BREAKTHROUGH INTO SPACE
Abstract
The materials for the body of the spaceship should protect the crew from the cosmic vacuum, withstand erosion when the skin is bombarded by cosmic dust, and withstand the impacts of small meteorites. A group of very refractory metals which must be heated to 3000 degrees and higher to be melted include Be, Nb, Mo, Ta, and W. The properties of these metals are discussed. (Author)
