versa. In this case, two engineers quickly found their new responsibilities deep in many aspects 
of mass properties engineering and required to meet technical challenges in a fast paced 
environment.  As part of NASA’s Constellation Program, a series of flight tests will be conducted 
to evaluate components of the new spacecraft launch vehicles. One of these tests is the Pad Abort 
1 (PA-1) flight test which will test the Launch Abort System (LAS), a system designed to provide 
escape for astronauts in the event of an emergency.  The Flight Test Articles (FTA) used in this 
flight test are required to match mass properties corresponding to the operational vehicle, which 
has a continually evolving design.  Additionally, since the structure and subsystems for the Orion 
Crew Module (CM) FTA are simplified versions of the final product, thousands of pounds of 
ballast are necessary to achieve the desired mass properties.  These new mass properties 
engineers are responsible for many mass properties aspects in support of the flight test, including 
meeting the ballasting challenge for the CM Boilerplate FTA. SAWE expert and experienced 
mass properties engineers, both those that are directly on the team and many that supported via a 
variety of Society venues, significantly contributed to facilitating the success of addressing this 
particular mass properties ballasting challenge, in addition to many other challenges along the 
way.   This paper discusses the details regarding the technical aspects of this particular mass 
properties challenge, as well as identifies recommendations for new mass properties engineers 
that were learned from the SAWE community along the way.</style></abstract><call-num><style face="normal" font="default" size="100%">3497</style></call-num><custom1><style face="normal" font="default" size="100%">Non-Member Price: $17.01.
