Thor-Delta

Thor-Delta is a launch vehicle that was used by the National Aeronautics and Space Administration (NASA) and the United States Air Force (USAF) for a variety of missions, including launching Intelsat satellites, Explorer program spacecraft, and Tiros weather satellites. The Thor-Delta was a modified version of the Thor missile, which was developed by the Douglas Aircraft Company and first launched in 1958. The Thor-Delta was used for a number of notable missions, including the launch of the Telstar 1 communications satellite and the Ranger 4 lunar impactor. The Thor-Delta was also used to launch a number of NASA spacecraft, including the Mariner 2 and Mariner 5 missions to Venus.

Introduction

The Thor-Delta launch vehicle was developed in the late 1950s and early 1960s by the Douglas Aircraft Company and the NASA Goddard Space Flight Center. The Thor-Delta was a modified version of the Thor missile, which was developed by the USAF and first launched in 1958. The Thor-Delta was designed to be a more powerful and reliable launch vehicle than the Thor, with a number of upgrades and modifications, including a new second stage and a more powerful engine. The Thor-Delta was used for a variety of missions, including launching Intelsat satellites, Explorer program spacecraft, and Tiros weather satellites, and was also used by the European Space Agency (ESA) and the Canadian Space Agency (CSA). The Thor-Delta was launched from Cape Canaveral Air Force Station and Vandenberg Air Force Base, and was also used to launch a number of NASA spacecraft, including the Mariner 2 and Mariner 5 missions to Venus, and the Ranger 4 lunar impactor.

Design and Development

The Thor-Delta launch vehicle was designed and developed by the Douglas Aircraft Company and the NASA Goddard Space Flight Center. The Thor-Delta was a modified version of the Thor missile, which was developed by the USAF and first launched in 1958. The Thor-Delta had a number of upgrades and modifications, including a new second stage and a more powerful engine, and was designed to be a more powerful and reliable launch vehicle than the Thor. The Thor-Delta was also designed to be more flexible and adaptable than the Thor, with a number of different payload fairings and adapters available. The Thor-Delta was used by a number of different organizations, including NASA, the USAF, the European Space Agency (ESA), and the Canadian Space Agency (CSA), and was launched from a number of different launch sites, including Cape Canaveral Air Force Station and Vandenberg Air Force Base. The Thor-Delta was also used to launch a number of notable spacecraft, including the Telstar 1 communications satellite, the Ranger 4 lunar impactor, and the Mariner 2 and Mariner 5 missions to Venus, which were managed by the Jet Propulsion Laboratory (JPL) and the NASA Ames Research Center.
