  1. quakerattleand roll Josh Smith Zachary Blunier Michael Krauz Matt Pensa Daniel Lane Trey Keown

  2. science objectives • Determine the inner structure of Europa • Rough surface suggests inner geological activity • Caused by either strong tremors or a flowing subsurface ocean • Very interesting candidate for extraterrestrial life

  3. operational strategy • Deploy Seismometer Measurement Mechanisms (SMM) at predetermined locations • Transfer seismic data back to orbiter as it orbits above

  4. payload specs SMM EDID • Two components: EDID and SMM • EDID is launcher (double-barreled shotgun) • SMMs are ammo previous designs zach’s michael’s

  5. payloadtechnology • SMMs has a battery, microprocessor, a seismometer, and a UHF transmitter • Continuously collect data and beam back when orbiter passes overhead • 16 samples/second, 720 bits/second, 50 mb/week

  6. physicsbreakdown • Solved for tangential velocity • Found impact velocity from tangental velocity • From impact velocity, found the penetration depth and deceleration • From deceleration and Europa’s gravitational constant, found g-force SMM must sustain

  7. thank you. questions or comments?
