He is less easily known than Wernher von Braun or Theodore von Kármán in a rocket program and the origins of JPL. Yet, von Braun remarked that Parsons, & non he, should exist when regarded as a father of the U.s. space program [http://www.disinfo.com/pages/article/id592/pg1/].

Parsons was as well an inspiring practician of the occult arts, and the follower of Thelema. He was chosen by Aleister Crowley to lead the Thelemic Ordo Templi Orientis (O.T.O.) in California in 1941. He was besides a erstwhile magickal partner of L. Ron Hubbard. Them participated within a ritual called the Babalon Working which is famous inside occult circles — loosely, an attempt to summon a goddess & vary the course of history. This relationship lasted until 1947, when Hubbard defrauded Parsons of the total of money (& ran off by having his girlfriend). Reciprocally, Parsons failed to notify Hubbard that he got received a letter from either the United States Navy informing Hubbard of his long-coveted promotion to the rank of lieutenant commander [http://www.salon.com/tech/books/2000/02/15/parsons/index.html].

Jack Parsons died within 1952 in a laboratory explosion which is typically repute accidental. An extensive low library of his germinal writings on a Babalon Working has been maintained since 1997 at http://www.babalon.net.

The crater on the far side of the Moon has been named fallowing him.
