The launch time frame is from noon to 5 p.m. The Minotaur IV will launch the Defense Advanced Research Projects Agency's Falcon Hypersonic Technology Vehicle 2. The Falcon HTV-2 will fly a hypersonic glide trajectory within the earth's atmosphere to a broad-ocean area impact point near the Reagan Test Site in the Kwajalein Atoll, Republic of the Marshall Islands. DARPA's Falcon HTV-2 program seeks to demonstrate advances in high lift-to-drag aerodynamics; high-temperature materials; thermal protection systems; and advanced guidance, navigation and control. The Minotaur IV Launch Vehicle is the newest variant in the Minotaur family of rockets built by Orbital Sciences Corporation. The Minotaur IV is a four-stage solid rocket vehicle consisting of three decommissioned Peacekeeper missile stages and a fourth, commercially-built stage developed by OSC. The rocket is designed to place a payload weighing up to 1,735 kilograms into low-Earth orbit. 30th Space Wing commander Col. David Buck is the launch decision authority.
