LPI-JSC Center for Lunar Science & Exploration 2011Impact EjectaVertical Impact Experiment

Transient crater reaches its maximum depth before it reaches its maximum diameter

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.
