This Study was produced by the Air Force Scientific Advisory Board. It was requested by the Commander Air Force Space Command and approved by the Secretary and Chief of Staff of the Air Force. It covers three topics, each of sufficient depth to be study of its own: Space Surveillance, Asteroid and Comet Impact Warning for Earth, and Space Debris. Space Surveillance is the unifying theme. Space Surveillance is a ...

This Study was produced by the Air Force Scientific Advisory Board (SAB). It was requested by the Commander Air Force Space Command and approved by the Secretary and Chief of Staff of the Air Force. It covers three topics, each of sufficient depth to be a study of its own: Space Surveillance, Asteroid and Comet Impact Warning for Earth, and Space Debris. NASA personnel predicted in 1978 that collisional cascading ...

The horizontal components of an oscillating magnetic dipole immersed in a semi-infinite conducting medium were determined using the most general expressions available. The fields of interest were those beneath the surface of the conductor. An experiment was designed and performed to measure the y-component of the magnetic field created by a small y-oriented loop antenna located beneath the surface of a conducting half-space. The fields were measured beneath the surface ...
