NASA announced Astronaut John A. Lewellyn had withdrawn from as­tronaut training program because of inability to progress sufficiently with jet flight training at Reese AFB, Tex. After discussions with NASA and USAF officials, he had withdrawn to consider several opportunities within NASA and elsewhere. His departure reduced total number of NASA astronauts to 52. Nine of eleven scientist-astronauts selected in 1967 were in flight training. Dr. Brian T. O'Leary had withdrawn April 23 because he disliked flying. (MSC Release 68-63; AP, NYT, 8/24/68, 12)

Dr. Alan H. Barrett and Dr. William J. Wilson of MIT reported in Sci­ence discovery of hydroxyl radio emissions from four infrared stars in Cygnus constellation, observed from National Radio Astronomy Observ­atory in West Virginia. They speculated that emissions indicated defi­nite stage in stars' evolution. (The older a star gets the hotter it be­comes, until it has almost no oxygen and hydrogen.) Further studies, supported partially by NASA, would be conducted during next few years in attempt to determine how far young stars had progressed in process of evolution by observing hydroxyl emissions.
