retrieved data from Nasa Planetary Data System• Converted fits data to text data• Calculated Space Weathering Index with C program• Used perl script to generate spectral plot file which is used by gnuplot• Used Java Small Body Mapping Tool to better understand Itokawa
Future Work • Using the bidirectional reflectance distribution function to study the light scattering on Itokawa• Finding potential sources of clean energy on Itokawa or other asteroids
