• 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

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

payloadtechnolog
y
• 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

• 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
