2. AAE450 Spring 2009 10 Kilogram Payload Breakdown  The 10 kg payload architecture is a soft landing with the main Lunar Lander engine. At this point the 500 meter locomotion will occur using one 200 N hybrid thruster.  Mass Breakdown –Wet Mass in LLO (w/ payload) – 228.13 kg –Mass on Lunar Surface (Pre-Hop) – 115.6 kg –Dry Mass on Lunar Surface (Post-Hop) – 106.9 kg [Josh Lukasak] [Attitude] (2)

3. AAE450 Spring 2009 Arbitrary Payload [Josh Lukasak] [Attitude] (3)  The arbitrary payload mission architecture involves a descent trajectory that hovers over the lunar surface and translates the 500 meters at a set height before finally touching down. Given 3542 kg deliverable to LLO.  Mass Breakdown –Wet Mass in LLO (w/o payload) – 2248.93 kg –Dry Mass of the Lander – 465.31 kg –Deliverable Payload – 1293.07 kg

5. AAE450 Spring 2009 100 Gram Payload  The 100 gram payload mission architecture for the Lunar Lander involves the delivering of two roving balls to the lunar surface.  Mass Breakdown –Wet Mass in LLO (w/ payload) - 155.97 kg –Dry Mass on Lunar Surface – 72.93 kg [Josh Lukasak] [Attitude Group Lead] (5)
