Study of Vertically Incident Cosmic-Ray Trajectories Using Sixth Degree Simulations of the Geomagnetic Field-consisting largely of computer-generated tables of cosmic-ray trajectories at more than 130 locations around the world-was issued by AFCRL. Since cosmic ray trajectories are directly influenced by the configuration of the magnetic field, which varies diurnally, seasonally, and with solar-cycle variations, it was possible to derive information on the changing magnetic field by observing cosmic-ray events. Also, because calculations of cosmic-ray rigidities are equally valid for solar protons, calculation techniques developed under this study could be used to evaluate the trajectories of these solar particles as well. ‘‘(OAR Res.

Thirtieth anniversary of Jet Propulsion Laboratory of Cal Tech. In March 1936 Dr. Theodore von Karman approved initiation of rocket propulsion studies by Frank J. Malina with the assistance of John W. Parsons and Edward S. Forman at the Guggenheim Aeronautical Laboratory. ‘‘(NASA Historian)’’
Seven French-built Centaure rockets carrying experiments for study of polar auroras were successfully launched in February and March by ESRO from base at Andoeya, Norway. ‘‘(M&R, 4/11/66, 7)’’
