| | NRL - Viking Program |
 | | Viking embodied the successful, important innovations of a gimballed motor for steering and intermittent gas jets for stabilizing the vehicle after the main power cutoff. |
 | | Through these Viking firings, NRL was first to measure temperature, pressure, and winds in the upper atmosphere and electron density in the ionosphere, and to record the ultraviolet spectra of the sun. |
 | | On October 5, 1954, during a launching over New Mexico, a camera mounted in an NRL Viking rocket took the first picture of a hurricane and a tropical storm, from altitudes as high as 100 miles. |
