Lucy Exploring Jupiter’s Trojans Peter Haun and Cari Schuette

Who was Lucy? ●Ancient hominid ●Found in Ethiopia in 1974 ●Found 40% of the skeleton ●Led us to greater understanding of humans origin and past ●Skeleton dates from sometime between 3.22 and 3.18 million years ago

Where we’re going Launch, October EQ5- main belt, April Eurybates- C-type Trojan, August TS25- SEO April VQ10- D-type Trojan, October Patroclus- P-type Trojan binary, March 2032

Trojans (and Greeks) - Asteroids which share their orbit with other planets or moons - Do not collide with it because they orbit in one of the Lagrangian points of stability - Potentially Kuiper Belt objects or accumulation of protoplanetary disk

What do we expect to learn from this? Questions we hope to answer: ●What were the initial stages, conditions and processes of Solar System formation? ●How did the giant planets accrete, and is there evidence that they migrated to new orbital positions? ●What governed the accretion, and what roles did bombardment by large projectiles play? ●What were the sources of primordial organic matter? ●What are the differences in the properties of the Kuiper Belt objects versus those within the orbit of the planets?
