Atmospheric collection of debris from the Revelstoke and Allende fireballs Atmospheric collection of debris from the Revelstoke and Allende fireballs

In two separate events, Revelstoke and Allende, the air through which a fireball had been observed to pass was sampled for meteoritic debris. Particulate matter was collected on fibrous filters, which were mounted on aircraft and flown downwind from the site of the meteorite fall at altitudes of 10,000–12,000 m. From Revelstoke, a highly distinctive assemblage of particles was collected...

Preliminary geologic investigation of the Apollo 12 landing site: Part B: photometric and polarimetric properties of the lunar regolith Preliminary geologic investigation of the Apollo 12 landing site: Part B: photometric and polarimetric properties of the lunar regolith

Several special, as well as general, photometric and polarimetric studies of the lunar regolith in the vicinity of the Apollo 12 landing site have been undertaken by means of the black-and-white photographs obtained on the geologic traverse during the second extravehicular activity (EVA) period.

The Alaska earthquake, March 27, 1964: Lessons and conclusions The Alaska earthquake, March 27, 1964: Lessons and conclusions

One of the greatest earthquakes of all time struck south-central Alaska on March 27, 1964. Strong motion lasted longer than for most recorded earthquakes, and more land surface was dislocated, vertically and horizontally, than by any known previous temblor. Never before were so many effects on earth processes and on the works of man available for study by scientists and engineers over so...
