2012, a test area at MSFC was developed and the Mighty Eagle tested "Autonomous
Rendezvous and Capture" technology. In 2013, enhancements were made including legs that are lighter by about 6.8 kg (15 lbs), a 3D stereo camera that allows the detection and avoidance of 3D (three dimensional) objects and an onboard image processor in preparation for "hazard avoidance" testing.

The design of the vehicle began in late 2009 and integration was completed in
January 2011. The vehicle was transported to an indoor test facility and bolted to the ground for initial testing, followed by free flight testing. Outdoor testing at another facility ran from August to November 2011. In
