Roy Healy

Healy guided the North American Jupiter engine program.^[2] He contributed to many World War II rocket installations. In 1946, he was named vice president of the American Rocket Society.^[3] The American Rocket Society was a group committed to the research and development of jets and rockets.^[4] A 23.9 kilometer crater on the moon was named after Healy, now titled Healy Crater.^[1] He was a key contributor to research on rockets and jet propulsion throughout his life.^[5] Healy's research and insight provided valuable information on rockets and jet propulsion that could be used for military purposes.^[6]

As a rocket scientist, Roy Healy wrote articles and had them published in various publications. Many of them pertained to rocket power and use during World War II.

• "Thrust of Powder Rocket Charges: Commercial Types Tested", published in 1941.^[7] Healy is describing data and research on different types of rockets.^[7]

• "The Nazi Rocket Threat: Giant Projectiles Awaiting Invasion", published in 1944.^[8] Healy writes to warn of the threat posed by Nazi rockets. He is arguing that the story posed about the Nazi's having rockets prepared and ready to launch is true, and any skepticism should be eliminated.^[8]

• "Nazi Rocket Weapons: Jet Power Widely Used by Germany" published in 1943.^[9] The article is about different types of jet power and rockets used by Nazi Germany during World War II.^[9]

• "The Black Powder Rocket Charge: Its Military Uses" published in 1942.^[10] Healy discusses types of rockets used during the first world war, and then progresses to discuss more modern types of rockets for the time period.^[10]
