Terrier Orion
American sounding rocket
The Terrier Orion sounding rocket is a combination of the Terrier booster rocket with the Orion rocket used as a second stage. This spin stabilized configuration is most often used by the Goddard Space Flight Center, who operate out of the Wallops Flight Facility for sounding rocket operations.[1] The system supports payloads ranging from 200 to 800 pounds (90 to 360 kg), and is capable of achieving altitudes as high as 120 miles (200 km), but at least 50 miles (80 km), depending on payload size.[2]
