ABOUT HIS ROCKET TO THE MOON. ROBERT H. GODDARD. Historically Important TLS: "R.H. Goddard", 1p, 8¼x11. Clark College, Worcester, Mass., 1921 March 7. To William L. Straus, Jr., Baltimore. On stationery listing Goddard and C.E. Melville as Professors in the Department of Physics of Clark College. In full: "In reply to your letter of March 3, I might say: 1) The work at present is confined to the construction of a small model and there is no immediate prospect of financing anything more than this. 2) Regarding your second question, I admit that there is no oxygen in the atmosphere on the moon, but beg to call attention to the fact that any of the commercial flash powders contain an oxygen-carrying compound, which is usually potassium chlorate. The experiment which has been given considerable publicity took this fact into account, the flashes being exploded in a glass container in which the pressure had been reduced to about 1/60 of atmospheric pressure." Goddard began experimenting with rockets in 1908, when he demonstrated that rockets could operate in a vacuum. In 1914, Goddard received two U.S. patents. One was for a rocket using liquid fuel. The other was for a two or three stage rocket using solid fuel. read more...
