update Definition (orer 24 was placed in orbit together with Explorer 25 from a single launch vehicle.  Explorer 24 was identical in configuration to the previously launched balloon satellites Explorer 9 and 19.  The spacecraft was 3.6 m in diameter, was built of alternating layers of aluminum foil and plastic film, and was covered uniformly with 5.1-cm white dots for thermal control.  It was designed to yield atmospheric density near perigee as a function of space and time from sequential observations of the sphere's position in orbit.  To facilitate ground tracking, the satellite carried a 136-MHz tracking beacon.  The satellite reentered the earth's atmosphere on October 18, 1968.
