Six displacement-controlled, conventional, drained axisymmetric triaxial experiments on cohe sionless granular soil specimens were conducted at very low effective confining stresses in a SPACEHAB module on the Space Shuttle during the STS-79 and ST

Computed Tomography (CT) is being used to investigate the complex internal structure of axisymmetric (triaxial) sand specimens. A series of triaxial experiments was conducted on dry Ottawa sand specimens at very low effective confining stresses in a

The constitutive behavior of soils such as strength, stiffness, and localization of deformations are to a large extent derived from interparticle friction transmitted between solid particles and particle groups. Interparticle forces are highly depend

Soil mechanics and geological investigations on Mars or on the Moon are described herein, using a novel mobility system, designated as the "Elastic Loop Mobility System (ELMS)". ELMS was developed as a spin-off of the U. S. Lunar Roving Vehicle (LRV)

The microgravity environment induced by near-earth orbits of spacecraft, along with the hard-vacuum, of space through the use of a wake shield, provide unique experimental opportunities for testing theories related to the mechanical behavior of terre

Data were extracted from astronaut observations, television coverage of the moon walk, and returned photographs and samples. It has been determined that the upper few centimeters of the lunar soil in the vicinity of Tranquility Base are characterized

The Apollo 14 lunar landing provided a greater amount of information on the mechanical properties of the lunar soil than previous missions because of the greater area around the landing site that was explored and because a simple penetrometer device,
Synopsis During the sojourn of the second manned space-craft on the moon in Sovember 1969, the astronauts C. Conrad and A. Bean performed a number of tasks of interest from a soil mechanics point of view. They crossed the lunar surface, penetrating i
