Successful Orion Tests. Aurora Sciences has successfully tested components that will be integrated into its Orion unmanned aircraft system. Air Force spokeswoman Jennifer Cassidy says from Jan. 24-28, 2012, Aurora completed the engine 120-hour ground endurance test. “Integrated Orion system tests are scheduled to take place by the end of 2012,” Cassidy says. According to Aurora Chief Technical Officer and Vice President of Development Programs Tom Clancy, the Orion is a “much larger aircraft” that the company is trying to make capable of staying in the air, between take off and landing, for five days.
