The database darpa is building records more than just information about the blast waves.
darpa calls its new project the XS-1, for Experimental Spaceplane.
But nobody connected with the darpa (Defense Advanced Research Projects Agency) Robotics Challenge wants to admit that.
In late 2009 Borkholder wrote a white paper proposal to darpa that pitched a disposable blast gauge using a tiny pressure sensor.
Both projects were funded by a Defense Advanced Research Projects Agency, or darpa.
But darpa has learned that wavefronts move tangentially along walls as well.
One organization investigating these questions is the Defense Advanced Research Projects Agency, better known as darpa.
“darpa has been taking the data from every explosive event in theater,” says Borkholder.
