Since 1980, ADL has tested nearly every nutationally unstable (inertia ratio less than one) spacecraft launched on a Delta II rocket with a spinning third stage. For many of these programs, tank baffles were designed and tested to increase the nutational time constant.

WHAT ADL CLIENTS SAY: 

“The spacecraft for which you supported us now include the Mars Global Surveyor, Mars Climate Orbiter, Stardust and the Mars 2001 Orbiter. In each case, your outstanding technical expertise and rigorous test discipline yielded data in which we were confident. Your responsiveness to our compressed schedules and changing requirements allowed us to meet our deadlines. The effort that you put into your testing in support of these projects is deeply appreciated ... .”
—Lockheed Martin

“[Regarding the Lunar Reconnaissance Orbiter] NASA has determined that Applied Dynamics Laboratories is the only vendor which can provide [drop tower] testing and is the only research group that has the experience of developing scaled models to match a number of dimensionless parameters needed to assure proper scaling between the model and the flight hardware ... [and] can deliver with the current urgency... .”
