Argo sounding rockets measured radiation caused by the Project Argus high altitude nuclear explosions. The missiles reached 800 km altitude, launched from Wallops Island, AMR, and Ramey AFB, Puerto Rico.
In 3-week period, 19 five-stage Argo E5 sounding rockets were launched in USAF-NACA program to measure radiation caused by Project Argus, rockets reaching 500-mile altitude and were launched from Wallops Island, AMR, and Ramey AFB, Puerto Rico.
Four-stage Argo D4 rocket with an ARDC Javelin payload fired from Wallops Island to an altitude of 750 miles, first in a series of USAF-NASA launchings to measure natural radiation surrounding the earth.
NASA Argo D-4 rocket was launched from Wallops, reaching an altitude of 585 miles and landing 817 miles out in the Atlantic, to gather data on the density of electrically charged helium atoms in the upper atmosphere.
