sentences:  The CM/LAS simulator was built with high fidelity to ensure that its hardware components accurately reflect the shape and physical properties of the models used in computer analyses and wind tunnel tests.This precision enables NASA to compare CM/LAS flight performance with preflight predictions with high confidence.The CM/LAS simulator also helps verify analysis tools and techniques needed to further develop Ares I.
  
  Ares I-X flight data were collected with sensors throughout the vehicle, including approximately 150 sensors in the CM/LAS simulator that recorded thermal, aerodynamic, acoustic, vibration and other data.
