In 1927, E.O. Hulburt of the US Naval Research Laboratory and associates Gregory Breit and Merle Tuve of the Carnegie Institution of Washington explored the possibility of equipping Robert H. Goddard's rockets to explore the upper atmosphere. "Two years later, he proposed an experimental program in which a rocket might be instrumented to explore the upper atmosphere, including detection of ultraviolet radiation and X-rays at high altitudes." This became a part of the History of X-ray astronomy.
