VT-1 followed the successful launch of Vanguard VT-0 a one-stage rocket launched in December 1956.Project Vanguard was a program managed by the United States Naval Research Laboratory (NRL), and designed and built by the Glenn L. Martin Company (now Lockheed-Martin), which intended to launch the first artificial satellite into Earth orbit using a Vanguard rocket. as the launch vehicle from Cape Canaveral Missile Annex, Florida.Vanguard TV-1 arrived at Cape Canaveral in February 1957. TV-1 was a two-stage rocket. Vanguard TV-1 used a liquid rocket booster from a modified Viking rocket for the first stage. The second stage was made by Grand Central Rocket Company. The second stage was a prototype solid-propellant rocket. This solid-propellant second stage later became the third stage of the finial three stage Vanguard vehicle. Three stages are needed to put a satellite in orbit, the goal of Vanguard.Vanguard TV-1 lifted off on May 1, 1957 at 1:29 a.m from Cape Canaveral from launch pad 18A. Launch pad 18A was an older Viking launch stand that was shipped from White Sands Missile Range for use at the Cape Canaveral. Pad 18A was also used on Vanguard Test Vehicle zero.The main goal of Vanguard TV-1 was to test the solid-propellant rocket. The solid-propellant rocket needed to spin-up, separate from the first stage booster, ignite, provide a proper propulsion and trajectory. Another goal was to test the techniques and equipment used to launch and track the rocket. The telemetry received during flight would record the proper propulsion and trajectory. The telemetry was picked up at the Air Force Missile Test Center's (AFMTC) tracking station.Vanguard TV-1 was successful, the two stage rocket achieved an altitude of 121 mi (195 km) and a down range of 451 mi (726 km), landing in the Atlantic Ocean.With Vanguard TV1 and Vanguard TV0 success, the next sub-orbital test flight, Vanguard TV2, was launch on October 23, 1957."@en }
