The DOE Lab Director's Conference identified the need for the DOE National Laboratories to actively and aggressively pursue ways to apply DOE technology to problems of national need. Space structures are key elements of DOD and NASA space systems and a space technology area in which DOE can have a significant impact. LASC is a joint agency space technology experiment (DOD Phillips, NASA Marshall, and DOE Sandia). The topics are presented in viewgraph form and include the following: phase 4 investigator testbed; control of large flexible structures in orbit; INFLEX; Controls, Astrophysics; and structures experiments in space; SARSAT; and LASC mission objectives

• The DOE Lab Director's Conference Identified the need for the 
DOE National Laboratories to actively and aggressively pursue 
ways to apply DOE technology to problems of National need. 
• Space structures are key elements of DoD and NASA space systems and 
a space technology area In which DOE can have a significant Impact. 
• LASe Is a Joint agency space technology experiment. 
(000 Phillips, NASA Marshall, DOE Sandia) 
• Total cost Is $35 Million spread over a 3 year project life. 
• We are seeking concurrence among the three participating 
agencies (DoD, NASA, DOE).

LAse Mission Objectives 
• On-orbit modal testing and system Identification for comparison to similar data obtained via ground testing and simulation. 
• Conduct controls experiments In the areas of v ibration suppression, pointing, slewing, disturbance reJection, and deployment & 
retrac tion stabilization to the degree possible. 
• Employ active/passive damping elemonts within the structure to 
assess their effectiveness. 
• Examine variable structure conf igurations control. 
• Provide an on-orbit Guest Investigator laboratory.
