ATK Achieves 'Significant Milestone' As Booster Integrator
NASA and ATK have successfully completed two key avionics tests for the solid rocket boosters for the space agency's new heavy lift rocket, the Space Launch System (SLS). The avionics tests, called hot fires, operate the booster's thrust vector control (TVC) system as if the booster were actually launching the SLS on a mission. The tests were conducted at ATK's Promontory, Utah, facility.
