Summary
Explorer 24 & 25 launched on a National Aeronautics and Space Administration Scout X-4 from Space Launch Complex 5, Vandenberg SFB, CA, USA on November 21, 1964. It was National Aeronautics and Space Administration's 60th launch, 11th this year and humanity's 381st orbital launch attempt. It was the 8th Scout X-4 flight and the 6th this year. The payload was bound for Elliptical Orbit (Elliptical). Explorer 24, one of 13 catalogued objects, reached a 546 × 2,495 km orbit inclined 81.3°. 13 objects from this launch are catalogued, 2 of them payloads.

About this launch
Explorer 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.
