LPI-JSC Center for Lunar Science & Exploration 2011Impact EjectaOblique Impact Experiment
The ejecta is asymmetrically distributed
The impact trajectory is from _______ to _______
This is part of an on-line laboratory exercise available at http://www.lpi.usra.edu/nlsi/education/hsResearch/crateringLab/

This experiment has an aluminum plate with holes that split the ejecta curtain into packets. This allows one to focus on isolated components of the ejecta curtain and see that they are on a looping ballistic trajectory
This, too, is part of the on-line laboratory exercise. Both components take 1 to 2 hours to complete.
