There are two Air Force Research lab people at Kirtland AFB, N.M., whose task is to advance “multiple methods” to design, develop, and produce low-cost rockets. Officials say that the Launch Vehicle Technology program has “fueled” many efforts, some dating back more than 10 years, such as a Microcosm Inc. rocket called Scorpius.
